Description

Data update method, device, system and storage medium

This patent application claims priority from Chinese patent application filed on November 25, 2013, the application number is 201310603835.1, the applicant is Tencent Technology (Shanghai) Co., Ltd., and the invention name is "a data update method, device and system".

Background technique

In real-world application development, Hybrid App is an app between Native App and Web App, which is more easily accepted by developers. The Hybrid App is implemented by embedding a web container in the Native App to load and display web pages. The file composed of the loaded web page becomes a file on the web side. Native App can open the system and even the underlying interface to the Web page in an interface, so that the Web page has more capabilities. The Hybrid App looks the same as the Native App, but it combines the advantages of the Native App and the Web App. The overall features are closer to the Native App, and the Web App is quite different. Although its core has only one Web container, the Web page loaded by this container can use this container to interact with the local information, thus calling the underlying functions to implement complex functions and making up for the defects in Web App capabilities.

Hybrid App has more flexibility in web pages loaded through the web container, and it is easier to control the version update. However, due to the need for offline use of Hybrid App, most Hybrid App will store these Web-side files locally, and obtain a new version of the file through a channel, and store the new version of the file locally to complete the update process. One of them is to update the version by means of resource bundles. The resource package refers to a compressed package obtained by packaging the files on the web side.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments, The present invention is not limited by these specific embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the invention.

1 is a schematic flowchart of a data update method according to an embodiment of the present invention. The method in the embodiment of the present invention may be applied to a server, for example, an application server or a data server that can provide a data update service. Implement relevant data in the update side of a user terminal or other server The update, specifically, the method includes:

S101: After receiving the new version resource package, calculate a difference part between the new version resource package and each stored historical version resource package according to the difference algorithm, and use the difference part as the incremental difference package of each historical version resource package.

When the application developer has an update to the original application, the update of the related data in the update terminal may be implemented by the server releasing a new version of the resource package. The new version resource package includes a compressed package obtained by compressing each file data in the new version, for example, HTML (Hypertext Markup Language) corresponding data in the new version file, JS (JavaScript, A prototype-inherited object-oriented dynamic type client-side scripting language) is a compressed package obtained by compressing data, CSS (Cascading Style Sheet) corresponding data, and/or Image corresponding data.

In the embodiment of the present invention, after receiving the new version resource package uploaded by the developer or the new version resource package received by the other manner, the server receives the new version resource package according to a preset difference algorithm (such as a binary difference algorithm). The calculation process is performed on each historical version resource package of the local storage, and the calculated difference portion of each historical version resource package is used as an incremental difference package of each historical version resource package with respect to the new version resource package. The incremental difference packet includes a different part of the historical version resource package and the new version resource package, and the data amount thereof is significantly smaller than the data amount of the new version resource package. Specifically, the binary difference algorithm compares the binary of the two files, extracts the difference part and compresses it into a differential packet algorithm, and the specific implementation can refer to the open source component bsdiff (Binary diff utility). When the incremental differential package is merged with the old version resource package, the reference open source component bspatch (Binary patch utility, binary merge tool, corresponding to bsdiff) is used.

For example, the received version of the resource package is P, and the historical version resource package includes: the first version resource package A, the second version resource package B, and the third version resource package C. Three incremental differential packets: a first incremental differential packet ΔA with a first version of resource bundle A, a second incremental differential packet ΔB with a second version of resource B, and a third increase with a third version of resource bundle C The quantity difference packet ΔC. S102: Store each incremental differential packet, and record a mapping relationship between a packet identifier of each historical version resource bundle and a corresponding incremental differential packet storage address.

The calculated incremental differential packets may be stored in the CDN, and the storage address (Uniform Resource Locator) of each incremental differential packet in the CDN is determined. After storing the incremental differential packets corresponding to each historical version resource package, you can pass a resource mapping library or mapping table. The form stores the packet identifier of the historical version resource bundle and the mapping relationship for the incremental differential packet storage address. In the mapping relationship, the incremental difference packet corresponding to the storage address may update the resource package corresponding to the package identifier of the mapped historical version resource package. The packet identifier of each historical version resource package can be calculated by the MD5 (Message Digest Algorithm Fifth Edition) algorithm.

