Python Requests seems to work fine on production, but you will bump into the following error on development server
File "/*/requests/adapters.py", line 490, in send raise ConnectionError(err, request=request) ConnectionError: ('Connection aborted.', error(13, 'Permission denied'))
To fix it, import requests-toolbelt in your equivelant of
import requestsimport requests_toolbelt.adapters.appengine# Use the App Engine Requests adapter. This makes sure that Requests uses URLFetch.requests_toolbelt.adapters.appengine.monkeypatch()
In production, you will still bump into the following error (which is actually a warning).
AppEnginePlatformWarning: urllib3 is using URLFetch on Google App Engine sandbox instead of sockets. To use sockets directly instead of URLFetch see https://urllib3.readthedocs.io/en/latest/reference/urllib3.contrib.html.
You can ignore the above error/warning, or you can enable making httplib use sockets.
app.yaml and add the following.
env_variables: GAE_USE_SOCKETS_HTTPLIB : 'anyvalue'
NOTE: I stick with UrlFetch at the moment and didn't try the Sockets solution.
