如何雙擊連上校園網NCUWLAN？---bat+Python3給出了可行性答案

由於經常有小夥伴連不上南昌大學的校園網(主要是很多人打不開登錄界面)，這裏就給出一個方案，只要我們雙擊鼠標就可連接和註銷。(本方案一共有2個.py文件和2個.bat文件，需要懂一點編程，感興趣就可以往下看)

雖然校園網比較慢，可以作爲它也有神奇的地方，比如可以輕鬆越過某些牆...

下面用chrome或firefox打開登錄頁面，打不開的在地址欄輸入http://222.204.3.221:801/srun_portal_pc.php?ac_id=1&url=

然後填寫自己的學號和密碼,

fn+f12打開下面截圖的右邊視圖，選擇Network模式，

點擊登錄

點擊登錄後會出現一個報文

點擊該報文後打開了它的內容：最右邊部分

找到劃紅線的部分就是加密後的密碼(登錄校園網時密碼時經過加密的，但我發現學校其它的平臺登錄時的信息都是明文傳輸的)

將紅線處的密碼填到上面login.py的對應處，同時將學號也改過來，保存

logout.py也只要將學號和密碼改成你們自己的就行

logout.py

Demon:

經多次實測，都有效，如雙擊登錄：

註銷一樣的，雙擊logout.bat就行

最後，感興趣的同學可以自己去看下js對密碼的加密方式，這樣可以將加密方式寫入登錄腳本，直接輸學號就行，不必通過瀏覽器抓包來找到加密結果，我就不在這囉嗦了。

有什麼問題可以email我(代碼中有我的郵箱)
