Python push applet to subscribe news

This article mainly uses Python to implement a simple call to WeChat applet to subscribe to the message interface.

Call step

1. Get access_token
2. Call the subscription message delivery interface

I won’t talk about getting access_token here. You can get it by calling the interface directly. Here it is mainly for sending subscription messages. Because of the complete and available business code, obtaining access_token also requires some professional processing, such as caching access_token, verifying the validity period of access_token, etc.

Call code

import requests
import json

# json数据格式请求参数
data = {
  "touser": "o9usm0bhIkcbAyxM0RzDXi9tjHhM", # 接收用户的openid
  "template_id": "WZiCliW1zVtHXqX7dGnFNvFO4Bx3MOSjPRA7LAcwQuw", # 模板id
  "page": "pages/index/index",
  "miniprogram_state":"formal",
  "lang":"zh_CN",
  "data": {
      "character_string1": {
          "value": "2021-08-01"
      },
      "thing4": {
          "value": "Python推送小程序订阅消息"
      }
  }
}

# 设置请求头
header = {'Content-Type': 'application/json'}
# 请求地址
url = "https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token=获取到的access_token"
# 请求体
response = requests.post(url, headers=header, data = json.dumps(data))
# 打印请求结果
print(response.text)

Returning the following json means the delivery is successful

{"errcode":0,"errmsg":"ok","msgid":1983688405318189057}

The official document of the WeChat applet is attached here, and the above related parameters can be found in the document to understand its purpose

Combined with GUI

Friends with strong hands-on ability can also combine with Python's own GUI library Tkinter to implement a simple operation interface. Because the access_token is only valid for 2 hours and the number of generations per day is limited, we cannot generate a new access_token every time a message is pushed, otherwise, the number of generations is exhausted and you will not be able to call the interface to send messages.

Therefore, the access_token should be cached locally or in the database, and then each time the subscription message interface is called, the validity period of the access_token is judged. If it has not expired, you can use the locally cached access_token. If it has expired, call the interface to generate a new access_token. , So that the number of access_token calls per day is basically sufficient.
