仅在IE 10中工作的CORS响应，对于chrome和firefox失败 [英] CORS response working in IE 10 only, fails for chrome and firefox

问题描述

Hello,

I am making a cross origin ajax HTTP request from 'http://localhost:8080/[some string value].html' to a remote server machine.Actually this request is made to get a list of HDFS file system information which is installed in the remote server. Request URL is:
 
var formURL =  http://[remote server name]:[port number]/**webhdfs**/v1/xd/?op=LISTSTATUS. 

 and the ajax call is like:
 $.ajax({
		url: formUrl,
		dataType: 'json',
		success: function(response)
 		{
            alert("Response is: "+response);
        }
});

response is expected a json array like below

{"FileStatuses":{"FileStatus":[
{"accessTime":1449652575549,"blockSize":134217728}]}}

While I am getting this response in IE 10, but for all other browsers it's  throwing a browser level error as:

"XMLHttpRequest cannot load http://[remote server name]:[port number]/**webhdfs**/v1/?op=LISTSTATUS. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access."

I searched google, its solution is to write java servlet method to set response header as "Access-Control-Allow-Origin, http://localhost:8080".

As this ajax request is not meant for any server side java method as ajax request generally does, how can I get rid this issue? 

推荐答案

.ajax（{
url：formUrl，
dataType：' json' ，
成功：函数（响应）
{
alert（ 响应是： +响应）;
}
}）;

响应 期望json数组如下

{ FileStatuses：{ FileStatus：[
{ accessTime： 1449652575549 ， blockSize： 134217728 }]}}

当我收到 响应 IE 10 ，但 所有其他浏览器' 抛出浏览器级错误：

XMLHttpRequest无法加载http：// [远程服务器名称]：[端口号] / * * webhdfs ** / v1 /？op = LISTSTATUS。否' Access-Control-Allow-Origin ' 标头出现在请求的资源上。原因' http： // localhost：8080'因此不允许访问。

我搜索了谷歌，其解决方案 将java servlet方法写入 set 响应header as Access-Control-Allow-Origin，http ：// localhost：8080。

As 此 ajax请求是并不意味着 任何服务器端java方法作为 ajax请求通常会做什么，我怎么能 get rid 此问题？
