nodejs通过钉钉群机器人推送消息的实现代码

import * as request from "request";
import * as log4js from "log4js";
const logger = log4js.getLogger("DingdingBot");
const ApplicationTypeHeader:string = "application/json;charset=utf-8";
// DingdingBot
// https://open-doc.dingtalk.com/microapp/serverapi2/qf2nxq
export class DingdingBot{
  private readonly _webhookUrl:string;
  constructor(webhookUrl:string){
    this._webhookUrl = webhookUrl;
  }
  public pushMsg (msg: string, atMobiles?: Array<string>): boolean{
    try {
      let options: request.CoreOptions = {
        headers: {
         "Content-Type": ApplicationTypeHeader
        },
        json: {
          "msgtype": "text", 
          "text": {
            "content": msg
          }, 
          "at": {
            "atMobiles": atMobiles == null ? [] : atMobiles,
            "isAtAll": false
          }
        }
       };
      request.post(this._webhookUrl, options, function(error, response, body){
        logger.debug(`push msg ${msg}, response: ${JSON.stringify(body)}`);
      });
    }
    catch(err) {
      console.error(err);
      return false;
    }    
  }
}

// botWebhookUrl 为对应钉钉机器人的 webhook 地址
let bot = new DingdingBot(botWebhookUrl);;
// 直接推送消息
bot.pushMsg("测试消息");
// 推送消息并 @ 某些人
var mobiles = new Array<string>();
mobiles.push("13255573334");
bot.pushMsg("测试消息并@", mobiles);
