Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a method for data synchronization according to an embodiment of the present invention, which can be used for various client devices, such as PCs (personal computers), smartphones, tablets, and the like. As shown in fig. 1, the method may include the following steps.
In step S110, a request is sent to the server apparatus, and an operation interface sent by the server apparatus in response to the request is received.
For example, when a synchronization-related web page is opened on a client device, the client device sends an http request to a server device. The server device extracts the operation interface and sends the operation interface to the client device.
In step S120, the received operation interface is presented.
The client device displays the received operation interface, for example, the operation interface as shown in fig. 2, in a display or a screen. The operation interface records the time of the last data synchronization and the starting date and the ending date of the last execution.
In addition, in another example, the execution condition of each time of synchronizing data, the synchronized IP, the port configuration, the fixed setting condition, and the like can also be checked in the operation interface.
In step S130, after receiving the input synchronization command from the operation interface, the client program is called.
For example, when a "synchronize" button in the operation interface is clicked, and a synchronization instruction is received from the operation interface, the client device may call the client program by using an object and a method built in the browser.
In this way, the operation interface can be obtained by accessing the server device, the client program is called by operating in the operation interface to send the synchronous data to the server device, and the server device carries out data synchronization.
In step S140, synchronized data is obtained from a variety of data sources by the client program.
In one embodiment, the obtaining of synchronized data from multiple data sources by the client program may include the client program obtaining multiple types of synchronized data from at least two of a database, an application program, and a file system using Java technology and/or C + + technology.
For example, the client program may obtain data of different data types and different data structures from different data sources such as a database, an application program (e.g., invoicing software), a file system, and the like through java or C + +. For example, the different types of structured data may include character-type, date-type, numerical-type, etc. data in a database, and the different types of unstructured data may include pictures, videos, text files, word documents, etc. in a file system.
Therefore, data of different data sources, data of different types and data of different structures can be synchronized, and the diversity of data synchronization is improved.
In step S150, the obtained synchronization data is encapsulated into a data packet, and the data packet is transmitted to the server apparatus for data synchronization.
For example, after the client program obtains the data, the client program transmits the data packet to the server device through network encryption, data encoding and encapsulation, and by establishing a socket link channel with the server device. After receiving the data packet, the server device decrypts and decodes the data packet, analyzes the data packet to obtain data, converts the data into a format for synchronization, and synchronizes the data after format conversion to a database or a file system or other application systems. The security of data transmission can be improved by encrypting through an encryption method.
By the technical scheme, complete synchronous data can be obtained, all data needing to be synchronized are synchronized into the system, and the diversity of data synchronization is improved.
In one embodiment, as shown in FIG. 3, the method may further include the following steps.
In step S302, an input synchronization condition is received from the operation interface.
In step S304, the received synchronization condition is encapsulated into a packet, which is transmitted to the server apparatus to save the synchronization condition.
For example, a user inputs a synchronization condition in an operation interface, and the client device transmits a data packet carrying the synchronization condition to the server device through network encryption, data encoding and encapsulation, and a socket link channel established with the server device. After receiving the data packet, the server equipment decrypts the data packet, analyzes the data packet to obtain a synchronization condition, stores the synchronization condition, and directly loads the maintained synchronization condition for data synchronization during synchronization.
Therefore, when the user synchronizes data, the server equipment can automatically load the synchronization condition, and the user does not need to input the synchronization condition every time, so that the use of the user is facilitated.
In one embodiment, as shown in fig. 4, the method may further include the following steps.
In step S402, the input log content item is received from the operation interface.
In step S404, the received log content item is packaged into a data packet, and the data packet is transmitted to the server apparatus.
In step S406, a synchronization log generated by the server device from the log content item is received.
In step S408, the received synchronization log is presented.
For example, a user may customize the synchronization log. The user inputs log content items such as an operator of the synchronization operation, operation time, elapsed time, execution result, failure reason, and the like through the operation interface. The client device passes the data packets carrying the log content items to the server device by network encryption, data encoding and encapsulation, and by establishing a socket link channel with the server device. And after receiving the data packet, the server equipment decrypts the data packet, and analyzes the data packet to obtain the log content item. The server device extracts relevant information from the log based on the log content item, generates a synchronization log using the relevant information, and sends the synchronization log to the client device. The client device receives the synchronization log and then performs presentation, and the presented synchronization log is as shown in fig. 5.
Therefore, the customized synchronous log can be provided according to the user requirement, and the use by the user is facilitated, so that the error positioning can be timely carried out when the abnormity occurs.
