Description

Implementation method of multi-window web page synchronization

technical field

The invention relates to the technical field of data communication, in particular to a method for realizing multi-window webpage synchronization in the information webpage synchronization technology based on the Internet.

Background technique

Generally, webpage synchronization or webpage sharing can also be called escort browsing, which means synchronizing the webpage browsing content of the customer with that of the operator, or synchronizing the webpage browsing content of the operator with that of the customer, so as to realize synchronous webpage browsing from the client to the agent side. During synchronization, both parties will see the same web page content on the browser. Escorted browsing can be used by the operator to "push" product introductions to customers on the network and provide services such as synchronous browsing and navigation. It can be widely used in the World Wide Web (Web) integrated call center, online customer service center, e-commerce shopping guide system, personal or enterprise interactive contact products, remote demonstration and distance education and other products.

Existing web page synchronization or web page sharing roughly has the following implementation methods:

Solution 1: Both the client and the agent end download a small application, and open a browser window for real-time monitoring. When the URL of one of the client or the agent changes, the small application After the change is detected, the other party's applet is notified through the network to synchronize its browser window to the URL.

Solution 2: Start an application program on the web server to monitor the URL requests sent to the web server by the client and the agent. At the same time, the web page contains a control frame to continuously detect the status of the web server. When the URL of one of the clients or the agent changes, the web server changes the current state after detecting the change, and the other party's control frame synchronizes its browser window to that URL.

Existing web page synchronization technology has the following defects:

1. The existing technology only supports the synchronization of a single window, but at present, it is often necessary to open multiple browser windows for browsing when browsing web pages at most Web sites.

2. Cannot realize synchronous browsing of multiple Web sites at the same time.

3. Insufficient support for multi-frame webpages. Some web sites contain multi-frame webpages. At this time, there may be a phenomenon that the frames in the browser window cannot be synchronized.

4. The prior art cannot handle webpages containing dynamic sub-windows. A dynamic sub-window refers to a web page containing a sub-window request pointing to a Common Gateway Interface (CGI) program. Every time you visit the sub-window of the web page, different content will be generated (for inserting advertisement screens in the web page), which may easily cause synchronous pages. is replaced by this subwindow, so that web synchronization cannot continue.

5. It is necessary to customize the web pages on the web server, and even the web pages on the web servers other than the source web server cannot be synchronized.

6. Lack of flexible control over the direction of synchronous browsing.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a method for realizing multi-window webpage synchronization, so that it can support multi-window webpage synchronization and multi-frame webpage synchronization, and can filter redundant webpages, flexibly control webpage browsing, and then It facilitates the user's operation and the management and maintenance of the server.

In order to achieve the above object, technical solution of the present invention is achieved in that way:

A method for realizing synchronization of multi-window webpages, it is important that the method at least includes the following steps:

Create multiple synchronous window event processing threads and corresponding multiple synchronous window event receivers, trigger synchronous window event receivers by external program calls or synchronous browser window actions, and perform related operations in their corresponding synchronous window event processing threads deal with;

Assign different synchronization window event processing threads to different synchronization windows, so that actions in different windows are processed in different synchronization window event processing threads.

When a page synchronization window for web page synchronization is initiated, a synchronization window event processing thread is assigned to the synchronization window.

When any one of both sides of the synchronization opens one or more new browser windows in a synchronization window, the synchronization window event processing thread request assigns a new synchronization window event processing thread to the new window, and simultaneously activates a The multi-window interception call processor performs interception calls for new windows.

When the synchronization action or new window action in the synchronization window is intercepted, the synchronization window event processing thread sends the synchronization information to the other party.

The synchronization window event processing thread further filters redundant window information and then sends the synchronization information to the other party. The redundant window information includes but not limited to redundant address information and dynamic advertisement sub-window address information.

The synchronization information at least includes: a synchronization window URL address message; a synchronization window closing message; a page synchronization end message; or a synchronization mode control message.

