Amazon S3 和跨源资源共享 (CORS)
Amazon S3 是否允许自定义标头？还是我运气不好？
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST, GET, OPTIONS
Access-Control-Allow-Headers: X-SOMETHING
Access-Control-Max-Age: 1728000
示例
var request = new XMLHttpRequest();
var url = 'http://example.s3.amazonaws.com/templates/welcome.html';
function callOtherDomain(){
request.open('GET', url, true);
request.withCredentials = "true";
request.onreadystatechange = handler;
request.send();
}
Does Amazon S3 allow custom headers? Or am I out of luck?
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST, GET, OPTIONS

var url = 'http://example.s3.amazonaws.com/templates/welcome.html';
function callOtherDomain(){
request.open('GET', url, true);
request.withCredentials = "true";
request.onreadystatechange = handler;
request.send();
}

今天，Amazon 宣布完全支持 CORS，因此您现在可以使用 HTML5 进行拖放等操作。将文件直接拖放到 Amazon S3。
Today Amazon announces the complete support for CORS, so you can now use HTML5 for example for Drag & Drop files directly to Amazon S3.
