模拟google登录是从 https://www.cnblogs.com/bethansy/p/7683130.html 这个博客上找到的，然而一直模拟登录爬取数据比较慢的，所以我想能不能获取cookie，然后直接带入cookie参数来用python爬取

直接上代码了

#coding:utf-8
#/python3.5
__author__ = 'heart_eagle'
#第一步 获取cookie
url = 'https://www.tianyancha.com/login'

from selenium import webdriver
import os
import requests
import time
from bs4 import BeautifulSoup

chromedriver = r'C:\Program Files (x86)\Google\Chrome\Application/chromedriver.exe'
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)

driver.get(url)

# 模拟登陆
driver.find_element_by_xpath(
    ".//*[@id='web-content']/div/div/div/div[2]/div/div[2]/div[2]/div[2]/div[2]/input"). \
    send_keys('***********')    #账号
driver.find_element_by_xpath(
    ".//*[@id='web-content']/div/div/div/div[2]/div/div[2]/div[2]/div[2]/div[3]/input"). \
    send_keys('***********')    #密码
driver.find_element_by_xpath(
    ".//*[@id='web-content']/div/div/div/div[2]/div/div[2]/div[2]/div[2]/div[5]").click()
time.sleep(3)
driver.refresh()

#获取cookies
xx  = driver.get_cookies()
print(xx)
names = []
values = []

#获取cookies里对应name，和value，并形成dict
for x in xx:

    print('name:',x['name'])
    print('value',x['value'])

    names.append(x['name'])
    values.append(x['value'])

#names，values为获取的列表
#形成dict
cookies = dict(zip(names,values))

headers = {
    'Host':'www.tianyancha.com',
    'Connection':'keep-alive',
    'Cache-Control':'max-age=0',
    'Upgrade-Insecure-Requests':'1',
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36',
    'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
    'Referer':'https://www.tianyancha.com/',
    'Accept-Encoding':'gzip, deflate, br',
    'Accept-Language':'zh-CN,zh;q=0.9'



}

print(cookies)

#第二步代入参数cookie等

url = 'https://www.tianyancha.com/search'
#网址参数
params = {
    'key':'肯德基',
    'checkFrom:':'searchBox'
}

#get请求代入参数params,cookies,headers
response = requests.get(url,params = params,headers = headers,cookies = cookies, timeout = 60)

response.encoding = 'utf-8'
res = response.text
soup = BeautifulSoup(res,'html.parser')

#得到我们想要的网页
print(soup)

#....然后可以根据标签或者正则获取对应我们想要抓取的东西了，这里就不赘述了

这里是打印出来的cookies（最后一行）
