博客群发（2）--实现登陆

模板方法

python也是一种面向对象的语言，所以在实现群发的时候，会登陆不同的网站，但是登陆的方法什么的不尽相同，所以这里想到的是模板方法。

模板方法模式：

应用特性：重复做相同逻辑的事情，但是具体细节不同的场景

结构特性：相同逻辑抽取至父类，具体细节留置子类。可以说是对逻辑的抽象

看一下代码：

#!/usr/bin/env python  
#encoding: utf-8  class template:def __init__(self):passdef logic(self):print 'do something before ....'print self.do_something_now()print 'do something after ....'def do_something_now(self):return None      class apply_temp1(template):def __init__(self):passdef do_something_now(self):return 'apply 1'  class apply_temp2(template):def __init__(self):passdef do_something_now(self):return 'apply 2'  if '__main__' == __name__:  obj1 = apply_temp1()obj2 = apply_temp2()obj1.logic()obj2.logic()print obj1.__class__print obj2.__class__

得到结果如下：

然后看一下类图：

是不是很简单。

baidu登陆流程

想实现登陆baidu，使用firefox查看，可以看到如下图：

baidu HI登陆

baidu HI登陆源代码

# _*_ coding:utf-8 _*_
# name login_baidu.py
