Python 实现模拟登录和爬取动态网页中的数据分析方法

import requests

login_url = 'https://www.zhihu.com/login/email'
data = {
    'email': 'your_email',
    'password': 'your_password',
}
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36',
}

session = requests.session()
r = session.post(login_url, data=data, headers=headers)

# 输出登录成功后的页面源代码
print(r.text)

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

# 启动 Chrome 浏览器
driver = webdriver.Chrome()

# 打开知乎用户页面
url = 'https://www.zhihu.com/people/zhang-jia-wei/followers'
driver.get(url)

# 获取登录按钮
login_btn = driver.find_element_by_css_selector('.PageHeader-menu .Button--blue')
login_btn.click()

# 输入登录信息
username = driver.find_element_by_name('username')
password = driver.find_element_by_name('password')
username.send_keys('your_email')
password.send_keys('your_password')
password.send_keys(Keys.RETURN)

# 等待登录成功并获取页面源码
import time
time.sleep(10)
html = driver.page_source

# 输出页面源码
print(html)
