/// note | Nota

Note que você deve retornar a imagem utilizando um `FileResponse` diretamente.

/// info | Informação

```Python
contents = await myfile.read()
```

若是在一般的 `def` 路徑操作函式中，你可以直接存取 `UploadFile.file`，例如：

```Python
contents = myfile.file.read()
```

/// note | `async` 技術細節

當你使用這些 `async` 方法時，**FastAPI** 會在執行緒池中執行對應的檔案方法並等待結果。

///

/// note | Starlette 技術細節

**FastAPI** 的 `UploadFile` 直接繼承自 **Starlette** 的 `UploadFile`，但新增了一些必要部分，使其與 **Pydantic** 及 FastAPI 其他部分相容。

すでに格納されている属性`"tax": 20.2`を含まないため、入力モデルは`"tax": 10.5`のデフォルト値を取ります。

そして、データはその「新しい」`10.5`の`tax`と共に保存されます。

## `PATCH`による部分的な更新 { #partial-updates-with-patch }

また、[HTTPの`PATCH`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH)操作でデータを*部分的に*更新することもできます。

つまり、更新したいデータだけを送信して、残りはそのままにしておくことができます。

/// note | 備考

`PATCH`は`PUT`よりもあまり使われておらず、知られていません。