S103: If an update request carrying the resource pack identifier to be updated is received, determining a packet identifier of a historical version resource bundle that is the same as the identifier value of the to-be-updated version resource bundle identifier;

S104: Search for the incremental differential packet storage address according to the determined packet identifier, and return the found incremental differential packet storage address in response to the update request.

The update end may initiate an update request to the server by means of a timing update or a user manually triggering the update. The update end is connected to the corresponding server and the update request is sent by the prior art. The packet identifier of the resource package corresponding to the corresponding application file in the update end is carried in the update request, so that the server can determine the historical version of the resource package of the update end. Similarly, the method of calculating the packet identifier of the resource packet corresponding to the corresponding application file in the update end adopts the same calculation method as the packet identifier of the historical version resource package on the server side, and all of them are negotiated in the form of MD5 and the like. Calculation.

After receiving the update request of the update end, the server searches for the same historical version of the package identifier in the update request in the mapping relationship recorded in the S102 by using the packet identifier in the update request as a key. The packet identifier of the resource package, if the packet identifier of the same historical version resource bundle is found, the incremental differential packet storage address of the packet identifier mapping of the same historical version resource bundle is returned to the update terminal; The same historical version resource package indicates that the resource package of the update side is too old, and the new version resource package is directly returned to the update end.

When the server releases the new version resource package that updates the corresponding file of the target application, the embodiment of the present invention can obtain the incremental difference packet of the difference part between the new version resource package and each historical version resource package, and according to the mapping storage manner. When the user needs to update the corresponding file, the user can only send different parts to the update end, which reduces the amount of data required for the update, facilitates fast downloading, saves bandwidth resources and energy consumption, and saves user download time.

Referring to FIG. 2, it is a schematic flowchart of another data update method according to an embodiment of the present invention. The method in the embodiment of the present invention may be applied to an application server to implement update of application data and the like in the update terminal. On the basis of the foregoing embodiment, on the one hand, when the version information is carried in the update request, the version information of the update request and the version information of the new version resource package are added. The same judging operation is used to identify whether the update is required; on the other hand, in the resource mapping library, the package identifier of the historical version resource pack having the same identification value as the update resource pack identifier in the update request is not determined. Next, an operation of returning a new version of the resource package storage address to the update end is added to instruct the update terminal to download the complete new version resource package according to this, thereby improving the success rate of the data update; on the other hand, adding a new version is added. The package of the resource package is identified to the operation of the update end, so that the update end can perform update check according to this. Specifically, the method includes:

S201: After receiving the new version resource package, calculate a difference part between the new version resource package and the stored historical version resource package according to the difference algorithm, and use the difference part as the incremental difference package of each historical version resource package.

The difference algorithm may use the above-mentioned binary difference algorithm to calculate and process the new version resource package and the locally stored historical version resource package, and obtain the incremental difference package corresponding to each historical version resource package.

S202: Store each incremental differential packet, and determine a storage address of each incremental differential packet.

The incremental differential packets can be stored in a server such as a CDN, and the storage address of each incremental differential packet in a server such as a CDN can be determined.

S203: Add a delta differential packet storage address corresponding to the packet identifier of each historical version resource package in the preset resource mapping library including the packet identifier of each historical version resource package and the resource package storage address.

The resource mapping library is configured to store a mapping relationship between a package identifier of a resource package of each version of the target application and a resource packet storage address, so as to find a corresponding resource package according to the package identifier of the resource package. The package identifier of each historical version resource package can be calculated by the MD5 algorithm.

Further, in a case where the mapping relationship between the packet identifier and the resource packet storage address is stored, the storage address of the corresponding incremental differential packet is stored, so that the server can not only find the resource packet corresponding to the resource packet identifier, but also Can find the corresponding incremental differential package. Of course, it is also possible to save only the mapping relationship between the packet identifier of each historical version resource bundle and the corresponding incremental differential packet.

S204: Receive an update request sent by the update end, where the update request carries version information of the file to be updated in the update end and a version resource package identifier to be updated.

The update end may initiate an update request to the server by means of a timing update or a user manually triggering the update. The update end is connected to the corresponding server and the update request is sent by the prior art.

The update end obtains the version information of the file to be updated and the resource package identifier of the resource package to be updated corresponding to the resource package to be updated according to the file to be updated on the local end. The file to be updated is an application file to be updated on the local end of the update end.

