Python爬蟲初學（3）登陸武漢理工大學教務處

cookie還是不太懂，登陸了教務處主頁後，查成績用的另一個header，所以總是登陸超時

import urllib.parse,urllib.request,http.cookiejar,os

#cookie處理，照抄
cookie = http.cookiejar.CookieJar() 
cookieProc = urllib.request.HTTPCookieProcessor(cookie) 
opener = urllib.request.build_opener(cookieProc) 
urllib.request.install_opener(opener)                        #全局的opener

postdata=urllib.parse.urlencode({
    'systemId':'',
    'xmlmsg':'',
    'userName':'012130494XXXX',
    'password':'012130494XXXX',
    'type':'xs',
	'imageField.x':'60',
	'imageField.y':'19'
}).encode(encoding='UTF8')

#似乎是在header帶入了驗證，所以只能照抄
headers = {
    'User-Agent':'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0',

	'Connection':'keep=alive'
}

req = urllib.request.Request(
    url = 'http://sso.jwc.whut.edu.cn/Certification/login.do',
    data = postdata,
    headers = headers
)

result = urllib.request.urlopen(req).read().decode("utf-8")
print(result)	

os.system('pause')
