I. Implementation principle

  1. HTTP requests are TCP communications, so the first step is to instantiate the QTcpServer class listening port and bind the newConnection signal slot.
  2. Once there is a new connection, it is handed over to a special unpacking class for processing, and the corresponding data is unpacked. If the HTTP request has a specific header data, such as whether it needs to be saved, it is taken out and the application is parsed.
  3. Sending and receiving data interaction is actually the interaction of the QTcpSocket communication object, but the sending and receiving data with the corresponding header data.
  4. To reply to web page data, simply send the HTML data of the web page to the requesting object.

Two, functional characteristics

  1. Support multiple client connections at the same time, 100 no pressure.
  2. You can set whether HTTP requests are long or short connections. The default is long connections.
  3. Supports multiple reply data formats, including web content, JSON data, and so on.
  4. The server example contains both file reply reading and database reply reading.
  5. Support 8 color schemes (dark, gray black, dark green, light yellow, dark blue, dark black, dark blue, default).
  6. The client can specify the request address, and the server can specify the network card and port to listen.
  7. All requests and connections are counted, and the IP and port numbers for all online requests are displayed in the table.
  8. Can provide a simple web page configuration service, including interaction, as the device web configuration.
  9. Can be expanded freely to add permission verification, etc., as an HTTP request server.
  10. Pure Qt implementation, code framework clean, annotation complete, support any Qt version, any compiler, any operating system.
