webservice使用windows身份验证,ajax请求报错401未授权的解决办法

$.ajax({
    type: "GET",
    url: service_url,
    dataType: "xml",
    data: "ParamId=" + FormId.value,
    processData: false,
    xhrFields: {
        withCredentials: true
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) { ajaxError(XMLHttpRequest, textStatus, errorThrown); },
    success: function(xml) { DoSomething(xml); }
});

方法:加上红色标注部分

winform调用:
var service=new xxxxService();
service.Credentials = System.NET.CredentialCache.DefaultCredentials;
