a simple python server handles POST and GET request and have simple router function
for example, when you come in a request say GET /TestInterface/User/GetUserInfo you need to write a class in the project folder following the request path TestInterface.User.GetUserInfo and have a method called do_GET() where you should return the result for this request in bytes data. The POST request acts the same way but use do_POST() method.
whatever error, the server will return 404
