模拟登陆并爬取Github

因为崔前辈给出的代码运行有误,略作修改和简化了。

书上例题,不做介绍。

import requests
from lxml import etree class Login(object):
def __init__(self):
self.headers = {
'Referer': 'https://github.com/',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36',
'Host': 'github.com'
}
#登陆地址
self.login_url = 'https://github.com/login'
#POST请求地址
self.post_url = 'https://github.com/session'
#使用session保持状态,并自动处理Cookies(在访问其他子网页时,可以保持登陆,爬取网页)
self.session = requests.Session() def token(self):
#获取网页数据
response = self.session.get(self.login_url, headers=self.headers)
#提取网页中我们需要的authenticity_token并返回
selector = etree.HTML(response.text)
token = selector.xpath('//input[@name="authenticity_token"]/@value')
return token def login(self, email, password):
post_data = {
'commit': 'Sign in',
'utf8': '✓',
'authenticity_token': self.token(),
'login': email,
'password': password
}
#使用post方法模拟登陆
response = self.session.post(self.post_url, data=post_data, headers=self.headers)
#登陆正常,输出登陆后的网页代码,并将它存储带D盘github.txt
if response.status_code == 200:
print(response.text)
with open('D:/github.txt', 'w', encoding = 'utf-8') as f:
f.write(response.text)
else:
print("Error!!!") if __name__ == "__main__":
login = Login()
login.login(email='1024593536@qq.com', password='password')#输入你自己的账户密码
