跨域ajax请求基本身份验证

Question

我正在制作跨域ajax请求来获取一些数据.REST服务具有Basic authentication(设置IIS).

$.ajax({
            type: "GET",
            xhrFields: {
                withCredentials: true
            },
            dataType: "jsonp",
            contentType: "application/javascript",
            data: myData,
            async: false,
            crossDomain: true,
            url: "http://xx.xx.xx.xx/MyService/MyService.svc/GetData",
            success: function (jsonData) {
                console.log(jsonData);
            },
            error: function (request, textStatus, errorThrown) {
                console.log(request.responseText);
                console.log(textStatus);
                console.log(errorThrown);
            }
        });

当我发出此请求时,它会提示我输入凭据,我必须手动输入凭据才能获得响应.我们可以通过请求本身发送这些凭据吗？

});
