    - 但該端點需要驗證。
    - 因此為了向 API 驗證，請求會帶上一個 `Authorization` 標頭，值為 `Bearer ` 加上 token。
    - 例如 token 是 `foobar`，則 `Authorization` 標頭內容為：`Bearer foobar`。

## FastAPI 的 `OAuth2PasswordBearer` { #fastapis-oauth2passwordbearer }

FastAPI 提供多層抽象的工具來實作這些安全機制。

本例將使用 OAuth2 的 Password 流程，並以 Bearer token 進行驗證；我們會用 `OAuth2PasswordBearer` 類別來完成。

/// info

「Bearer」token 不是唯一選項。

但對本例最合適。

    * 因此，为了与我们的 API 进行身份验证，它会发送一个 `Authorization` 请求头，值为 `Bearer ` 加上令牌。
    * 如果令牌内容是 `foobar`，`Authorization` 请求头的内容就是：`Bearer foobar`。

## **FastAPI** 的 `OAuth2PasswordBearer` { #fastapis-oauth2passwordbearer }

**FastAPI** 在不同抽象层级提供了多种安全工具。

本示例将使用 **OAuth2** 的 **Password** 流程并配合 **Bearer** 令牌，通过 `OAuth2PasswordBearer` 类来实现。

/// info | 信息

“Bearer” 令牌并非唯一选项。

但它非常适合我们的用例。
