It could be called as:

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

So, it can be used with `Depends`.

### Use it { #use-it }

Now you can pass that `oauth2_scheme` in a dependency with `Depends`.

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] *}

此相依性會提供一個 `str`，指派給「路徑操作函式」的參數 `token`。

FastAPI 會知道可以使用這個相依性，在 OpenAPI（以及自動產生的 API 文件）中定義一個「安全性方案」。
