Setting up Python with WSGI on Apache for a directory

Question

I am trying to setup Python with WSGI for a particular directory on Apache but I am getting the following error:

mod_wsgi (pid=3857): Target WSGI script '/var/www/test/test.py' does not contain WSGI application 'application'.

My test.py contains:

print 'Hello, World!'

And my wsgi.conf contains:

LoadModule wsgi_module modules/mod_wsgi.so

WSGIPythonHome /usr/local/bin/python2.7

Alias /test/ /var/www/test/test.py

<Directory /var/www/test>
    SetHandler wsgi-script
    Options ExecCGI
    Order deny,allow
        Allow from all
</Directory>

On top of all that, interestingly enough, the web browser returns a "404 Not Found" error but thankfully the error_log is a little more enlightening.

What am I doing wrong?

You're using WSGI as though it was CGI (strangely without headers).

What you need to do, for your immediate problem is adapt the following from http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

So that you have application present.

And from the referenced doc.

Note that mod_wsgi requires that the WSGI application entry point be called 'application'. If you want to call it something else then you would need to configure mod_wsgi explicitly to use the other name. Thus, don't go arbitrarily changing the name of the function. If you do, even if you set up everything else correctly the application will not be found.

I know this is out of date, but this returns ` TypeError: sequence of byte string values expected, value of type str found` for me
