Google App Engine 1 (Python 2) Issue for making requests to algolia

[ernsnl]

• Version: 2.4.0

Underlying cause

I am using Algolia in Google App Engine (GAE1) and we are using requests library to issue requests as well. However, due to GAE1 limitations, we need to use an additional library called requests_toolbelt. This library changes underlying requests library to use urlfetch. Details of that can be found here.

In Requester, Algolia library is importing HttpAdapter which is the wrong adapter for the GAE1 that using requests library. It needs to import AppEngineAdapter from requests_toolbelt to correctly read the response otherwise request will fail.

I have fixed the problem by introducing a custom code.

import sys
if sys.version_info >= (3, 0):
  self._session.mount("https://", HTTPAdapter(max_retries=Retry(connect=0)))
else:
  from requests_toolbelt.adapters.appengine import AppEngineAdapter
  self._session.mount('https://', AppEngineAdapter(max_retries=Retry(connect=0)))

This solution only works for the GAE1 which is fine for me. This issue is also can be closed. However, it would be helpful to have a section in Algolia Docs to mention this problem since it will affect other App Engine users.
