**And this is the ajax call I have made:**

        var data = { 'logindetails': { 'UserName': UN, 'Password': PW } };
        var st = JSON.stringify(data);
        debugger;
        $.ajax({
            type: "POST",
            url: "http://192.168.4.89/mob/AppService.svc/GetUserAuthendication",
            data: st,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (result) {
                ServiceSucceeded(result);
                //// Play with response returned in JSON format
            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert(jqXHR + "-" + textStatus + "-" + errorThrown);
            }


        });

When I host my Wcf service in my local IIS and make an ajax call from my local machine itself, its working fine, but when I host my Wcf service in server and make an ajax call to that Wcf service hosted in server, from my local machine, I couldn't access it.
Please go through this code and help me in finding the problem

推荐答案

.ajax（{
类型： POST，
url：http://192.168.4.89/mob/AppService.svc/GetUserAuthendication，
data：st，
contentType：application / json; charset = utf -8，
dataType：json，
成功：函数（结果）{
ServiceSucceeded（result）;
////使用JSON格式返回的响应播放
}，
错误：函数（jqXHR，textStatus，errorThrown）{
alert（jqXHR + - + textStatus + - + errorThrown）;
}


}）;

当我在我的本地IIS中托管我的Wcf服务并从我的本地机器本身进行ajax调用时，它工作正常，但是当我在服务器中托管我的Wcf服务并对该Wcf进行ajax调用时托管服务器的服务，从我的本地机器，我无法访问它。
请仔细阅读此代码并帮助我找到问题

.ajax({ type: "POST", url: "http://192.168.4.89/mob/AppService.svc/GetUserAuthendication", data: st, contentType: "application/json; charset=utf-8", dataType: "json", success: function (result) { ServiceSucceeded(result); //// Play with response returned in JSON format }, error: function (jqXHR, textStatus, errorThrown) { alert(jqXHR + "-" + textStatus + "-" + errorThrown); } }); When I host my Wcf service in my local IIS and make an ajax call from my local machine itself, its working fine, but when I host my Wcf service in server and make an ajax call to that Wcf service hosted in server, from my local machine, I couldn't access it.
