Python3 實現帶cookie登陸網站--自動

 

 

from urllib import request, parse
from http import cookiejar

# 創建cookiejar的實例
cookie = cookiejar.CookieJar()
# 生成cookie的管理器
cookie_handler = request.HTTPCookieProcessor(cookie)
# 創建http請求管理器
http_handler = request.HTTPHandler()

# 生成https管理器
https_handler = request.HTTPSHandler()

# 創建請求管理器
opener = request.build_opener(http_handler, https_handler, cookie_handler)


def login():
    '''
     負責初次登陸
     需要輸入用戶名密碼，用來過去登陸cookie憑證
    '''

    # 此url需要從登陸from的action屬性中提取
    url = 'http://www.renren.com/PLogin.do'

    # 鍵值需要從登陸from的兩個對應input中提取name屬性
    data = {
        'email': "185807487xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
        'password': 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
    }

    # 把數據進行編碼
    data = parse.urlencode(data)

    # 創建一個請求對象
    req = request.Request(url, data=data.encode())

    # 使用openner發起請求
    opener.open(req)



def getHomepage():
    url = 'http://www.renren.com/974598244/profile'

    # 如果已經執行了login函數，則opener自己已經包含了對應的cookie值
    rsp = opener.open(url)
    html = rsp.read().decode()
    with open("rsp.html", 'w', encoding='utf-8') as f :
        f.write(html)

if __name__ == '__main__':
    login()
    getHomepage()
