/// tip | "小贴士"

注意在这里，因为我们使用的是不支持 `async` 和 `await` 的标准 `open()`，我们使用普通的 `def` 声明了路径操作。

///

### `FileResponse`

异步传输文件作为响应。

与其他响应类型相比，接受不同的参数集进行实例化：

* `path` - 要流式传输的文件的文件路径。
* `headers` - 任何自定义响应头，传入字典类型。

|:-------------------------------------------|:------------------------------------------------------------|
| `minio_node_iam_last_sync_duration_millis` | Last successful IAM data sync duration in milliseconds.     |
| `minio_node_iam_since_last_sync_millis`    | Time (in milliseconds) since last successful IAM data sync. |
| `minio_node_iam_sync_failures`             | Number of failed IAM data syncs since server start.         |

これにはクラウドストレージとの連携や映像処理など、多くのライブラリが含まれています。

```

/// tip | "豆知識"

ここでは `async` や `await` をサポートしていない標準の `open()` を使っているので、通常の `def` でpath operationを宣言していることに注意してください。

///

### `FileResponse`

レスポンスとしてファイルを非同期的にストリームします。

他のレスポンスタイプとは異なる引数のセットを受け取りインスタンス化します。
