Python version of socket communication simulation HTTP service

For more information, see the code. Compile a socket-Based C/S structure program in Python. Then, both parties can simulate HTTP Communication and directly access the server through a browser.

The server performs a simple analysis on the request content. if the request meets the HTTP format, the request is prompted as an HTTP request and a string in the HTTP format is returned. All threads are short connections and end with one answer, it can be said that it simulates the HTTP request method.
