Description

Technical Field

[0001] The present invention relates to the field of reading picture frameworks of mobile phone systems, and particularly to a picture reading method for displaying mobile phone system pictures on H5. Background Art

[0002] When users use a mobile banking app to operate business functions such as material management, contract management, document management, adding attachments, and editing products on an H5 page and upload pictures, it is crucial that the H5 page can promptly display the selected mobile phone system pictures after uploading. On mobile devices, especially iOS system devices, due to security restrictions and privacy protection, it may not be possible to directly access system pictures, which limits access to the file system. Enabling users to view the pictures they upload, facilitating users to delete or add new pictures at any time, meeting users' personalized needs for picture management, making users more convenient and efficient during use, and making users' operations more handy.

[0003] When processing a large number of or large files, it may have a certain impact on the performance of the device. Especially on devices with limited resources, it may lead to performance degradation or resource exhaustion.

[0038] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] H5 display of mobile system pictures based on ZZLGCDWebServer means that when the app starts, ZZLGCDWebServer is initialized. First, a singleton class ZZLGCDWebServerTool is created, the webServer is configured, the handler path of the request is added as the root path, the web server directory is set to the temporary folder path / temp, and all sub-folder paths under the temporary folder are allowed to be traversed. Implement the web server method to start ZZLGCDWebServer, the web server method to pause ZZLGCDWebServer, and implement the ZZLGCDWebServer proxy method. Use the subclass ZZLGCDWebServerMultiPartFormRequest of ZZLGCDWebServerDataRequest: to parse the body data when the Content-Type is multipart / form-data. Use the subclass ZZLGCDWebServerFileResponse of ZZLGCDWebServerResponse: to use the file content as the response information. As Figure 1 shown

[0040] 1. Use the -(BOOL)startWithPort:bonjourName: method of ZZLGCDWebServer to start the web service, passing 80 for port and nil for Name.

[0041] 2. Use the _stop method of ZZLGCDWebServer to pause the web service.

[0042] 3. Use the proxy methods webServerDidStart: and webServerDidStop: of ZZLGCDWebServer to listen for whether the web service has been started or paused successfully.

[0043] 4. Use the _start: method of ZZLGCDWebServer to obtain the listening port of the externally configured server and determine the form of accessing the server. Set the maximum number of connections in the waiting connection queue, create a listen socket, and start listening to the listen socket. As Figure 2 shown

[0044] 5. Create a method for the source that listens to the listen socket, a listen source for whether there is readable content (i.e., whether there is a client connection request).

[0045] 6. After the source monitors an event, it establishes a connection with the client. The socket generated here is called: connectsocket. If the connection is successfully established, the address information of the connector is obtained.

[0046] 7. Process the request, read the header, and use the dispatch_read method of ZZLGCDWebServer to read the data.

[0047] 8. Process the request, read the body data, and use different subclasses of ZZLGCDWebServerRequest to process the body data of different requests to conveniently format or store the body data.

[0048] 9. ZZLGCDWebServerDataRequest: Saves the body data in the form of the original data and provides convenient properties such as text and jsonObject to obtain the decoded body data.

[0049] 10. After obtaining an instance of ZZLGCDWebServerRequest externally, return an instance of ZZLGCDWebServerResponse. Construct the response information by passing in the original Data, and use ZZLGCDWebServerFileResponse to use the file content as the response information.

[0050] 11. Use the autorelease pool to automatically manage the generated connect socket and recycle the repeatedly generated connect sockets to avoid excessive memory consumption and occupying the mobile phone's running memory.

[0051] 12. Set the SO_NOSIGPIPE option to prevent the socket from emitting the SIG_PIPE signal and determine whether to re-establish the connection.

[0052] 13. The app writes the user-selected picture to the temporary folder path / temp and reads the picture by reading the content of the temporary folder path / temp.

[0053] Specific effects include:

[0054] Introducing the ZZLGCDWebServer framework provides flexible APIs that allow developers to customize routing and processing logic to adapt to different business scenarios.

[0055] Introducing the ZZLGCDWebServer framework can be compatible with different mobile phone models and different mobile phone system versions. Especially for iOS devices with security restrictions, it can be used normally.

[0056] Instant communication can be achieved through a local server, quickly responding to upload requests and accelerating the image processing speed.

[0057] Introduce the ZZLGCDWebServer framework to reduce the volume of AppDelegate.

[0058] ZZLGCDWebServer by default uses Apple's GCD (Grand Central Dispatch) to handle requests. This is a powerful framework for concurrent programming, providing functions such as thread management and task scheduling.

[0059] Enable the server to run efficiently on multi-core processors, ensuring the speed and stability of handling requests.

[0060] ZZLGCDWebServer supports the WebSocket protocol, allowing two-way real-time communication. It supports upload and download operations, making file management and data exchange simple.

[0061] Perform necessary processing on the uploaded image data on the server side, such as compression, cropping, format conversion, etc. operations to meet the specific requirements of the application.

[0062] Handle a large number of concurrent connections and have a low memory footprint.

[0063] Full-stack asynchronous design avoids performance degradation caused by blocking.

[0064] Beneficial effects:

[0065] A lightweight method for displaying mobile system images without other redundant code;

[0066] Handle a large number of concurrent connections and have a low memory footprint;

[0067] Full-stack asynchronous design avoids performance degradation caused by blocking.

[0068] The above specific implementation manners further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only the specific implementation manners of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
