Get parameters from the URL

[Sohrab Pawar]

Hi all,

I'm a python noob so don't be mean :)
I have a URL like http://mySite.net?userID=398&age=28
I'm trying to create a new python script that is called when a user
click a button "Redirect". When a user clicks the "Redirect" button, I
want to send the user to either of the 2 pages, depending on the age of
the user (sent as a parameter using the URL).

What is the best way to
1. Read the URL and get the parameters (age=28 in this case)
2. Redirect the the user accordingly

I have done this kind of thing in a jsp/servlet environment but I have
no idea how to proceed in the Python world.

Any advice/example would help.

Regards,
Sohrab

If you really got that string you can use the modules `urlparse` and
`cgi` to get the query part:

In [48]: url = 'http://mySite.net?user ID=398&age=28'

In [49]: urlparse.urlpar se(url)
Out[49]: ('http', 'mySite.net', '', '', 'userID=398&age =28', '')

In [50]: cgi.parse_qs(ur lparse.urlparse (url)[4])
Out[50]: {'age': ['28'], 'userID': ['398']}

But maybe you should read about the `cgi` module and how to use it.
