最近.NET项目上使用JAVA项目中的jsp页面，使用到跨域的信息交互。
jsp端代码，通过监听来自.NET项目所在IP地址，来请求.NET一般处理程序，实现jsp交互信息保存到.NET中：
window.addEventListener('message', function(event){
// 通过origin属性判断消息来源地址
if (event.origin == 'http://192.168.11.195') {
if(event.data=='1'){
var xmlStr = getXmlStr();
var sysId1= '1111222';
var userId1 = '22211112';
var menus1 = xmlStr;
var callback1='?';
var url = 'http://192.168.11.195/BPMS/WebService/MessageExchange.ashx';
$.ajax({
url:url,
data: {sysId:sysId1,userId:userId1,menus:menus1,callback:callback1},
dataType:'jsonp',
type:'post',
processData: true,
success:function(data){
alert(data);
},
error:function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status);
alert(XMLHttpRequest.readyState);
}
});
}
}
}, false);
.NET页面代码，主要是通过向jsp端页面发送带标记请求信息：
