# 响应状态码

与指定响应模型的方式相同，在以下任意*路径操作*中，可以使用 `status_code` 参数声明用于响应的 HTTP 状态码：

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* 等……

```Python hl_lines="6"
{!../../docs_src/response_status_code/tutorial001.py!}
```

/// note | "笔记"

注意，`status_code` 是（`get`、`post` 等）**装饰器**方法中的参数。与之前的参数和请求体不同，不是*路径操作函数*的参数。

///

`status_code` 参数接收表示 HTTP 状态码的数字。

/// info | "说明"
