C# developed WeChat applet to send template messages

This article mainly introduces the WeChat applet developed in C# to send template messages. Friends who need it can refer to it

Step 1: Get the template ID

There are two methods to obtain the template ID

1. Get the template ID through the template message management interface

2. Manually configure and obtain the template ID on the WeChat public platform

Step 2: In the e8b36d49ce73ede15e584e9dd86e79e9 component of the page, when the attribute report-submit is true, it can be declared to need to send a template message. At this time, click the button to submit the form. Get formId, used to send template messages. Or when the user completes the payment behavior, the prepay_id can be obtained and used to send the template message.

Step 3: Call the interface to deliver the template message

The important thing today is to talk about how to implement the third step. The previous steps are relatively simple and can be skipped.

-------------------------------------------------- -------------------------------------------------- ------

1. Get access_token

https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid= APPID&secret=APPSECRET

The access_token

will be used later when sending the template message

2. Send the template message

Interface address: (ACCESS_TOKEN required Replace with the access_token obtained above)

https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token=ACCESS_TOKEN

Note the instructions : Since WeChat currently does not allow developers to directly use the https://api.weixin.qq.com interface to obtain data on the front end, the following operations must be completed by the server background.

Official POST parameters:

{
 "touser": "OPENID", 
 "template_id": "TEMPLATE_ID", 
 "page": "index",   
 "form_id": "FORMID",   
 "data": {
  "keyword1": {

}
   var l = "https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token=" + access_token;
   var tempData = new
   {
    touser = openid,
    template_id = "VErasH9Plzmyw9-PQjiggkBCa3hOU30qfvTaxD******",//这个是1、申请的模板消息id，
    page ="pages/index/index",
    form_id = formId,
    data = new
    {
     keyword1 = new
     {
      value = title,
      color = "#666666"
     },
     keyword2 = new
     {
      value = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"),
      color = "#9b9b9b"
     },
     keyword3 = new
     {
      value = Remarks,
      color = "#9b9b9b"
     }
    },
    color = "#666666"
   };
   X.Component.Tools.WebClient wc = new X.Component.Tools.WebClient();
   var result = tempData.ToJson(); //Newtonsoft.Json.JsonConvert.SerializeObject(tempData);
   wc.Encoding = System.Text.Encoding.UTF8;
   var obj = wc.Post(l, result); //得到返回的结果

Pay attention to the page path
