大神啊！如何用HTTP请求调用网页中的脚本啊！神er

大神们，我现在想做一个东西，就是要在百度网盘上下载东西，手动下载的时候要点击两个按钮，我用程序怎么实现这两次点击呢？应该向着哪个方向解决这个问题呢，神er。

我看了下html代码，里面是调用的JS，JS又调用了别的什么玩意，这个是点击第一个按钮的click触发代码，第二个按钮在静态的HTML上找不到啊，神啊，出来吧！！
function(B){
var A=disk.util.ViewShareUtils.viewShareData,_=null;
try{
=$.parseJSON(A);
}
catch(C)
{}
if(!=null)
{
disk.util.ViewShareUtils.downloadShareFile([_],$(this).attr("href"));
}
else{
disk.util.ViewShareUtils.useToast(disk.ui.Toast.MODE_CAUTION,"\u670d\u52a1\u5668\u9519\u8bef\uff0c\u8bf7\u7a0d\u5019\u91cd\u8bd5",false);
}
B.preventDefault();
return false;
}

哎，哥们搞定了，后来者借鉴下吧，用的是HtmlUnit，下面是在百度输入“小时代”然后取回结果的代码。
