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());
    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 " +
                        "to Amazon S3, but was rejected with an error response" +
                        " for some reason.");
                log.info("Error Message:    " + ase.getMessage());
                log.info("HTTP Status Code: " + ase.getStatusCode());
                log.info("AWS Error Code:   " + ase.getErrorCode());
                log.info("Error Type:       " + ase.getErrorType());
                log.info("Request ID:       " + ase.getRequestId());
    catch (AmazonClientException ace) {
                log.info("Caught an AmazonClientException, which " +
                        "means the client encountered " +
                        "an internal error while trying to " +
                        "communicate with S3, " +
                        "such as not being able to access the network.");
                log.info("Error Message: " + ace.getMessage());
    log.info 'Test Step "' + testRunner.runContext.currentStep.name + '" done...';
