You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
    FileResponse,
    HTMLResponse,
    JSONResponse,
    ORJSONResponse,
    PlainTextResponse,
    RedirectResponse,
    Response,
    StreamingResponse,
    UJSONResponse,
)
```

## FastAPI Responses

from typing import List

from fastapi import FastAPI, File, UploadFile
from fastapi.responses import HTMLResponse

app = FastAPI()


@app.post("/files/")
async def create_files(
    files: List[bytes] = File(description="Multiple files as bytes"),
):
    return {"file_sizes": [len(file) for file in files]}


@app.post("/uploadfiles/")
async def create_upload_files(

from typing import List

from fastapi import FastAPI, File, UploadFile
from fastapi.responses import HTMLResponse
from typing_extensions import Annotated

app = FastAPI()


@app.post("/files/")
async def create_files(
    files: Annotated[List[bytes], File(description="Multiple files as bytes")],
):
    return {"file_sizes": [len(file) for file in files]}


@app.post("/uploadfiles/")
async def create_upload_files(

    并且在 OpenAPI 文档中也会这样记录。

!!! tip "小贴士"
    `ORJSONResponse` 目前只在 FastAPI 中可用，而在 Starlette 中不可用。



## HTML 响应

使用 `HTMLResponse` 来从 **FastAPI** 中直接返回一个 HTML 响应。

* 导入 `HTMLResponse`。
* 将 `HTMLResponse` 作为你的 *路径操作* 的 `response_class` 参数传入。

```Python hl_lines="2 7"
{!../../../docs_src/custom_response/tutorial002.py!}
```
