This must be a very simple question, but I don’t seem to be able to figure out.

I’m using apache + mod_wsgi to host my python application, and I’d like to get the post content submitted in one of the forms -however, neither the environment values, nor sys.stdin contains any of this data. Mind giving me a quick hand?

Edit: Tried already:

  • environ[‘CONTENT_TYPE’] = ‘application/x-www-form-urlencoded’ (no data)
  • environ[‘wsgi.input’] seems a plausible way, however, both environ[‘wsgi.input’].read(), and environ[‘wsgi.input’].read(-1) returns an empty string (yes, content has been posted, and environ[‘request_method’] = ‘post’

  1. PEP 333 says you must read environ[‘wsgi.input’].

    I just saved the following code and made apache’s mod_wsgi run it. It works.

    You must be doing something wrong.

    from pprint import pformat  def application(environ, start_response):     # show the environment:     output = ['<pre>']     output.append(pformat(environ))     output.append('</pre>')      #create a simple form:     output.append('<form method='post'>')     output.append('<input type='text' name='test'>')     output.append('<input type='submit'>')     output.append('</form>')      if environ['REQUEST_METHOD'] == 'POST':         # show form data as received by POST:         output.append('<h1>FORM DATA</h1>')         output.append(pformat(environ['wsgi.input'].read()))      # send results     output_len = sum(len(line) for line in output)     start_response('200 OK', [('Content-type', 'text/html'),                               ('Content-Length', str(output_len))])     return output
