How to send notifications to WeChat with Python?

1. What are the notification methods?

Common notification methods are: email, phone, SMS, WeChat. SMS and phone calls: usually chargeable and rarely used; email: suitable for notification with file type, more formal, and used for archiving; WeChat: suitable for alarm type notification, more convenient. The WeChat mentioned here is enterprise WeChat.

The purpose of this article is to send messages to corporate members through the corporate WeChat application.

2. How to realize enterprise WeChat notification?

1. Create a new application

Log in to the web version of Enterprise WeChat (https://work.weixin.qq.com), click Application Management → Application → Create Application

Upload the logo of the application, enter the application name (new bond), and then select the visible range to successfully create an alarm application

2. Get Secret

Using Python to send alert requests, in fact, only two interfaces are used:

Get Token  : https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={corpid}&corpsecret={secret}

Send request: https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={token}

As you can see, the most important are the corpid and secret:

Corpid: Uniquely identifies your business

secret: the application-level key, with which the program knows which application of the enterprise you want to send

Corpid can be obtained through my enterprise → enterprise information → enterprise id

The secret can be obtained by clicking on the newly created application (new bond) → view secret → send

Finally fill in the following constants with corpid and secret.

3. Code implementation

import json
import time
import requests
'''

'''

CORP_ID = "xxxx"
SECRET = "xxxx"

class WeChatPub:
    s = requests.session()

    def __init__(self):
        self.token = self.get_token()

    def get_token(self):
        url = f"https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={CORP_ID}&corpsecret={SECRET}"
        rep = self.s.get(url)
        if rep.status_code != 200:
            print("request failed.")
            return
        return json.loads(rep.content)['access_token']

    def send_msg(self, content):
        url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=" + self.token
        header = {
            "Content-Type": "application/json"
        }
        form_data = {
            "touser": "FengXianMei",#接收人
            "toparty": "1",#接收部门
            "totag": " TagID1 | TagID2 ",#通讯录标签id
            "msgtype": "textcard",
            "agentid": 1000002,#应用ID
            "textcard": {
                "title": "债券打新提醒",
                "description": content,
                "url": "URL",
                "btntxt": "更多"
            },
            "safe": 0
        }
        rep = self.s.post(url, data=json.dumps(form_data).encode('utf-8'), headers=header)
        if rep.status_code != 200:
            print("request failed.")
            return
        return json.loads(rep.content)

if __name__ == "__main__":
    wechat = WeChatPub()
    timenow = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
    wechat.send_msg(f"<div class=\"gray\">{timenow}</div> <div class=\"normal\">注意！</div><div class=\"highlight\">今日有新债，坚持打新！</div>")
    print('消息已发送！')
