Question

I am trying to catch POST data from a simple form.

This is the first time I am playing around with WSGIREF and I can’t seem to find the correct way to do this.

This is the form: <form action='test' method='POST'> <input type='text' name='name'> <input type='submit'></form> 

And the function that is obviously missing the right information to catch post:

def app(environ, start_response):     '''starts the response for the webserver'''     path = environ[ 'PATH_INFO']     method = environ['REQUEST_METHOD']     if method == 'POST':         if path.startswith('/test'):             start_response('200 OK',[('Content-type', 'text/html')])             return 'POST info would go here %s' % post_info     else:         start_response('200 OK', [('Content-type', 'text/html')])         return form() 

Answer 1

You should be reading responses from the server.

From nosklo’s answer to a similar problem: ‘PEP 333 says you must read environ[‘wsgi.input’].’

Tested code (adapted from this answer):
    Caveat: This code is for demonstrative purposes only.
    Warning: Try to avoid hard-coding paths or filenames.

def app(environ, start_response):     path    = environ['PATH_INFO']     method  = environ['REQUEST_METHOD']     if method == 'POST':         if path.startswith('/test'):             try:                 request_body_size = int(environ['CONTENT_LENGTH'])                 request_body = environ['wsgi.input'].read(request_body_size)             except (TypeError, ValueError):                 request_body = '0'             try:                 response_body = str(request_body)             except:                 response_body = 'error'             status = '200 OK'             headers = [('Content-type', 'text/plain')]             start_response(status, headers)             return [response_body]     else:         response_body = open('test.html').read()         status = '200 OK'         headers = [('Content-type', 'text/html'),                     ('Content-Length', str(len(response_body)))]         start_response(status, headers)         return [response_body]
