【1】首次登录获取cookies并存为文件

from selenium import webdriver
import time
import json

br = webdriver.Chrome()
br.get("https://twitter.com/login?prefetchTimestamp=1574961630352")



# 填写手机号
user_name = br.find_element_by_css_selector('#page-container > div > div.signin-wrapper > form > fieldset > div:nth-child(2) > input')
user_name.send_keys('您的账号')


# 填写密码
password_input = br.find_element_by_xpath('//*[@id="page-container"]/div/div[1]/form/fieldset/div[2]/input')
password_input.send_keys('您的密码')


# 登陆
br.find_element_by_xpath('//*[@id="page-container"]/div/div[1]/form/div[2]/button').click()
time.sleep(5)
cookies = br.get_cookies()
# print(cookies)
with open('/Users/macbookair/Desktop/cookies-twitter.json', 'w') as f:
    self_cookies = f.write(json.dumps(cookies))

【2】从文件读取cookie并爬去目标数据



# url = 'https://twitter.com/washingtonpost/status/998271391605706752'
num=66
for url in get_links()[num:]:
    print(num)
    if "https" in url:
        print(url)
        

#         url = 'https://twitter.com/washingtonpost/status/975722353631121409'
        br = webdriver.Chrome()
        br.get("https://twitter.com")
        with open('/Users/macbookair/Desktop/cookies-twitter.json') as f:
            cookies = json.loads(f.read())
        for cookie in cookies:
            if 'expiry' in cookie:
                del cookie['expiry']
            br.add_cookie(cookie)
        br.get(url)
        # return br
        
        
        commits = set()
        get_data()
        click_more_replay()
        
        
#         js = "var b=document.getElementsByClassName('css-18t94o4 css-1dbjc4n r-1777fci r-1jayybb r-o7ynqc r-1j63xyz r-13qz1uu')"
#         br.execute_script(js)
        
        
        click_more_button()
        click_show_uncontent()


        # 实现页面下拉

        js="var q=document.documentElement.scrollTop=100000"
        for i in range(25):
            time.sleep(2)
            br.execute_script(js)
            click_more_replay()
            click_show_uncontent()
            click_more_button()
            get_data()
            # 保存数据到文件
        save_data_to_file(url,commits=get_data())
        br.quit()
    num+=1
