只是因為這是很常見的用例，所以 **FastAPI** 直接內建提供，讓事情更簡單。

///

### 使用表單資料 { #use-the-form-data }

/// tip

`OAuth2PasswordRequestForm` 這個依賴類別的實例不會有以空白分隔長字串的 `scope` 屬性，而是會有一個 `scopes` 屬性，裡面是各個 scope 的實際字串清單。

本示例沒有使用 `scopes`，但如果你需要，功能已經在那裡了。

///

現在，從（假的）資料庫裡用表單欄位的 `username` 取得使用者資料。

如果沒有該使用者，就回傳「Incorrect username or password」的錯誤。

我們用 `HTTPException` 這個例外來回傳錯誤：

```

::: fastapi.Depends

## `Security()`

For many scenarios, you can handle security (authorization, authentication, etc.) with dependencies, using `Depends()`.

But when you want to also declare OAuth2 scopes, you can use `Security()` instead of `Depends()`.

You can import `Security()` directly from `fastapi`:

```python
from fastapi import Security
```

<img src="/img/tutorial/security/image10.png">

/// note | 注意

留意標頭 `Authorization`，其值是以 `Bearer ` 開頭。

///

## 進階用法：`scopes` { #advanced-usage-with-scopes }

OAuth2 有「scopes」的概念。

你可以用它們替 JWT 權杖加上一組特定的權限。

接著你可以把這個權杖直接交給某個使用者或第三方，讓他們在一組受限條件下與你的 API 互動。

你可以在之後的「進階使用者指南」學到如何使用它們，以及它們如何整合進 **FastAPI**。
