This function is not appropriate for Publisher, which automatically 
handles most of the overhead in your code. Publisher makes form data 
available in the dictionary-like object, req.form:

# foo.py
def showformdata(req):
     formdata = {}
     for key in req.form.keys():
         formdata[key] = req.form[key]
     return formdata

Access the above function like this:

  http://localhost/foo/showformdata?a=123&b=456&b=789

It should return this:

  {'a': '123', 'b': ['456', '789']}

Note that a list will be created if multiple values are returned for the 
same key.
