#### 对类似文件的对象使用 `StreamingResponse`

如果您有类似文件的对象（例如，由 `open()` 返回的对象），则可以在 `StreamingResponse` 中将其返回。

包括许多与云存储，视频处理等交互的库。

```Python hl_lines="2  10-12  14"
{!../../docs_src/custom_response/tutorial008.py!}
```

/// 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。
