python使用selenium模拟操作Chrome浏览器

1、安装selenium

pip install selenium

2、打开浏览器登录获取cookie

from selenium import webdriver
import time
import json


driver = webdriver.Chrome()     # 创建Chrome对象.

# 操作这个对象.
driver.get('https://baidu.com')     # get方式访问
time.sleep(5)

el = driver.find_element_by_xpath("//input[@type='text']")
el.send_keys('***********')
time.sleep(2)
el = driver.find_element_by_xpath("//input[@type='password']")
el.send_keys('*****')
time.sleep(2)

el = driver.find_element_by_id("submit-login")
el.click()
time.sleep(2)

#获取网站cookie
diccookie=driver.get_cookies()
fw=open('cookie.txt','w')
json.dump(diccookie,fw)
fw.close()

#driver.get_screenshot_as_file('foo.png')
time.sleep(10)
#driver.quit()   # 使用完, 记得关闭浏览器, 不然chromedriver.exe进程为一直在内存中.

3、读取使用cookie：

from selenium import webdriver
import time
import json


driver = webdriver.Chrome()     # 创建Chrome对象.

driver.get('https://mp.qutoutiao.net')          
fr=open('cookie.txt','r')
cookielist=json.load(fr)
fr.close()
for cookie in cookielist:
    driver.add_cookie(cookie)
# 操作这个对象.
driver.get('https://mp.qutoutiao.net')     # get方式访问
time.sleep(1)

#driver.get_screenshot_as_file('foo.png')
#time.sleep(10)
#driver.quit()   # 使用完, 记得关闭浏览器, 不然chromedriver.exe进程为一直在内存中.

4、登录完成，开始干活

#-*-coding:utf-8-*-
from selenium import webdriver
import time
import json


driver = webdriver.Chrome()     # 创建Chrome对象.
driver.maximize_window()
# 操作这个对象.
driver.get('https://mp.***.net')     # get方式访问
time.sleep(5)

el = driver.find_element_by_xpath("//input[@type='text']")
el.send_keys('****')
time.sleep(2)
el = driver.find_element_by_xpath("//input[@type='password']")
el.send_keys('*****')
time.sleep(2)

el = driver.find_element_by_id("submit-login")
el.click()
time.sleep(2)

#获取网站cookie
diccookie=driver.get_cookies()
fw=open('cookie.txt','w')
json.dump(diccookie,fw)
fw.close()

el = driver.find_element_by_class_name("shadow-close")
el.click()
time.sleep(2)

#滚动到浏览器顶部
js_top = "var q=document.documentElement.scrollTop=0"
#滚动到浏览器底部
js_bottom = "var q=document.documentElement.scrollTop=10000"
js_bottom2 = "window.scrollTo(0,document.body.scrollHeight)"

driver.execute_script(js_top)

el = driver.find_element_by_class_name("sub-child-txt")
el.click()
time.sleep(2)

el = driver.find_element_by_xpath('//div[@class="content-header"]/div/p[3]')
el.click()
time.sleep(2)
#article 图文1,3 video视频2,4
el = driver.find_element_by_xpath('//div[@class="content-article"]/div/p[4]')
el.click()
time.sleep(2)

for i in range(1,100):
    try:
        el = driver.find_element_by_class_name("icon-delete")
        el.click()
        time.sleep(2)

        el = driver.find_element_by_class_name("el-button--primary")
        el.click()
        time.sleep(2)
        #driver.refresh()
    except:
        pass
    

#print(txt)

#driver.get_screenshot_as_file('foo.png')
time.sleep(10)
#driver.quit()   # 使用完, 记得关闭浏览器, 不然chromedriver.exe进程为一直在内存中.
