How to catch POST using WSGIREF

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()

From stackoverflow

• 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]
  

  alfredodeza : Thanks, this was exactly what I needed! One modification though, was to add [5:] to response_body to avoid the 'size=' part.
