First, the concept of WSGI agreement
What the 1.WSGI protocol is:
WSGI (Web server gateway Interface): Python Web Server Gateways interface.
2. Function:
It's good to detach the Web framework from the Web server . This means that the server is only connected to the client, and the specific business logic code is done by the framework! So they can do their duties.
Second, define the Wsgi interface
The interface for defining WSGI is very simple, just implement a method in the framework to respond to HTTP requests! The specific implementation is as follows:
1 def application (environ, start_response): 2 Start_response (' kOK', [('content-type ' text/html '; ' Charset=utf-8 ')])3 return body
Environ: is a dictionary type of data sent from the server to the framework;
Start_response: is a function defined in the server, which is called in the framework;
The first parameter is an HTTP response status code;
The second parameter is the information for each field in the response body.