The window synchronization information further includes synchronization methods of webpage synchronization, including one-way synchronization or two-way synchronization, manual synchronization or automatic synchronization, and a combination of the two synchronization methods. The window synchronization information includes but is not limited to page push synchronization, synchronous browsing, multi-frame synchronization, new window or multi-window synchronization, synchronization operation, local directory browsing synchronization, sending email click synchronization, HTTP-based FTP synchronization, window closing synchronization, end Web page synchronization and synchronization of internal elements or objects of a web page.

When creating a new synchronization window, establish an event connection between the synchronization window and a synchronization window event receiver; or connect the new window with the synchronization window event processing thread, and set the thread as the synchronization event of the new window receiver.

The user and the server can use the present invention to share webpage information through the network, or browse the webpage synchronously, so that the server can provide users with demonstrations of various webpage information, such as product information, educational content, and the like. Moreover, the server can be one-to-one or one-to-many to users, and is not restricted by synchronous browsing of a single window. The dynamic intercepting new window technology provided by the present invention can also automatically enter a new synchronous window by clicking on a new window link on the synchronous window.

In addition, users can operate the webpage to seek help from the service provider. At the same time, the multi-window webpage synchronization technology can also be used as the basis for further webpage information sharing technology, such as sharing more data in the webpage.

Users can also browse webpages synchronously with each other through multi-window webpage synchronization technology, and both parties can exchange webpage information and website favorite content.

It can be seen that the realization method of multi-window web page synchronization provided by the present invention has the following functions and advantages:

1. The present invention not only supports the synchronization of a single window, but also supports the synchronization of multi-window webpages. Often need to open a plurality of browser windows to browse when most Web sites browse webpage at present, these newly opened webpage windows can all be intercepted and fully controlled by the system provided by the present invention, and new synchronous window possesses all functions of former synchronous window , including the ability to intercept more new sync windows on it.

2. Support multi-frame web page synchronization. For a web site containing multiple frames of web pages, the synchronization of the multiple frames of web pages can also be performed.

3. Realize synchronous browsing of multiple Web sites at the same time, and support web page synchronization for web pages that span domain names and hosts.

4. It has the function of synchronous window filtering, including redundant frame filtering, dynamic sub-window and other filtering functions. Wherein, the dynamic sub-window refers to that the web page contains a sub-window request pointing to a CGI program, and each access to the sub-window of the web page will produce different content (for inserting an advertisement picture in the web page). The invention solves the problem that the synchronization page may be replaced by the sub-window during the operation, so that the synchronization of the web page cannot continue, so that the invention is suitable for connecting with any Web site on the INTERENT without any special custom processing.

5. Support the flexible control of web page synchronous browsing direction. No matter which party dominates the webpage synchronization, one of them (generally the server or the operator) can ultimately control all two-way interactions. Great convenience for users to carry out effective synchronous control.

6. It has a variety of synchronous control functions. Such as: support page push synchronization function, synchronous browsing function, multi-frame synchronization, new window or multi-window synchronization, synchronization operation function, local directory browsing synchronization, send email click synchronization, file transfer protocol based on hypertext transfer protocol (HTTP) ( FTP) synchronization, window close synchronization, end webpage synchronization, and even synchronization of internal elements or objects of a webpage. Among them, when the synchronization window is closed, the other party will prompt whether to perform the same closing operation, and will prompt whether to close all synchronization windows when the webpage synchronization is ended; and the existing system only has simple push and synchronization functions, which is far from satisfying the requirements of electronic communication. Business shopping guide, online customer service, electronic service and other new business needs.

7. The webpage synchronization of the present invention can cooperate with any other call media types, such as: webpage synchronization can be combined with webpage click-to-talk, text chat, and Web callback request calls, and after the call is established, press the "escort browsing" button on the webpage , the other party will see the same web content. After that, the content of the web page will be synchronized until the "End Browsing" button is pressed.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to FIG. 1 , the system structure diagram of multi-window page synchronization based on webpage synchronization in the present invention. The interface method part in the figure refers to the software interface provided by the web page synchronization control to the external program call. The cooperative control unit shown in the figure can realize the main functions including: start web page synchronization; receive external messages and control messages; set Relevant configuration parameters; obtain the status information of the webpage synchronization control; end the webpage synchronization, etc.

