【selenium】selenium和requests登陆的区别

requests登陆

import requests
import time
t = int(time.time()*1000)
# 创建一个会话
s = requests.Session()
post_url = 'http://account.chinaunix.net/login/login'
data = {
    'username': 'xxxxxxxxx',
    'password': 'xxxxxxxxx',
    '_token': 'nmSXhgHib8dTIC9DrATSkTzBBo4zz9eqDEPeG5i1',
    '_t': t
}
r = s.post(url=post_url, data=data,allow_redirects=False)
r = s.get('http://bbs.chinaunix.net/')
with open('chinaunix.html', 'w') as fp:
    fp.write(r.text)

selenium登陆

from selenium import webdriver
import  time
url = 'http://bbs.chinaunix.net/member.php?mod=logging&action=login&logsubmit=yes'

webdriver = webdriver.Chrome()


webdriver.get(url=url)

time.sleep(15)


webdriver.find_element_by_name('username').send_keys('xxxxxxxxx')

webdriver.find_element_by_name('password').send_keys('xxxxxxxxx')

webdriver.find_element_by_name('loginsubmit').click()

time.sleep(15)

with open('chinaunixselenium.html','w',encoding='utf-8') as fp:
    fp.write(webdriver.page_source)

使用Selenium
需要安装：pip install selenium
