La variable `oauth2_scheme` es una instance de `OAuth2PasswordBearer`, pero también es un "callable".

Podría ser llamada como:

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

Así que, puede usarse con `Depends`.

### Úsalo { #use-it }

Ahora puedes pasar ese `oauth2_scheme` en una dependencia con `Depends`.

那是因為它沿用了 OpenAPI 規格中的名稱。如此一來，若你要深入查閱這些安全方案，便能直接複製貼上去搜尋更多資訊。

///

變數 `oauth2_scheme` 是 `OAuth2PasswordBearer` 的實例，但同時它也是「可呼叫的」（callable）。

它可以這樣被呼叫：

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

因此它可以配合 `Depends` 使用。

### 如何使用 { #use-it }

現在你可以在相依性中傳入 `oauth2_scheme` 與 `Depends` 搭配。

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

这是因为它使用了与 OpenAPI 规范中相同的名称。这样当你需要深入了解这些安全方案时，可以直接复制粘贴去查找更多信息。

///

`oauth2_scheme` 变量是 `OAuth2PasswordBearer` 的一个实例，同时它也是“可调用”的。

可以像这样调用：

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

因此，它可以与 `Depends` 一起使用。

### 使用 { #use-it }

现在你可以通过 `Depends` 将 `oauth2_scheme` 作为依赖传入。
