* To fix a typo you found on the documentation.
* To share an article, video, or podcast you created or found about FastAPI by <a href="https://github.com/tiangolo/fastapi/edit/master/docs/en/data/external_links.yml" class="external-link" target="_blank">editing this file</a>.

### The callback path expression

* *路径*可以包含 <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#key-expression" class="external-link" target="_blank">OpenAPI 3 表达式</a>（详见下文），可以使用带参数的变量，以及发送至您的 API 的原始请求的部分

### 回调路径表达式

回调*路径*支持包含发送给您的 API 的原始请求的部分的  <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#key-expression" class="external-link" target="_blank">OpenAPI 3 表达式</a>。

本例中是**字符串**：

Salut! 👋

C'est moi :

{% if people %}
<div class="user-list user-list-center">
{% for user in people.maintainers %}

<div class="user"><a href="{{ user.url }}" target="_blank"><div class="avatar-wrapper"><img src="{{ user.avatarUrl }}"/></div><div class="title">@{{ user.login }}</div></a> <div class="count">Réponses: {{ user.answers }}</div><div class="count">Pull Requests: {{ user.prs }}</div></div>
{% endfor %}

</div>
{% endif %}

... y luego puedes tener el path `/users/{user_id}` para obtener los datos sobre un usuario específico asociados a un ID de usuario.

Porque las *operaciones de path* son evaluadas en orden, tienes que asegurarte de que el path para `/users/me` sea declarado antes que el path para `/users/{user_id}`:

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003.py!}
```

* 提出新**特性**建议

**注意**：如果您创建 Issue，我会要求您也要帮助别的用户。😉

## 创建 PR

您可以创建 PR 为源代码做[贡献](contributing.md){.internal-link target=_blank}，例如：

* 修改文档错别字
* <a href="https://github.com/tiangolo/fastapi/edit/master/docs/en/data/external_links.yml" class="external-link" target="_blank">编辑这个文件</a>，分享 FastAPI 的文章、视频、博客，不论是您自己的，还是您看到的都成
    * 注意，添加的链接要放在对应区块的开头
* [翻译文档](contributing.md#_8){.internal-link target=_blank}
    * 审阅别人翻译的文档

E então você pode ter também uma rota `/users/{user_id}` para pegar dados sobre um usuário específico associado a um ID de usuário.

Porque as operações de rota são avaliadas em ordem, você precisa ter certeza que a rota para `/users/me` está sendo declarado antes da rota `/users/{user_id}`:

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003.py!}
```

`/users/me`처럼, 현재 사용자의 데이터를 가져온다고 합시다.

사용자 ID를 이용해 특정 사용자의 정보를 가져오는 경로 `/users/{user_id}`도 있습니다.

*경로 작동*은 순차적으로 실행되기 때문에 `/users/{user_id}` 이전에 `/users/me`를 먼저 선언해야 합니다:

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003.py!}
```

그렇지 않으면 `/users/{user_id}`는 `/users/me` 요청 또한 매개변수 `user_id`의 값이 `"me"`인 것으로 "생각하게" 됩니다.
