Question

I have recently been trying ot write code to add and delete content form an Amazon S3 bucket. I am completely new to Amazon S3 and the AmazonWS .Net SDK.

The bucket region endpoint is http://sqs.eu-west-1.amazonaws.com so I constructed my client like this:

_s3Client = AWSClientFactory.CreateAmazonS3Client(accessKey, awsSecretKey, new AmazonS3Config().WithServiceURL("http://sqs.eu-west-1.amazonaws.com"));

If I leave out the AmazonS3Config bit I get this error:

A redirect was returned without a new location. This can be caused by
attempting to access buckets with periods in the name in a different
region then the client is configured for.

When I put in the AmazonS3Config bit I no longer get that error but I appear to have no access to this bucket at all or any other bucket that I would usually have access to. Any request I send returns null.

I have tested my code with other buckets that are configured to the standard US region and it all works well. The single difference is in the CreateAmazonS3Client method where I set the config with the EU endpoint.

Could anybody give me some guidance on how I should set up my client to work with a bucket in the EU(Ireland) region. I have been searching for a few hours and every tutorial or document I have followed has not worked so far.

Just use the standard endpoint – s3.amazonaws.com

AmazonS3Config S3Config = new AmazonS3Config {
    ServiceURL = "s3.amazonaws.com",
    CommunicationProtocol = Amazon.S3.Model.Protocol.HTTP
};

AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(AWS_Key, AWS_SecretKey, S3Config);

PutObjectRequest UploadToS3Request = new PutObjectRequest();
UploadToS3Request.WithFilePath(localPath)
                 .WithBucketName(bucket)
                 .WithKey(key);

client.PutObject(UploadToS3Request);
