Question

i am using python 2.6.5 to develop an app for google app engine – i am not too familiar with python, but i’m learning.

i am trying to put a url into a string so variable = “string http://domain.name“

then i print the string out. the problem is, if the colon (after http) is in the string, i don’t get any output and i don’t know why.

i’ve tried escaping the string with:

• “””http://domain.name”””
• r”http://domain.name”
• “http\://domain.name”
• “http\://domain.name”
• “http\\://domain.name”
• “http:://domain.name”

none of them seem to work and i’m not sure what else to try

The context is like so

variables.py is:

...
HOST_URL = "http://domain.name"
...

example logout.py

import variables
import sys

...

class Logout(webapp.RequestHandler):
    """ RequestHandler for when a user wishes to logout from the system."""
    def post(self):
        self.get()

    def get(self):
        print(variables.HOST_URL)
        print('hi')
        self.redirect(variables.HOST_URL)
        sys.exit()

or

in file functions.py

import variables
import sys

...

def sendhome(requesthandler)
    print 'go to '+variables.HOST_URL
    requesthandler.redirect(variables.HOST_URL)
    sys.exit()

called from a context like:

from functions import sendhome

...

class Logout(webapp.RequestHandler):
    """ RequestHandler for when a user wishes to logout from the system."""
    def post(self):
        self.get()

    def get(self):
        sendhome(self)

any help would be appreciated

thanks

If I’m not terrible mistaken, GAE uses WSGI, you do not simply print things, you are supposed to return a proper HTTP response object (it is not PHP).

I guess that if you access the page using firefox+firebug and look at the network->header you will see that the browser is taking http: as an HTTP header with value “//domain.name”.

Edited: By the way, should not you be using “self.response.out.write” instead of “print”?
