我的scala代码中的文件下载问题

import java.io.FileOutputStream
import java.net.URL
import scala.util.Try

object FileDownloader {
  def downloadFile(url: String, savePath: String): Try[Unit] = Try {
    val connection = new URL(url).openConnection()
    val inputStream = connection.getInputStream
    val outputStream = new FileOutputStream(savePath)
    val buffer = new Array[Byte](1024)
    var bytesRead = inputStream.read(buffer)
    while (bytesRead != -1) {
      outputStream.write(buffer, 0, bytesRead)
      bytesRead = inputStream.read(buffer)
    }
    outputStream.close()
    inputStream.close()
  }
}

// 使用示例
val url = "https://example.com/file.txt"
val savePath = "/path/to/save/file.txt"

FileDownloader.downloadFile(url, savePath) match {
  case scala.util.Success(_) => println("文件下载成功")
  case scala.util.Failure(exception) => println(s"文件下载失败: ${exception.getMessage}")
}
