#### 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。

/// 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：

authors:...

    socketAdapters.find { it.matchesSocket(sslSocket) }?.getSelectedProtocol(sslSocket)

  override fun getStackTraceForCloseable(closer: String): Any? =
    if (Build.VERSION.SDK_INT >= 30) {
      CloseGuard().apply { open(closer) }
    } else {
      super.getStackTraceForCloseable(closer)
    }

  override fun logCloseableLeak(
    message: String,
    stackTrace: Any?,
  ) {
    if (Build.VERSION.SDK_INT >= 30) {

        return value!!
