# 真实的模拟浏览器，当发送完post请求的时候，将cookie保存到代码中
# 创建一个cookiejar对象
cj = http.cookiejar.CookieJar()
# 通过cookiekar创建一个handler
handler = urllib.request.HTTPCookieProcessor(cj)
# 根据handler创建一个opener
opener = urllib.request.build_opener(handler)

The above code uses the method of sending a request to simulate login. After the login is successful, use the opener you created to open all the page addresses of Renren.com that you want to visit. Once the login is successful, the authentication information in the cookie will be saved in the handler. You are always logged in!
