无法通过iOS 11.4.1将文件上传到S3存储桶（AWS-IOS-SDK-2.6.24）

Question

I'm facing issue while uploading the files on AWS S3 bucket (using AWS-IOS-SDK-2.6.24) from iOS 11.4.1 devices. The same code works fine for iOS 9.xx

Mostly I'm getting timeout error:

    Request headers:
    {
        "Content-Type" = "application/x-amz-json-1.1";
        Host = "cognito-identity.ap-south-1.amazonaws.com";
        "User-Agent" = "aws-sdk-iOS/2.6.24 iOS/11.4 en_US";
        "X-Amz-Date" = 20180718T080347Z;
        "X-Amz-Target" = "AWSCognitoIdentityService.GetCredentialsForIdentity";
    }

I'm following the AWS Documentation, all the required details I gathered from AWS documentations only.

I've configured my info.plist and also added awrconfiguration.json into my project.

I've mentioned the credentials in my AppDelegate Class:

AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc]
                                                          initWithRegionType:AWSRegionAPSouth1
                                                          identityPoolId:@"ap-south-1:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”];


    AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionAPSouth1
                                                                         credentialsProvider:credentialsProvider];
    [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

I'm unable to understand what I'm doing wrong here as the code works fine in older versions of iOS.

My Other question is: If we really need to provide the credentials in the AppDelegate Class, then why do we need to configure info.plist or why need to copy awsconfiguration.json file into our project. What is the way to read the credentials from info.plist or read the awsconfiguration file programmatically, without defining credentials in the AppDelegate.m file ?

Answer 1

This is a partial answer.

Hi,

First, to clear up the confusion. You only need one:

• awsconfiguration.json
• Info.plist
• Code based credentials in AppDelegate (or elsewhere)

Second, to access the configuration from either awsconfiguration.json -or- Info.plist you may construct:

AWSS3TransferUtility *transferUtility = [AWSS3TransferUtility defaultS3TransferUtility];

Can you try only the code based approach and reply here while I debug further?