In the update request, the update request includes not only the version resource package identifier to be updated, but also the historical version of the resource package of the update end, The version information of the file to be updated can be carried. The version information of the file to be updated is the version information corresponding to the file to be updated on the current update end. The version information can identify the current version status of the file to be updated.

In the embodiment of the present invention, the server first determines whether the file to be updated on the update end needs to be updated according to the version information of the file to be updated in the update request; if the update needs to be performed, the server receives the update according to the received information. The resource package identifier of the to-be-updated version determines the historical version of the resource package of the update end, so that it can further determine whether the update mode can adopt the incremental update mode according to the determined historical version.

Similarly, the method of calculating the packet identifier of the resource packet corresponding to the corresponding application file in the update terminal is the same as the method of calculating the packet identifier of the historical version resource package on the server side, and all of them are performed by using the identifier code calculation manner in the form of negotiation MD5 or the like. Calculation.

S205: Determine whether the version information in the update request is the same as the version information of the new version resource package.

Similarly, the version information in the update request may also be a version identification code (ie, a specific identifier value) obtained by the update end according to the MD5 algorithm for calculating the version number of the target application in the update end, and the version information of the new version resource package. The version identifier of the new version resource package obtained by the server according to the MD5 algorithm for calculating the version number of the new version may also be used. In the S205, the two version identification codes are compared. If the same, the version information in the update request is the same as the version information of the new version resource package, and the target application of the update end is already the latest version. If the two version identification codes are not the same, it indicates that the update terminal needs to perform subsequent update, and S206 described below is executed.

That is, in particular, before the S201, when a new version resource package is received, the version identifier of the new version resource package is added in a preset version mapping library including each historical version identifier and its corresponding version number. The mapping relationship with the new version number. The S205 may include: determining whether the version identification code in the update request is the same as the version identifier of the new version resource package recorded in the version mapping library; if not, determining the version information in the update request and the The version information of the new version of the resource bundle is different.

S206: If not, determine a packet identifier of the historical version resource package in the resource mapping library that is the same as the identifier value of the version resource resource identifier to be updated in the update request. If the packet identification of the same historical version resource bundle is determined, the following S207 is performed.

S207: Return, to the update end, an incremental differential packet storage address corresponding to a packet identifier of the same historical version resource package in the resource mapping library.

S208: If the packet identifier of the historical version resource package that is the same as the identifier value of the version resource resource identifier to be updated in the update request is not determined in the resource mapping library, the storage address of the new version resource package is Return to the update.

Searching, in the resource mapping library of the S203, the packet identifier of the historical version resource package that is the same as the packet identifier in the update request, by using the identifier value of the packet identifier in the update request, if the same history is found. Returning, by the package identifier of the version resource package, the incremental differential package storage address of the package identifier mapping of the same historical version resource package to the update terminal; if the same historical version resource package is not found, the new The storage address of the version resource bundle is directly returned to the update terminal.

The update end may initiate an HTTP download request to download a corresponding incremental differential packet or a new version resource bundle according to the incremental differential packet storage address returned by the server or the storage address of the new version resource package, to be used in the target application in the update terminal. Related files are updated.

S209: Generate a package identifier of the new version resource package, and return a package identifier of the new version resource package to the update end.

The S209 is an optional step. After returning the storage address of the incremental differential packet or the storage address of the new version resource package, the server may further calculate a packet identifier of the new version resource package by using an algorithm such as MD5, and The package identifier of the version resource package is sent to the update end, so that the update end verifies whether the update is successful according to the package identifier of the new version resource package returned by the server after updating the related file of the target application.

When the server releases the new version resource package that updates the corresponding file of the target application, the embodiment of the present invention can obtain the incremental difference packet of the difference part between the new version resource package and each historical version resource package, and according to the mapping storage manner. When the user needs to update the corresponding file, the user can only send different parts to the update end, which reduces the amount of data required for the update, facilitates fast downloading, saves bandwidth resources and energy consumption, and saves user download time. Moreover, marking the various resource packages and versions based on the identification code obtained by the identification code calculation method such as MD5 can ensure the validity and accuracy of downloading and updating the resource package, and ensure that the data update can be completed normally.

When the update end detects the timing or manually triggers, the update end calculates the packet identifier of the resource package corresponding to the file to be updated corresponding to the target application by using the MD5 algorithm.

