Question

为什么Xcode会向我抱怨有关将图像上传到Firebase存储的权限的任何原因，但是当我在模拟器中运行相同的应用程序时，它可以正常工作吗？

权限错误：

无法访问正文文件：/var/mobile/Media/DCIM/100APPLE/IMG_0974.JPG 错误域= NSCocoaErrorDomain代码= 257“文件”IMG_0974.JPG“ 因为你没有权限查看它而无法打开。“ 的UserInfo = {NSURL =文件：///var/mobile/Media/DCIM/100APPLE/IMG_0974.JPG， NSFilePath =在/ var /移动/媒体/ DCIM / 100APPLE / IMG_0974.JPG， NSUnderlyingError = 0x14805d680 {错误域= NSPOSIXErrorDomain代码= 1 “不允许操作”}}

我现在遇到同样的问题。上传在模拟器中工作正常，但在设备上它给我权限错误。我的解决方法是将图像上传为数据而不是文件的URL：

let imageData = UIImageJPEGRepresentation(image, 1.0)
let uploadTask = storageReference.child(remoteFilePath).putData(imageData, metadata: metadata, completion: { (metadata, error) in
    // Your code here
}

上传在模拟器中工作正常，但在设备上它给了我权限错误。将图像上传为数据而不是文件的URL：

首先声明

    fileprivate lazy var storageRef: StorageReference = Storage.storage().reference(forURL: "gs://yourAPP.appspot.com/")

然后

     let path : String = "\(String(describing: Auth.auth().currentUser?.uid))/\(Int(Date.timeIntervalSinceReferenceDate * 1000))/\(photoReference)"

                // 6

                let imageData = UIImageJPEGRepresentation(photoReference, 0.1)
                let uploadTask = self.storageRef.child(path).putData(imageData!, metadata: nil, completion: { (metadata, error) in
                    // Your code here
                    if let error = error {
                        print("Error uploading photo: \(error.localizedDescription)")
                        return
                    }

                    // 7
                    self.setImageURL(self.storageRef.child((metadata?.path)!).description, forPhotoMessageWithKey: key)
                })

谢谢你，还有亚历克斯和所有回答这个问题的人...... 我试过这个...下面这段代码在didFinishPickingMediaWithInfo中...... 我评论了当用户从photoLibrary中选择图像时处理的代码，并且再次感谢你，所以我的代码是（下面）

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    picker.dismissViewControllerAnimated(true,completion:nil)
    let image = info[UIImagePickerControllerOriginalImage] as! UIImage//<--

    let imageData = UIImageJPEGRepresentation(image, 1.0)
    let imagePath = "photos/xxxyyyzzz.jpg"//whatever you want
    let metadata = FIRStorageMetadata()
    metadata.contentType = "image/jpeg"

    storageRef.child(imagePath).putData(imageData!,metadata:metadata){
                (metadata, error) in
                if let error = error{
                    print("Error uploading photo: \(error)")
                }
                else{
                    //if there is no error the compiler will come here
                    print("no error")
                    //and maybe you want to use the full url or download url after success
                    //for example you wanna have tha downloadURL...
                    let downloadURL = metadata!.downloadURL()
                    print("\(downloadURL)")
                    //do whatever you want...
                }
    }

}

另一种选择是将文件复制到“documents”目录（可写）。它使用了比UIImageJPEGRepresentation方法更多的代码，因此您可能仍然更喜欢使用该技术。如果您真的不想改变原始图像，也许使用“文档目录”方法（但是，理论上，原始图像与使用asset.requestContentEditingInput(with: options, completionHandler: {(contentEditingInput: PHContentEditingInput?, info: [AnyHashable : Any]) -> Void in let originalFileUrl = contentEditingInput!.fullSizeImageURL! /* Copy file from photos app to documents directory */ let fileManager = FileManager.default let documentsDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString let destinationPath = documentsDirectory.appendingPathComponent(originalFileUrl.lastPathComponent) let destinationUrl = URL(fileURLWithPath: destinationPath) do { try fileManager.copyItem(at: originalFileUrl, to: destinationUrl) } catch { print("Unable to copy file from photos to documents directory (run out of space on device?)") return } /* Create metadata etc. for Firebase... */ /* Upload file to Firebase */ fileRef.putFile(from: destinationUrl, metadata: metadata, completion: { (metadata, error) in // Remove the file from the documents directory do { try fileManager.removeItem(at: destinationUrl) } catch { print("Unable to remove file from documents directory") } }) })创建的图像之间的差异应该是不可察觉的）。

查看Firebase存储规则。和临时允许所有路径没有auth。
