REDIRECT

[gaeasiankom]

Hi !

I'm new to Python. I'm having some difficulties to redirect the pages
using python. Every time when I redirect, the URL changed accordingly.

(Example : from http://localhost:9999 to http://localhost/hello.py?name='J')

What's the Python way of implementing this ? Can anyone help me out on
this ?



Thanks in advance,

J

What did you try so far? Hint: the redirect is done via Location:
HTTP-Header. You can check all details in rfc2616, this is independend
from the language you would use. Everything else depends on the
framework you use.

Hi Tino !


Thanks for your reply. Currently I'm using :

1. Eclipse SDK, Version: 3.4.1 (I have set up python plug in - I used
PyDev)
2. Python, Version 2.5.4
3. GoogleAppEngine, Version 1.1.9
(webapp - framework)

What actually I'm try to do is :

I'm having a Login page which developed in HTML. When I click on the
"Login" button I want the page to validate (at datastore of google
app) using python and redirect to other HTML page. As what I
understand, Python is the only language that supported by the
GoogleApps.


I did try by using below lines :

print 'Status: 302 Moved Temporarily'
print "Location: test.html"
print 'Pragma: no-cache'
print 'Content-Type: text/html'

but error thrown as:

Not found error: /test.html did not match any patterns in application
configuration.



Please advice me on this.

your cooperation higly appreciated.



note : I'm not able to view the file that u attched in your previous
mail (smime.p7s).


Regards,

J

The webapp framework that comes with the Google Apps SDK has a function
for redirecting:

Thanks again. I went through that page earlier but I'm not clear with
the procedures.

Sample that I did :

class FormHandler(webapp.RequestHandler):
def post(self):
if processFormData(self.request):
self.redirect("/test.html")
else:
print 'Hello'

I failed to redirect. Error :
