新浪微博模拟登录，Python+RSA加密算法附源代码

首先是weiboLogin.py文件，实现一个类。

101         req  = urllib2.Request(

115             return 1
116         except:
117             print 'Login error!'
118             return 0

然后是main.py文件

 1 # -*- coding: utf-8 -*-
 2 
 3 import weiboLogin
 4 import urllib
 5 import urllib2
 6 import time
 7 
 8 filename = './config/account'#保存微博账号的用户名和密码，第一行为用户名，第二行为密码
 9 
10 WBLogin = weiboLogin.weiboLogin()
11 if WBLogin.login(filename)==1:
12     print 'Login success!'
13 else:
14     print 'Login error!'
15     exit()
