方法一：jsonp

后台：

 [AllowAnonymous]
        public string getSjyZhzs()
        {
            string jsonpCallback = Request.QueryString["jsonpCallback"];
            var AllCompositeIndex = new
            {
                PassRate = 91,
                VideoLinkNum = 0,
                IncidenceRate = 99,
                DurationConflictMediation = 3.4,
                AppointmentTime = 2.3,
                CompositeIndex = 95,
                Duration = 34,
                MajorEvents = 1,
                AllocationRate = 98
            };
            return jsonpCallback + "({"data":" + new JavaScriptSerializer().Serialize(AllCompositeIndex) + "})";
