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():
 2     browser = webdriver.Chrome(executable_path="D:\SeleniumDemo-master\chromedriver.exe")
 3     browser.get("https://user.qzone.qq.com/xxx/infocenter")# xxx 改为qq账号
 4     input("请登陆后按Enter")
 5     #print(browser.get_cookies())
 6     cookie={}
 7     for i in browser.get_cookies():
 8         cookie[i["name"]] = i["value"]
 9     with open("cookies.txt","w") as f:
10         f.write(json.dumps(cookie))
11     # time.sleep(5)
12     # button = browser.find_element_by_xpath('//*[@id="switcher_plogin"]')
13     # button.click()
14 
15     #browser.close()
16 def get_content():
17     user_agent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36"
18     with open("cookies.txt","r")as f:
19         cookies = f.read()
20         cookies = json.loads(cookies)
21     session = requests.session()
22     html = session.get("https://user.qzone.qq.com/xxx/infocenter",headers={"User-Agent":user_agent},cookies=cookies) # xxx改为qq账号
23     print(html.text)
24 
25 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)

 1 def get_cookies():
 2     """获取cookies保存为txt"""
 3     browser = webdriver.Chrome(executable_path="D:\SeleniumDemo-master\chromedriver.exe")
 4     browser.get("https://user.qzone.qq.com/")
 5 
 6     #input("请登陆后按Enter")
 7     browser.switch_to.frame("login_frame")
 8     button = browser.find_element_by_css_selector('#switcher_plogin')
 9     button.click()
10     account = browser.find_element_by_css_selector("#u")
11     account.clear()
12     account.send_keys("") #此处写账号
13 
14     password = browser.find_element_by_css_selector("#p")
15     password.clear()
16     password.send_keys("") #此处写密码
17 
18     login_button = browser.find_element_by_css_selector("#login_button")
19     login_button.click()
20     #print(browser.get_cookies())
21 
22     cookie={}
23     for i in browser.get_cookies():
24         cookie[i["name"]] = i["value"]
25     with open("cookies.txt","w") as f:
26         f.write(json.dumps(cookie))
27     input()
28     #browser.close()
