我在AWS Elastic Transcoder上创建了一个管道,我正在尝试使用它的api为它创建作业.这就是我正在做的事情.

Parse.Cloud.define("createJobOnElastic", function(request, response){

  Parse.Cloud.httpRequest({
 
    method: 'POST',
    headers: {
     'Content-Type': 'application/json; charset=UTF-8',
     'Accept': '*/*',
     'Host': 'elastictranscoder.us-east-1.amazonaws.com:443',
     'Content-Length': '300',
     "x-amz-date": new Date().getTime()
    },

    url: 'https://aws.elastictranscoder.us-east-1.amazonaws.com:443/2012-09-25/jobs',
    body:{
        
        "Input":{
            "Key":"fullViewLq1teqJ1Ym-nHGwcJtRuL-1433857991.895335.mp4",
            "FrameRate":"auto",
            "Resolution":"auto",
            "AspectRatio":"auto",
            "Interlaced":"auto",
            "Container":"mp4"
          },
  "OutputKeyPrefix":"compressed/",
   "Outputs":[
      {
         "Key":"fullViewLq1teqJ1Ym-nHGwcJtRuL-1433857991.895335.mp4",
         "Rotate":"0",
         "PresetId":"1351620000001-000030"
      }
   ],
   "PipelineId":"xxxxxxxxx-xxxx"
 },
    success: function(httpResponse) {
            // console.log(httpResponse);

            alert("Worked TRANCODER");
            response.success();
            },
        error: function(httpResponse) {
            // console.error(httpResponse);
            alert("Did not work TRANSCODER");
            response.error(httpResponse);
        }
 
    });


});

我可以看到我的网址可能不对,但那是因为我无法确定我应该从他们的文档中发送请求的网址:http://docs.aws.amazon.com/elastictranscoder/latest/developerguide /create-job.html#create-job-description

这是我作为回应得到的:

我一直坚持尝试将iOS与iOS一起使用2天.我从这里下载了示例项目:https://github.com/awslabs/aws-sdk-ios-samples

我完全按照步骤说,我用cocoapods链接所有库.

我还创建了一个存储桶,然后再按照如何获取ID的步骤在代码中进行更改,如下所示:

AWSCognitoCredentialsProvider *credentialsProvider = [AWSCognitoCredentialsProvider
                                                      credentialsWithRegionType:AWSRegionUSEast1
                                                      accountId:AWSAccountID
                                                      identityPoolId:CognitoPoolID
                                                      unauthRoleArn:CognitoRoleUnauth
                                                      authRoleArn:nil];

所以基本上当我试图上传一些图像/文件时(在亚马逊使用S3存储服务的例子中,我收到一个错误:

2014-09-04 15:11:57.475 S3TransferManagerSample[5437:400b] AWSiOSSDKv2 [Error] AWSCredentialsProvider.m
  line:356 | __40-[AWSCognitoCredentialsProvider refresh]_block_invoke299 | Unable to refresh. 
  Error is [Error Domain=com.amazonaws.AWSSTSErrorDomain Code=0 "The operation couldn’t be completed. (com.amazonaws.AWSSTSErrorDomain error 0.)" 
   UserInfo=0x14d17770 {Type=Sender, Message=Not authorized to perform sts:AssumeRoleWithWebIdentity, __text=(
"\n    ",
"\n    ",
"\n    ",
"\n  "
), Code=AccessDenied}]

为了清楚起见,我已经创建了一个角色并为其提供了一个策略:AdministratorAccess并使用角色ARN来设置

unauthRoleArn:CognitoRoleUnauth   

我已阅读文档,似乎无法在任何地方找到问题.我觉得它与角色和赋予角色的政策有关.

我非常感谢有关如何入门或如何解决此问题的任何提示.

谢谢,如果你需要关于这个问题的更多细节,请随意评论,我会给予更多,因为这个问题有点冗长.

我有一个图像,我以这种方式在AWS上传到我的存储桶:

BFTask *task = [BFTask taskWithResult:nil];

        [[task continueWithBlock:^id(BFTask *task) {

            self.URL = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:@"test"]];

            NSData *data = UIImagePNGRepresentation(image);
            //NSMutableString *dataString = [NSMutableString new];
            [data writeToURL:self.URL atomically:YES];
            return nil;

        }]continueWithExecutor:[BFExecutor mainThreadExecutor] withBlock:^id(BFTask *task) {

            self.uploadRequest1 = [AWSS3TransferManagerUploadRequest new];
            self.uploadRequest1.bucket = S3BucketName;
            self.uploadRequest1.key = S3KeyUploadName1;


            self.uploadRequest1.body = self.URL;
            return nil;
        }];

            AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];

            [[transferManager upload:self.uploadRequest1] continueWithExecutor:[BFExecutor mainThreadExecutor] withBlock:^id(BFTask *task) {
                if (task.error != nil) {
                    if( task.error.code != AWSS3TransferManagerErrorCancelled
                       &&
                       task.error.code != AWSS3TransferManagerErrorPaused
                       )
                    {
                        NSLog(@"Upload Failed!");
                    } …
