gmail oauth2 got stuck

[szguoxz]

Anyone tried to connect to gmail imap using email and access-token?
It simply go dead on me. Tried a couple days, nothing worked.
I simply use the example code.
It dies on client.Authenticate("XOAUTH2", @Gmailauth)

Who had any success? by the way, I use runtime-tokio feature.

I'm experiencing the same issue with runtime-tokio. The future never resolves, and my program hangs indefinitely.

Faced the same issue.
This happens because the Gmail IMAP server sends a greeting message. To fix it, add this before the authentication

let _greeting = client.read_response().await?.expect("unexpected end of stream, expected greeting");

Is this part of the normtal protocol? Should the lib take care of this? Or is this just something google play dirty?

Yes, greeting is part of the protocol.
We at least need to fix examples/src/bin/gmail_oauth2.rs to read the greeting.
Better API would be nice as well.
