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`.

Wir haben bereits die Hälfte geschafft.

Wir müssen jetzt nur noch eine *Pfadoperation* hinzufügen, mittels der der Benutzer/Client tatsächlich seinen `username` und `password` senden kann.

    *以下几种流程适合构建 OAuth 2.0 身份认证的提供者（例如 Google，Facebook，X (Twitter)，GitHub 等）：
        * `implicit`
        * `clientCredentials`
        * `authorizationCode`
    * 但是有一个特定的「流程」可以完美地用于直接在同一应用程序中处理身份认证：
        * `password`：接下来的几章将介绍它的示例。
* `openIdConnect`：提供了一种定义如何自动发现 OAuth2 身份认证数据的方法。
    * 此自动发现机制是 OpenID Connect 规范中定义的内容。


/// tip

集成其他身份认证/授权提供者（例如Google，Facebook，X (Twitter)，GitHub等）也是可能的，而且较为容易。

Agora você pode obter o usuário atual diretamente na sua *função de operação de rota*.

Já estamos na metade do caminho.

Só precisamos adicionar uma *operação de rota* para que o usuário/cliente realmente envie o `username` e `password`.
