遇到这些情况时，通常要返回 **4XX**（400 至 499）**HTTP 状态码**。

这与表示请求成功的 **2XX**（200 至 299）HTTP 状态码类似。那些“200”状态码表示某种程度上的“成功”。

而 **4XX** 状态码表示客户端发生了错误。

大家都知道**「404 Not Found」**错误，还有调侃这个错误的笑话吧？

## 使用 `HTTPException` { #use-httpexception }

向客户端返回 HTTP 错误响应，可以使用 `HTTPException`。

### 导入 `HTTPException` { #import-httpexception }
