一、匯入模組

import urllib.request
import http.cookiejar
import urllib.parse
import ssl

ssl._create_default_https_context = ssl._create_unverified_context

二、依次建立cookiejar物件、handler物件、opener物件

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

三、模擬登入資料

• 獲取登入表單的提交地址

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

• 查看錶單提交欄位，設計模擬資料

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')

• 構造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、模擬請求

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

五、傳送請求進行登入

response = opener.open(request)

六、用opener物件訪問登入後的詳情頁（opner物件自動儲存了登入後的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())
