前些年寫過這個登入程式，過了幾年系統有所升級，於是做了一定的修改。

新版本的校園網登入程式依然是模擬瀏覽器去登入校園網。

Python3.7編寫。

#encoding:UTF-8
from urllib.parse import urlencode
from urllib.request import urlopen
import urllib
import os
import sys
import getpass

if __name__ == "__main__":
    #username=input("please input your username\nUsername: ")
 

    #print "please input your password"
    #password=getpass.getpass()
    username = "123456"
    password = "123456"
    
    
    opener=urllib.request.build_opener(urllib.request.HTTPRedirectHandler(), urllib.request.HTTPHandler(debuglevel=0))
    opener.addheaders=[('User-agent', "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
 
")]
    url='http://172.20.20.1:801/srun_portal_pc.php?ac_id=3&'
    
    try:
        response=opener.open(url, urlencode({"ac_id":"3", "action":"login", "nas_ip":"", "password":password, "save_me":"1", "url":"", "user_ip":"", "user_mac":"", "username":username }).encode("utf-8"))

        xxx_print 
 
= response.read().decode("utf-8")

        if xxx_print.find(u'網路已連線') != -1:
            print( '\n\n\n' )
            print( '##################################' )
            print( '您已經成功登入' )
            print( '##################################' )
            print( '\n\n\n' ) 
        else:
            print( '\n\n\n' )
            print( '##################################' )
            print( '抱歉，您登入失敗' )
            print( '##################################' )
            print( '\n\n\n' )
            print( xxx_print )
    except Exception as e:
        print( '\n\n\n' )
        print( '##################################' )
        print( "網路聯通有誤， 請檢測網路是否可達"  )
        print( '##################################' )
        print( e )

最後，成功登入。
