微信公众平台开发 --发送模版消息

发送模版消息是微信服务号给某个用户发送模版消息，类似于APP的推送通知；

1、添加模版消息

 　 在页面的左上 有一个添加功能插件的 按钮，如题

　　　　

       添加完成后，我们就可以在左边的菜单栏看到 相应的信息了；

2、添加模版消息

　　　　

   详情里面有关模版的介绍，和发送短信需要传送的数据；

3、发送模版消息

　　

　　

接口调用请求说明
http请求方式: POST
https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=ACCESS_TOKEN

会根据ACCESS_TOKEN来请求数据
请求数据格式：
　　

 {
           "touser":"OPENID",
           "template_id":"ngqIpbwh8bUfcSsECmogfXcV14J0tQlEpBO27izEYtY",
           "url":"http://weixin.qq.com/download",            
           "data":{
                   "first": {
                       "value":"恭喜你购买成功！",
                       "color":"#173177"
                   },
                   "keynote1":{
                       "value":"巧克力",
                       "color":"#173177"
                   },
                   "keynote2": {
                       "value":"39.8元",
                       "color":"#173177"
                   },
                   "keynote3": {
                       "value":"2014年9月22日",
                       "color":"#173177"
                   },
                   "remark":{
                       "value":"欢迎再次购买！",
                       "color":"#173177"
                   }
           }
       }

在调用模板消息接口后，会返回JSON数据包。正常时的返回JSON数据包示例：

    {
           "errcode":0,
           "errmsg":"ok",
           "msgid":200228332
    }

                return string.Empty;
            }
        }

OK 消息可以发送了；
