[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Before describing the method of the present invention in detail, the terms involved in the present invention are first explained schematically.

[0025] Entity metadata: refers to data that describes an entity. Metadata is a description of the attributes, characteristics, or relationships of these entities and does not contain data about the entity itself. Metadata can be used to define and describe entities and their relationships in the database to help understand and manage data. Metadata can be used to better understand and query data, perform data correlation analysis, and optimize data processing flows. In addition, metadata is also used to define and describe the source, quality, and other data-related information of the data, which is critical to ensuring the accuracy and reliability of the data. In short, entity metadata is data that describes an entity. It does not contain the specific content of the entity, but provides information about the structure, attributes, relationships, etc. of the entity to help understand and manage data.

[0026] Service Worker: It is one of the core components of PWA (Progressive Web Application) technology. It is a script that runs independently of the web page in the background and can provide a variety of enhanced functions for web applications, such as offline support, push notifications, and cache management. It plays an important role in improving the performance of web applications and user experience.

[0027] Application Cache (AppCache) technology: Application Cache is a technology introduced in the HTML5 standard, which is designed to allow Web applications to be used when users are offline. Through application cache, developers can specify a set of resources that will be cached by the browser and loaded directly from the cache when the user is offline. Application cache uses manifest files to define which resources need to be cached and which resources can be obtained from the network.

[0028] LocalStorage and IndexedDB: These technologies provide client-side storage capabilities for Web applications. LocalStorage provides simple key-value pair storage, suitable for storing small amounts of data; while IndexedDB is a powerful NoSQL database suitable for storing more complex data structures and large-scale data.

[0029] Pure Service Worker and Cache API: Service Worker is a script that runs in the background of the browser and can intercept and process network requests to control cache and offline access. It is the mainstream technology for offline support of Web applications. Service Worker combined with Cache API can provide a more flexible and efficient cache management mechanism for Web applications.

[0030] PWA (Progressive Web Apps) technology: PWA is a web application built using modern web technologies. It provides a user experience close to native applications by combining technologies such as Service Worker and Web App Manifest. PWA applications can be used offline and can be installed on user devices like native applications.

[0031] Combine the following Figure 1-Figure 4 The present invention describes a metadata-based application offline management method and device.

[0032] It should be noted that existing technologies usually use Webview technology to develop apps. Compared with pure native apps, it has the following advantages: cross-platform, fast iteration and update, reduced development costs, flexibility and easy adjustment, shared code and resources, consistent user experience, lightweight development, and seamless integration. However, it also has several major disadvantages, as follows: 1. High network dependency: Traditional web applications usually require real-time network connection to access resources such as HTML, JS, CSS, and images. If the network connection is unstable or the user is offline, the application may not work properly or may be completely unavailable.

[0033] 2. Complex cache management: Although some web applications can use the browser's cache mechanism to store static resources, this method has limitations in controlling cache updates and cleanup. The browser's cache strategy is usually managed by the browser itself, and it is difficult for developers to implement refined cache control, which may result in the use of outdated resources or occupying too much storage space.

[0034] 3. Difficulty in data synchronization: For applications that require a large amount of entity metadata, it is usually necessary to frequently communicate with the server to keep the data up to date. This approach not only increases network traffic, but may also lead to poor user experience, especially in low-bandwidth or no-network environments.

[0035] 4. Limited offline usability: Most web applications cannot be used normally in offline environments, especially those that rely on dynamic data. This limits the availability and user experience of the application.

[0036] Based on this, the present invention provides an offline application management method based on metadata to solve at least one of the above problems.

[0037] Figure 1 is a flowchart of the metadata-based application offline management method provided by the present invention, such as Figure 1 As shown, applied to the client, the method includes the following: Step 100: When the client is in offline mode, if a resource request is detected, the resource request is intercepted by an interception tool.

[0038] Figure 2 This is a complete flow chart of the metadata-based application offline management method provided by the present invention. Figure 2 The metadata-based application offline management method provided by the present invention is described.

[0039] It should be noted that in order to achieve offline rendering of application pages, it is necessary to cache offline package data and static resources locally in advance in the client online mode. The following describes the caching methods of the two types of data respectively.

[0040] In one embodiment, in step 100, when the client is in offline mode, if a resource request is detected, before intercepting the resource request by an interception tool, the method further includes: When the client is in online mode, if a first preset trigger condition is met, an offline package acquisition request is sent to the server; wherein the first preset trigger condition includes: the application is loaded for the first time or the user actively triggers the offline package download; The receiving server sends an initial offline package based on the offline package acquisition request, downloads and decompresses the initial offline package, obtains the offline package, and stores the offline package in a local cache.

