大话设计模式
设计模式——代理模式
代理模式(Proxy Pattern):为其他对象提供一种代理以控制对这个对象的访问
实现:戴励 替 卓贾易 送礼物给 娇娇
模型:
#公共接口类
class InterFace:
  def request(self):
    pass
#真实类
class RealSubject(InterFace):
  def request(self):
    print 'RealSubject request'
#代理类 调用真实类的内部方法
class ProxySubject(InterFace)
  def request(self):
    self.real = RealSubject()
    self.real.request()
