request and response objects are provided to work with them.
- The request data takes the environ object and allows you to access the data from that environ in a nice manner.
- The response object is a WSGI application in itself and provides a much nicer way to create responses.
Example
- 1 - the Hello World with response object
from werkzeug.wrappers import Response
def application(environ, start_response):
response = Response('Hello World!', mimetype='text/plain')
return response(environ, start_response)
- 2 - the Hello World with response object and request object that parses the URL to get the query string 'name'
from werkzeug.wrappers import Request, Response
def application(environ, start_response):
request = Request(environ)
text = 'Hello %s!' % request.args.get('name', 'World')
response = Response(text, mimetype='text/plain')
return response(environ, start_response)
- 3 - from the start page
from werkzeug.wrappers import Request, Response
@Request.application
def application(request):
return Response('Hello World!')
if __name__ == '__main__':
from werkzeug.serving import run_simple
run_simple('localhost', 4000, application)
