需求

每天早上核酸检测即将开始，定时发送在线表格二维码到班级微信群
每天下午核酸检测即将结束，定时检测未完成填写的同学名单，发送提醒信息到班级微信群
在线表格设计如下

用了保护所选范围+冻结+条件格式+数据验证构建的简易核酸记录表，要求在校同学每日填报

功能拆分

低功耗小主机，如树莓派，运行微信，开放发信API到公网，demo点此
爬虫采集腾讯文档在线表格内容，demo点此
通过爬虫采集的内容，分析未完成填写的同学名单，通过发信API发送提醒信息到班级微信群
最终效果见下图

左图是早上定时提醒的效果，右图分别是有同学未记录和全部已记录的效果

发信API

#!/usr/bin/python3
import itchat
itchat.auto_login(True, enableCmdQR=2)
 
import bottle
 
def verifyToken(func):
    def wrapper(*args, **kwargs):
        token = bottle.request.json.get('token')
        if token != 'a123456':
            return dict(BaseResponse='invalid token!')
        else:
            return func(*args, **kwargs)
    return wrapper
    
@bottle.route('/api/send_image', method='POST')
@verifyToken
def api_send_image():
    fileDir = bottle.request.json.get('fileDir')
    toUserName = bottle.request.json.get('toUserName')
    return dict(itchat.send_image(fileDir, toUserName))
    
@bottle.route('/api/send', method='POST')
@verifyToken
def api_send():
    msg = bottle.request.json.get('msg')
    toUserName = bottle.request.json.get('toUserName')
    return dict(itchat.send(msg, toUserName))
    
@bottle.route('/api/search_friends', method='POST')
@verifyToken
def api_search_friends():
    remarkName = bottle.request.json.get('remarkName')
    usr = itchat.search_friends(remarkName=remarkName)
    if not usr:
        return dict(BaseResponse='failed')
    usr = usr[0]
    return dict(BaseResponse='succeed', UserName=usr.userName)
    
@bottle.route('/api/search_chatrooms', method='POST')
@verifyToken
def api_search_chatrooms():
    name = bottle.request.json.get('name')
    group =  itchat.search_chatrooms(name=name)
    if not group:
        return dict(BaseResponse='failed')
    group = group[0]
    return dict(BaseResponse='succeed', UserName=group.userName)
 
bottle.run(host='localhost', port=2001, debug=True)

依赖见demo点此
screen /home/pi/itchat_api.py

下面是测试，通过后修改token，通过反代将服务暴露到公网，并加上https

#!/bin/bash
/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"fileDir": "./itchat/COVID.19.testing.png", "toUserName":"filehelper", "token":"a123456"}' \
http://localhost:2001/api/send_image
 
/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"msg": "./itchat/COVID.19.testing.png", "toUserName":"filehelper", "token":"a123456"}' \
http://localhost:2001/api/send
 
/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"remarkName": "没有这个备注", "token":"a123456"}' \
http://localhost:2001/api/search_friends
 
/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"remarkName": "Limour", "token":"a123456"}' \
http://localhost:2001/api/search_friends
 
/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"name": "没有这个群", "token":"a123456"}' \
http://localhost:2001/api/search_chatrooms
 
/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"name": "相亲相爱一家人", "token":"a123456"}' \
http://localhost:2001/api/search_chatrooms

早上提醒

#!/bin/bash
/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"fileDir": "./itchat/COVID.19.testing.png", "toUserName":"filehelper", "token":"a123456"}' \
http://localhost:2001/api/send_image

toUserName从filehelper改为班级群的group.userName
crontab -e
10 7 * * * /home/pi/task/01.sh

获取班级群的group.userName的方法如下

/usr/bin/curl -X POST \
-H "Content-Type: application/json" \
-d '{"name": "临八一班男生群", "token":"a123456"}' \
http://localhost:2001/api/search_chatrooms

下午提醒

通过puppeteer获取腾讯文档在线表格内容

#!/usr/bin/env node
const puppeteer = require('puppeteer-extra')
// add stealth plugin and use defaults (all evasion techniques)
const StealthPlugin = require('puppeteer-extra-plugin-stealth')
puppeteer.use(StealthPlugin())
const fs = require('fs')
 
puppeteer.launch({ headless: true }).then(async browser => {
    const context = browser.defaultBrowserContext();
    context.overridePermissions('https://docs.qq.com', ['clipboard-read'])
    console.log('Running tests..')
    const page = await browser.newPage()
    await page.goto('https://docs.qq.com/sheet/id')
    console.log('Open sheet.html')
    
    await page.waitForSelector('#canvasContainer > div.excel-container > canvas')

    console.log('send Ctrl C')
    
    await page.waitForTimeout(2000)
    
    const table = await page.evaluate(() => navigator.clipboard.readText())
    console.log(table)
    fs.writeFile('test.txt', table, err => {
      if (err) {
        console.error(err)
        return
      }
      //文件写入成功。
    })
    console.log('get clipboard')
    
    await page.screenshot({ path: 'testresult.png', fullPage: true })
    await browser.close()
    console.log(`All done, check the screenshot. ✨`)
    process.exit()
