[需要post的數據]

[獲取cookie]

#輸入賬號密碼的地址
loginURL = ‘http://jxpt.cuit.edu.cn/eol/homepage/common/index.jsp
 
‘
#自動記住cookie
cj = http.cookiejar.CookieJar()
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
urllib.request.install_opener(opener)# 安裝opener到全局
resp = urllib.request.urlopen(loginURL)

[post登陸]

#post數據地址
postURL = ‘http://jxpt.cuit.edu.cn/eol/homepage/common/login.jsp‘
#數據編碼
postData = urllib.parse.urlencode(postData).encode(‘utf-8‘)
#構造請求
request = urllib.request.Request(postURL, postData, headers)
#發送請求
response = urllib.request.urlopen(request)

[打印返回的信息]

#respInfo = response.info()
#接收返回的信息
html = response.read().decode(‘gb2312‘)
print(html)
print("over!")
