Feature Request: Send HTTP requests from Authenticator

Hi,

I’d like to have a way to send some HTTP requests from the Authenticator because some authentication mechanisms need it in its workflow (for example: OAuth).

As workaround, for the moment,

• I can create a new instance of OkHttpClient but I’m not sure it is a good practice, or
• I can add a setHttpClient method in Authenticator:

MyAuthenticator authenticator = new MyAuthenticator();
OkHttpClient client = new OkHttpClient.Builder()
                .authenticator(authenticator)
                .build();
authenticator.setHttpClient(client);

But

        OkHttpClient client = new OkHttpClient.Builder()
                .authenticator(new MyAuthenticator(client))
                .build();

is not possible.

One workaround is to use OkHttpClient.newBuilder():

1. Create basicClient, an OkHttpClient that’s configured exactly as you want it, but with no Authenticator.
2. Pass the basicClient to your Authenticator constructor
3. Use basicClient.newBuilder(), add the authenticator, then call build() to create your authenticated client. Use this everywhere.

Yep. That’s a big backwards-incompatible change. We’ll add it to the list of things to consider for okhttp4 in 2021.
