[0031] The page adaptation method, device and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0032] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0033] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0034] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0035] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0037] At present, with the popularization of mobile smart devices, mobile office has become a trend. Enterprises develop mobile web pages, which can enable employees to work anytime and anywhere, improve office efficiency, and thus improve enterprise production efficiency.

[0038] Many of the existing corporate office systems are old systems for personal computers (PCs). Due to historical technical debt, it is difficult to adapt these systems to mobile terminals based on the source code. In addition, due to user usage habits and long-standing business logic, it is not suitable to redevelop a new system.

[0039] In the prior art, the commonly used PC-side adaptation to mobile-side solutions is mainly performed through the following two methods: A and B:

[0040] A. Transform the PC front-end code into a responsive page, and add media queries (@media) to the original Cascading Style Sheets (CSS), so that different styles can be displayed according to the screen width. In addition, by monitoring the size change (resize) event of the web page window (window), use javascript code to add, delete, and modify page elements. However, when facing the old office system in the enterprise, due to the outdated technology stack of the old system, new technologies cannot be used for responsive page transformation, and the old system code is too old to be suitable for direct modification.

[0041] B. Based on the original PC page, a new set of mobile pages is developed to connect to the backend interface. Specifically, a set of pure mobile technology stacks and user interface (UI) libraries can be used. The newly developed mobile page and the original PC page will use different uniform resource locators (URLs). It is necessary to determine the type of user device in the server (nginx) or the javascript of the page and jump to the URL corresponding to the device. However, when facing the old office system in the enterprise, it is difficult to migrate to a new set of pages because the old system pages contain a lot of complex business logic. In addition, because the old system is very old and there is no backend interface documentation, the newly developed mobile page is difficult to connect. Moreover, when the old system page sends changes, the new mobile front end must also be modified again, which is too much work.

[0042] In addition, since the old system has many unauthenticated interfaces with injection problems and is not suitable for exposure to the external network, there are security issues with the above methods A and B.

[0043] In order to solve the problem in the prior art that it is difficult to adapt a PC-side web page to a mobile-side web page, the present application provides a page adaptation method, which can receive a page access request from a mobile terminal through a proxy service, then obtain a Hypertext Markup Language (HTML) page from a PC terminal, and adjust the Document Object Model (DOM) structure and page content of the HTML page according to the screen information of the mobile terminal to generate a mobile-side style page, and finally modify the request address of the generated mobile-side page, and return the mobile-side page to the mobile terminal. Since the page access request from the mobile terminal is received through a proxy service, and then the HTML page is obtained from the PC terminal by the proxy service, the security of accessing the PC-side page through the external network is guaranteed; at the same time, when generating a mobile-side page, the DOM structure and page content of the original HTML page are adjusted to adapt to the screen size of the mobile terminal, and no modification is made to the source code, which reduces the difficulty of adapting the PC-side page to the mobile-side page.

[0044] like Figure 1 FIG. 1 is a flowchart of a page adaptation method provided in an embodiment of the present application, and the method includes the following steps S101 to S103:

[0045] S101. When receiving a page access request from a mobile terminal, the proxy service obtains an HTML page from a PC terminal.

[0046] In an embodiment of the present application, the above-mentioned page access request includes the screen information of the above-mentioned mobile terminal.

[0047] In an embodiment of the present application, the above page access request is sent by the mobile terminal in an external network environment.

[0048] Exemplarily, the page access request may be an asynchronous JavaScript and Extensible Markup Language (ajax) request.

[0049] In an embodiment of the present application, the above-mentioned proxy service is used to provide a mobile terminal style page corresponding to the PC terminal page for the mobile terminal.

[0050] Exemplarily, the mobile terminal may include a portable mobile device such as a smart phone or a smart tablet.

[0051] Exemplarily, the PC terminal may include a desktop computer, a laptop computer, and other devices.

[0052] In an embodiment of the present application, after receiving the ajax request from the mobile terminal, the proxy service can use jsoup to obtain the html page from the PC terminal.

[0053] For example, Figure 2 As shown, a proxy service can be built between the user and the old system. The user can send an ajax request to the proxy service through the mobile terminal to obtain the mobile terminal page. After receiving the ajax request, the proxy service sends an ajax request to the old system in the company's intranet to obtain the PC terminal page, and then returns the PC terminal page to the user after adaptation.

