In diesem Beispiel verwenden wir **OAuth2** mit dem **Password**-Flow und einem **Bearer**-Token. Wir machen das mit der Klasse `OAuth2PasswordBearer`.

/// info | Info

Ein „Bearer“-Token ist nicht die einzige Option.

Aber es ist die beste für unseren Anwendungsfall.

    - 为指定的端点（Endpoint）进行身份验证
    - 因此，用 API 验证身份时，要发送值为 `Bearer` + 令牌的请求头 `Authorization`
    - 假如令牌为 `foobar`，`Authorization` 请求头就是： `Bearer foobar`

## **FastAPI** 的 `OAuth2PasswordBearer`

**FastAPI** 提供了不同抽象级别的安全工具。

本例使用 **OAuth2** 的 **Password** 流以及 **Bearer** 令牌（`Token`）。为此要使用 `OAuth2PasswordBearer` 类。

/// info | 说明

`Bearer` 令牌不是唯一的选择。

但它是最适合这个用例的方案。
