  1. docs/en/docs/advanced/response-headers.md

    And then you can set headers in that *temporal* response object.
    
    ```Python hl_lines="1  7-8"
    {!../../docs_src/response_headers/tutorial002.py!}
    ```
    
    And then you can return any object you need, as you normally would (a `dict`, a database model, etc).
    
    And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

  2. docs/zh/docs/advanced/events.md

    使用 `startup` 事件声明 `app` 启动前运行的函数:
    
    ```Python hl_lines="8"
    {!../../docs_src/events/tutorial001.py!}
    ```
    
    本例中,`startup` 事件处理器函数为项目数据库(只是**字典**)提供了一些初始值。
    
    **FastAPI** 支持多个事件处理器函数。
    
    只有所有 `startup` 事件处理器运行完毕,**FastAPI** 应用才开始接收请求。
    
    ## `shutdown` 事件
    
    使用 `shutdown` 事件声明 `app` 关闭时运行的函数:
    
    ```Python hl_lines="6"
    {!../../docs_src/events/tutorial002.py!}
    ```
    
    此处,`shutdown` 事件处理器函数在 `log.txt` 中写入一行文本 `Application shutdown`。

    ## Validações numéricas: maior que e menor que ou igual
    
    O mesmo se aplica para:
    
    * `gt`: maior que (`g`reater `t`han)
    * `le`: menor que ou igual (`l`ess than or `e`qual)

  4. docs/fr/docs/tutorial/query-params.md

    ## Paramètres optionnels
    
    De la même façon, vous pouvez définir des paramètres de requête comme optionnels, en leur donnant comme valeur par défaut `None` :
    
    {* ../../docs_src/query_params/tutorial002.py hl[9] *}
    
    Ici, le paramètre `q` sera optionnel, et aura `None` comme valeur par défaut.

  10. docs/zh/docs/advanced/response-headers.md

    # 响应头
    
    ## 使用 `Response` 参数
    
    你可以在你的*路径操作函数*中声明一个`Response`类型的参数(就像你可以为cookies做的那样)。
    
    然后你可以在这个*临时*响应对象中设置头部。
    ```Python hl_lines="1  7-8"
    {!../../docs_src/response_headers/tutorial002.py!}
    ```
    
    然后你可以像平常一样返回任何你需要的对象(例如一个`dict`或者一个数据库模型)。如果你声明了一个`response_model`,它仍然会被用来过滤和转换你返回的对象。
    
    **FastAPI**将使用这个临时响应来提取头部(也包括cookies和状态码),并将它们放入包含你返回的值的最终响应中,该响应由任何`response_model`过滤。
    
    你也可以在依赖项中声明`Response`参数,并在其中设置头部(和cookies)。
    
    ## 直接返回 `Response`