The update end obtains the version information of the file to be updated and the resource package identifier of the resource package to be updated corresponding to the resource package to be updated according to the file to be updated on the local end. The version information in the update request may also be a version identification code obtained by the update end to the version number of the target application as calculated by the MD5 algorithm.

Which update resource packet is sent, that is, whether the incremental differential packet is sent to complete the data update in incremental differential manner, or whether a complete new version resource resource packet is sent to complete the data update in an alternate manner.

S303: Receive, according to the version information in the update request and the resource package storage address returned by the package identifier, initiate a download request according to the resource package storage address to obtain a resource package, and update the to-be-reserved according to the obtained resource package. Update file

The received resource packet storage address that is received includes an incremental differential packet storage address or a new version resource resource storage address. The incremental differential packet is a difference portion between the new version resource package corresponding to the file to be updated and the stored historical version resource package in the server according to the difference algorithm. Specifically, after receiving the update request of the update end, the server selects the corresponding resource package (incremental differential packet or new version resource package) according to the version information and the package identifier in the update request, and returns the storage address to the update terminal. 1 to FIG. 2 correspond to the description of the embodiment, and details are not described herein.

Wherein, the incremental differential packet is: the server calculates the pending according to the difference algorithm The new version resource package corresponding to the new file and the stored package identifier are the difference parts of the historical version resource package identified by the resource pack to be updated.

If the server does not determine the packet identifier of the historical version resource package that is the same as the identifier value of the version resource bundle identifier to be updated in the update request, the resource packet storage address received by the update terminal is the new version resource resource storage address. . The embodiment of the invention enables the update terminal to download only the different parts when updating the related files of the target application, thereby reducing the amount of data required for the update, facilitating fast downloading, saving bandwidth resources and energy consumption, and saving users. Download time.

A data processing system, comprising: a server and an update; wherein:

The server is configured to calculate, according to the difference algorithm, a difference part between the new version resource package and the stored historical version resource package according to the difference algorithm, and use the difference part as the incremental difference package of each historical version resource package. Storing each incremental differential packet, and recording the mapping relationship between the packet identifier of each historical version resource bundle and the corresponding incremental differential packet storage address;

The update end is configured to send an update request to the server, where the update request includes a version resource package identifier to be updated;

The server is further configured to: if receiving an update request that carries the resource pack identifier to be updated, determine a packet identifier of a historical version resource bundle that is the same as the identifier value of the to-be-updated version resource bundle identifier; Finding an incremental differential packet storage address and responding to the update request to return the found incremental differential packet storage address;

The update end is further configured to issue a download request according to the returned incremental differential packet storage address Load incremental packets to update the files to be updated.
A storage medium containing computer executable instructions for performing a data update method, when executed by a computer processor, characterized in that the method comprises the steps of:

After receiving the new version resource package, calculating a difference part between the new version resource package and the stored historical version resource package according to the difference algorithm, and using the difference part as the incremental difference package of each historical version resource package;

Storing each incremental differential packet, and recording a mapping relationship between a packet identifier of each historical version resource bundle and a corresponding incremental differential packet storage address;

And if the update request carrying the identifier of the resource pack to be updated is received, determining a packet identifier of the historical version resource package that is the same as the identifier value of the resource pack identifier to be updated;

The incremental differential packet storage address is looked up based on the determined packet identification and is responsive to the update request to return the found incremental differential packet storage address.
A storage medium containing computer executable instructions for performing a data update method, when executed by a computer processor, characterized in that the method comprises the steps of:

When the update of the file to be updated on the local end is detected, the resource package identifier of the to-be-updated version of the file to be updated is generated;

Sending an update request to the server, where the update request carries the version information of the file to be updated and the version resource package identifier to be updated;

Receiving, by the server, the downloading request according to the resource package storage address to obtain the resource package according to the version information in the update request and the resource package storage address returned by the package identifier, and updating the to-be-updated file according to the obtained resource package. ;

The received resource packet storage address includes an incremental differential packet storage address or a new version resource resource storage address, and the incremental differential packet is configured by the server to calculate the file to be updated in the server according to a difference algorithm. The new version of the resource bundle is stored with the differential portion of each historical version of the resource bundle.
