一、导入模块

import urllib.requestimport http.cookiejarimport urllib.parseimport sslssl._create_default_https_context = ssl._create_unverified_context

二、依次创建cookiejar对象、handler对象、opener对象

cookie = http.cookiejar.CookieJar()handler = urllib.request.HTTPCookieProcessor(cookie)opener = urllib.request.build_opener(handler)

三、模拟登录数据

获取登录表单的提交地址

post_url = 'https://passport.weibo.cn/sso/login'

查看表单提交字段，设计模拟数据

data = {    'username':'18570329382',    'password':'1126482',    'savestate':'1',    'r':'http://weibo.cn/',    'ec':'0',    'pagerefer':'',    'entry':'mweibo',    'wentry':'' ,    'loginfrom':'',    'client_id':'',    'code':'',    'qq':'',    'mainpageflag':'1',    'vid':'fef0ad08eb4bf0b3e04a026f8778705614f877870561',    'hff':'',    'hfp':'',}data = urllib.parse.urlencode(data).encode('utf-8')

构造headers

headers = {    'Host': 'passport.weibo.cn',    'Connection':'keep-alive',    'Content-Length':'219',    'Origin':'https://passport.weibo.cn',    'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_1) AppleWebKit/537.36 (KHTML like Gecko) Chrome/63.0.3239.84 Safari/537.36',    'Content-Type': 'application/x-www-form-urlencoded',    'Accept':'*/*',    'Referer':'https://passport.weibo.cn/signin/login?entry=mweibo&r=http%3A%2F%2Fweibo.cn%2F&backTitle=%CE%A2%B2%A9&vt=',    'Accept-Encoding':'gzip, deflate, br',    'Accept-Language':'zh-CN,zh;q=0.9',    }

四、模拟请求

request = urllib.request.Request(url=post_url,data=data,headers=headers)

五、发送请求进行登录

response = opener.open(request)

六、用opener对象访问登录后的详情页（opner对象自动保存了登录后的cookies)

url = 'https://weibo.cn/5613030371/info'headers1 = {    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_1) AppleWebKit/537.36 (KHTML like Gecko) Chrome/63.0.3239.84 Safari/537.36',}request = urllib.request.Request(url=url,headers=headers1)response1 = opener.open(request)print(response1.read())
