无法在 iOS 13 上将视频上传到 Firebase 存储

Question

在 iOS 12 上完美运行。

简单的样板代码：

let storageRef = storage.reference().child("\(profile.studioCode)/\(selected.classId)/\(uploadDate)")

        //Upload file and metadata
        let uploadTask = storageRef.putFile(from: videoURL, metadata: metadata)

        //Listen for state changes and, errors, and completion of the upload
        uploadTask.observe(.resume) { (snapshot) in
            //upload resumed or started
        }

        uploadTask.observe(.pause) { (snapshot) in
            //upload paused
        }

        uploadTask.observe(.progress) { (snapshot) in
            //upload progress
        }

        uploadTask.observe(.success) { (snapshot) in
            //upload successful
        }

        uploadTask.observe(.failure) { (snapshot) in
            //upload failed
        }

给我：

Error Domain=FIRStorageErrorDomain Code=-13000 "An unknown error occurred, please check the server response."

我已将 Cocoapods 和 Firebase 更新为最新版本，尝试允许任意加载，并尝试退出并重新登录应用程序以重置我的身份验证令牌。在 iOS 13 中，它会在上传时立即抛出该错误，但在 iOS 12 中，它上传得非常好。任何帮助或见解将不胜感激。谢谢！

Answer 1

我有一个类似的问题，但这里有一个简单的解决方法：您需要使用 '.putData' 而不是 '.putFile' 并在上传时指定 MIME 类型。

let metadata = StorageMetadata()
//specify MIME type
metadata.contentType = "video/quicktime"

//convert video url to data
if let videoData = NSData(contentsOf: videoURL) as Data? {
    //use 'putData' instead
    let uploadTask = storageRef.putData(videoData, metadata: metadata)
}

我是如何解决它的：

事实证明，iOS 13 和 iOS 12 中的文件路径不同：

iOS12路径：

file:///private/var/mobile/Containers/Data/Application/DF9C58AB-8DCE-401B-B0C9-2CCAC69DC0F9/tmp/12FD0C43-F9A0-4DCB-96C3-18ED83FED424.MOV

iOS13 路径：

file:///private/var/mobile/Containers/Data/PluginKitPlugin/5DFD037B-AC84-463B-84BD-D0C1BEC00E4C/tmp/trim.7C8C6CD1-97E7-44D4-9552-431D90B525EA

注意额外的“.” 在 iOS13 路径中。我的解决方案是，在我的 imagePickerController didFinishPickingMediaWithInfo 函数中，将文件复制到另一个临时目录，从那里上传，然后删除副本。

 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)
                let targetURL = tempDirectoryURL.appendingPathComponent(String(urlSlices[1])).appendingPathExtension(String(urlSlices[2]))

                //Copy the video over
                try FileManager.default.copyItem(at: videoURL, to: targetURL)

                picker.dismiss(animated: true) {
                    self.videoRecorded = false
                    self.showUpload(targetURL)
                }
            }
            else {
                //If on iOS12 just use the original URL
                picker.dismiss(animated: true) {
                    self.videoRecorded = false
                    self.showUpload(videoURL)
                }
            }
        }
        catch let error {
            //Handle errors
        }
