我正嘗試將圖像上傳到存儲桶。連接完成後,上傳顯然開始,但沒有進展。我認爲服務器上的權限是正確的,因爲Android應用程序能夠上傳。 在我的appdelegate我有這樣的:迅速上傳到s3存儲桶並未結束
let credentialsProvider = AWSCognitoCredentialsProvider(regionType: AWSRegionType.USEast1, identityPoolId: "us-east-1:XXXXXX-XXXX-XXXX-XXXX-XXXX」, unauthRoleArn: "arn:aws:iam::XXXXX:role/Cognito_mybucketUnauth_Role", authRoleArn: "arn:aws:iam::XXXXX:role/Cognito_mybucketAuth_Role", identityProviderManager: nil)
let configuration = AWSServiceConfiguration(region: AWSRegionType.USEast1, credentialsProvider: credentialsProvider)
AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration
而這款以獲取圖像,並上傳
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]){
//getting details of image
let uploadFileURL = info[UIImagePickerControllerReferenceURL] as! NSURL
let imageName = uploadFileURL.lastPathComponent
let documentDirectory = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first! as String
// getting local path
let localPath = (documentDirectory as NSString).stringByAppendingPathComponent(imageName!)
//getting actual image
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
let data = UIImagePNGRepresentation(image)
data!.writeToFile(localPath, atomically: true)
let imageData = NSData(contentsOfFile: localPath)!
imageURL = NSURL(fileURLWithPath: localPath)
CampoImagem.image = image
picker.dismissViewControllerAnimated(true, completion: nil)
uploadImage()
}
func uploadImage(){
//defining bucket and upload file name
let S3BucketName: String = 「mybucket"
let S3UploadKeyName: String = "profile/testImage.jpg"
let expression = AWSS3TransferUtilityUploadExpression()
/*expression.uploadProgress = {(task: AWSS3TransferUtilityTask, bytesSent: Int64, totalBytesSent: Int64, totalBytesExpectedToSend: Int64) in
dispatch_async(dispatch_get_main_queue(), {
let progress = Float(totalBytesSent)/Float(totalBytesExpectedToSend)
print("Progress is: \(progress)")
})
}*/
self.uploadCompletionHandler = { (task, error) -> Void in
dispatch_async(dispatch_get_main_queue(), {
if ((error) != nil){
print("Failed with error")
print("Error: \(error!)");
}
else{
print("Sucess")
}
})
}
let transferUtility = AWSS3TransferUtility.defaultS3TransferUtility()
transferUtility.uploadFile(imageURL, bucket: S3BucketName, key: S3UploadKeyName, contentType: "image/jpeg", expression: expression, completionHander: uploadCompletionHandler).continueWithBlock { (task) -> AnyObject! in
if let error = task.error {
print("Error: \(error.localizedDescription)")
}
if let exception = task.exception {
print("Exception: \(exception.description)")
}
if let _ = task.result {
print("Upload Starting!")
}
return nil;
}
}
打印:上傳開始!
我懷疑這是當ID和許可完成與aws上傳的東西,但我認爲如果這是上傳不會啓動,更正? 我該如何解決這個問題?
我實現了完全一樣的教程添加憑據檢查這個代碼,你也可以檢查。但是我的上傳速度爲42%,並且經過了很長時間的錯誤。 –
它使用演示代碼? –