Among the above-mentioned functions, the most important ones are the functions of receiving external messages and controlling messages, which include interface methods such as page push synchronization, window close synchronization, and so on. Relevant external messages or control messages are sent to the control for processing through this interface function. Such as: the page synchronization message sent by the other party, so that the control can perform further processing according to the message, and realize webpage synchronization actions such as page push synchronization, synchronous browsing function, and window closing synchronization. Wherein, the processing flow of the synchronization window push interface method of the webpage synchronization control is shown in FIG. 4 ; the specific flow of the webpage synchronization control synchronization window closing interface method processing is shown in FIG. 5 .

Synchronization messages include the following message categories: synchronization window URL address message, specified window number; synchronization window close message, specified window number; page synchronization end message; and synchronization mode control message, etc.

As shown in Fig. 1 and Fig. 2, the system structure of multi-window page synchronization of the present invention specifically includes the following process in terms of functional processing:

1) The two sides of the user generally refer to: the server side and the user side, the agent side and the terminal user side, or both sides are the user side, respectively use a browser to enter the web page synchronization system of the present invention.

2) If entering for the first time, the browser will automatically download a multi-window web page synchronization module (i.e. ActiveX control) and load and execute. This ActiveX control, the control module of web page synchronization of the present invention, will create a plurality of web page synchronization threads during operation. The number of synchronization threads can be defined flexibly, and the synchronization thread is mainly responsible for monitoring the actions and events of the synchronization window.

3) In this state, the webpage synchronization control waits for the external program to receive the user's request to start webpage synchronization. After receiving the user's request, the cooperation control unit calls the control's start webpage synchronization interface method.

4) After the user sends a page synchronization call request to the server, the server receives the call and establishes a page synchronization channel, and then initiates a page synchronization window to start the page synchronization of web page synchronization, that is, assigns a synchronization thread to the page synchronization Synchronize windows.

5) When the user or server performs a browsing action or push action, the synchronization thread will intercept the action and event;

6) Then the synchronization thread sends the synchronization information to the other party after filtering out redundant window information; redundant window information refers to redundant frame address information and dynamic advertisement sub-window address information. Since the webpages in many websites often have multi-frame pages and dynamic advertisement sub-window address information generated by CGI programs, these are all additional address information associated with the main URL. Generally, such address information does not need to be sent to the other party and must be filtered out. Otherwise, a useless window will be generated and the original window will be covered.

7) When the other party receives the synchronization information, the corresponding synchronization thread controls the synchronization window to perform corresponding synchronization browsing actions.

8) When one of the parties executes actions such as multi-window, multi-frame, closing a synchronization window, and ending web page synchronization, the other party can receive the message and handle it accordingly.

9) When one party opens one or more new browser windows in a synchronous window, the synchronous thread will request to allocate a new synchronous thread to the new window, and activate a multi-window interception call processor to carry out the new window at the same time. intercepted calls.

10) The multi-window interception processor executes the interception processing action in the newly allocated thread, which has been separated from the original thread control at this moment;

11) The new synchronous window processing thread searches for a new window, and when the new window is intercepted, the synchronous window number is displayed on the title bar, and the information intercepted by the synchronous thread is notified to the other side; the new synchronous window processing thread is the same as the original synchronous window The processing thread is generated by the same class, which is a synchronous window event processing class.

12) The other party creates a corresponding new page synchronization window, the content of the page is the same as it, and the synchronization window number is added on the title bar; the new synchronization window has all the functions of the original synchronization window, including intercepting more new synchronizations on it The function of the window.

Synchronization content includes: page push synchronization function, synchronous browsing function, multi-frame synchronization, new window or multi-window synchronization, synchronization operation function, local directory browsing synchronization, sending email click synchronization, FTP synchronization based on HTTP, window closing synchronization, end Web page synchronization, even synchronization of internal elements or objects of the web page, in which when the synchronization window is closed, the other party will be prompted whether to perform the same closing operation, and when the web page synchronization is ended, it will be prompted whether to close all synchronization windows. The above methods are all generated by the synchronization window information received and sent, controlled and processed by the webpage synchronization control, and interpreted by the browser respectively, such as: HTTP synchronization means general web page synchronization, FTP synchronization means using the built-in FTP function of the browser, sending mail Click synchronization is the E-mail URL message to specify the browser to open the attached E-mail processing program, such as: Outlook Express and so on.

