firebase-admin-python sdk on app engine

[Ozgun Gunay]

I need to use firebase-admin-python sdk on app engine  (python 2.7). 

https://github.com/firebase/firebase-admin-python

I installed the library under lib folder in my project;

pip install -t lib/ firebase-admin

I noticed that it has *.pyc files, which doesn't support from google.

Also, when I try to import the library with below command, I get error;

from lib.firebase_admin import credentials

Can this library works on the appengine? if yes, How? if no, What do you recommend?

Thanks

Hi Ozgun, great questions. Could you file this against the Python Admin SDK repo? I'll ping our guru to check it out.

Hi Ozgun,

A teammate of mine ran into the exact same thing the other day, and he got around it.  Here;s what he said:

"""

you can delete the .pyc files as they are just the precompiled versions of the .py files that are also there (and will be regenerated when .py is executed).

importing from lib worked for me after I added the appengine_config.py to my project root with the following content:

from google.appengine.ext import vendor

# Add any libraries installed in the "lib" folder.

vendor.add('lib')

I also had to explicitly NOT load the package from the app.yaml

"""

Hope that helps!

Also depending on how you use the SDK in App Engine, you might also have to do the additional steps documented at https://google-auth.readthedocs.io/en/latest/user-guide.html#the-app-engine-standard-environment.

Hi Samuel,

I did what you recommend. Probably it started to work. Thanks.

But I get IncompleteRead error, while trying to create a new user with below code .

How did your teammate solve this problem?

I solved with requests-toolbelt module, which is described in https://stackoverflow.com/questions/9604799/can-python-requests-library-be-used-on-google-app-engine

pip install -t lib/ requests-toolbelt and below code in appengine_config.py:

import requests
import requests_toolbelt.adapters.appengine

# Use the App Engine Requests adapter. This makes sure that Requests uses
# URLFetch.
requests_toolbelt.adapters.appengine.monkeypatch()

# also monkey patch platform.platform() from https://code.google.com/p/googleappengine/issues/detail?id=12982
import platform

def patch(module):
    def decorate(func):
        setattr(module, func.func_name, func)
        return func
    return decorate


@patch(platform)
def platform():
    return 'AppEngine'

Hey Ozgun,

Glad you solved this, and thanks for sharing your solution with the community!
