wsgiref.util.setup_testing_defaults(environ)
Update environ with trivial defaults for testing purposes.
This routine adds various parameters required for WSGI, including HTTP_HOST, SERVER_NAME, SERVER_PORT, REQUEST_METHOD, SCRIPT_NAME, PATH_INFO, and all of the PEP 3333-defined wsgi.* variables. It only supplies default values, and does not replace any existing settings for these variables.
This routine is intended to make it easier for unit tests of WSGI servers and applications to set up dummy environments. It should NOT be used by actual WSGI servers or applications, since the data is fake!
Example usage:
from wsgiref.util import setup_testing_defaults
from wsgiref.simple_server import make_server
# A relatively simple WSGI application. It's going to print out the
# environment dictionary after being updated by setup_testing_defaults
def simple_app(environ, start_response):
setup_testing_defaults(environ)
status = '200 OK'
headers = [('Content-type', 'text/plain; charset=utf-8')]
start_response(status, headers)
ret = [("%s: %s\n" % (key, value)).encode("utf-8")
for key, value in environ.items()]
return ret
httpd = make_server('', 8000, simple_app)
print("Serving on port 8000...")
httpd.serve_forever()
