从ruby中的方法返回匿名对象

Question

如何从ruby中的方法返回匿名对象？

在下面的代码中，我将返回一个哈希值。

  def process
    source = helper

    # I am able to get the value as an hash
    puts source[:url]
    puts source[:params]

    # But I wonder if there is a way to get it as an object, so that I can use the dot notation
    # puts source.url
    # puts source.params
  end

  def helper
    url = ''
    params = ''
    return {url: url, params: params}
  end

有什么想法。？

Answer 1

Openstruct？

require 'ostruct'

def helper
  OpenStruct.new(url: '', params: '')    
end

Answer 2

尝试一下：

def helper
  Class.new do
    def url
      ''
    end
    def params
      ''
    end
  end.new
end
