sns什么的我是一直無愛的，這次蛋疼寫了個登錄開心網(wǎng)(kaixin001)并向所有好友發(fā)送站內消息的腳本。
開心網(wǎng)在登錄的時候做了一些處理，并不傳原始密碼，從js分析到的結果是：登錄時會生成一個隨機的key，然后用這個key和原始密碼進行xxtea加密，把加密后的結果再進行sha1加密。之后post這個key以及加密后的密碼進行登錄驗證。
以下是很簡陋的腳本內容：

操作kaixin001，現(xiàn)有方法：
get_login_key － 獲得用戶訪問登錄頁面時分配的加密key
get_rpassword － 獲得經(jīng)過xxtea以及sha1加密后的密碼
login - 登錄
get_friends_list - 獲得所有好友，返回字典格式
