本例只是简单的演示，返回的 Token 就是 `username`，但这种方式极不安全。

!!! tip "提示"

    下一章介绍使用哈希密码和 <abbr title="JSON Web Tokens">JWT</abbr> Token 的真正安全机制。

    但现在，仅关注所需的特定细节。

```Python hl_lines="85"

```

!!! tip "提示"

    按规范的要求，应像本示例一样，返回带有 `access_token` 和 `token_type` 的 JSON 对象。

    这是开发者必须在代码中自行完成的工作，并且要确保使用这些 JSON 的键。
