### 直接回傳 Response { #return-a-response-directly }

最常見的情況是[直接回傳 Response（在進階文件中稍後會解釋）](../advanced/response-directly.md)。

{* ../../docs_src/response_model/tutorial003_02_py310.py hl[8,10:11] *}

這個簡單情境會由 FastAPI 自動處理，因為回傳型別註解是 `Response` 類別（或其子類別）。

而工具也會滿意，因為 `RedirectResponse` 與 `JSONResponse` 都是 `Response` 的子類別，所以型別註解是正確的。

### 註解為某個 Response 的子類別 { #annotate-a-response-subclass }

## 添加正则表达式 { #add-regular-expressions }

你可以定义一个参数必须匹配的 <dfn title="正则表达式（regex 或 regexp）是用于定义字符串搜索模式的字符序列。">正则表达式</dfn> `pattern`：

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

这个特定的正则表达式通过以下规则检查接收到的参数值：

- `^`：必须以接下来的字符开头，前面没有其他字符。
- `fixedquery`：值必须精确等于 `fixedquery`。
- `$`：到此结束，在 `fixedquery` 之后没有更多字符。

如果你对这些**「正则表达式」**概念感到迷茫，不必担心。对很多人来说这都是个难点。你仍然可以在不使用正则表达式的情况下做很多事情。