[0054] Example 1, such as Figure 3 The following is the obtained PC page. The page is divided into two sides, the left side is narrower and the right side is wider. The left side is the menu bar, including menu 1, menu 2, and menu 3; the right side is the main content, including the form element, which uses a table layout, including field 1, field 2, and field 3. Each line is a tr, each field name is wrapped in a th tag, and each input box is wrapped in a td tag; there is a submit button at the bottom.

[0055] It should be noted that the above form is used to create the overall form in the HTML page and submit the form data to the server. The above tr is used to indicate a row in the HTML page. A tr contains one or more th or td elements.

[0056] S102: According to the screen information of the mobile terminal, the DOM structure and page content of the HTML page are adjusted to generate a mobile terminal page.

[0057] In the embodiment of the present application, the above-mentioned DOM structure is the architectural model of each frame in the above-mentioned HTML page.

[0058] Exemplarily, the above DOM structure may be the position of each paragraph, table, and input box in an HTML page.

[0059] In the embodiment of the present application, the above-mentioned page content may be the filling content in each frame in the above-mentioned html page.

[0060] Exemplarily, the above page content may be text, pictures, videos, etc.

[0061] Further optionally, in the embodiment of the present application, the above screen information includes screen size and screen resolution, and the above step S102 of "adjusting the DOM structure and page content of the HTML page according to the screen information of the mobile terminal" may include the following steps S102a and S102b:

[0062] S102a: modify or add or delete DOM elements of the HTML page according to the screen size.

[0063] In the embodiment of the present application, the above-mentioned screen size may be the size of the display area of ​​the mobile terminal screen.

[0064] Exemplarily, the screen size may be 6.0 inches, 6.2 inches, 6.5 inches, etc.

[0065] Exemplarily, the above DOM elements may include paragraphs, tables, input boxes, etc.

[0066] In the embodiment of the present application, DOM elements can be removed, modified, and newly added to adjust the DOM structure of the HTML page to make it suitable for the mobile terminal.

[0067] S102b. Modify or add or delete the style of the DOM element according to the screen resolution.

[0068] Exemplarily, the screen resolution may be 1280×720, 1920×1080, 2560×1440, etc.

[0069] Exemplarily, the style of the DOM element may include the style and class attributes of the DOM element and the style tag.

[0070] Example 2, combined with Figure 3 ,like Figure 4 The following is the adapted mobile page. Figure 3 The left menu bar is changed to Figure 4 The bottom navigation bar in the figure is added, and a flexible box (flex) layout is used. The font style is modified by modifying the style tag to change the PC page to the mobile style (for example, there is only one field in a row). Then, the style and class styles in the form, table, tr, th, and td tags are deleted (for example, the th width is modified to 1 / 4 and the td width is modified to 3 / 4), thereby obtaining the mobile page.

[0071] It should be noted that the above flex layout is a wrap layout, that is, Figure 4 The input box can be entered in a new line.

[0072] In this way, by adding, modifying, deleting and other operations on the elements and styles in the old system page, the PC page can be adapted without modifying the source code, reducing the difficulty of adaptation.

[0073] S103: modify the request address of the mobile terminal page, and send the mobile terminal page to the mobile terminal through the proxy service.

[0074] In the embodiment of the present application, the modified request address is the address of the proxy service.

[0075] Example 3, combined with Example 2, after adjusting the HTML page, you can also get the action attribute on the form tag (that is, the original request address) and modify it to the address of the proxy service.

[0076] It should be noted that the above action is used to instruct to submit the above mobile page to a specific address.

[0077] The following is an explanation of the agency services involved in this application:

[0078] In the embodiment of the present application, the above proxy service includes the following three functions P1 to P3:

[0079] P1. You can get the HTML page from the old system, adapt the HTML page to a mobile page, and return it to the user.

[0080] It should be noted that the above adaptation process is developed using the responsibility chain model. The specific adaptation steps include removing, modifying, and adding DOM elements and CSS styles, introducing new javascript and CSS files, modifying the ajax request path in the javascript code, setting cache, etc.

