學(xué)習(xí)通是大家經(jīng)常使用的工具，里面也有許多功能，不過都需要登錄才能使用，所以逆向登錄就很有必要了。

首先我們來分析一下登錄數(shù)據(jù)。

?

?我們發(fā)現(xiàn)uname和password都是加密的，我們重新發(fā)送一個(gè)新的登錄請(qǐng)求發(fā)現(xiàn)，雖然是加密但是加密結(jié)果是不會(huì)變的，那么登錄就變得輕而易舉了。當(dāng)我們帶上參數(shù)，用程序發(fā)送請(qǐng)求時(shí)，發(fā)現(xiàn)登錄失敗。到底是什么原因呢，小編使用fd抓包工具抓取瀏覽器的請(qǐng)求和程序的請(qǐng)求對(duì)比。

發(fā)現(xiàn)瀏覽器上看到的請(qǐng)求頭和發(fā)送的請(qǐng)求頭順序不同，那么小編按照該請(qǐng)求頭請(qǐng)求，最后成功請(qǐng)求。?
