Python: Obtain a URL

问题

Because I cant get this working: Python: KeyError with form.getfirst

I have an alternative option, I have a function in DTML which needs to obtain a URL:

For example if the dtml webpage is located at

www.blah.com/foo/foo2?variable=55

How would i obtain the URL of this page using a python function?

The function is called by:

<dtml-var test>

The syntax for "test" is rite, the Zope documentation says so.

回答1:

for: http://www.blah.com/foo/foo2?job_ID=55555&test=1

<dtml-var URL> = http://www.blah.com/foo/foo2

<dtml-var QUERY_STRING> = job_ID=55555&test=1

<dtml-var "REQUEST['job_ID']"> = 55555
