How do you generate an AWS Signature in ReadyAPI/SoapUI

Question

I am trying to perform a GET of an object on S3 storage using ReadyAPI (or SoapUI).

Here is the documentation for how it is done

In order to make the request I require a "signature" to be generated. How can this be done within the ReadyAPI suite itself?

p.s. The AWS API plugin doesn't currently function for my region (eu-west-1)

This is really easy if the use of the AWS JDK is an option for you. I tried many hours to generate my own signature for REST API access to AWS. After I discovered the AWS JDK it was a matter of minutes. All can be done with a few lines of groovy script code within ReadyAPI/SoapUI NG.

• Download, install, configure AWS CLI. (why this? If you configure your secret key in the CLI, the JDK will recognize the configuration and configuration location on your computer and use it)

• Be on latest version of ReadyAPI/SoapUI

• Download AWS JDK and unzip

• Copy aws-java-sdk-x.xx.xx.jar to your ReadyAPI/SoapUI installation Lib folder and restart ReadyAPI/SoapUI

• Groovy script step code utilizing AWS JDK to list buckets that you have access to(commented out stuff would let you create buckets):

  import com.amazonaws.AmazonClientException;
  import com.amazonaws.AmazonServiceException;
  import com.amazonaws.auth.profile.ProfileCredentialsProvider;
  import com.amazonaws.regions.Region;
  import com.amazonaws.regions.Regions;
  import com.amazonaws.services.s3.AmazonS3;
  import com.amazonaws.services.s3.AmazonS3Client;
  import com.amazonaws.services.s3.model.CreateBucketRequest;
  import com.amazonaws.services.s3.model.ListBucketsRequest;
  import com.amazonaws.services.s3.model.GetBucketLocationRequest;
  
  
  def AmazonS3 s3client = new AmazonS3Client(new ProfileCredentialsProvider());
  //s3client.setRegion(Region.getRegion(Regions.US_WEST_2));
  
  try {
  //   def String bucketName     = "soapui-bucket";
  //   if(!(s3client.doesBucketExist(bucketName))) {
  //      // Note that CreateBucketRequest does not specify region. So bucket is created in the region specified in the client.
  //      s3client.createBucket(new CreateBucketRequest(bucketName));
  //   };
  
     // Get location.
  //   String bucketLocation = s3client.getBucketLocation(new GetBucketLocationRequest(bucketName));
  //   log.info("bucket location = " + bucketLocation);
  
     // A couple of ways to list buckets.
     bucketList = s3client.listBuckets();
     log.info("bucketList All= " + bucketList);
  //   bucketList = s3client.listBuckets(new ListBucketsRequest());
  //   log.info("bucketList Owner= " + bucketList);
  
  }
  catch (AmazonServiceException ase) {
              log.info("Caught an AmazonServiceException, which " +
                      "means your request made it " +

              log.info("AWS Error Code:   " + ase.getErrorCode());

                      "communicate with S3, " +
                      "such as not being able to access the network.");
