我存储在Amazon S3中JSON对象，我想在Javascript中直接加载数据S3。我的GET看起来pretty的通用的：

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);
    }
});

我收到以下错误：

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.

我可以使用curl，或者从我的浏览器导航到那里直接得到S3的URL。难道我真的要通过自己的服务器上有代理所有这些要求？

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?

推荐答案

S3现在支持使用CORS文件跨域请求

S3 now supports Cross Domain Requests using CORS file
