用selenium获取cookies

前言：由于登录反爬措施的越来越麻烦，甚至出现了12306这种看图识物的无敌验证码，我只能说，我选择死亡。这就衍生出了使用selenium来获取获取cookies。

实例：获取qq空间cookies，亲测成功2018-3-7（注意点：chromedriver.exe的路径输入）

　　from selenium import webdriver
　　import requests
　　import json
　　import time

 1　def get_cookies():
     browser = webdriver.Chrome(executable_path="D:\SeleniumDemo-master\chromedriver.exe")
     browser.get("https://user.qzone.qq.com/xxx/infocenter")# xxx 改为qq账号
     input("请登陆后按Enter")
     #print(browser.get_cookies())
     cookie={}
     for i in browser.get_cookies():
         cookie[i["name"]] = i["value"]
     with open("cookies.txt","w") as f:
         f.write(json.dumps(cookie))
     # time.sleep(5)
     # button = browser.find_element_by_xpath('//*[@id="switcher_plogin"]')
     # button.click()

     #browser.close()
 def get_content():
     user_agent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36"
     with open("cookies.txt","r")as f:
         cookies = f.read()
         cookies = json.loads(cookies)
     session = requests.session()
     html = session.get("https://user.qzone.qq.com/xxx/infocenter",headers={"User-Agent":user_agent},cookies=cookies) # xxx改为qq账号
     print(html.text)

 if __name__ == "__main__":
　　　　get_cookies()
　　　　get_content()

cookies一保存，至少短期内是可以省下登录的时间。

改进：(自动填写账号密码)

 def get_cookies():
     """获取cookies保存为txt"""
     browser = webdriver.Chrome(executable_path="D:\SeleniumDemo-master\chromedriver.exe")
     browser.get("https://user.qzone.qq.com/")

     #input("请登陆后按Enter")
     browser.switch_to.frame("login_frame")
     button = browser.find_element_by_css_selector('#switcher_plogin')
     button.click()
     account = browser.find_element_by_css_selector("#u")
     account.clear()
     account.send_keys("") #此处写账号

     password = browser.find_element_by_css_selector("#p")
     password.clear()
     password.send_keys("") #此处写密码

     login_button = browser.find_element_by_css_selector("#login_button")
     login_button.click()
     #print(browser.get_cookies())

     cookie={}
     for i in browser.get_cookies():
         cookie[i["name"]] = i["value"]
     with open("cookies.txt","w") as f:
         f.write(json.dumps(cookie))
     input()
     #browser.close()
