Template message reply for WeChat development

WeChat development is becoming more and more popular in programming. We have shared a lot about the functions of WeChat mini programs. In this article, we will continue to introduce how to implement the template message reply function in WeChat development.

On the WeChat public platform, there is a template message reply interface: it can be used to reply to specific messages - for example, after the user places an order, reply to the user that your order is being processed... For example, the picture below:

#After the user performs some operations, the service account can return a specific message—this is the template message.

To implement replying to template messages, your public account must be certified by WeChat. If it is a personal subscription account, WeChat certification is not supported for the time being. However, it does not affect the testing ----- You can use the test public account:

When using the test account, the configuration of the interface information will not be discussed, you can refer to My previous blog.

After using the QR code to log in to the test account, you need to use your WeChat ID to follow the test account, otherwise you will not see the reply to the template message.

When I was doing testing, I used a plug-in for the Chrome browser: postman. This plug-in can specify to send various HTTP requests such as GET and POST. It is powerful and useful when testing interfaces.

1. Send a GET request to obtain the access_token of the test number: https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=your test number appID&secret=your test number appsecret

2. Set the industry:

Send a POST request with parameters:

Request: https://api.weixin.qq.com/cgi- bin/template/api_set_industry?access_token=The access_token you just got

Parameters:

{
    "industry_id1":"1",
    "industry_id2":"2"
   }

The 1 and 2 in the parameters represent For specific industries, please refer to the document: http://mp.weixin.qq.com/wiki/12/bd383158b0f8435c07b8b6bc7cdbac9c.html

Please send a specific post request to everyone You can use curl to send it, it shouldn't be difficult. I use postman to send. After the sending is completed, a successful json message is returned, and then you can proceed to the next step

3. Obtain the template ID: You can customize this, or you can use some built-in WeChat.

For example, use a custom template ID: There is a "New Test Template" in your test account

Submit After that, you can see that your template ID appears:

Then another way to generate the template ID is to send a post request (you can send it with curl or use postman)

Request: https://api.weixin.qq.com/cgi-bin/template/api_add_template?access_token=ACCESS_TOKEN

Parameters:

{
     "template_id_short":"TM00015"
   }

TM00015 is the ID of the template built into WeChat. You can find it in the graphical interface at https://mp.weixin.qq.com (WeChat authentication required)

4. After obtaining the template ID, refresh your test account page and you will see the following:

5. Use the template_id_short you obtained and send another post request. You can get a msgid:

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

The data sent :

{
     "touser":"测试号的关注者的openId",
     "template_id":"你刚才得到的模板ID",
     "url":"关注者点击你的模板消息时跳转的链接",      
     "data":{
         "first": {
           "value":"恭喜你购买成功！",
           "color":"#173177"
         },
         "orderMoneySum":{
           "value":"666",
           "color":"#173177"
         },
         "orderProductName": {
           "value":"男士正装",
           "color":"#173177"
         },
         "Remark":{
           "value":"欢迎再次购买！",
           "color":"#173177"
         }
     }
   }

color indicates the color of the fields in your template

The official document does not explain the above parameters. I wrote each of them in Chinese above. The meaning of each field, it should be noted that touser is not the "WeChat ID" of the follower on the WeChat client, but the WeChat ID as shown below

Use the parameter After sending in post mode, you will get a msgid:

#When you get this successful response, at the same time, your test public account should also return a template message to you ( Followers)