[0081] P2. Forwarding ajax requests in the page. The ajax requests initiated by js code in the mobile page to call the old system interface need to be accessed through the proxy service.

[0082] P3. Verify and authenticate access requests to the external network, and inject and intercept them to ensure the security of the old system interface on the company's intranet.

[0083] In the embodiments of the present application, Figure 5 The figure shows the architecture details of the above proxy service. The architecture is divided into three layers: interface layer, business service layer, and infrastructure layer.

[0084] It should be noted that the above proxy service is developed using the Java language and the Spring Boot framework.

[0085] Exemplarily, the above interface layer mainly includes two interfaces: an interface for obtaining mobile HTML pages and an interface for forwarding Ajax requests.

[0086] It should be noted that the above interface layer can call the business service layer or the infrastructure layer.

[0087] Exemplarily, the business service layer mainly includes a page adaptation processing module. This module uses the responsibility chain design pattern. After receiving a page request, it uses Jsoup to obtain the PC page from the old system, and triggers the logic of each node in the pipeline in turn, thereby converting a PC page into a mobile page step by step.

[0088] For example, taking the page A pipeline as an example, when the page A request is received, the code logic of the "page A processing node 1", "general processing node 1", "general processing node 2", and "page AB processing node" nodes will be triggered in sequence, and finally the mobile page of page A will be generated.

[0089] It should be noted that different page requests will go through different pipelines, and different pipelines may have the same processing nodes. Using the Inversion of Control (IOC) feature of the Spring framework, these processing nodes are registered in the container and configured as multi-instance beans. Then, a pipeline of a one-way linked list data structure of processing node beans is constructed using a postprocessor, and then the pipeline is registered in the container for the interface layer to call.

[0090] Exemplarily, the infrastructure layer mainly includes a cache module, an old system module, and a security module. The cache module is implemented using Redis, which can cache the mobile pages generated by the pipeline. When there is a page request, there is no need to perform the pipeline logic again, which can improve the response speed. The old system module can encapsulate the code for calling the old system interface, including methods for obtaining each page and forwarding ajax requests in the page. The security module can verify and authenticate the interface of the proxy service, prevent cross-site scripting (XSS) injection, and ensure the security of accessing the intranet system from the external network.

[0091] In the page adaptation method provided in the embodiment of the present application, the page access request of the mobile terminal can be received through the proxy service, and then the html page can be obtained from the PC terminal, and the DOM structure and page content of the html page can be adjusted according to the screen information of the mobile terminal to generate a mobile terminal style page. Finally, the request address of the generated mobile terminal page is modified, and the mobile terminal page is returned to the mobile terminal. Since the page access request of the mobile terminal is received through the proxy service, and the html page is obtained from the PC terminal by the proxy service, the security of accessing the PC terminal page through the external network is guaranteed; at the same time, when generating the mobile terminal page, the DOM structure and page content of the original html page are adjusted to adapt to the screen size of the mobile terminal, and no modification is made to the source code, which reduces the difficulty of adapting the PC terminal page to the mobile terminal page.

[0092] Optionally, in the embodiment of the present application, before “generating a mobile terminal page” in the above step S102, the page adaptation method provided in the embodiment of the present application may further include the following steps S102c and S102d:

[0093] S102c. Add the mobile CSS file and the mobile CSS file on the server.

[0094] In the embodiment of the present application, the server is a server of the HTML page. The server can send the HTML page to any networked user for viewing.

[0095] Example 4, combined with Example 2, after adjusting the HTML page, you can also introduce the newly created mobile.css (that is, the above-mentioned mobile CSS file) and the open source mobile adaptation tool flexible.js (that is, the above-mentioned mobile CSS file) in the head tag.

[0096] It should be noted that the above head is used to indicate the direction in which the browser requests the HTML page.

[0097] S102d. In the adjusted HTML page, add a first page identifier corresponding to the CSS file and a second page identifier corresponding to the javascript code.

[0098] In the embodiment of the present application, the first page logo and the second page logo are both logos that the user can click on the mobile page.

[0099] Exemplarily, the first page identifier may be generated by a link tag.

[0100] Exemplarily, the second page identifier may be generated by a script tag.

[0101] In an embodiment of the present application, CSS and javascript resources can be added on the server, and script or link tags that reference these resources can be added to the html page.

