Jetzt, selbst wenn Sie einen <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> mit duplizierten Daten erhalten, werden diese zu einem Set eindeutiger Dinge konvertiert.

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。

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`。

이 경우, `HTTPException`이나 유사한 예외를 발생시키지 않기 때문에 클라이언트는 HTTP 500 Internal Server Error 응답을 보게 되지만, 서버는 어떤 오류가 발생했는지에 대한 **로그**나 다른 표시를 전혀 가지지 않게 됩니다. 😱

### `yield`와 `except`를 사용하는 의존성에서 항상 `raise` 하기

`yield`가 있는 의존성에서 예외를 잡았을 때는 `HTTPException`이나 유사한 예외를 새로 발생시키지 않는 한, 반드시 원래의 예외를 다시 발생시켜야 합니다.

## What is "Form Data" { #what-is-form-data }

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

**FastAPI** will make sure to read that data from the right place instead of JSON.
