Using Proxies for HTTPS requests

[Tracy Moore]

I'm using urllib2 to make several HTTP and HTTPS requests. My problem is that I'm unable to make HTTPS requests through a proxy, as the GAE httplib wont allow tunneling.

Is there anyway around this?

I assume you're getting NotImplementedError - HTTP CONNECT Tunnelling is not supported?

Sorry to say this, but there's no way around it. You'll have to find a different way to connect to the proxy and tell it what to retrieve - for instance, the proxy could implement a HTTP API that you could then call out to using basic urlfetch.

Another alternative is to use a Managed VM and access the proxy from there, or use a prebuilt solution such as Blockspring.

sockets api?

See the "Making httplib use sockets" section.

Yup - doing this with Blockspring is pretty easy. Let me know if you need any help.

I've discovered some workarounds, but I'm having some other issues (at least it works ok on the deploy): https://stackoverflow.com/questions/49409783/google-app-engine-permission-denied-proxy-tunneling-on-development-server
Solution: just enable httplib sockets into the app.yaml file, but don't expect to have it working ok on the development server :).
