How to do user authentication with github? about grpc-web HOT 6 CLOSED

Hey @joenayjoe ,

Could you please clarify the problem you are having? From what you mention, it does not look like a problem with grpc-web itself but rather how to perform user authentication with Github in Go.

Here are some resources that may help https://developer.github.com/v3/guides/getting-started/#authentication

I will close this issue as it does not appear to be directly related to grpc-web. If you feel this is not the case please feel free to comment below and we can take it from there.

Hi @easyCZ ,
Ok I will try to explain my problem. When a user clicks the link to log in with Github, he is redirected to Github authorization endpoint. Upon authorizing with user name and password, the user is redirected back to a callback URL How can I intercept that callback from grpc_web server to get the auth token? Since the callback is not a grpc method, I am not quite sure how to get the information from the callback.
May be I am messing up REST with gRPC.
Thanks

Thanks for clarification. Looking to give you an example now. Reopening

Hi @joenayjoe,

You can provide custom non-grpcweb functionality on the same server.
In the example you can provide a custom handler for any request that reaches the grpcweb server.

For example, we can do the following, since we have access to the request:

handler := func(resp http.ResponseWriter, req *http.Request) {

		if req.URL.Path == "/auth" {
			fmt.Fprintf(resp, "Hi there, I love %s!", req.URL.Path[1:])
			return
		}
		wrappedServer.ServeHTTP(resp, req)
	}

This allows us to bypass the wrapped server and handle any request. You can get more fancy with this by using chi or echo. Let me know if that solves your problem

@easyCZ ,
Thank you for the tips. I tried to make a call to a custom URL and it indeed works.
