python request module is include in the app engine project. Using python 2.7. Being look for ways to solve this problem but have not find very clear way to solve the problem yet

Answer 1

If you're using GAE's Sockets, you can get SSL support without any hacks by simply loading the SSL library.

Simply add this to your app.yaml file:

libraries: - name: ssl   version: latest 

This is documented on Google Cloud's OpenSSL Support documentation.

Answer 2

This blog post details a solution. From the blog post:

The problem is GAE has a “whitelist” of select standard libraries. SSL (_ssl, _socket) is not one of them. So, we need to tweak the sandbox environment (dangerous) carefully. The below code uses the standard Python socket library instead of the GAE-provided in the development environment. Modify [or create] appengine_config.py:

import os  # Workaround the dev-environment SSL #   http://stackoverflow.com/q/16192916/893652 if os.environ.get('SERVER_SOFTWARE', '').startswith('Development'):     import imp     import os.path     from google.appengine.tools.devappserver2.python import sandbox      sandbox._WHITE_LIST_C_MODULES += ['_ssl', '_socket']     # Use the system socket.     psocket = os.path.join(os.path.dirname(os.__file__), 'socket.py')     imp.load_source('socket', psocket)
