Allow AJAX GETs from Amazon S3? (Access-Control-Allow-Origin)

I'm storing JSON objects in Amazon S3, and I'd like to load that data directly from S3 from Javascript. My GET looks pretty generic:

$.ajax({
    'type':'GET',
    'url':'http://s3.amazonaws.com/mybucketname/'+id,
    'dataType':'text',
    'success':function(msg) {
        alert(msg);
    }
});

I get the following error:

XMLHttpRequest cannot load http://s3.amazonaws.com/whatever/whatever. Origin http://mylocalhostname:9000 is not allowed by Access-Control-Allow-Origin.

I can get that URL from S3 using curl, or by navigating there directly from my browser. Am I really going to have to proxy all of these requests through my own servers?

Solution

  • S3 now supports Cross Domain Requests using CORS file.
