如何在AVPlayer swift中检测错误链接播放

guard let url = URL(string: "your_video_url") else { return }
let player = AVPlayer(url: url)

player.addObserver(self, forKeyPath: "status", options: .new, context: nil)
player.addObserver(self, forKeyPath: "error", options: .new, context: nil)

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
    if keyPath == "status" {
        if player.status == .failed {
            // 处理播放失败的情况
            print("播放失败")
        }
    } else if keyPath == "error" {
        if let error = player.error {
            // 处理错误信息
            print("播放错误: \(error.localizedDescription)")
        }
    }
}

player.removeObserver(self, forKeyPath: "status")
player.removeObserver(self, forKeyPath: "error")
