在将视频上传到firebase

Question

我将视频上传到Firebase时会遇到“未能发出沙箱扩展”错误。我的图像上传正好很好，只有videos会引起问题。

func testUploadLocalVideo() {
        if let localVideoURL = Bundle.main.url(forResource: "IMG_3787", withExtension: "MOV") {
            print("Attempting to upload local video: \(localVideoURL)")
            uploadVideoToFirebase(fileURL: localVideoURL)
        } else {
            print("❌ Local test video not found.")
        }
    }
    
func uploadImageToFirebase(image: UIImage) {
    let storageRef = Storage.storage().reference()
    guard let imageData = image.jpegData(compressionQuality: 0.75) else {
        print("Error converting image to data")
        return
    }
    
    let fileName = UUID().uuidString + ".jpg"
    let imageRef = storageRef.child("images/\(fileName)")
    
    imageRef.putData(imageData, metadata: nil) { metadata, error in
        if let error = error {
            print("Error uploading image: \(error.localizedDescription)")
            return
        }
        imageRef.downloadURL { url, error in
            if let error = error {
                print("Error getting download URL: \(error.localizedDescription)")
                return
            }
            if let downloadURL = url {
                DispatchQueue.main.async {
                    self.selectedImages.append(image)
                    self.isMediaSelected = true
                }
                print("✅ Image uploaded successfully: \(downloadURL)")
            }
        }
    }
}

func uploadVideoToFirebase(fileURL: URL) {
    print("Starting video upload with fileURL: \(fileURL)")
    
    // Create a temporary file URL within your app's sandbox
    let tempFileURL = FileManager.default.temporaryDirectory.appendingPathComponent(fileURL.lastPathComponent)
    
    do {
        // Copy the video file to the temporary location
        try FileManager.default.copyItem(at: fileURL, to: tempFileURL)
        print("✅ Video copied to temporary location: \(tempFileURL)")
        
        // Upload the video from the temporary location
        uploadVideoFromTempFile(tempFileURL: tempFileURL)
    } catch {
        print("❌ Error copying video file: \(error)")
    }
}

func uploadVideoFromTempFile(tempFileURL: URL) {
    // 1. Generate a unique filename using UUID
    let fileName = UUID().uuidString + ".mov"
    
    // 2. Create a reference to the video file in Firebase Storage
    let storageRef = Storage.storage().reference().child("videos/\(fileName)")
    
    // 3. Create a metadata object to store the video's content type
    let metadata = StorageMetadata()
    metadata.contentType = "video/quicktime"
    
    // 4. Load video data
    guard let videoData = try? Data(contentsOf: tempFileURL) else {
        print("❌ Unable to create video data from temporary file")
        return
    }
    
    // 5. Upload the video data directly using putData
    storageRef.putData(videoData, metadata: metadata) { metadata, error in
        if let error = error {
            print("❌ Error uploading video: \(error.localizedDescription)")
        } else {
            // Get download URL from the storage reference
            storageRef.downloadURL { url, error in
                if let downloadURL = url?.absoluteString {
                    DispatchQueue.main.async {
                        self.selectedVideos.append(tempFileURL) // Store tempFileURL
                        self.isMediaSelected = true
                    }
                    print("✅ Video uploaded successfully: \(downloadURL)")
                } else {
                    print("Video uploaded successfully, but download URL is not available.")
                }
            }
        }
    }
}

尽管尝试了各种解决方案，例如处理安全性的URL并将视频复制到临时位置，但错误仍然存在。这表明可能还有其他因素正在发挥作用，例如丢失的权利，并发问题，内存压力，Firebase SDK的问题，特定于设备的限制或干扰代码。也许我没有做任何正确的步骤（因为它没有起作用）。我的目标是使视频像图像一样上传到燃料库。
