python实现人人网的自动登录
学习了一个多星期的python,写一个自动登录人人网的脚本练习一下,我使用的版本为Python 3.2.2。
上网搜了下,有许多示例,不过基本上都是Python 2.x写的,琢磨了好久终于登录成功了,代码如下:import urllib.request import urllib.parse import http.cookiejar class LoginRenren(): def __init__(self): """log in www.renren.com""" #self.origURL = "http://www.renren.com/home" #self.domain = "renren.com" self.log_url = "http://www.renren.com/PLogin.do" self.cj = http.cookiejar.CookieJar() self.opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(self.cj)) urllib.request.install_opener(self.opener) #Installing an opener is only necessary if you want urlopen to use that opener def login(self, email, password): self.email = email self.password = password params = {"email":self.email, "password":self.password}#, "origURL":self.origURL, "domain":self.domain} params = urllib.parse.urlencode(params) params = params.encode('utf-8') #response = self.opener.open(self.log_url,params) response = urllib.request.urlopen(self.log_url, params) file = open("d:\\renren.html", "wb") file.write(response.read()) def login(email = "[email protected]", password = "mypassword" ): renren = LoginRenren() renren.login(email, password)
1.查看到登录界面的源码,获取表单内容,经过测试发现,只有email、password两项是必需的。
2.提交表单,有两个可选的函数
