The request signature we calculated does not match the signature you provided.

Hi,

I am using latest aws-java-sdk-s3', version: '1.11.158'. I am getting SignatureDoesNotMatch error. I am using below code.

The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method. com.amazonaws.services.s3.model.AmazonS3Exception: The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method. (Service: Amazon S3; Status Code: 403; Error Code: SignatureDoesNotMatch; Request ID: null

    ClientConfiguration clientConfiguration = new ClientConfiguration();
    AWSCredentials awsCredentials = new BasicAWSCredentials("XXX","XXX");
    AmazonS3 amazonS3Client = AmazonS3ClientBuilder.standard().withCredentials(new  AWSStaticCredentialsProvider(awsCredentials)).withClientConfiguration(clientConfiguration)
            .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("https://storage.googleapis.com","Multi-Regional")).build();

    String keyName = UUID.randomUUID().toString();
    FileInputStream f = new FileInputStream(new File(filePath));
    TransferManager tx =  TransferManagerBuilder.standard().withS3Client(amazonS3Client).build();

    // Request server-side encryption.
    ObjectMetadata objectMetadata = new ObjectMetadata();
    objectMetadata.setSSEAlgorithm(ObjectMetadata.AES_256_SERVER_SIDE_ENCRYPTION);
    objectMetadata.setContentType("application/octet-stream");

    tx.upload("XX", keyName, f,objectMetadata);

Hi @kirankumar-mahi!

Thanks for filing an issue! I'm trying to understand the context for your issue. What is your end goal for using aws-java-sdk-s3 with Google Cloud Storage?

[frankyn]

I missed the last line in your script. IIUC, you're uploading a file to Google Cloud Storage using the aws-java-sdk-s3 client library and you're seeing the SignatureDoesNotMatch error?

@kirankumar-mahi, I was able to get passed this issue by using a different version of the signature (reference). I added the solution below, please let me know if you have any trouble. I tested this with version 1.11.158 and 1.11.160 for aws-java-sdk-s3.

  ClientConfiguration clientConfiguration = new ClientConfiguration();
  // Solution is update the Signer Version. 
  clientConfiguration.setSignerOverride("S3SignerType"); 

  AWSCredentials awsCredentials = new BasicAWSCredentials("XXX","XXX");
  AmazonS3 amazonS3Client = AmazonS3ClientBuilder.standard()
    .withCredentials(new  AWSStaticCredentialsProvider(awsCredentials))
    .withClientConfiguration(clientConfiguration)
    .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("https://storage.googleapis.com","Multi-Regional")).build();

  String bucketName = "bucket_name";
  String keyName = UUID.randomUUID().toString();
  String filePath = "path/to/file.ext";

  // I uploaded the file differently as `TransferManager` would hang after it completed
  amazonS3Client.putObject(new PutObjectRequest(bucketName, keyName, new File(filePath)));

It got resolved. Thanks. Closing this

@frankyn @kirankumar-mahi I have some issues with listObjects. Created new issue here

@frankyn I found this same error in the version 1.11.602 of SDK.

Could you provide more context on the issue you're experiencing @allpereira?
