如何播放下载的音频文件 swift

Question

我有 2 个音频文件变体，第一个是嵌入的，第二个是我从服务器下载的。
第一个 varian 运行良好。但是当我从服务器获取音频文件时没有播放并且出现错误。

我得到路径：

file:///var/mobile/Containers/Data/Application/24656EA9-6F1F-4C0F-A6FE-5D457908A80D/Documents/Dumont.mp3

并尝试玩

func playMusic(filename: String) {
    let url = NSBundle.mainBundle().URLForResource(filename, withExtension: "mp3")
    guard let newURL = url else {
        print("Could not find file: \(filename)")
        return
    }
    do {
        player = try AVAudioPlayer(contentsOfURL: newURL)
        player!.numberOfLoops = -1
        player!.prepareToPlay()
        player!.play()
    } catch let error as NSError {
        print(error.description)
    }
}

如何在 swift 2.3 中播放此音频文件？

嗨，给你投反对票的蠢货们：

if let dir = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
  let path = NSURL(fileURLWithPath: dir).URLByAppendingPathComponent("Dumont.mp3")
    do {
        player = try AVAudioPlayer(contentsOfURL: path)
        player!.numberOfLoops = -1
        player!.prepareToPlay()
        player!.play()
      } catch let error as NSError {
         print(error.description)
      }

此代码播放下载的歌曲！
