方法一:微博登录
1 from selenium import webdriver
2 from selenium.webdriver.common.by import By

15 options = webdriver.ChromeOptions()

17 options.add_experimental_option('excludeSwitches',
18 ['enable-automation']) # 此步骤很重要，设置为开发者模式，防止被各大网站识别出来使用了Selenium

20 self.browser = webdriver.Chrome(options=options)
21 self.wait = WebDriverWait(self.browser, 10) # 超时时长为10s
22
23 # 登录淘宝
24 def login(self):
25 # 打开网页
26 self.browser.get(self.url)
27
28 # 等待 密码登录选项 出现

方法二:保存cookie
先保存cookie
import json
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
dirver = webdriver.Chrome(options=options)
dirver.get(
'https://login.taobao.com/member/login.jhtml')
# 这里是为了等待手机扫码登录, 登录后回车即可
input("请回车登录")
dictCookies = dirver.get_cookies()
jsonCookies = json.dumps(dictCookies)
# 登录完成后,将cookies保存到本地文件
with open("./cookies_tao.json", "w") as fp:
fp.write(jsonCookies)
再次登录无需验证
1 import json
2 import time
3 from selenium import webdriver
4 from selenium.webdriver.chrome.options import Options
5
6 options = Options()
7 options.add_argument("--headless")
8 dirver = webdriver.Chrome(options=options)
9 # 初次建立连接, 随后方可修改cookie
10 dirver.get('http://www.taobao.com')
11 # 删除第一次登录是储存到本地的cookie
12 dirver.delete_all_cookies()
13 # 读取登录时储存到本地的cookie
14 with open("cookies_tao.json", "r", encoding="utf8") as fp:
15 ListCookies = json.loads(fp.read())
16
17 for cookie in ListCookies:
18 dirver.add_cookie({
19 'domain': '.taobao.com', # 此处xxx.com前，需要带点
20 'name': cookie['name'],
21 'value': cookie['value'],
22 'path': '/',
23 'expires': None
24 })
25
26 # 再次访问页面，便可实现免登陆访问
27 dirver.get("https://www.taobao.com")
28 time.sleep(3)
29 # 将页面保存为图片用于查看是否登录成功
30 dirver.save_screenshot("./taobao.png")
31 dirver.quit()
