模板方法

python也是一種面向對象的語言，所以在實現群發的時候，會登陸不同的網站，但是登陸的方法什么的不盡相同，所以這里想到的是模板方法。

模板方法模式：

應用特性：重復做相同邏輯的事情，但是具體細節不同的場景

結構特性：相同邏輯抽取至父類，具體細節留置子類。可以說是對邏輯的抽象

看一下代碼：

#!/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__

得到結果如下：

然后看一下類圖：

是不是很簡單。

baidu登陸流程

想實現登陸baidu，使用firefox查看，可以看到如下圖：