In addition to the above functions, the system also has web page synchronization control functions, namely: one-way synchronization or two-way synchronization, manual synchronization or automatic synchronization, and the combination of the two types of synchronization methods. The selection process of the synchronization method control function is shown in Figure 10. .

Among them, one-way synchronization means that the synchronization action is one-way, one side operates, the other side changes synchronously, and vice versa; two-way synchronization means that the synchronization action is two-way, one side operates, the other side changes synchronously, and vice versa; Manual synchronization refers to any operation in the browser, such as: browsing to other pages, the other party will not change accordingly, you must click a "push" button, then the content of the other party's window will be synchronously changed to the content of this page; automatic synchronization It means that any operation in the browser is regarded as a synchronous action, and the content of the other party is automatically synchronized with the content of the page.

All the generated synchronization windows can be in the synchronization active state at the same time, and correspond to each other's synchronization windows one by one, for example: No. 1 synchronization window corresponds to No. 1 synchronization window of the other party, and No. 2 synchronization window corresponds to No. 2 synchronization window of the other party, etc. etc. These windows can exist and be synchronized at the same time, and multiple synchronization windows of the same party will not interfere with each other.

The webpage synchronization of the present invention can cooperate with other calling media types, as: webpage synchronization can be combined with IP phone, text conversation, Web call back request call, after the call is set up, press the "escort browsing" button on the webpage, the other party will See the same page content. After that, the content of the web page will be synchronized until the "End Browsing" button is pressed. If the customer visits other webpages through the hyperlink of the webpage before being synchronized after initiating the call, the client's browser will first automatically return to the page when the call was initiated after synchronization.

When a webpage window for new webpage synchronization is assigned to a page synchronization thread, an event receiver corresponding to the webpage window will be created, and some actions performed in the webpage window will trigger corresponding events and be received by the event receiver Then call the corresponding event method in the page synchronization thread.

Main synchronous window event method among the present invention comprises:

1) The web page synchronization control synchronizes the window navigation pre-event method. This event corresponds to an action triggered before browsing a new webpage in the browser webpage window. That is: the event is triggered when the browser receives a new web browsing request. The specific processing is shown in Figure 7.

2) Web page synchronization control synchronization window navigation completion event method. This event corresponds to an action triggered when browsing a new webpage in the browser webpage window. That is, the event is triggered when the browser receives a new webpage browsing request and finds the website specified by the webpage address. The specific processing flow is shown in FIG. 8 .

3) The new browser window event method of the web page synchronization control. This event corresponds to the action triggered when the user browses a new web page with a browser and opens a new browser window. Its specific processing flow is shown in FIG. 9 .

4) Web page synchronization control synchronization window closing event method. This event corresponds to the action triggered when the browser webpage window is closed. After triggering, the window closing message is sent to the other party through the communication component, and then the corresponding synchronous window closing interface method is invoked by the other party's cooperation control unit. The process of closing the synchronization window called by the other party is shown in Figure 5.

Each processing flow of the present invention involves the sending of a page synchronization message of the webpage synchronization control, and the main flow of message processing is shown in FIG. 3 .

Web page synchronization A series of actions performed in the web page synchronization window of the browser triggers corresponding events, and at the same time, in order to make the other party's web page synchronization user's web page synchronization window perform the same action, it is necessary to send the action message of the web page to the other party. First, the synchronous window thread of web page synchronization sends the message to the "cooperative control unit" in Figure 1, and then the "cooperative control unit" forwards the message to the communication component, and the communication component transmits the message to the Web page through the web page synchronization message channel. The "communication application server" on the server is transmitted from the communication application server to the other party's communication component and "cooperative control unit", and the cooperative control unit calls the web page synchronization interface method, and finally sends the message to the corresponding synchronization window thread of the other party for processing. And call the synchronous action controller to perform the corresponding synchronous action.

For example, if the sent message is "transmitting external information and control messages", then interface methods such as synchronous window push interface method and synchronous window close interface method will be called. If the sent message is a message of "End Escorted Browsing", then the synchronization window end interface method of web page synchronization will be called.

