Swift.Streaming 来自 url 的音频，错误代码为 -999 "cancelled"

Question

这是我的代码:

var playering = AVPlayer()


private func streamAudio(url: String) {
    guard let url = URL(string: url) else {return}
    let playerItems = AVPlayerItem(url: url)
    ReportVC.playering = AVPlayer(playerItem: playerItems)
    ReportVC.playering.play()
}

我在 viewDidLoad() 方法中调用 streamAudio 是这样的:

self.streamAudio(url: "https://stage.careandcarers.com/file/get/0b710400-4454-4a46-9ed5-8a542f046ed8.m4a")

但我在控制台中收到此错误:

问题是什么？

尝试一下:

func streamPlay(streamUrl : string){
let playerItem = AVPlayerItem( url:NSURL( string: streamUrl )! as URL )
        player = AVPlayer(playerItem:playerItem)
        player!.rate = 1.0;
        //isplay is a bool variable that indicate your stream playing is in process or not(default value = false)
        if isPlay{

            player!.pause()
            //playDemo is button that you use to stream play
            playDemo!.setImage(UIImage(named: "playBtn"), for: UIControl.State.normal)
            playDemo!.setTitle("Pause", for: UIControl.State.normal)
            isPlay = false

        }else{

            player!.play()
            playDemo!.setImage(UIImage(named: "media_pause"), for: UIControl.State.normal)
            playDemo!.setTitle("play", for: UIControl.State.normal)
            isPlay = true
        }
}

在你的 viewDidLoad 中:

 let url = "https://stage.careandcarers.com/file/get/0b710400-4454-4a46-9ed5-8a542f046ed8.m4a"
 streamPlay(streamUrl : url)
