在Python中使用类参数作为函数装饰器

class Decorator:
    def __init__(self, arg1, arg2):
        # 初始化装饰器参数
        self.arg1 = arg1
        self.arg2 = arg2

    def __call__(self, func):
        # 定义装饰器的行为
        def wrapper(*args, **kwargs):
            # 在函数调用前执行的操作
            print("Decorator arguments:", self.arg1, self.arg2)
            # 调用被装饰的函数
            result = func(*args, **kwargs)
            # 在函数调用后执行的操作
            print("Decorator finished")
            return result

        return wrapper

@Decorator("param1", "param2")
def my_function():
    print("Hello, world!")

my_function()

Decorator arguments: param1 param2
Hello, world!
Decorator finished