Referring to FIG. 3 , FIG. 3 is a main flowchart of message processing of the web page synchronization control of the present invention. At the beginning of operation, the present invention first performs initialization processing of control variables, interfaces, events, etc., and creates multiple synchronization window event receivers and corresponding multiple synchronization window event processing threads. The number of synchronous window event processing threads can be defined flexibly. It is mainly responsible for monitoring the actions and events of the synchronization window, filtering out redundant window information, and then sending the synchronization information to the other user of the web page synchronization. The created synchronous window event receiver waits for the interface call of the external program or the event trigger message of the synchronous browser window action, and starts the corresponding synchronous window event processing thread for related processing. Different synchronization windows allocate different synchronization window event receivers and synchronization window event processing threads, so that actions in different windows are processed in different threads.

Referring to FIG. 4 , it is a flow chart of synchronization window push processing for web page synchronization in the present invention. The web page synchronization control synchronization window push interface method mainly includes: creating a user synchronization window, and connecting the created window with the corresponding synchronization window event receiver, so as to process a series of events generated by the browser in the synchronization event processing thread. Action, meanwhile, syncs this sync window to the specified URL.

When the user or server performs a push action, after the synchronization thread intercepts the action and event, it calls the synchronization window push interface of web page synchronization, which includes at least the following steps:

a. The system judges whether the exit message box and the close message box of the window exist? If it exists, first send a message to close the message box, and then go to step b; otherwise, go directly to step b.

b. Determine whether the synchronization window for pushing exists? If it does not exist, first create a new browser synchronization window, and then establish an event connection between the synchronization window and a synchronization window event receiver, and then proceed to step c; otherwise, directly proceed to step c.

c. Determine whether the push synchronization window is a frame sub-window? If yes, change the window synchronization address to be the main address, and then go to step d; otherwise, go to step d directly.

d. Call the browser interface to synchronize the synchronization window to the specified address.

This part is realized by the synchronous action controller of the page synchronization thread in the system structure shown in Figure 1, the page push synchronization, and the synchronous browsing function module.

Referring to FIG. 5 , it is a flow chart of the process of closing the interface of the synchronous window of the webpage synchronous control of the present invention. Synchronization window closing interface method of web page synchronization control The relevant processing is performed when the user synchronization window is closed. The relevant processing refers to: get the window number of the window to be closed, then call the process of closing the window, and set the close flag in the message box to true, and Disconnects from the corresponding sync window event sink and finally closes the sync window. But before closing the window, the system will ask the user and the server agent to confirm the closing? If it is, close it, otherwise, reset the close flag in the message box to be false, and restore the title of the corresponding browser window, but at this time the system just keeps the window and restores the window to a normal browser window instead of Control the window or react to events it generates. This part is realized by the synchronization action controller of the page synchronization thread and the window closing synchronization module in the system structure shown in Fig. 1 .

Referring to FIG. 6 , it is a processing flow chart of the method for ending the synchronization window of the webpage synchronization control of the present invention. The synchronization window end interface method of the webpage synchronization control is used to handle the related processing of the synchronization window when the webpage synchronization ends. The related processing includes: calling the end of the webpage synchronization process, and setting the flag in the end message box to true, and then closing all synchronization windows , and disconnects from all sync window event sinks. This method can ask the user and the server agent before the end of webpage synchronization, and can choose whether to close all windows or only disconnect the synchronization window event to keep the original window. This part is realized by the synchronization action controller of the page synchronization thread and the end page synchronization module in the system structure shown in Fig. 1 .

Referring to FIG. 7 , it is a flow chart of the method for processing the pre-navigation event of the synchronization window of the webpage synchronization control of the present invention. The pre-navigation event method of the synchronization window of the web page synchronization control is used for key processes such as intercepting and sending synchronous information of web page synchronization, web page echo control, multi-frame processing, and synchronization mode control. The processing flow includes at least the following steps:

a. When the pre-navigation event is triggered, first record the current URL and the current frame address, and then determine whether the current URL is the main frame? If yes, save the main frame variable, and then go to step b; otherwise, go directly to step b.

b. Determine whether the current frame address is an echo address? If yes, set the echo address flag to FALSE, and then go to step e; otherwise, go to step c.

c. Determine whether the trigger event is a main page or a single frame request? If yes, intercept its URL and notify the external program, and then go to step d; otherwise, go directly to step d.

d. Determine whether it is a frame address and has a frame record? If so, set the frame sending flag and go to step e; otherwise, go to step e directly.

e. Increment the count of event entries by one.

