let requestTimer = null;

let req = http.get("http://www.baidu.com", (res) =>{

    if(res.statusCode === 200){

        clearTimeout(requestTimer);//请求超时之前完成，清除超时定时器

    }

});

requestTimer  = setTimeout(() => {

     req.emit("timeout", {"msg": "请求超时了"});//如果请求超时了则发送timeout事件

}, 1000);

req.on("timeout",(msg) => {//监听timeout事件并终止请求

    console.log(`收到timeout事件!`);

    req.abort();

    console.log(`终止请求`);

    let resStr = "";
