# Behind a Proxy

In some situations, you might need to use a **proxy** server like Traefik or Nginx with a configuration that adds an extra path prefix that is not seen by your application.

In these cases you can use `root_path` to configure your application.

The `root_path` is a mechanism provided by the ASGI specification (that FastAPI is built on, through Starlette).

The `root_path` is used to handle these specific cases.

FastAPI supports dependencies that do some <abbr title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</abbr>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.

但本节以 `PATCH` 为例的原因是，该操作就是为了这种用例创建的。

注意，输入模型仍需验证。

因此，如果希望接收的部分更新数据可以省略其他所有属性，则要把模型中所有的属性标记为可选（使用默认值或 `None`）。

为了区分用于**更新**所有可选值的模型与用于**创建**包含必选值的模型，请参照[更多模型](extra-models.md){.internal-link target=_blank} 一节中的思路。

Um zu unterscheiden zwischen Modellen für **Aktualisierungen**, mit lauter optionalen Werten, und solchen für die **Erzeugung**, mit benötigten Werten, können Sie die Techniken verwenden, die in [Extramodelle](extra-models.md){.internal-link target=_blank} beschrieben wurden.
