Question

For instance I want to visit http://localhost:8080/?var=val or similar with POST, but I get a 500 server error:

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Traceback (most recent call last):
 File "c:\python26\lib\site-packages\cherrypy\_cprequest.py", line 606, in respond
   cherrypy.response.body = self.handler()
 File "c:\python26\lib\site-packages\cherrypy\_cpdispatch.py", line 25, in __call__
   return self.callable(*self.args, **self.kwargs)
TypeError: index() takes no arguments (1 given)

Answer 1

It is definitely possible.

Here is an example (adapted from the CherryPy tutorial):

<form action="indexPostHandler" method="post">
    <p>Enter a value:</p>
    <input type="text" name="val" value=""/>
    <p><input type="submit" value="Login"/></p>
</form>

And, in your index, you can use something like the following to process the request:

class Root:
    # create form here
    def indexPostHandler(self, val=None):
        # do something with val here
        ...
