Question

我试图（1）从链接下载一段音频，（2）将新下载的音频添加到AVPlayer并（3）播放它。在步骤（3）出现问题，我正在寻找任何指导。这是代码，包括我的alamofire和下载功能，因为我担心在那个阶段可能会出现问题。

import AVFoundation

class SettingAlarmViewController: UIViewController {

var player:AVPlayer!

override func viewDidLoad() {
    super.viewDidLoad()
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    }
    catch {
        // report for an error
    }
}

func getLatestPodcastURL(completion: @escaping (URL) -> ()) {

    let RSSUrl: String = "https://www.npr.org/rss/podcast.php?id=510318"

    Alamofire.request(RSSUrl).responseRSS() {response in
        if let podcastURL: String = response.result.value?.items[0].enclosure! 
       {
            let audioURL = URL(string: podcastURL)
            completion(audioURL!)
        }
        else {
            //error handling
        }
    }
}

func downloadSongAsynch(audioUrl: URL, completion: @escaping (URL) -> ()) {
    let fileManager = FileManager.default
    let documentsDirectoryURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first!.appendingPathComponent("podcasts/")

    do {
        try fileManager.createDirectory(atPath: documentsDirectoryURL.path,
                                        withIntermediateDirectories: true, attributes: nil)
    } catch {
    //error handling
    }

    let destinationUrl = documentsDirectoryURL.appendingPathComponent(audioUrl.lastPathComponent)

    URLSession.shared.downloadTask(with: audioUrl, completionHandler: { (location, response, error) -> Void in
        guard let location = location, error == nil else { return }
        do {
            try FileManager.default.moveItem(at: location, to: destinationUrl)
        } catch {
            //error handling
        }
    }).resume()
    completion(destinationUrl)
}

@IBAction func SetUpBotton(_ sender: Any) {
    getLatestPodcastURL() {response in
            //Uses an asynchronous call to Alamofire to get the podcast URL
            self.downloadPodcastAsynch(audioUrl: response){response2 in
                self.player = AVPlayer(url: response2)
                print(self.player.currentItem)
            }

@IBAction func PlayButton(_ sender: Any) {
    player.play()
    print(player.currentItem)
}

日志始终显示我当前的项目：＆gt;

但没有任何戏剧。我已经通过尝试使用URL来传输此内容来检查音频是否正常工作。这很好。我得到以下内容：

BoringSSL错误＆＃34; [BoringSSL]函数boringssl_session_errorlog：第2871行[boringssl_session_read] SSL_ERROR_ZERO_RETURN（6）：操作失败，因为连接已通过close_notify警报干净地关闭

但是从我所读过的内容来看，这只是最新更新中的一个错误，不应该影响下载。有什么想法吗？

带有下载内容的AVPlayer不起作用，但流媒体内容不起作用
