Es könnte wie folgt aufgerufen werden:

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

Es kann also mit `Depends` verwendet werden.

### Verwenden { #use-it }

Jetzt können Sie dieses `oauth2_scheme` als Abhängigkeit `Depends` übergeben.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

///

`oauth2_scheme` 变量是 `OAuth2PasswordBearer` 的实例，也是**可调用项**。

以如下方式调用：

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

因此，`Depends` 可以调用 `oauth2_scheme` 变量。

### 使用

接下来，使用 `Depends` 把 `oauth2_scheme` 传入依赖项。

{* ../../docs_src/security/tutorial001.py hl[10] *}

该依赖项使用字符串（`str`）接收*路径操作函数*的参数 `token` 。

**FastAPI** 使用依赖项在 OpenAPI 概图（及 API 文档）中定义**安全方案**。

Ela pode ser chamada como:

```Python
oauth2_scheme(some, parameters)

Então, pode ser usada com `Depends`.

### Use-o { #use-it }

Agora você pode passar esse `oauth2_scheme` em uma dependência com `Depends`.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

Podría ser llamada como:

```Python

Así que, puede usarse con `Depends`.

### Úsalo { #use-it }
