based server to register tf.function methods and a GRPC client to invoke
        remote registered methods. RPC APIs are intended for multi-client setups
        i.e. server and clients are started in separate binaries independently.

    *   Example usage to create server: ```python server =
        tf.distribute.experimental.rpc.Server.create("grpc", "127.0.0.1:1234")

    if (typeof define === 'function' && define.amd) {
        // AMD. Make globaly available as well
        define(['moment', 'jquery'], function (moment, jquery) {
            if (!jquery.fn) jquery.fn = {}; // webpack server rendering
            if (typeof moment !== 'function' && moment.hasOwnProperty('default')) moment = moment['default']
            return factory(moment, jquery);
        });

### Lancez

Lancez le serveur avec :

<div class="termy">

```console
$ uvicorn main:app --reload

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [28720]
INFO:     Started server process [28722]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
```

使用以下指令運行伺服器：

<div class="termy">

```console
$ uvicorn main:app --reload

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [28720]
INFO:     Started server process [28722]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
```

/// note | "Hinweis"

Es ist üblich, dass jeder Authentifizierungsanbieter seine Flows anders benennt, um sie zu einem Teil seiner Marke zu machen.

Aber am Ende implementieren sie denselben OAuth2-Standard.

///

**FastAPI** enthält Werkzeuge für alle diese OAuth2-Authentifizierungs-Flows in `fastapi.security.oauth2`.

* und finde dort das Modul `dependencies` (die Datei unter `app/dependencies.py`) ...
* und importiere daraus die Funktion `get_token_header`.

Das würde sich auf ein Paket oberhalb von `app/` beziehen, mit seiner eigenen Datei `__init__.py`, usw. Aber das haben wir nicht. Das würde in unserem Beispiel also einen Fehler auslösen. 🚨

O uso de `Optional[str]` em vez de apenas `str` permitirá que o editor o ajude a detectar erros, onde você pode estar assumindo que um valor é sempre um `str`, quando na verdade também pode ser `None`.

`Optional[Something]` é na verdade um atalho para `Union[Something, None]`, eles são equivalentes.

///

## Mais detalhes sobre `SecurityScopes`

Você pode utilizar `SecurityScopes` em qualquer lugar, e em diversos lugares. Ele não precisa estar na dependência "raiz".

Ele sempre terá os escopos de segurança declarados nas dependências atuais de `Security` e todos os dependentes para **aquela** *operação de rota* **específica** e **aquela** árvore de dependência **específica**.