[0041] It should be noted that the offline package contains a large amount of entity metadata and configuration information.

[0042] Specifically, see Figure 2 , the configuration process of the offline package is: setting basic information of the offline package, adding entity objects, filters for entity data, and setting permissions for the offline package. In the online mode of the client, users can download and decompress the offline package, and can also automatically or manually submit entity data generated in the offline mode. During the first loading of the application, or when the user actively triggers the offline package download, the offline package module will download an offline package containing a large amount of entity metadata. After the download is complete, the data in the offline package will be stored in IndexedDB or other suitable local storage.

[0043] In another embodiment, in step 100, when the client is in offline mode, if a resource request is detected, before intercepting the resource request by an interception tool, the method further includes: When the client is in online mode, if a second preset trigger condition is met, registering and activating the interception tool; wherein the second preset trigger condition includes: the user accesses the application for the first time; The static resources of the application are stored in the local cache through the interception tool.

[0044] Specifically, when a user visits an application for the first time, the Service Worker will be registered and activated. After activation, the Service Worker will pre-cache the static resources of the application (such as HTML, CSS, JS, and images). These resources are stored locally through the Cache API. When the user visits again, the application will directly read these resources from the local cache without relying on the network.

[0045] Step 200: Obtain static resources and offline packages in the local cache based on the resource request, and render the application page offline based on the static resources and entity metadata in the offline package; wherein the offline package is obtained by the client requesting and downloading and decompressing the package in advance from the server in the online mode.

[0046] Specifically, in a network environment, limited network requests will be made and the data will be kept in local LocalStorage or IndexedDB to ensure the consistency of online and offline data.

[0047] Furthermore, when the application is running offline, all resource requests will be intercepted by the Service Worker and responded to based on the locally cached and stored data. Since static resources, entity metadata, and some interface data are cached or stored, the main functions of the application can run normally in an offline state.

[0048] The above is a description of the steps of the metadata-based offline application management method provided by the present invention. From the description of the above steps, it can be seen that the metadata-based offline application management method provided by the present invention is applied to the client, and when the client is in offline mode, if a resource request is detected, the resource request is intercepted by an interception tool; based on the resource request, the static resources and offline packages in the local cache are obtained, and the application page is rendered offline based on the static resources and the entity metadata in the offline package; wherein, the offline package is obtained by the client requesting and downloading and decompressing the server in advance in the online mode. It can be seen that the present invention greatly enhances the offline usage capability of Web applications by combining interception tools with offline package technology; static resources and a large amount of entity metadata can be pre-cached and stored to ensure that even when completely offline, the application can still provide complete functions and significantly improve the user experience.

[0049] Based on the above embodiment, in this embodiment, after step 200 obtains the static resources and offline packages in the local cache based on the resource request, and performs offline rendering on the application page based on the static resources and entity metadata in the offline package, the method further includes: Step 310: Store offline data generated when the application page is rendered offline in a local cache.

[0050] Step 320: when the client is in online mode and connected to the network, upload the offline data to the server; wherein the offline data includes: form data filled in by the user in offline mode and uploaded attachments.

[0051] Step 330: Obtain a verification result performed by the server based on the form data.

[0052] Step 340: When the verification result indicates that the verification has failed, a prompt message and a failure reason are generated, and the offline data is re-uploaded to the server based on the failure reason.

[0053] Specifically, see Figure 2 When the client is in online mode and connected to the network, the entity metadata generated offline is automatically or manually uploaded and verified by the server. If the verification is successful, a success prompt will be displayed; if the verification fails, a failure prompt will be displayed and the failure page will be jumped. Edit according to the reason for the failure and re-upload the offline data.

[0054] The metadata-based offline application management method provided in this embodiment ensures data consistency by uploading data during the offline period after reconnecting to the network.

[0055] The metadata-based offline application management method provided by the embodiment of the present invention greatly enhances the offline usage capability of Web applications through the combination of Service Worker and offline package technology. Static resources and a large amount of entity metadata can be pre-cached and stored to ensure that the application can still provide complete functions even when completely offline, significantly improving the user experience; an intelligent data synchronization and update mechanism is introduced, which can automatically download and update offline packages when there is a network by monitoring the update of server-side data, ensuring the consistency of local data and server data. Users can automatically obtain the latest data after restoring network connection, reducing the need for manual updates and optimizing the use of network traffic; by combining the use of Service Worker, offline packages and local cache technology, a relatively simple but powerful solution is provided, developers do not need to deal with complex synchronization logic or compatibility issues, greatly reducing the implementation and maintenance costs, and can be widely used in modern browsers that support Service Worker, and have stronger compatibility.
