大神啊！如何用HTTP請求調用網頁中的腳本啊！神er

大神們，我現在想做一個東西，就是要在百度網盤上下載東西，手動下載的時候要點擊兩個按鈕，我用程序怎麼實現這兩次點擊呢？應該向著哪個方向解決這個問題呢，神er。

我看了下html代碼，裡面是調用的JS，JS又調用了別的什麼玩意，這個是點擊第一個按鈕的click觸發代碼，第二個按鈕在靜態的HTML上找不到啊，神啊，出來吧！！
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，哥們搞定了，後來者借鑒下吧，用的是HtmlUnit，下面是在百度輸入“小時代”然後取回結果的代碼。
