如何使用WCF服务连接Microsoft Dynamic CRM帐户？

Question

我想使用服务器上托管的WCF服务连接Microsoft Dynamic CRM帐户。目前，如果我在IIS服务器中托管服务，我可以连接到它，但是当我将服务托管到服务器时，我无法连接。

以下是我为理解而创建的示例：

<input id="Button1" type="button" value="Get Data from Crm Call" onclick="checkConnection()" />

function checkConnection() {
    var requestData = {
        //data of CRM like user name password etc
    };

    //Service call
    try {
        $.ajax({
            type: "POST",
            // url: "http://localhost:13213/Service1.svc/savedata", //this is working fine
            url: "http://mdcportal.biztechconsultancy.com/Service1.svc/savedata/",
            data: JSON.stringify(requestData),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data, status, XMLHttpRequest) {
                debugger;
                //I get success for service call
                alert(data.ResponseData);
            },
            error: function (xhr) {
                alert("error"+xhr.responseText);
            }
        });
    } catch (err) {
        alert(err.message + " Error");
    }
}

WCF服务

//service call
public class Service1 : IService1
{
    public RequestData authentication(CRMCredential objauthentication)
    {
        //get data successfully from objauthentication
        RequestData result = new RequestData();
        try
        {
            List<PostData> itemlist = new List<PostData>();
            ClientCredentials clientCredentials = new ClientCredentials();
            clientCredentials.UserName.UserName = objauthentication.Username;  //Username;
            clientCredentials.UserName.Password = objauthentication.Password;
            Uri oUri = new Uri(objauthentication.Uri);

            //go to catch from following fine
            _serviceProxy = new OrganizationServiceProxy(oUri, null, clientCredentials, null);

            //few code here to populate other information

        }
        catch (Exception ex)
        {
            result.isSuccess = false;
            CallDetails objcalldetail = new CallDetails();
            objcalldetail.code = ex.ToString();
            objcalldetail.message = "CRM authentication failed";
            result.CallDetail = objcalldetail;
        }
        return result;
    }
}

错误：

请注意，如果我可以通过在IIS中托管wcf服务来尝试连接，它工作正常。

如果我错过了什么，请建议我。
