以前是阿里云存储的，现在需要改成亚马逊的存储既aws s3.改动的地方。
var multipartParams = {
        'key' : fn==''?'':$(fn).attr("fn"),
        //'policy' : policyBase64,
        //'OSSAccessKeyId' : accessid,
        'AWSAccessKeyId':accessid,
        'success_action_status' : '201', // 让服务端返回200,不然，默认会返回204
        'signature' : signature,
        'acl' : 'public-read'
    }

把OSSAccessKeyId改成AWSAccessKeyId，然后密钥和url换成亚马逊的。然后把policy去掉
s3里的文件夹的读写权限都要开放
