Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a method and system for storing and loading a Web resource offline package. Background Art

[0002] In recent years, the mobile application market has flourished, especially the "traffic-level" apps, which have brought better experience to users. This is not only due to the functions of the apps themselves, but also due to the good interactive experience that the apps provide to users. In this context, Web offline loading technology has emerged, providing a new solution to the problem of loading H5 resources on mobile terminals, especially in the current H5+Native hybrid development model, Web offline loading technology plays an increasingly important role. The current Web offline loading technology mainly uses the following solutions to solve the problem of storage access security:

[0003] 1. Verify the signature: Before loading an offline package, verify its signature to ensure the integrity of the content and the reliability of the source. If the signature verification fails, the offline package will be rejected.

[0004] 2. Version check: Check whether the offline package version stored locally is consistent with the latest version on the server. If not, download the latest version from the server and replace the offline package stored locally.

[0005] 3. Load offline package: After verification, load the offline package file from local storage and parse its content for use by the H5 application.

[0006] The style of H5 pages is inconsistent with that of native pages, making debugging difficult and risking hijacking and inserting advertisements. Current Web offline loading technology uses technical means such as signature verification and version control to ensure the security and integrity of H5 offline resource compression packages during download and decompression, but there are still certain security risks. When the H5 offline resource package is decompressed, there is no security access measure for the resource file, especially the JavaScript file in the H5 resource file, which usually contains key code for interacting with the backend server. When the decompression path of the H5 offline resource package is leaked, the resource file is also easily hijacked, causing resource file leakage, which poses certain security risks. Summary of the invention

[0007] To address the deficiencies of the prior art, the present invention ensures the security of the code by encrypting the JavaScript file code in the Web offline resources and decrypting it when accessing it, thereby increasing the security of Web offline resource storage access to a certain extent and effectively preventing criminals from intruding into user information.

[0013] S4. Based on the mapping relationship table, the encrypted JavaScript file is queried and decrypted, and the JavaScript file is loaded and returned.

[0014] Furthermore, before obtaining the latest resource offline compressed package from the server and decompressing the latest resource offline compressed package to obtain the offline resource file, the method further includes:

[0020] If there is a JavaScript file in the offline resource file, traversing the JavaScript file set and loading the JavaScript file stream further includes:

[0021] Determine whether the size of the JavaScript file stream is greater than a preset threshold;

[0022] If the size of the JavaScript file stream is greater than the preset threshold, the preset threshold is used as the minimum unit, the JavaScript file stream is split based on the minimum unit and encrypted, and an encrypted JavaScript file is generated and stored;

[0023] If the size of the JavaScript file stream is not greater than the preset threshold, the JavaScript file stream is directly encrypted to generate and store an encrypted JavaScript file.

[0024] Furthermore, after maintaining the mapping relationship table between the name of the JavaScript file in the offline resource file and the encrypted JavaScript file, the method further comprises:

[0025] Delete the corresponding JavaScript file;

[0030] If the offline resource to be loaded is not a JavaScript file resource, the resource data is returned directly.

[0031] Furthermore, if the offline resource to be loaded is a JavaScript file resource, the corresponding encrypted JavaScript file is queried from the mapping relationship table and decrypted, including:

[0032] Determine the number of encrypted JavaScript files;

[0033] When the encrypted JavaScript file is a single one, the encrypted JavaScript file is directly decrypted and the JavaScript file data is returned;

[0034] When there are multiple encrypted JavaScript files, the thread pool is started to call multiple threads to decrypt the encrypted JavaScript files, assemble them into original JavaScript files, and return JavaScript file data.

[0051] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. It should be understood that the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments, and these embodiments are only used to illustrate the present application and are not used to limit the scope of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0052] like Figure 1 As shown, the embodiment of the present invention discloses a method for storing and loading a Web resource offline package, and the steps of the method include:

[0053] Step S1. Obtain the latest resource offline compressed package from the server, and decompress the latest resource offline compressed package to obtain an offline resource file.

[0054] In this embodiment, the offline resource file includes a JavaScript file, wherein the JavaScript file is used to store key codes for interacting with the server.

[0055] When the APP is started, it requests the latest offline resource compressed package list from the server, compares it with the local offline resource compressed package list, and updates the latest offline resource compressed package. When updating the offline package, it obtains the latest offline resource compressed package from the server, decompresses the compressed package, and generates an H5 offline resource file.

[0056] Step S2: Encrypt the JavaScript file in the offline resource file, generate an encrypted JavaScript file and store it.

