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"
{!../../../docs_src/security/tutorial003.py!}
```

!!! 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。

    다음 장에서는 패스워드 해싱 및 <abbr title="JSON Web Tokens">JWT</abbr> 토큰을 사용하여 실제 보안 구현을 볼 수 있습니다.

    하지만 지금은 필요한 세부 정보에 집중하겠습니다.
