我有一个RubyFlickRaw响应,希望将其转换为JSON这是它结构的一部分:

#<FlickRaw::Response:0x7fbd11088678
    @h = {
               "id" => "72157628092176654",
          "primary" => "6332013810",
            "owner" => "8623220@N02",
        "ownername" => "The Library of Congress",
            "photo" => [
            [ 0] #<FlickRaw::Response:0x7fbd1106a628
                @h = {
                           "id" => "6332007340",
                       "secret" => "4d92733d70",
                       "server" => "6217",
                         "farm" => 7,
                        "title" => "Woodrow Wilson, Twenty-Eighth President of the United States (LOC)",
                    "isprimary" => "0"
                },
                attr_reader :flickr_type = "photo"
            >,

要将其转换为JSON,我想只需使用response.to_hash.to_json,但这会导致以下结果:
=> "{"id":"72157628092176654",
"primary":"6332013810",
"owner":"8623220@N02",
"ownername":"The Library of Congress",
"photo":["#<FlickRaw::Response:0x007fbd1106a628>","#<FlickRaw::Response:0x007fbd110704d8>","#<FlickRaw::Response:0x007fbd11079c40
...

如您所见,它只输出#<FlickRaw::Response>对象,而不是实际内容所以,它就不再重复了如何让它实际输出类似于我从上面的awesome_print获得的输出,其中也显示了各个照片字段?
我尝试了以下操作,这使我获得了照片数组的正确表示:
photos.photo.map { |h| h.to_hash  }.to_json

但这似乎相当复杂有没有更简单的方法来格式化完整的响应,就像JSON一样?

最佳答案

显然,FlickRaw::Response类型没有默认的JSON表示。
您有两个选项,要么像您所做的那样将照片转换为散列,要么像中那样用FlickRaw::Response方法修补to_json

class FlickRaw::Response
  def to_json
    to_hash
  end
end

这应该能解决问题。
