Description

Technical Field

[0001] The present invention relates to the technical field of browser web page migration, and in particular to a cross-browser web page migration method and system. Background Art

[0002] With the popularization of the Internet, a large amount of information exists in the form of web pages. At present, most abnormal websites will design permission modules to allow different users to access different rights and interests information. Usually, it is manifested as various types of accounts, which are used to distinguish member rights and interests levels, functional roles, etc. The permission module allows users with different permissions to access different information, which is also a phenomenon of information isolation.

[0003] Accounts are usually used to log in and obtain permissions. The interactions in different applications vary, such as entering account passwords, SMS verification, code scanning, fingerprint, voiceprint, and face recognition, etc. In the Web field, browsers are windows for browsing web page information. To provide an interactive experience, Web engineers will use appropriate storage technologies to retain the permission data after logging in. This allows you to access permission pages without having to log in again when the browser is refreshed, restarted, or even when the computer is restarted.

[0004] At the relevant scene, the relevant staff immediately controlled the on-site personnel and equipment. It is often the case that the computer to be collected logs into the background but the account password cannot be asked. The time at the evidence collection site is relatively tight. If the amount of background data is huge, it will be a big challenge for evidence collection. How to extract web page permission data without an account, transfer permissions and authorize cross-browser access to web pages is an urgent problem to be solved in the evidence collection process. Due to the continuous updating of Web technology, there is currently no unified solution, and there are the following deficiencies in the market: 1. It is often believed that the permission environment is equivalent to the Cookie environment, and the incomplete environment leads to low compatibility. 2. Cookie settings are mostly single-domain, and when there is a reliance on third-party domains, there may be a lack of coverage and lead to failure. Summary of the invention

[0005] In order to solve the above technical problems existing in the prior art, the present invention proposes a cross-browser web page migration method and system to solve the above technical problems.

[0038] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] Figure 1 FIG. 1 shows a flow chart of a cross-browser web page migration method according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0041] S1: In the browser to be migrated, in response to having the permission to browse web pages, extract environmental data, serialize the environmental data and export the environmental file, the environmental data includes the environmental data of LocalStorage&SessionStorage, Cookie, IndexedDB storage technology data set.

[0042] In a specific embodiment, for Cookie data, the domain source set of the frames associated with all pages is obtained, a list of all cookies to be migrated from the browser is extracted, the cross-domain domain source set is derived from the domain field of the Cookie, and the global source set is merged to obtain the global source set. The global source set and all Cookies together constitute the environmental source data of the Cookie, which is serialized and persisted as an environment file.

[0043] In a specific embodiment, for LocalStorage & SessionStorage, Web DOM technology is used to inject the target web page environment through a plug-in to perform the extraction operation. The internal storage of LocalStorage & SessionStorage is a JSON object with a value type of string, which is directly serialized and persisted to obtain the environment file.

[0044] In a specific embodiment, for IndexedDB, the corresponding Web API operation is used to inject the target web page environment through a plug-in to perform the extraction operation. By enumerating all databases, tables in each database, and fields in the table, they are summarized and serialized according to the field type. If the field contains a CryptoKey object, the IndexedDB environment is manually copied.

[0045] S2: Import the environment file into the browser to be migrated, parse and deserialize the environment, set the environment, open it and allow users to browse the consistent web page.

[0046] In a specific embodiment, before S2, it also includes determining whether it is necessary to supplement the IndexedDB environment, and if necessary, copying the manually copied IndexedDB folder content to the consistency directory of the browser to be migrated.

[0047] In a specific embodiment, S2 specifically includes: deserializing and parsing the environment file, obtaining Cookie, LocalStorage&SessionStorage and IndexedDB environment data:

[0048] For the Cookie environment, enumerate all domain source links and each cookie, and in response to the domain source link matching the domain field of the Cookie object, perform association settings;

[0049] For LocalStorage & SessionStorage, inject a custom settings script when loading or refreshing the page, and set it through window.localStorage and window.sessionStorage respectively;

[0050] For IndexedDB, inject custom scripts into the page and use Web API operations to enumerate all database information. If it does not exist, create it. Then enumerate all tables in each database. If it does not exist, create it. Try to set the value of each field in each table and skip existing fields.

