✍ 📨 🔬 [📨 📨 🔗](response-directly.md){.internal-link target=_blank} & 🚶‍♀️ 🎚 🌖 🔢:

```Python hl_lines="10-12"
{!../../docs_src/response_headers/tutorial001.py!}
```

/// note | "📡 ℹ"

👆 💪 ⚙️ `from starlette.responses import Response` ⚖️ `from starlette.responses import JSONResponse`.

你也可以在直接返回`Response`时添加头部。

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。

Crea un response tal como se describe en [Retornar una respuesta directamente](response-directly.md){.internal-link target=_blank} y pasa los headers como un parámetro adicional:

```Python hl_lines="10-12"
{!../../docs_src/response_headers/tutorial001.py!}
```

/// note | Detalles Técnicos

También podrías utilizar `from starlette.responses import Response` o `from starlette.responses import JSONResponse`.

But you can return a `JSONResponse` directly from your *path operations*.

It might be useful, for example, to return custom headers or cookies.

## Return a `Response`

In fact, you can return any `Response` or any sub-class of it.

/// tip

`JSONResponse` itself is a sub-class of `Response`.

///

And when you return a `Response`, **FastAPI** will pass it directly.

Erstellen Sie eine Response wie in [Eine Response direkt zurückgeben](response-directly.md){.internal-link target=_blank} beschrieben und übergeben Sie die Header als zusätzlichen Parameter:

```Python hl_lines="10-12"
{!../../docs_src/response_headers/tutorial001.py!}
```

/// note | "Technische Details"

```Python hl_lines="10-12"
{!../../docs_src/response_headers/tutorial001.py!}
```

/// note | "Technical Details"

You could also use `from starlette.responses import Response` or `from starlette.responses import JSONResponse`.

### 更多信息

/// note | "技术细节"

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

为了方便开发者，**FastAPI** 封装了相同数据类型，如`starlette.responses` 和 `fastapi.responses`。不过大部分response对象都是直接引用自Starlette。

因为`Response`对象可以非常便捷的设置headers和cookies，所以 **FastAPI** 同时也封装了`fastapi.Response`。

///

	w.WriteHeader(statusCode)
	if response != nil {
		w.Write(response)
	}
}

// mimeType represents various MIME type used API responses.
type mimeType string

const (
	// Means no response type.
	mimeNone mimeType = ""
	// Means response type is JSON.
	mimeJSON mimeType = "application/json"
	// Means response type is XML.
