網(wǎng)頁動態(tài)產(chǎn)生JS，但是這個JS里有POST必要參數(shù)，這該如何解決？

1.去哪兒搜索機(jī)票時有一個es參數(shù)，如下圖
圖片描述

2.然后查到這個參數(shù)由一個js文件產(chǎn)生，如下圖：
圖片描述

這個名稱和時間戳一樣的js文件就是產(chǎn)生這個參數(shù)的代碼
3.這個文件經(jīng)過比較簡單的加密，我破解出來產(chǎn)生參數(shù)的主要代碼為：

當(dāng)然隨著時間還是會變的，而且這個文件是我好幾天前復(fù)制過來破解的。并且我用破解的js產(chǎn)生的文件不能作為查詢機(jī)票的es參數(shù)。

4.但是當(dāng)我們重新搜索時，如下圖
圖片描述

5.這個js文件名稱變化了，我再度破解后，發(fā)現(xiàn)里面雖然變量名全變了，但是大多數(shù)代碼結(jié)構(gòu)和我之前的是類似的，而且的確其中一些參數(shù)變化了。

6.最后我就想問下如何應(yīng)對這種連JS都動態(tài)變化的網(wǎng)站？
