You can now get the current user directly in your *path operation function*.

We are already halfway there.

We just need to add a *path operation* for the user/client to actually send the `username` and `password`.

 *  **Web Sockets are now a stable feature of OkHttp.** Since being introduced as a beta feature in
    OkHttp 2.3 our web socket client has matured. Connect to a server's web socket with
    `OkHttpClient.newWebSocket()`, send messages with `send()`, and receive messages with the
    `WebSocketListener`.

A **FastAPI** fornece o mesmo `WebSocket` diretamente apenas como uma conveniência para você, o desenvolvedor. Mas ele vem diretamente do Starlette.

## Aguarde mensagens e envie mensagens { #await-for-messages-and-send-messages }

Em sua rota WebSocket você pode esperar (`await`) por mensagens e enviar mensagens.

Você pode receber e enviar dados binários, de texto e JSON.
