ios – 将图像上传到S3无法完成上传

>启动uploadToS3()
>文件开始传输发送字节到服务器.
>当发送大约600,000个字节时,上载停止.
> 20-40秒后,应用程序继续上传进度为0％.它就好像文件传输从未开始.
>在整个时间内,记录器中不会出现任何错误.

在我的视图控制器中,我有以下方法上传文件.

func uploadToS3(){

    // get the image from a UIImageView that is displaying the SELEcted Image
    var img: UIImage = imageView.image!

    // create a local image that we can use to upload to s3
    var path: NSString = NstemporaryDirectory().StringByAppendingPathComponent("image.png")
    var imageData: NSData = UIImagePNGRepresentation(img)
    imageData.writeToFile(path as String,atomically: truE)

    // once the image is saved we can use the path to create a local fileurl
    var url:NSURL = NSURL(fileURLWithPath: path as String)!

    // next we set up the S3 upload request manager
    let uploadrequest = AWSS3TransfeRMANagerUploadrequest()
    // set the bucket
    uploadrequest?.bucket = "test-bucket"
    // I want this image to be public to anyone to view it so I'm setTing it to Public Read
    uploadrequest?.ACL = AWSS3ObjectCAnnedACl.PublicRead
    // set the image's name that will be used on the s3 server. I am also creaTing a folder to place the image in
    uploadrequest?.key = "foldername/image.png"
    // set the content type
    uploadrequest?.contentType = "image/png"
    // and finally set the body to the local file path
    uploadrequest?.body = url;

    // we will track progress through an AWSNetworkingUploadProgressBlock
    uploadrequest?.uploadProgress = {[uNowned self](bytesSent:Int64,@R_323_10586@lBytesSent:Int64,@R_323_10586@lBytesExpectedToSend:Int64) in

        dispatch_sync(dispatch_get_main_queue(),{ () -> Void in
            println("@R_323_10586@l  bytes sent")
            println(@R_323_10586@lBytesSent)

            println("@R_323_10586@l  bytes expected to send")
            println(@R_323_10586@lBytesExpectedToSend)
        })
    }

    // Now the upload request is set up we can creat the transfermanger,the credentials are already set up in the app delegate
    var transfeRMANager:AWSS3TransfeRMANager = AWSS3TransfeRMANager.defaultS3TransfeRMANager()
    // start the upload
    transfeRMANager.upload(uploadrequest).conTinueWithExecutor(BFExecutor.mainThreadExecutor(),withBlock:{ [uNowned self]
        task -> AnyObject in

        // once the uploadmanager finishes check if there were any errors
        if(task.error != nil){
            println("%@",task.error);
        }else{ // if there aren't any then the image is uploaded!
            // this is the url of the image we just uploaded
            println("https://s3.amazonaws.com/s3-demo-swift/foldername/image.png");
        }

        //self.removeLoadingView()
        println("all done");
        return ""
        })
}

对于任何想要重新创建此应用程序的人

添加到您的Podfile：

pod 'AWscore'
pod 'AWSS3'
pod 'AWSiOSSDKv2'
pod 'AWSCognitoSync'

然后添加包含以下内容的桥接头

#import <AWscore/AWscore.h>
#import <AWSS3/AWSS3.h>

在我的AppDelegate中,我有：

func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {        
    // Override point for customization after application launch.
    AWSCognitoCredentialsProvider.initialize()

    var credentialsProvider = AWSCognitoCredentialsProvider(
        regionType: AWSRegionType.USEast1,identityPoolId: "identity pool id"
    )

    var configuration = AWSserviceConfiguration(
        region: AWSRegionType.USEast1,credentialsProvider: credentialsProvider
    )

    AWSserviceManager.defaultserviceManager().defaultserviceConfiguration = configuration

    return true
}

最后,在包含uploadToS3()的视图控制器中,添加import AWSS3.

更新

这是记录错误的最后一部分.

我的问题是,如何解决这个问题并成功上传图片.
