 控制器下的代码

       [HttpPost]
        public ActionResult Index6()
        {
            string zh ="XXXXXXX";//短信接口账户
            string mm = "123456";//账户密码

            string uid = Request["uid"];//用户ID
            string code = Request["code"];//随机数
//内容 string nr = "您好用户:" + uid + ",你的验证码为:" + code + "请尽快输入!";
//短信接口通道地址如:
string url = "http://www.6610086.net/jk.aspx?zh=" + zh + "8&mm=" + mm + "&hm=" + dealType + "&nr=" + nr + "&sms_type=" + sms_type; Response.Redirect(url); // Response.Write("<script>$.ajax({type: ‘POST‘, dataType: ‘text‘, url: " + url + ",data:null,error: function (XMLHttpRequest, textStatus, errorThrown) { },success: function (msg) { }});</script>"); //Response.Write("<script>$.ajax([type:‘POST‘,dataType:‘text‘,]);</script>"); return View(); }
