Ruby 鲁比.METHOD_MISSING+SEND对于带有命名参数的混合参数失败

我有这个简单的Ruby 代码.它是"代理模式"的实现.在最后一行出现故障

class ExecuteProxy
    def initialize(controller_object)
      @controller_object = controller_object
    end

    def method_missing(method, *args)
      args.empty? ? @controller_object.send(method) : @controller_object.send(method, *args)
      return
    end
end

class MyClass
    def no_arghuments
        puts "no_arghuments"
    end
    def one_argument(arg1)
        puts "one_argument #{arg1}"
    end
    def one_argument_and_named(arg1, count:1)
        puts "one_argument #{arg1} and count #{count}"
    end
end

obj = MyClass.new
proxy = ExecuteProxy.new(obj)

proxy.no_arghuments
proxy.one_argument("test")
proxy.one_argument_and_named("test2")
proxy.one_argument_and_named("test2", count:2)

输出

no_arghuments
one_argument test
one_argument test2 and count 1
test1.rb:20:in `one_argument_and_named': wrong number of arguments (given 2, expected 1) (ArgumentError)
    from test1.rb:8:in `method_missing'
    from test1.rb:31:in `<main>'

如何才能解决这个问题？如果一个方法具有普通参数+命名参数，我如何使用Send将执行传递给不同的类？

最新消息.有工作代码，答案有帮助，谢谢.

class ExecuteProxy
    def initialize(controller_object)
      @controller_object = controller_object
    end

    def method_missing(method, *args, **kw)
      @controller_object.send(method, *args, **kw)
      return
    end
end

class MyClass
    def no_arghuments
        puts "no_arghuments"
    end
    def one_argument(arg1)
        puts "one_argument #{arg1}"
    end
    def one_argument_and_named(arg1, count:1)
        puts "one_argument #{arg1} and count #{count}"
    end
    def only_named(count:, str:"")
        puts "only_named count #{count}, str: #{str}"
    end
    def manyarguments_and_named_args(arg1, arg2, arg3 = "def", count:1, some_other:"d")
        puts "manyarguments_and_named_args #{arg1}, #{arg2}, #{arg3} and count #{count}, some_other #{some_other}"
    end
end

obj = MyClass.new
proxy = ExecuteProxy.new(obj)

proxy.no_arghuments
proxy.one_argument("test")
proxy.one_argument_and_named("test2")
proxy.one_argument_and_named("test2", count:2)
proxy.only_named(count:3)
proxy.only_named(count:3,str:"string")
proxy.manyarguments_and_named_args("a1","a2")
proxy.manyarguments_and_named_args("a1","a2", "s3")
proxy.manyarguments_and_named_args("a1","a2", count:4)
proxy.manyarguments_and_named_args("a1","a2", count:4, some_other:nil)

输出

no_arghuments
one_argument test
one_argument test2 and count 1
one_argument test2 and count 2
only_named count 3, str: 
only_named count 3, str: string
manyarguments_and_named_args a1, a2, def and count 1, some_other d
manyarguments_and_named_args a1, a2, s3 and count 1, some_other d
manyarguments_and_named_args a1, a2, def and count 4, some_other d
manyarguments_and_named_args a1, a2, def and count 4, some_other
