我试图上传视频到谷歌的云存储，但遇到了一个错误:
BackgroundSession <1EE0DA45-0AA5-45FB-AAB4-1580A53F88A8> error requesting a NSURLSessionUploadTask from background transfer daemon: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service on pid 27172 named com.apple.nsurlsessiond was interrupted, but the message was sent over an additional proxy and therefore this proxy has become invalid."

这是我的相关Swift代码:
func timelapsePopup() {
let imagePC = UIImagePickerController()
imagePC.sourceType = .photoLibrary
imagePC.delegate = self
imagePC.sourceType = .savedPhotosAlbum
imagePC.mediaTypes = [String(kUTTypeMovie)]
imagePC.allowsEditing = false
V.timelapse = true
present(imagePC, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if V.timelapse == true { //TIMELAPSE
V.timelapse = false
if let selectedVideo = info[UIImagePickerController.InfoKey.mediaURL] as? URL {
// fatalError("Expected a dictionary containing an image, but was provided the following: (info)")
print("Here's the file URL: ", selectedVideo)
dismiss(animated: true, completion: nil)
brain.submitEvidence(itemIndex: V.indexToBePassed, image: UIImage(), timelapsePath: selectedVideo)
}
myTableView.reloadData()
}
mutating func submitEvidence(itemIndex: Int, image: UIImage, timelapsePath: URL) {
print(timelapsePath.absoluteString)
if timelapsePath.absoluteString != "" {
let item = V.items[itemIndex]
item.timelapseURL = timelapsePath
item.timeSubmitted = getCurrentTime()
item.sentForConfirmation = true
self.saveItem(item: item)
self.addTimelapseToFirestore(item: item)
} else {
let item = V.items[itemIndex]
item.image = image.toString()!
item.timeSubmitted = getCurrentTime()
item.sentForConfirmation = true
self.saveItem(item: item)
self.addToFirestore(item: item)
}
}
func addTimelapseToFirestore(item: Item) {
let storage = Storage.storage()
let data = Data()
let storageRef = storage.reference()
let localFile = item.timelapseURL
let photoRef = storageRef.child("videoOne")
let uploadTask = photoRef.putFile(from: localFile!, metadata: nil) { (metadata, error) in
guard let metadata = metadata else {
print(error?.localizedDescription)
return
}
print("video uploaded")
}
}
奇怪的是，它可以在上传图像时工作。例如，如果我将kUTypeMovie更改为kuttypeimage，以及其他一些使图像工作的东西，它会很好地将其上传到云存储。当我切换回视频时，它失败了。
非常感谢所有的帮助-让我知道，如果有任何其他的信息你需要!
欢呼,Josh
请使用以下代码，使用UIImagePicker对象类来选择设备中的视频或图像并将其上传到Firebase(我在您的代码中做了一些更改):
@IBAction func uploadButton(_ sender: Any) {
// Configuration
let picker = UIImagePickerController()
picker.allowsEditing = true
picker.delegate = self
picker.mediaTypes = [kUTTypeImage as String, kUTTypeMovie as String]
// Present the UIImagePicker Controller
present(picker, animated: true, completion: nil)
}
// The didFinishPickingMediaWithInfo let's you select an image/video and let's you decide what to do with it.
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if V.timelapse == true { //TIMELAPSE
V.timelapse = false
if let selectedVideo = info[UIImagePickerControllerMediaURL] as? NSURL {
// fatalError("Expected a dictionary containing an image, but was provided the following: (info)")
print("Here's the file URL: ", selectedVideo)
dismiss(animated: true, completion: nil)
brain.submitEvidence(itemIndex: V.indexToBePassed, image: UIImage(), timelapsePath: selectedVideo)
}
myTableView.reloadData()
}
mutating func submitEvidence(itemIndex: Int, image: UIImage, timelapsePath: URL) {
print(timelapsePath.absoluteString)
if timelapsePath.absoluteString != "" {
let item = V.items[itemIndex]
item.timelapseURL = timelapsePath
item.timeSubmitted = getCurrentTime()
item.sentForConfirmation = true
self.saveItem(item: item)
self.addTimelapseToFirestore(item: item)
} else {
let item = V.items[itemIndex]
item.image = image.toString()!
item.timeSubmitted = getCurrentTime()
item.sentForConfirmation = true
self.saveItem(item: item)
self.addToFirestore(item: item)
}
}
func addTimelapseToFirestore(item: Item) {
let storage = Storage.storage()
let data = Data()
let storageRef = storage.reference()
let localFile = item.timelapseURL
let photoRef = storageRef.child("videoOne.mov")
let uploadTask = photoRef.putFile(from: localFile!, metadata: nil) { (metadata, error) in
guard let metadata = metadata else {
print(error?.localizedDescription)
return
}
print("video uploaded")
}
}
请让我知道它是否适合你。
