如何在swift 4中成功地流式传输远程mp3文件？

import AVFoundation

func streamRemoteMP3File(url: URL) {
    let playerItem = AVPlayerItem(url: url)
    let player = AVPlayer(playerItem: playerItem)
    player.play()
}

import AVFoundation

func streamRemoteMP3File(url: URL) {
    let tempURL = FileManager.default.temporaryDirectory.appendingPathComponent("temp.mp3")
    
    let downloadTask = URLSession.shared.downloadTask(with: url) { (location, response, error) in
        guard let location = location else {
            print("Failed to download MP3 file:", error?.localizedDescription ?? "")
            return
        }
        
        do {
            try FileManager.default.moveItem(at: location, to: tempURL)
            let playerItem = AVPlayerItem(url: tempURL)
            let player = AVPlayer(playerItem: playerItem)
            player.play()
        } catch {
            print("Failed to move downloaded file:", error.localizedDescription)
        }
    }
    
    downloadTask.resume()
}
