[英]On Flutter iOS, I can't upload to Firebase Storage because of 400 errors
[英]Can't Upload Video to Firebase Storage on iOS 13
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 更新到最新版本,尝试允许任意加载,并尝试注销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!
我遇到了类似的问题,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)
}
事实证明,iOS 13 中的文件路径与 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.MOV
注意额外的“。” 在 iOS13 路径中。 我的解决方案是,在我的 imagePickerController didFinishPickingMediaWithInfo function 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
}
