我想在亚马逊服务器上上传一张图片，但每次我试图上传一张图片时，它都会在日志中显示一个错误。

这是我用来上传图片的代码。

func fusumaImageSelected(image: UIImage) {
    self.imageView.image = image


    let fileName = NSProcessInfo.processInfo().globallyUniqueString.stringByAppendingString(".jpg")
    let fileURL = NSURL(fileURLWithPath: NSTemporaryDirectory()).URLByAppendingPathComponent("upload").URLByAppendingPathComponent(fileName)
    let filePath = fileURL.path!
    let imageData = UIImageJPEGRepresentation(image, 0.5)
    imageData!.writeToFile(filePath, atomically: true)



    let putObjectRequest = AWSS3PutObjectRequest()
    putObjectRequest.body = imageData
    putObjectRequest.contentLength = NSNumber.init(long: (imageData?.length)!)
    putObjectRequest.expires = NSDate().dateByAddingTimeInterval(3600);
    putObjectRequest.contentType = "image/png"
    putObjectRequest.key = "production/uploads/avatars/200/avatar.jpg"
    putObjectRequest.bucket = Constants.S3BucketName

    self.uploadProgessInLoading(putObjectRequest)
    AWSS3.defaultS3().putObject(putObjectRequest).continueWithBlock{(task) -> AnyObject! in

        if let error = task.error {
            if error.domain == AWSS3TransferManagerErrorDomain as String {
                if let errorCode = AWSS3TransferManagerErrorType(rawValue: error.code) {
                    switch (errorCode) {
                    case .Cancelled, .Paused:
                        dispatch_async(dispatch_get_main_queue(), { () -> Void in

                        })
                        break;

                    default:
                        print("upload() failed: [\(error)]")
                        break;
                    }
                } else {
                    print("upload() failed: [\(error)]")
                }
            } else {
                print("upload() failed: [\(error)]")
            }
        }

        if let exception = task.exception {
            print("upload() failed: [\(exception)]")
        }

        if task.result != nil {

        }
        return nil
    }
}