This part is realized by the browser window capture, synchronization window filter and multi-frame web page capture modules of the page synchronization thread in the system structure shown in Figure 1.

Referring to FIG. 8 , it is a flow chart of the method for processing the synchronization window navigation completion event of the webpage synchronization control of the present invention. The synchronization window navigation completion event method of the web page synchronization control is used for key processes such as intercepting and sending synchronization information of the new synchronization window, and subframe processing. The processing flow includes at least the following steps:

a. When the navigation completion event is triggered, first clear the event entry count, and then determine whether it is the corresponding main window? If yes, save the main frame variable, and then go to step b; otherwise, go directly to step b.

b. Set the browser window title; judge the URL sending flag, if the flag is true, then get the current URL address and send it to the server, and forward it to the other party's webpage synchronization control, and then enter step c; otherwise, directly enter step c.

c. Determine the URL sending flag of the subframe, if the flag is true, call the method of synchronizing the URL of the subframe, otherwise end.

This part is realized by the synchronization information sending module of the page synchronization thread in the system structure shown in Figure 1 .

Referring to FIG. 9 , it is a flow chart of processing the new browser window event method of the webpage synchronization control of the present invention. The new browser window event method of the webpage synchronization control is used for key processing such as intercepting the action of the new synchronization window, allocating the synchronization window thread, searching for the new window and invoking the synchronization information interception.

When a new window is opened, this event is triggered for processing, and synchronizes whether the window count exceeds the maximum window number limit. If so, the system will prompt the user "Too many open windows, cancel this new window". If not, allocate a synchronous event processing window number, which corresponds to an idle synchronous window event processing thread; then set the timer to call the callback process FindNotifyProc regularly to complete the event processing. The timer calls the "find new synchronization window method" belonging to the previously newly allocated synchronization window event processing thread in the background. At this time, this segment of the program has been running in the new thread, and its flow is shown in Figure 11. After finding the new window, connect the new window with the synchronous window event processing thread, and set the thread as the synchronous event receiver of the new window at the same time.

The part described in FIG. 9 is realized by the new window interception module of the page synchronization thread in the system structure shown in FIG. 1 .

Referring to FIG. 11 , it is a processing flowchart of the method for finding a new synchronization window for the web page synchronization control of the present invention. The method of finding a new synchronization window for the webpage synchronization control is used for key processes such as dynamically searching for a new synchronization window, intercepting synchronization information, and creating a synchronization event receiver corresponding to the new window. Before finding a new window, set the timer and search counter first; when a new window is found, set the synchronization window as this window, create a corresponding synchronization event receiver, and send the URL address of the current window to the server and the other party Web synchronization control. If the URL value of the current window is empty, first set the URL sending flag to true, and then send it.

This part is realized by the multi-window call interception processor module in the system structure shown in Fig. 1 .

Referring to FIG. 10 , it is a flow chart of the synchronous method control processing of the webpage synchronous control of the present invention. Synchronization mode control mainly uses sending or receiving synchronization mode control messages to set different direction attributes and operation modes respectively, and the webpage synchronization control or external program determines the direction of webpage synchronization according to different direction attributes. Including: one-way synchronization, two-way synchronization and manual/automatic synchronization.

Among them, one-way synchronization can only receive or only send; two-way synchronization can receive or send; and manual synchronization is determined by user operations. In the manual synchronization state, the actions generated by the user when operating the browser synchronization window are not sent to the other party, and only when the "Push" button is actively clicked will the synchronization information be sent to the other party. In the automatic synchronization state, the actions generated by the user when operating the browser synchronization window are automatically intercepted by the control and the synchronization information is sent to the other party.

This part is realized by the synchronization mode controller module of the page synchronization thread in the system structure shown in Fig. 1 .
