按照[直接返回响应](response-directly.md){.internal-link target=_blank}中所述创建响应，并将头部作为附加参数传递：
```Python hl_lines="10-12"
{!../../docs_src/response_headers/tutorial001.py!}
```


/// note | "技术细节"

你也可以使用`from starlette.responses import Response`或`from starlette.responses import JSONResponse`。

**FastAPI**提供了与`fastapi.responses`相同的`starlette.responses`，只是为了方便开发者。但是，大多数可用的响应都直接来自Starlette。

由于`Response`经常用于设置头部和cookies，因此**FastAPI**还在`fastapi.Response`中提供了它。
