@singingwolfboy Your pull request in #493 had a lot of fixes for this. If you're up for it, you could merge against the latest urllib3 which supports AppEngine and just make the requests-specific changes without introducing Py25 support. :)

@kennethreitz How do you want to handle merging in the latest urllib3? Once that's dealt with, I can make the necessary changes to make requests compatible with App Engine on Python 2.7.

@shazow I'm a bit of a noob but could try my hand at a merge.... this would be incredibly helpful to those of us in the python environment on app engine!

[kennethreitz]

Urllib3 changes have already been merged.

I need to actually spin up an account and see what's wrong I guess :)

Hey, I just tried this again with the current master branch. Looks like the same AttributeError referenced in the above stackoverflow post, which @shazow mentioned probably has to do with using the local filesystem for certain things in Requests. The local filesystem is not available on AppEngine- I tend to use StringIO in a lot cases where I'd relied on the file system in the past, but not sure how how helpful that is.

@rdixit can you try it again with the latest from the develop branch?

Hi, tried it with the develop branch, but I think it's the same issue as OP.

from libraries import requests

response = requests.get('http://www.google.com')

Ah, interesting. One more quick fix here...

[kennethreitz]

Care to try again?

Thanks for this by the way :)

No problem, I'm happy to help even in a small way.

Here's the new traceback:
