Puedes pensar en `APIRouter` como una clase "mini `FastAPI`".

Se soportan todas las mismas opciones.

Todos los mismos `parameters`, `responses`, `dependencies`, `tags`, etc.

/// tip | Consejo

En este ejemplo, la variable se llama `router`, pero puedes nombrarla como quieras.

変数`oauth2_scheme`は`OAuth2PasswordBearer`のインスタンスですが、「呼び出し可能」です。

次のように、呼ぶことができます:

```Python
oauth2_scheme(some, parameters)
```

そのため、`Depends`と一緒に使うことができます。

### 使い方

これで`oauth2_scheme`を`Depends`で依存関係に渡すことができます。
