js提取新浪郵箱的信用卡

js提取使用者新浪郵箱中的信用卡資訊，是js非nodejs。

對比py，之前就做不好，出現了複雜點選驗證碼。js的開發速度隻需要py的三分之一，甚至十分之一。

js在用戶端執行，py在後端執行，py要實作實時高并發，在應對2000個并發時候，需要買幾百台伺服器。js節約這些錢。如果某一步使用了selenium需要上千台伺服器。

可以登入後打開郵箱頁面時候，執行這個來測試。就能擷取到别人的資訊了。實際是app。

一定是要在新浪郵箱頁面打開console控制台，不能在别的網站打開console執行下面的代碼，否則是跨域的，請求不到，要不然開發者在自己網站的js腳本寫個ajax，請求淘寶 支付寶的網站api，然後把結果傳到背景，你的資訊都被别人知道了，這是不可能做到的。
