I am new to node and want to write a crawler to crawl Sina Weibo comments, but I found that the page is dynamically generated by JS and cannot be crawled with the http module, so I used phantomjs to crawl it (I heard it will be slower, It has been running for nearly 15 minutes. It is too slow. I wonder if I wrote it wrong), but it still doesn’t work. Is there any way to crawl web pages similar to Sina Weibo?

let page=require("webpage").create();
let url="http://weibo.com/1713926427/Etq2WnSiR?filter=hot&root_comment_id=0&type=comment";
/*page.settings = {
    javascriptEnabled: true,
    loadImages: false,
    webSecurityEnabled: false,
    userAgent: 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.137 Safari/537.36 LBBROWSER'
};*/
page.open(url,(status)=>{
    console.log("Status:"+status);
    if(status=="success"){
        let val = page.evaluate(()=>{
            var list_box=document.querySelector(".list_box");
            console.log(list_box);
            return list_box
        });
        console.log(val)
    }else{
        console.log("failed")
    }
    phantom.exit();
});
