微信推送模板消息

在微信的服务号中，往往需要对订阅用户推送消息，有时候会用到模板消息，下面的代码仅供参考，个人测试成功。

@access_token 请调用 https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=@appid&secret=@secret 接口获取。

        public static void Send()
        {
            dynamic postData = new ExpandoObject();
            postData.touser = "OpenId";
            postData.template_id = "template_id";
            postData.url = string.Empty;
            postData.topcolor = "#FF0000";
            postData.data = new ExpandoObject();
            var data = new[]
            {
                new Tuple<string, string, string>("title", "航班延误通知", "#FF0000"),
                new Tuple<string, string, string>("trainNumber", "10分钟", "#FF0000"),
                new Tuple<string, string, string>("fromto", "上海-北京", "#FF0000"),
                new Tuple<string, string, string>("formerTime", "2015/7/31 14:36:32", "#FF0000"),
                new Tuple<string, string, string>("Time", "2015/07/31 14:36:32", "#FF0000"),
                new Tuple<string, string, string>("number", "10分钟", "#FF0000"),
                new Tuple<string, string, string>("reason", "天气原因", "#FF0000"),
                new Tuple<string, string, string>("remark", "请关注我们的微信通知", "#FF0000")
            };
            var dataDict = (IDictionary<string, object>)postData.data;
            foreach (var item in data)
            {
                dataDict.Add(item.Item1, new { value = item.Item2, color = item.Item3 });
            }
            string json = ((object)postData).Serialize();

            Console.WriteLine(json);
            var r = NetUtils.CreateHttpResponse(@"https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=@access_token", json);
            Console.WriteLine(r);
        }
