I want to add support for sessions to fetch() from tools.py.
This is so that I can call protected KML feeds from inside the Sahana
Map Viewing Client.
I think that what I need to do to achieve this is to forward the
session cookie from request to the urllib2() call (yes, it seems that
urllib() is insufficient for this).
I'm really struggling to get this working though.
I've tried adding the header manually:
import urllib2
cookie = response.session_id_name + "=" +
response.session_id
txheaders = {'Cookie' : cookie}
req = urllib2.Request(url, None, txheaders)
return urllib2.urlopen(req).read()
But this seems to hang Web2Py completely!
(Strangely it works fine when I direct at an unprotected external KML
feed!)
I also tried using cookielib:
cookie = request.cookies[response.session_id_name]
jar = cookielib.CookieJar()
jar.set_cookie(cookie)
handler = urllib2.HTTPCookieProcessor(jar)
opener = urllib2.build_opener(handler)
urllib2.install_opener(opener)
return urllib2.urlopen(url).read()
However this fails because it wants cookie.domain to be defined (I
tried defining it as "" but this fails too):
import Cookie, cookielib
cookie = Cookie.SimpleCookie()
cookie[response.session_id_name] = response.session_id
cookie['path'] = "/"
cookie['domain'] = ""
This seems wrong anyway, as Set-Cookie is for Server->Client & I want
Client->Server
Any/All pointers very gratefully received :)
Fran.
