使用python的selenium自动化登录获取cookie
要爬取广点通广告平台数据,这平台居然没有提供开发用的API数据接口,登录是QQ登录,很复杂,不好抓取登录接口逻辑
于是就用这个
想录gif的不好录 -
文档:
https://www.yiibai.com/selenium/selenium_webdriver.html
python扩展
https://pypi.org/project/selenium/
selenium的python官方手册:
https://selenium-python-zh.readthedocs.io/en/latest/index.html
代码:
#!/usr/local/bin/python# -*- coding: UTF-8 -*-
from selenium import webdriver # 从selenium导入webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.chrome.options import Options
import json
import time
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
# 不启动界面显示- linux下命令行模式必须启用
# chrome_options.add_argument('--headless')
driver = webdriver.Chrome(chrome_options=chrome_options) # Optional argument, if not specified will search path.
driver.get('http://adnet.qq.com/index') # 获取百度页面
driver.switch_to.frame('ptlogin_iframe') # 进入iframe
# 选择账号密码登录
selElement = driver.find_element_by_id('switcher_plogin')
selElement.click()
# 输入账号密码
userElement = driver.find_element_by_id('u')
pwdButton = driver.find_element_by_id('p') #密码输入框
subButton = driver.find_element_by_id('login_button') #密码输入框
userElement.send_keys("111") #输入框输入
pwdButton.send_keys("xxx") #输入框输入
subButton.click()
# 显示等待
try:
element = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.ID, "page"))
)
finally:
cookies = driver.get_cookies()
# time.sleep(5)
# driver.refresh('http://adnet.qq.com/index')
with open("cookies.txt", "w") as fp:
json.dump(cookies, fp)
# 关闭浏览器
driver.close()
很简洁吧,真真实实能解决登录这一块的问题,但是linux上环境的搭建真滴不容易
Linux环境搭建
大致流程
1、python
2、pip selenium
3、chrome brower
4、/usr/bin/chromedriver

安装chrom-linux去官网:
https://www.chrome64bit.com/index.php/google-chrome-64-bit-for-linux
下载deb文件到机器上
dpkg -i google-chrome-stable_current_amd64.deb
但是报很多的依赖问题
