问题描述
尝试下载.m3u8视频文件( http://devimages. apple.com/iphone/samples/bipbop/bipbopall.m3u8 )使用AVAssetDownloadURLSession.当我在Xcode中运行代码时,出现错误:
Trying to download a .m3u8 video file (http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8) using AVAssetDownloadURLSession. When i run the code in Xcode, I get an error:
错误域= AVFoundationErrorDomain代码= -11800 \"操作 无法完成\"UserInfo = {NSLocalizedFailureReason =未知 错误发生(-12780),NSLocalizedDescription =该操作可能 尚未完成}"
"Error Domain=AVFoundationErrorDomain Code=-11800 \"The operation could not be completed\" UserInfo={NSLocalizedFailureReason=An unknown error occurred (-12780), NSLocalizedDescription=The operation could not be completed}"
.我使用的代码:
import UIKit
import AVFoundation
class ViewController: UIViewController, AVAssetDownloadDelegate {
override func viewDidLoad() {
super.viewDidLoad()
self.setupAssetDownload()
// Do any additional setup after loading the view, typically from a nib.
}
func setupAssetDownload() {
// Create new background session configuration.
let configuration = URLSessionConfiguration.background(withIdentifier: "AssetID")
// Create a new AVAssetDownloadURLSession with background configuration, delegate, and queue
let downloadSession = AVAssetDownloadURLSession(configuration: configuration,
assetDownloadDelegate: self,
delegateQueue: OperationQueue.main)
let url = URL(string: "http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8")
// let url = URL(string: "https://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/sl.m3u8")
let asset = AVURLAsset(url: url!)
// Create new AVAssetDownloadTask for the desired asset
let downloadTask = downloadSession.makeAssetDownloadTask(asset: asset,
assetTitle: "AssetTitle",
assetArtworkData: nil,
options: nil)
// Start task and begin download
downloadTask?.resume()
}
//MARK: Delegates
public func urlSession(_ session: URLSession, assetDownloadTask: AVAssetDownloadTask, didFinishDownloadingTo location: URL){
print("DownloadedLocation:\(location.absoluteString)")
}
public func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) {
print("Error")
}
public func urlSession(_ session: URLSession, didBecomeInvalidWithError error: Error?) {
print("Error")
}
public func urlSession(_ session: URLSession, taskIsWaitingForConnectivity task: URLSessionTask) {
print("Waiting")
}
public func urlSession(_ session: URLSession, task: URLSessionTask, didFinishCollecting metrics: URLSessionTaskMetrics) {
print("Finihs collecting metrics:")
}
}

推荐答案
我检查了您的代码,发现您没有将 NSAllowsArbitraryLoads 键添加到下的 YES 您的. plist文件
I checked your code and found that you missed to add NSAllowsArbitraryLoads key to YES under NSAppTransportSecurity dictionary in your .plist file
