Question

我有一个Ruby FlickRaw响应，我想将其转换为JSON。这是其结构的一部分：

#<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，我只想采用response.to_hash.to_json，但这导致以下结果：

=> "{"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>个对象而不是实际内容。所以，它只是停止在那里递归。如何让它实际输出类似我从上面的awesome_print获得的输出，其中还显示了各个照片字段？

我尝试了以下内容，它为我提供了照片数组的正确表示形式：

photos.photo.map { |h| h.to_hash  }.to_json

但这似乎相当复杂。是否可以更简单地将完整响应格式化为JSON，而无需先修复照片阵列？

显然类型FlickRaw::Response没有默认的JSON表示。

您有两种选择，可以像往常一样将照片转换为哈希值，也可以使用FlickRaw::Response方法对to_json类进行猴子修补，如

class FlickRaw::Response
  def to_json
    to_hash
  end
end

应解决问题。

转换为JSON的Ruby Hash仅显示对象名称
