基礎的裝飾器：

#!/usr/bin/env python
# -*- coding:utf-8 -*-
username,password = "sunwei","123"

def auth(func):
    def wrapper():
        user = input("please input your name：").strip()
        passwd = input("please input your password：").strip()
        if user == username and passwd == password:
            
 
print("\033[32;40m驗證通過\033[0m")
            func()
        else:
            print("\033[31;40m驗證失敗\033[0m")
    return wrapper

@auth
def test1():
    print("welcome to test1...")
@auth
def test2():
    print("welcome to test2...")
test1()
test2()

升級一下，裝飾器函數帶參數....

#!/usr/bin/env python
# -*- coding:utf-8 -*-
 

import time
username,password = "sunwei","123"


def auth(auth_type):
    def out_wrapper(func):
        def wrapper(*args,**kwargs):
            if auth_type == "local": 
                user = input("please input your name：").strip()
                passwd = input("please input your password：").strip()
                
 
if user == username and passwd == password:
                    print("\033[32;40m驗證通過\033[0m")
                    func(*args,**kwargs)
                else:
                    print("\033[31;40m驗證失敗\033[0m")
            else:
                time.sleep(3)
                exit("我不知道什麽是ldap...")
        return wrapper
    return out_wrapper

@auth(auth_type = "local") #test1 = auth(test1)
def test1():
    print("welcome to test1...")
@auth(auth_type = "ldap")
def test2():
    print("welcome to test2...")
test1()
test2()
