来自专栏 · Python设计模式 1 人赞同了该文章 代理模式(Proxy Pattern)是一种结构型设计模式,它允许使用代理对象来控制对另一个对象(即主题对象)的访问。代理模式可以在不改变对象的代码的情况下,为对象添加额外的功能,例如延迟初始化、访问控制、日志记录、事务管理等。 代理模式的主要角色 主题(Subject):定义了真实对象和代理
Python 中万 物皆对象,自省指代码可以查看内存中以对象形式存在的其它模块和函数,获取它们的信息,并对它们进行操作。 利用这种方法,你可以定义没有名称的函数,不按函数声明的参数顺序调用函数,甚至引用事先并不知道名称的函数(getattr)。 " 1#: c04:ProxyDemo2.py 2 3#Simple demonstration of the Proxy patter...
Note that monkeypatching may not work for all standard modules or for all third party modules, and generally isn't recommended. Monkeypatching is usually an anti-pattern in Python. Original SocksiPy README attached below, amended to reflect API changes. ...

3. Client Class: The client class accesses the proxy, which in turn accesses the real subject. The following is an example implementation of the proxy pattern: ```python # Real Subject class RealSubject: def __init__(self, name): self.name = name def request(self): print(f'RealSubject...
A proxy can act as an intermediary between your Javascript and the remote data, eliminating all the cross domain limitations imposed on the client. The pattern in principle is simple: Assign to your web application's server some view to receive a request with a parameter of the desired remote...
