如何在TypeScript中构建可以处理多种类型的“装饰器”函数

interface Decorator {
  (target: any, propertyKey: string): PropertyDescriptor;
}

const logDecorator: Decorator = (target, propertyKey) => {
  const originalMethod = target[propertyKey];

  // 创建新的属性描述符
  const newDescriptor: PropertyDescriptor = {
    value: function (...args: any[]) {
      console.log(`Calling method ${propertyKey} with arguments: ${args}`);
      return originalMethod.apply(this, args);
    }
  };

  return newDescriptor;
};

const validateDecorator: Decorator = (target, propertyKey) => {
  const originalMethod = target[propertyKey];

  // 创建新的属性描述符
  const newDescriptor: PropertyDescriptor = {
    value: function (...args: any[]) {
      // 执行验证逻辑
      if (args.length === 0) {
        throw new Error(`Method ${propertyKey} requires at least one argument.`);
      }

      return originalMethod.apply(this, args);
    }
  };

  return newDescriptor;
};

class Example {
  @logDecorator
  @validateDecorator
  greet(name: string) {
    console.log(`Hello, ${name}!`);
  }
}

const example = new Example();
example.greet("John");
