为此，要再创建一个依赖项 `get_current_active_user`，此依赖项以 `get_current_user` 依赖项为基础。

如果用户不存在，或状态为未激活，这两个依赖项都会返回 HTTP 错误。

因此，在端点中，只有当用户存在、通过身份验证、且状态为激活时，才能获得该用户：

```Python hl_lines="58-67  69-72  90"
{!../../docs_src/security/tutorial003.py!}
```

/// info | "说明"

此处返回值为 `Bearer` 的响应头 `WWW-Authenticate` 也是规范的一部分。

任何 401**UNAUTHORIZED**HTTP（错误）状态码都应返回 `WWW-Authenticate` 响应头。

本例中，因为使用的是 Bearer Token，该响应头的值应为 `Bearer`。
