Amazon s3 图片上传（cognito id null）

Question

图像未在 amazon s3 中上传。我使用的是旧库，所有上传工作正常，但对于 ios 8，我使用新的 sdk 并创建新的 conginito id 现在我面临错误。任何帮助将不胜感激 我的代码是

  AWSS3TransferManagerUploadRequest *request = [[AWSS3TransferManagerUploadRequest alloc] init];






    request.bucket = @"my bucket name";
    request.key = @"my cognitio id";
    request.body =[NSURL fileURLWithPath:path];
    request.contentType = @"image/png";


    [[transferManager upload:request] continueWithExecutor:[BFExecutor mainThreadExecutor]
                                                 withBlock:^id(BFTask *task) {
                                                     NSLog(@"ckmdkcd dvdsv");
                                                     if (task.error) {
                                                         if ([task.error.domain isEqualToString:AWSS3TransferManagerErrorDomain]) {
                                                             switch (task.error.code) {
                                                                 case AWSS3TransferManagerErrorCancelled:
                                                                 case AWSS3TransferManagerErrorPaused:
                                                                     break;

                                                                 default:
                                                                     NSLog(@"Error: %@", task.error);
                                                                     break;
                                                             }
                                                         } else {
                                                             // Unknown error.
                                                             NSLog(@"Error: %@", task.error);
                                                         }
                                                     }

                                                     if (task.result) {
                                                         AWSS3TransferManagerUploadOutput *uploadOutput = task.result;
                                                         // The file uploaded successfully.


                                                         NSLog(@"result = %@",task.result);
                                                     }
                                                     return nil;
                                                 }];

我还在应用程序委托中设置认知 ID。

基于您在错误中看到https://cognito-identity.(null).amazonaws.com/ 的事实，这会让我相信您在创建AWSCognitoCredentialsProvider 时没有正确设置区域。请仔细检查您没有将其设置为AWSRegionUnknown。

2015 年 4 月 17 日更新：Here is the list of Region constants。您应该将其设置为您的身份池所在的区域。目前，Amazon Cognito 仅在 AWSRegionUSEast1 或 AWSRegionEUWest1 中可用。

请注意，您的身份池区域与您可能在应用程序中使用的其他 AWS 服务的区域无关。例如，您可以使用AWSRegionUSEast1 中的身份池来访问AWSRegionSAEast1 中的资源。
