The environment dictionary is populated by the server with CGI like variables at each request from the client.
This script will output the whole dictionary:
#! /usr/bin/env python # Python's bundled WSGI server from wsgiref.simple_server import make_server def application (environ, start_response): # Sorting and stringifying the environment key, value pairs response_body = [ '%s: %s' % (key, value) for key, value in sorted(environ.items()) ] response_body = '\n'.join(response_body) status = '200 OK' response_headers = [ ('Content-Type', 'text/plain'), ('Content-Length', str(len(response_body))) ] start_response(status, response_headers) return [response_body] # Instantiate the server httpd = make_server ( 'localhost', # The host name 8051, # A port number where to wait for the request application # The application object name, in this case a function ) # Wait for a single request, serve it and quit httpd.handle_request()
To run this script save it as, say,
environment.py, open the terminal, navigate to the directory where it was saved and type
python environment.py at the command line. The server will be listening at http://localhost:8051
If in Windows it is necessary first to add the path to
python.exe to the system environment
Path variable. By the way if you can use Linux in instead of Windows do it. It will save some pain.
