Permission Denied Error When opening Socket to APNS on Google AppEngine Development

Question

I'm trying to make my app engine server send APNS notifications, and for that I'm using template code I got from this project (which is said to work, so it's possible): https://github.com/GarettRogers/appengine-apns-gcm

For now, I want to make this work on my local development.

When getting to actually trying to open the socket, I get the error stack below.

My guess is that maybe app engine needs sudo permissions to do this (I'm using a mac). If so - does anyone know how I can make app engine run with sudo permissions?

If not - can anyone tell me what the problem is and how to fix it?

Thanks.

Yes. But again, I need this to run on my dev instance, since I don't want to debug on my prod. As written in the Google AppEngine docs, this should be possible… — Lior Z

I missed that, your trying on dev. So just run the dev server from the command line with sudo. — Tim Hoffman

Did that - didn't work. Maybe it's something with the connection itself or a flag I need to set? — Lior Z

Same problem happening to me with the sample program using flask... Tried to run with admin permissions on windows but got the exact same error when trying to bind the server socket... — El Ninja Trepador

Apply this: "ImportError: No module named _ssl" with dev_appserver.py from Google App Engine

The question/answer explains it all, I won't go into detail, It's a long standing SDK deficiency, this manual method patches it, you need to apply it each time you update the SDK

I solved this via

pip install requests-toolbelt -t lib

then add

from requests_toolbelt.adapters import appengine
appengine.monkeypatch()

source: Can Python Requests library be used on Google App Engine?