Fig. 6 is a flowchart of a method of data synchronization according to an embodiment of the present invention, which may be used for various server devices, such as an application server, a system server, and the like. As shown in fig. 6, the method may include the following steps.
In step S610, a request sent by the client device is received.
In step S620, in response to the request, the operation interface is extracted and sent to the client device.
In step S630, a data packet transmitted by the client device is received.
In step S640, the synchronization data is parsed from the data packet, the synchronization data is converted into a format for synchronization, and the format-converted synchronization data is synchronized into one or more systems.
For example, the client device sends an http request to the server device, and the server device receives the http request, extracts the operation interface in response to the http request, and sends the operation interface to the client device. And the user enables the client device to call the client program to send the synchronous data to the server device through the operation in the operation interface. For example, after the client program acquires the data, the client program transmits the data packet to the server device by network encryption, data encoding and encapsulation, and by establishing a socket link channel with the server device. And after receiving the data packet, the server equipment decrypts and decodes the data, and analyzes the data packet to obtain the data used for synchronization. The server device may perform format conversion on the data according to a correspondence between the set format and the system to be synchronized, so that the data after the format conversion is adapted to the system to be synchronized. The format-converted data is then synchronized to a corresponding system to be synchronized, such as a database or file system, or other application system.
The Netty open-source technology framework can be adopted, so that the plurality of client devices can be simultaneously transmitted to the server device, and the transmission efficiency is improved. Moreover, data can be encrypted and transmitted, and data security is enhanced.
In an embodiment, the method may further include parsing out the synchronization condition from the data packet, and storing the synchronization condition. Synchronizing the format-converted synchronization data to one or more systems may include loading the stored synchronization conditions, and synchronizing the format-converted synchronization data to one or more systems according to the synchronization conditions.
Therefore, when the user synchronizes data, the server equipment can automatically load the synchronization condition, and the user does not need to input the synchronization condition every time, so that the use of the user is facilitated.
In an embodiment, as shown in fig. 7, the method may further include the following steps.
In step S702, the log content item is parsed from the data packet.
In step S704, the corresponding log content information is called from the log content item, and a synchronization log is generated using the log content information.
In step S706, the synchronization log is transmitted to the client device.
Therefore, the customized synchronous log can be provided according to the user requirement, and the use by the user is facilitated, so that the error positioning can be timely carried out when the abnormity occurs.
FIG. 8 is a diagram of an exemplary scenario for data synchronization according to an embodiment of the present invention. The system for data synchronization comprises a client device and a server device, wherein the client device comprises a browser and a client program, and the client program can access a database, invoicing software and a file system in the client device. The client device and the server device establish connection through TCP/IP, and the server device can synchronize data of a file system, a database and other application systems of the system. As shown in fig. 9, the method in this embodiment may include the following steps.
In step S902, the browser of the client device transmits an http request to the server device. In step S904, the server device receives the http request, and extracts the operation interface. In step S906, the server device transmits the operation interface to the client device in response to the http request. In step S908, the client device receives the operation interface sent by the server device in response to the http request. In step S910, the browser of the client device presents the received operation interface, for example, the operation interface as shown in fig. 2. In step S912, when the "synchronize" button is clicked in the operation interface, a synchronization instruction is received from the operation interface, and the client device calls the client program using the object and method built in the browser. In step S914, the client program obtains a plurality of types of synchronization data from the database, the application program, and the file system using Java technology and/or C + + technology. In step S916, the client device receives the input synchronization condition from the operation interface. In step S918, the client device encapsulates the synchronization data and the synchronization condition encryption in a data packet, and transmits the data packet to the server device. In step S920, the server device receives the data packet sent by the client device, decrypts the data packet, and parses the synchronization data and the synchronization condition from the data packet. In step S922, the server device converts the synchronization data into a format used for synchronization, and synchronizes the format-converted synchronization data to a file system, a database, and other application systems in the system according to the synchronization condition. In step S924, the client device receives the input log content item from the operation interface. In step S926, the client apparatus encapsulates the received log content item into a data packet, and transmits the data packet to the server apparatus. In step S928, the server apparatus receives the data packet carrying the log content item, and parses the log content item from the data packet. In step S930, the server device calls corresponding log content information from the log content item, generates a synchronization log using the log content information, and transmits the synchronization log to the client device. In step S932, the client device receives the synchronization log generated by the server device from the log content item. In step S934, the browser of the client device renders the received synchronization log.
