ios - 将视频上传到 Firebase 存储（未知错误）

问题描述

我想要做的：从我的图像选择器中获取一个视频并将其上传到 Firebase 存储，并在我的 Firestore 中创建一个指向它的文档。

当前的问题是什么： Xcode 向我抛出了一个未知错误。无法将视频上传到存储。（下面的控制台响应）

我的代码：

if self.fireImage == nil, description == "", self.fireURL != nil{
                                
    print(self.fireURL!)
    storageVideoRef.putFile(from: self.fireURL! as URL, metadata: nil) { (storageMetaData, error) in
    if error != nil{
        print(error!.localizedDescription)
        return
        }
        print("is in database")
            storageVideoRef.downloadURL { (url, error) in
            if let metaVideoUrl = url?.absoluteString{
                                            
            docRef.getDocument { (doc, err) in
                if let doc = doc, doc.exists{
                print("Post ID already taken")
                }else{
                                                    
                print("Post gets created")
                                                
                self.db.collection("posts").document(combined).setData([
                    "hasLiked": [],
                    "likes": self.likes,
                    "video": metaVideoUrl,
                    "postType": 6,
                    "profileImage": pfp!,
                    "time": date,
                    "uid": self.userID,
                    "username": fullname!,
                    "postID": combined,
                                                
                    ]) { err in
                    if let err = err {
                        print("Error writing document: \(err)")
                    } else {
                        print("Post Document successfully written!")
                            }
                        }
                    }
                }
            }
        }
    }
}

解决方案

看起来这是一个 iOS 13 问题，其中文件路径与所有其他版本略有不同。

我通过检查上传设备是否在 iOS 13 上解决了这个问题，然后更改了文件路径以使其正常工作。

这是代码：

else if let videoURL = info[.mediaURL] as? URL {
            fireURL = videoURL
            
            do {
                if #available(iOS 13, *) {
                    //If on iOS13 slice the URL to get the name of the file
                    let urlString = videoURL.relativeString
                    let urlSlices = urlString.split(separator: ".")
                    //Create a temp directory using the file name
                    let tempDirectoryURL = URL(fileURLWithPath: NSTemporaryDirectory(), isDirectory: true)
                    fireURL = tempDirectoryURL.appendingPathComponent(String(urlSlices[1])).appendingPathExtension(String(urlSlices[2]))

                    //Copy the video over
                    try FileManager.default.copyItem(at: videoURL, to: fireURL!)
                }
            }
            catch let error {
                print(error.localizedDescription)
            }