[0102] Further optionally, in the embodiment of the present application, in combination with the above step S102c, the "modifying the request address of the mobile terminal page" in the above step S103 may include the following steps S103a and S103b:

[0103] S103a. Use a regular expression to modify the request path of the javascript code in the mobile page.

[0104] In an embodiment of the present application, after adjusting the HTML page, a regular expression can be used to modify the path of the ajax request of the JavaScript code in the page.

[0105] S103b. Modify the domain name of the request path.

[0106] In the embodiment of the present application, the domain name can be modified by adding a prefix, so that the ajax request sent by the mobile terminal is sent to the proxy service, and then the proxy service requests the html page in the old system.

[0107] In this way, by modifying the request address of the mobile terminal page, the page access request sent by the mobile terminal first passes through the proxy service, and then the proxy service returns the page to the mobile terminal, thereby ensuring the security of page access.

[0108] Optionally, in an embodiment of the present application, the page access request further includes the account information and URL parameters of the mobile terminal. Before "sending the mobile terminal page to the mobile terminal through the proxy service" in the above step S103, the page adaptation method provided in the embodiment of the present application may further include the following steps S103c and S103d:

[0109] S103c, storing the mobile terminal page in cache.

[0110] In an embodiment of the present application, the account information of the above-mentioned mobile terminal may include account number, account type, account authority, etc.

[0111] In an embodiment of the present application, the above-mentioned url parameter is used to indicate whether the above-mentioned account information is known account information.

[0112] Exemplarily, the cache may be a redis cache.

[0113] S103d. Perform security verification on the mobile page based on the account information and URL parameters.

[0114] In an embodiment of the present application, it is possible to verify whether the current account information is the legitimate access account information for the above-mentioned mobile page based on the current account information and URL parameters in the received page access request.

[0115] Exemplarily, the generated mobile page can be stored in the redis cache, and the URL can be used as a key to directly access the mobile page.

[0116] In this way, by storing the generated mobile page in the cache, when the mobile terminal accesses the mobile page again, it first queries whether there is a corresponding mobile page in the cache. If so, the page can be sent directly to the mobile terminal, thereby improving the response speed; and, a security check is performed on the mobile page, further ensuring the security of the mobile terminal accessing the page through the external network.

[0117] Optionally, in the embodiment of the present application, Figure 6As shown, it is a flowchart of the proxy service pipeline corresponding to the page adaptation method provided in the embodiment of the present application, and the flowchart may include the following steps S1 to S10:

[0118] S1. Receive a mobile page request.

[0119] Exemplarily, the above page request includes the URL of the old system page and is used for request context.

[0120] S2. According to the URL of the page request, determine whether there is a cached page. If so, return the cached page as the mobile page.

[0121] S3. Use jsoup to obtain the PC-side HTML page from the old system.

[0122] S4. Remove, modify, and add DOM elements to adjust the DOM structure of the HTML page.

[0123] Exemplarily, the adjusted HTML page is adapted to the mobile screen.

[0124] S5. Remove, modify, or add new styles.

[0125] Exemplarily, the above style mainly refers to the style, class attributes and style tag on the above DOM element.

[0126] S6. Reference new javascript and CSS files.

[0127] Exemplarily, new javascript and CSS resources are added to the server, and new script or link tags referencing these resources are added to the HTML.

[0128] It should be noted that the above reference operation is completed in the general node.

[0129] S7. Modify the path in the javascript code on the page.

[0130] For example, a regular expression is used to modify the domain name of the path by adding a prefix, so that the above page request is sent to the proxy service, and then the proxy service requests the HTML page in the old system.

[0131] S8. Cache processed pages.

[0132] Exemplarily, after the above domain name is modified, the mobile page has been basically formed and can be stored in the cache.

[0133] S9. Process the page according to the request parameters.

[0134] Exemplarily, the mobile page may be processed again according to the request parameters.

[0135] It should be noted that the above request parameters include user, url parameters, etc.

[0136] S10. Return to the mobile page.

[0137] The embodiment of the present application can divide the page adaptation device into functional modules or functional units according to the above method example. For example, each functional module or functional unit can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules or functional units. Among them, the division of modules or units in the embodiment of the present application is schematic, which is only a logical function division.
