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):
        pass
    
    def 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):
        pass
    
    def do_something_now(self):
        return 'apply 1'  
    
class apply_temp2(template):
    def __init__(self):
        pass
    
    def 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：
