使用selenium模拟登陆淘宝、新浪和知乎

如果直接使用selenium访问淘宝、新浪和知乎这些网址。一般会识别出这是自动化测试工具，会有反制措施。
当开启开发者模式后，就可以绕过他们的检测啦。

几个站模拟登陆的套路都是差不多。
麻烦一点的是知乎，老是弹出验证码。这里不提验证码的绕过，真的有大量的登录获取cookie的需求。连接打码平台应该是个不错的选择...

其实用selenium操作浏览器时尽量模拟人的操作，就可以减少验证码出现的几率了。
直接上代码吧，注释里会说明逻辑：

淘宝：

from selenium.webdriver.chrome.options import Options
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


URL = 'https://login.taobao.com/'
USER = ''
PASSWORD = ''
chrome_options = Options()  #设置
#chrome_options.add_argument('--headless')  #浏览器不提供可视化界面
chrome_options.add_argument('--disable-gpu')  #规避bug

# 设置开发者模式启动，该模式下webdriver属性为正常值   一般反爬比较好的网址都会根据这个反爬
chrome_options.add_experimental_option('excludeSwitches', ['enable-automation'])

driver = webdriver.Chrome(chrome_options=chrome_options)  #配置设置
wait = WebDriverWait(driver, 10)  #超时时长为10s
driver.get(URL)  #请求网址

#选择密码登录
login_click = wait.until(EC.presence_of_element_located((By.XPATH, '//i[@class="iconfont static"]')))
login_click.click()

#选择微博登录
weibo_click = wait.until(EC.presence_of_element_located((By.XPATH, '//a[@class="weibo-login"]')))
weibo_click.click()

#等待微博账号输入框出现
weibo_user = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.username > .W_input')))
weibo_user.send_keys(USER)

#等待微博密码输入框出现
weibo_pwd = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.password > .W_input')))
weibo_pwd.send_keys(PASSWORD)

#等待登录按钮出现

submit.click()

change.click()
# 等待知乎账号输入框出现

zhihu_user.click()

zhihu_pwd.click()
zhihu_pwd.send_keys(PASSWORD)

time.sleep(1.5)
#直接点击登录按钮
ActionChains(driver).move_by_offset(930, 500).click().perform() # 鼠标左键点击， 200为x坐标， 100为y坐标

#driver.close()
