在示例代码的情况下，客户端将会收到 *HTTP 500 Internal Server Error* 的响应，因为我们没有抛出 `HTTPException` 或者类似的异常，并且服务器也 **不会有任何日志** 或者其他提示来告诉我们错误是什么。😱

### 在包含 `yield` 和 `except` 的依赖项中一定要 `raise`

如果你在使用 `yield` 的依赖项中捕获到了一个异常，你应该再次抛出捕获到的异常，除非你抛出 `HTTPException` 或类似的其他异常，

你可以使用 `raise` 再次抛出捕获到的异常。

{* ../../docs_src/dependencies/tutorial008d_an_py39.py hl[17] *}

现在客户端同样会得到 *HTTP 500 Internal Server Error* 响应，但是服务器日志会记录下我们自定义的 `InternalError`。

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)
