selenium登入獲取cookie

get_cookie_by_selenium.py

import pickle
import time
from selenium import
 
 webdriver


def get_cookies():
    url = 'https://www.test.com'
    web_driver = webdriver.Chrome()
    web_driver.get(url)

    username = web_driver.find_element_by_id('login-email')
    username.send_keys('username')
    password = web_driver.find_element_by_id('login-password')
    password.send_keys('password'
 
)
    login_button = web_driver.find_element_by_id('login-submit')
    login_button.click()
    time.sleep(3)
    cookies = web_driver.get_cookies()
    web_driver.close()
    return cookies


if __name__ == '__main__':
    cookies = get_cookies()
    pickle.dump(cookies, open('cookies.pkl', 'wb'))

獲取瀏覽器cookie(以Ubuntu的Firefox為例)

get_cookie_by_firefox.py

import sqlite3
import pickle


def get_cookie_by_firefox():
    cookie_path = '/home/name/.mozilla/firefox/bqtvfe08.default/cookies.sqlite'
    with sqlite3.connect(cookie_path) as conn:
        sql = 'select name,value from moz_cookies where baseDomain="test.com"'
        cur = conn.cursor()
        cookies = [{'name': name, 'value': value} for name, value in cur.execute(sql).fetchall()]
        return cookies


if __name__ == '__main__':
    cookies = get_cookie_from_firefox()
    pickle.dump(cookies, open('cookies.pkl', 'wb'))

scrapy使用獲取後的cookie

cookies = pickle.load(open('cookies.pkl', 'rb'))
yield scrapy.Request(url, cookies=cookies, callback=self.parse)

requests使用獲取後的cookie

cookies = pickle.load(open('cookies.pkl', 'rb'))
s = requests.Session()
for cookie in cookies:
    s.cookies.set(cookie['name'], cookie['value'])

selenium使用獲取後的cookie

from selenium import webdriver
cookies = pickle.load(open('cookies.pkl', 'rb'))
w = webdriver.Chrome()

# 直接新增cookie會報錯，下面是一種解決方案，可能有更好的
# -- start --
w.get('http://www.test.com')
w.delete_all_cookies()
# -- end --

for cookie in cookies:
    w.add_cookie(cookie)
