Por ejemplo, dentro de una *path operation function* `async` puedes obtener los contenidos con:

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

Si estás dentro de una *path operation function* normal `def`, puedes acceder al `UploadFile.file` directamente, por ejemplo:

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

/// note | Detalles Técnicos de `async`

* `close()`：关闭文件。

因为上述方法都是 `async` 方法，要搭配「await」使用。

例如，在 `async` *路径操作函数* 内，要用以下方式读取文件内容：

```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。
