数据采集:selenium 提取 Cookie 自动登陆

写在前面

• 工作需要，简单整理
• 博文内容涉及 通过 selenium 实现自动登陆
• 理解不足小伙伴帮忙指正

** 对每个人而言，真正的职责只有一个：找到自我。然后在心中坚守其一生，全心全意，永不停息。所有其它的路都是不完整的，是人的逃避方式，是对大众理想的懦弱回归，是随波逐流，是对内心的恐惧 ——赫尔曼·黑塞《德米安》**

未登陆用户

保存 cookie

假设登陆用户名为 :

chinaz_7356287

我们需要获取一些

CDN

的数据，代码很简单，不做说明，自动登陆 站长之家的 CDN 网站

https://cdn.chinaz.com/

from selenium import webdriver
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
import re
import pandas as pd
import json

browser = webdriver.Chrome()
browser.get("https://cdn.chinaz.com/")
time.sleep(4)# 需要根据页面编写
browser.find_element(By.CSS_SELECTOR,".userbar").find_element(By.TAG_NAME,"a").click()print("等待登录...")whileTrue:try:
        time.sleep(10)# 需要根据页面编写 判断用户名是否存在if browser.find_element(By.CSS_SELECTOR,".username").text =="chinaz_7356287":print("已登录，保存 cookie...")withopen('cookie.txt','w', encoding='u8')as f:
            json.dump(browser.get_cookies(), f) 
            browser.close()print("cookie保存完成，游览器已自动退出...")else:
            time.sleep(3)except:passprint("登陆页面未出现，重试中")finally:pass

获取到的 JSON 数据

[{"domain":".chinaz.com","expiry":1693423590,"httpOnly":false,"name":"chinaz_topuser","path":"/","sameSite":"Lax","secure":false,"value":"92da5ff9-69ac-c0b7-73ab-040cb089d48f"},{"domain":".chinaz.com","expiry":1693884390,"httpOnly":true,"name":"ucvalidate","path":"/","sameSite":"None","secure":true,"value":"9aba1eb9-8b70-019b-8352-43ff4719eb84"},{"domain":".chinaz.com","httpOnly":false,"name":"Hm_lpvt_ca96c3507ee04e182fb6d097cb2a1a4c","path":"/","sameSite":"Lax","secure":false,"value":"1692588387"},{"domain":".chinaz.com","expiry":1724124387,"httpOnly":false,"name":"Hm_lvt_ca96c3507ee04e182fb6d097cb2a1a4c","path":"/","sameSite":"Lax","secure":false,"value":"1692588387"}]

使用 cookie 自动登陆

from seleniumwire import webdriver
import json
import time

# 自动登陆
browser = webdriver.Chrome()withopen('C:\\Users\山河已无恙\\Documents\GitHub\\reptile_demo\\demo\\cookie.txt','r', encoding='u8')as f:
    cookies = json.load(f)

browser.get('https://cdn.chinaz.com/')for cookie in cookies:
    browser.add_cookie(cookie)

browser.get('https://cdn.chinaz.com/')

time.sleep(10000)

以登陆用户

对于已经存在的用户，我们直接通过当前会话可以获取cookie 信息，然后直接替换对应的值

[{"domain":".chinaz.com","expiry":1693423590,"httpOnly":false,"name":"chinaz_topuser","path":"/","sameSite":"Lax","secure":false,"value":"92da5ff9-69ac-c0b7-73ab-040cb089d48f"},{"domain":".chinaz.com","expiry":1693884390,"httpOnly":true,"name":"ucvalidate","path":"/","sameSite":"None","secure":true,"value":"9aba1eb9-8b70-019b-8352-43ff4719eb84"},{"domain":".chinaz.com","httpOnly":false,"name":"Hm_lpvt_ca96c3507ee04e182fb6d097cb2a1a4c","path":"/","sameSite":"Lax","secure":false,"value":"1692588387"},{"domain":".chinaz.com","expiry":1724124387,"httpOnly":false,"name":"Hm_lvt_ca96c3507ee04e182fb6d097cb2a1a4c","path":"/","sameSite":"Lax","secure":false,"value":"1692588387"}]

控制台输入

console.log(document.cookie);

打印 cookie ，然后复制对应的 value 到上面的

JSON

串

console.log(document.cookie);VM64:1 toolUserGrade=DA558BECA59696EB6D6F7073658259093B6A1006BF1EE9768104ED4EF435DFFE7A7CCE826E9718B7BF5917ABBB8378EB9F2A2DF83F2D261B6ABB5FF77D3EB74948E7E207D35739840897873E9CED6A06188A7269E8D6621D2A3EB35366EE2939BD52587A8E5FD9CFD5B7FADCEA248B51B971062D27AB402FF41885786B87AD00; bbsmax_user=096a40c7-f2ba-8f87-f56a-bb8c65838157; chinaz_zxuser=c55d2eaa-e630-99a5-3d19-82c6cbadc2e3; Hm_lvt_ca96c3507ee04e182fb6d097cb2a1a4c=1692590966; Hm_lpvt_ca96c3507ee04e182fb6d097cb2a1a4c=1692590966; toolbox_urls=1.180.204.161|jiuzhoufangyuan.cn|daoxinwuliu.com|www.lzfjyl.com|lzfjyl.com|herunnongye.com|danyu.com.cn|www.danyu.com.cn|encrypt-k-vod.xet.tech; chinaz_topuser=f38f3b0f-4c0d-57d8-8f2d-35180d6e13a5

之后可以使用相同的方式登陆
