# Файлы и формы в запросе

Вы можете определять файлы и поля формы одновременно, используя `File` и `Form`.

/// info | Дополнительная информация

Чтобы получать загруженные файлы и/или данные форм, сначала установите <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Например: `pip install python-multipart`.

///

## Импортируйте `File` и `Form`

            bb.putShort((short) 0);
            bb.putShort((short) 0);

            Referral ref = new Referral();
            ref.decode(testBuffer, 0, testBuffer.length);

            assertEquals(serverType, ref.getServerType());
            assertEquals(proximity, ref.getProximity());
            assertEquals(ttl, ref.getTtl());
        }
    }

# Form Models { #form-models }

You can use **Pydantic models** to declare **form fields** in FastAPI.

/// info

To use forms, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
```

Tất cả các tham số này có thể khác với `static`, điều chỉnh chúng với phù hợp với ứng dụng của bạn.

## Thông tin thêm

# Body - Updates { #body-updates }

## Update replacing with `PUT` { #update-replacing-with-put }

To update an item you can use the <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a> operation.

You can use the `jsonable_encoder` to convert the input data to data that can be stored as JSON (e.g. with a NoSQL database). For example, converting `datetime` to `str`.

### 編寫自己的非同步程式碼

Starlette （和 **FastAPI**） 是基於 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> 實作的，這使得它們與 Python 標準函式庫相容 <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> 和 <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>。
