Wenn Sie jedoch eine benutzerdefinierte Response-Klasse mit `None` als Medientyp angegeben haben, verwendet FastAPI `application/json` für jede zusätzliche Response, die über ein zugehöriges Modell verfügt.

///

## Informationen kombinieren { #combining-information }

But if you have specified a custom response class with `None` as its media type, FastAPI will use `application/json` for any additional response that has an associated model.

///

## Combining information { #combining-information }

You can also combine response information from multiple places, including the `response_model`, `status_code`, and `responses` parameters.

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

/// note | Detalles Técnicos de `async`

Cuando usas los métodos `async`, **FastAPI** ejecuta los métodos del archivo en un threadpool y los espera.

///

/// note | Detalles Técnicos de Starlette

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

在普通 `def` *路径操作函数*  内，则可以直接访问 `UploadFile.file`，例如：

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

/// note | `async` 技术细节

使用 `async` 方法时，**FastAPI** 在线程池中执行文件方法，并 `await` 操作完成。

///

/// note | Starlette 技术细节

**FastAPI** 的 `UploadFile` 直接继承自 **Starlette** 的 `UploadFile`，但添加了一些必要功能，使之与 **Pydantic** 及 FastAPI 的其它部件兼容。
