Amazon S3是否允许自定义标头?或者我运气不好?
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();
}

目前,s3支持的standrd http标头数量有限。
目前不支持Access-Control-Allow- *标头:https://forums.aws.amazon.com/thread.jspa?threadID=34281&tstart=0
更新:
添加了对跨源资源共享的支持: https://forums.aws.amazon.com/ann.jspa?annID=1620
S3 Browser Freeware也支持此功能: http://s3browser.com/s3-bucket-cors-configuration.php

今天亚马逊宣布完全支持CORS,因此您现在可以使用HTML5作为Drag& amp;将文件直接删除到Amazon S3。
