这个确实有点变态,不过可以模拟手机去访问(改user agent).能得到评论数据,是静态的html.

仔细看请求,里面有个就是在算参数,压缩过的js,看的头疼.

不用管他怎么生成的，暴力一点，headers全部带上，参数全部一致，肯定OK

看起来可能是base64编码或者是加密过。跟其他参数相关，怀疑是个签名参数防抓取用的。

是下面这个代码生成的，看不懂：
,_getElevenValue:function(e){

function o(e){
    for(var o=["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"],n="",t=0;e>t;t++){
        var i=Math.ceil(25*Math.random());
        n+=o[i]
    }
    return n
}
    
var n,t=o(7),i=!1;
if(!hotelDomesticConfig.cas.OceanBall)return e.resolve("");
for(;window[t];)
  t=o(15);
n=hotelDomesticConfig.cas.OceanBallUrl+"?callback="+t+"&_="+(new Date).getTime()
 ,window[t]=function(o){
                   window[t]=void 0;
                   var n="";
                   try{n=o()}
                   catch(a){$.ajax("/domestic/cas/image/bi"
                       ,{method:$.AJAX_METHOD_POST,cache:!1,context:{value:"11-"+encodeURIComponent(a.stack||a)}})
                   }
                   finally{i=!0,e.resolve(n)}
 }
 ,$.loader.js(n,{onload:function(){i||(window[t]=void 0,e.reject(""))},onerror:function(o){o&&(window[t]=void 0),e.reject("")}})

}
