1.5大功告成

2.开始写代码

2.1 新建一个文件 test.js

// 发送消息到钉钉
function sendDingDing(content) {const request = require('request');const crypto = require('crypto');var dingdingUrl = 'https://oapi.dingtalk.com/robot/send?access_token=8659dec91bbf5f4405456926c24c6712c2c5ab98814c37af52f7bf503de9a598';var secret = 'SEC2c689174c4a8ed49c8a7309a490cd98e0e7f7bc788bb7232d53c738eb5f5d008';var timestamp = new Date().getTime();var stringToSign = timestamp + '\n' + secret;var base = crypto.createHmac('sha256',secret).update(stringToSign).digest('base64');var sing = encodeURIComponent(base);var dingdingStr = dingdingUrl + `&timestamp=${timestamp}&sign=${sing}`;var data = {json: {"msgtype": "text","text": {"content":content}},encoding: 'utf-8',headers: {'Content-Type': 'application/json'}}request.post(dingdingStr, data, function(error,res,body) {if(!error && res.statusCode == 200) {console.log('body is ',body);}})
}sendDingDing("在奋进中拥抱梦想 成就未来")

备注1：替换 dingdingUrl  替换 secret