[0057] Specifically, encrypting the JavaScript file in the offline resource file, generating and storing the encrypted JavaScript file, includes:

[0058] Determine whether there is a JavaScript file in the offline resource file;

[0059] If there is no JavaScript file in the offline resource file, directly delete the corresponding offline compressed package;

[0060] If there is a JavaScript file in the offline resource file, traverse the JavaScript file set and load the JavaScript file stream;

[0061] If there is a JavaScript file in the offline resource file, traversing the JavaScript file set and loading the JavaScript file stream further includes:

[0062] Determine whether the size of the JavaScript file stream is greater than a preset threshold;

[0063] If the size of the JavaScript file stream is greater than the preset threshold, the preset threshold is used as the minimum unit, the JavaScript file stream is split based on the minimum unit and encrypted, and an encrypted JavaScript file is generated and stored;

[0064] If the size of the JavaScript file stream is not greater than the preset threshold, the JavaScript file stream is directly encrypted to generate and store an encrypted JavaScript file.

[0065] In this embodiment, when there is a JavaScript file resource, the JavaScript file set is traversed, and the JavaScript file stream is loaded respectively to determine whether the JavaScript file stream is larger than a preset threshold of 200kb. If it is larger than 200kb, the JavaScript file stream is split, and the JavaScript file stream is split every 200kb, and then the split JavaScript file stream is stored using symmetric encryption. If it is not larger than 200kb, the JavaScript file stream is directly stored using symmetric encryption.

[0066] In this embodiment, the preset threshold can be set according to resource conditions.

[0067] In this embodiment, the JavaScript file stream may also be encrypted in an asymmetric encryption manner.

[0068] Step S3: Maintain a mapping relationship table between the name of the JavaScript file in the offline resource file and the encrypted JavaScript file.

[0069] In this embodiment, after the encrypted JavaScript file is generated, a mapping relationship table between the name of the original JavaScript file and the encrypted JavaScript file is maintained, and the original JavaScript file is deleted after the operation is completed.

[0070] Furthermore, after traversing the JavaScript file set, the original offline compressed package is deleted.

[0071] Step S4: Based on the mapping relationship table, the encrypted JavaScript file is queried and decrypted, and the JavaScript file is loaded and returned.

[0072] When an APP application accesses a Web offline resource, before WebView loads the H5 offline resource, it determines whether the offline resource to be loaded is a JavaScript file resource:

[0073] If the offline resource to be loaded is not a JavaScript file resource, the resource data is returned directly;

[0074] If the offline resource to be loaded is a JavaScript file resource, the corresponding encrypted JavaScript file is searched from the maintained mapping relationship table;

[0075] Furthermore, when the encrypted JavaScript file is a single one, the encrypted JavaScript file is directly decrypted and the JavaScript file data is returned to WebView;

[0076] Furthermore, when there are multiple encrypted JavaScript files, the thread pool is started to call multiple threads to decrypt the encrypted JavaScript files. After the decryption is completed, they are assembled into the original JavaScript files and the JavaScript file data is returned to WebView.

[0077] In this embodiment, decryption may be performed using an asymmetric decryption method.

[0078] like Figure 2 As shown, the embodiment of the present invention discloses a Web resource offline package storage and loading system, the structure of which includes:

[0079] An acquisition module is used to acquire an offline compressed package of the latest resource from a server, and decompress the offline compressed package of the latest resource to obtain an offline resource file;

[0080] An encryption module, used to encrypt the JavaScript file in the offline resource file, generate an encrypted JavaScript file and store it;

[0081] A maintenance module, used to maintain a mapping relationship table between the name of the JavaScript file in the offline resource file and the encrypted JavaScript file;

[0082] The loading module is used to query the encrypted JavaScript file based on the mapping relationship table and decrypt it, and load and return the JavaScript file.

[0083] In the embodiment of the present invention, the user starts the App and updates the latest H5 resource offline compressed package. At this time, the client application will perform a series of operations such as decompression, determining whether the decompressed resource directory contains JavaScript files, traversing JavaScript files, loading JavaScript file streams, encrypting JavaScript file streams to generate encrypted JavaScript files, etc. When the user accesses the H5 offline resource, the WebView container determines whether the JavaScript file resource is loaded before loading the resource, and then goes through a series of actions such as enabling threads, decryption, loading resources, and rendering resources, and finally the client application presents the result to the user.

[0084] By using this system, the above-mentioned operation processing method can be executed and the corresponding technical effects can be achieved.
