Can't play mp3 file over HTTP via AVPlayer

问题:

I'm trying to play MP3 file via AVPlayer:

let url = URL(string: "http://transom.org/wp-content/uploads/2004/03/stereo_40kbps.mp3?_=7")!
let asset = AVURLAsset(url: url)
let item = AVPlayerItem(asset: asset)
let player = AVPlayer(playerItem: item)
player.play()

But I'm getting the next log:

2017-09-26 21:57:07.906598+0300 MyApp[7558:1177816] CredStore - performQuery - Error copying matching creds.  Error=-25300, query={
    class = inet;
    "m_Limit" = "m_LimitAll";
    "r_Attributes" = 1;
    sync = syna;
}

I guess it's because of iOS 11 and Xcode 9, but I have no idea how to solve this problem.

回答1:

The problem seems to be with the App Transport security, after enabling it, it worked fine with the following sets of code in iOS 11,
Also the above URL that you have provided seems to have associated https link, please use either https link or allow App Transport security

let avPlayerVC = AVPlayerViewController()
        let url = URL(string: "https://transom.org/wp-content/uploads/2004/03/stereo_40kbps.mp3?_=7")!
        let asset = AVURLAsset(url: url)
        let item = AVPlayerItem(asset: asset)
        let player = AVPlayer(playerItem: item)
        avPlayerVC.player = player

        present(avPlayerVC, animated: true) {
            player.play()
        }

But here I have used AVPlayerViewController and used the same instance of AVPlayer as you used in your code.
I don't know how you are using the AVPlayer in your case, but the above case worked fine.

回答2:

same error.
I've solved with server-side work.
remove HSTS header "Strict-Transport-Security: max-age=31536000" from http response, disappear error and work fine. I don't know the cause..
request : https://abc.../aaaa.mp3

回答3:

I've faced the same issue, we've tried to set all the headers on server side to inactive/active

Finally unset range was set to inactive and then it worked.
