Do grpc c++ clients support proxies?

[Stephan Menzel]

Hello all,

I am using several c++ client implementations for grpc services and I would like to enable them to go through proxies. Ideally SOCKS5 but http would be acceptable as well. Now my question is, does grpc support this out of the box?

This is how I instantiate the client:

m_stub = MyService::NewStub(grpc::CreateChannel(hostname, grpc::InsecureChannelCredentials()));

Pretty straight forward, on grpc 1.21.4 right now. Can I just give any parameter of sorts to enable this?

In case not, are there any experiences as to how to make that work?

Cheers,

Stephan

digging through the source I believe I've figured out at least one way.

If I set an environment variable like this: http_proxy="http://127.0.0.1:8118"

... gRPC appears to honor it and send the requests through the proxy. Good start. Still, SOCKS5? My application will require it anyway and I'd like to use one proxy for everything.