[0051] Continue to refer Figure 2 , Figure 2 A general flow chart of a cross-browser webpage migration method according to a specific embodiment of the present application is shown as follows: Figure 2 As shown, the general process of web page migration in this embodiment is as follows: in browser A, after ensuring the right to browse a certain web page, extract the environment data, serialize the environment data and export it into an environment file; then import the environment file into browser B, parse and deserialize the environment, set the environment, open and have the right to browse the consistent web page. Figure 1 As shown, the left side is the environment migration out and the right side is the environment migration in; the environment data includes data sets of three storage technologies: LocalStorage&SessionStorage, Cookie, and IndexedDB.

[0052] Figure 3 A flowchart of an environment migration of a specific embodiment of the present application is shown as follows: Figure 3 As shown, when extracting cookie data, it is necessary to obtain the domain source (or igin) set Set A of all frames associated with the page. The domain source consists of the protocol and the domain name. Then, after extracting all the cookie lists of the browser, the cross-domain domain source set Set B can also be derived from the domain field of some cookies. After merging, a global source set without duplication is formed. The global source set and all cookies become the environment source data of the cookie, which is serialized and persisted into an environment file.

[0053] LocalStorage & SessionStorage are mainly extracted using Web DOM technology. Plugin technology is required to inject the target web page environment to perform the extraction operation. Since the internal storage of Storage is a JSON object and the value type is a string, it can be directly serialized and persisted into an environment file.

[0054] IndexedDB mainly uses the corresponding Web API operations. First, it is necessary to use plug-in technology to inject it into the target web page environment to perform extraction operations. By enumerating all databases, all tables in each database, and all fields in each table, they are summarized and serialized according to the field type. For example, binary data can be serialized into a Base64 string. It is particularly important to note that if the field data contains a CryptoKey object, it cannot be serialized and the IndexedDB environment needs to be copied manually. The address may vary for different browsers. For Windows Chrome, it is as follows, where Default refers to the default user: C:\Users\xxx\AppData\Local\Google\Chrome\User Data\Default\IndexedDB.

[0055] Figure 4 A flowchart of an environment migration of a specific embodiment of the present application is shown as follows: Figure 4 As shown, before migration, you need to determine and supplement the IndexedDB environment. If necessary, copy the manually copied IndexedDB folder content into the browser consistency directory to be migrated;

[0056] After deserializing and parsing the environment file content, the environment data of Cookie, LocalStorage&SessionStorage and IndexedDB are obtained respectively;

[0057] To migrate the cookie environment, you must first enumerate all domain source links and each cookie. If the domain source link matches the domain field of the cookie object, try to associate it to ensure that all cookies in the entire domain chain are covered.

[0058] LocalStorage & SessionStorage are mainly set using Web DOM technology. After loading or refreshing the page, a custom setting script is injected and set using window.localStorage and window.sessionStorage respectively.

[0059] IndexedDB also needs to be executed by injecting a custom script into the page and using the Web API. Enumerate all database information, and create the corresponding database if it does not exist; enumerate all database tables in each database, and create the corresponding table if it does not exist, and try to set the value of each field in each table. If the field already exists, skip it without forcibly overwriting the value.

[0060] Figure 5a-5bA schematic diagram showing the effect of a cross-browser webpage migration method according to a specific embodiment of the present application is shown as follows: Figure 5a-5b As shown, in a browser of a host computer, the environment data of the QQ mailbox is extracted; after the environment data file is imported into the browser of the virtual machine environment by the above method of the present application, the browser can be accessed normally (such as Figure 5b ).

[0061] The present invention proposes a cross-browser web page migration method and system, which supports account-free extraction of web page permissions and rapid export of environmental data, imports into heterogeneous environment browsers and authorizes access to web pages. Relevant staff can extract environmental files of abnormal websites in the first place, transmit them to relevant evidence collection personnel for web page environment restoration, and simultaneously conduct remote inspection and evidence collection. This increases the use scenarios of remote inspection of web page electronic data and speeds up the work efficiency of relevant staff.
