如何将转换成字符串的对象，重新转换成对象。具体的就是，将 hash 对象存放到 redis 之后，再取出来，恢复成一个 hash 对象。

比如，我有一个 hash 对象 a1: 

[102] pry(main)> a123
=> {"aeopPostCategoryList"=>
  [{"id"=>3,
    "level"=>0,
    "names"=>{"zh"=>"服装/服饰配件", "pt"=>"Vestuário e acessórios", "fr"=>"Vêtements & accessoires", "en"=>"Apparel & Accessories", "ru"=>"Одежда и аксессуары", "es"=>"Ropa y accesorios", "in"=>"Pakaian & aksesoris"},
    "isleaf"=>false},
   {"id"=>34,
    "level"=>0,
    "names"=>{"zh"=>"汽车、摩托车", "pt"=>"Automóveis e motos", "fr"=>"Automobiles et motos", "en"=>"Automobiles & Motorcycles", "ru"=>"Автомобили и мотоциклы", "es"=>"Automóviles y motocicletas", "in"=>"Mobil & sepeda motor"},
    "isleaf"=>false},
   {"id"=>66, "level"=>0, "names"=>{"zh"=>"美容健康", "pt"=>"Beleza e saúde", "fr"=>"Beauté & santé", "en"=>"Beauty & Health", "ru"=>"Красоты и здоровья", "es"=>"Belleza y salud", "in"=>"Kecantikan & kesehatan"}, "isleaf"=>false},
   {"id"=>200004360,
    "level"=>0,
    "names"=>{"zh"=>"俄罗斯当地图书销售", "pt"=>"Livros locais para russo", "fr"=>"Livres pour locale russe", "en"=>"Books for Local Russian", "ru"=>"Книги для местных русский", "es"=>"Libros para Local ruso", "in"=>"Buku untuk lokal Russian"},
    "isleaf"=>false},
   {"id"=>7,
    "level"=>0,
    "names"=>{"zh"=>"电脑和办公", "pt"=>"Computador e escritório", "fr"=>"Ordinateur et bureau", "en"=>"Computer & Office", "ru"=>"Компьютер и офиса", "es"=>"Ordenador y oficina", "in"=>"Komputer & kantor"},
    "isleaf"=>false},
   {"id"=>13,
    "level"=>0,
    "names"=>
     {"zh"=>"建筑", "pt"=>"Construção & Real Estate", "fr"=>"Immobilier & Construction", "en"=>"Construction & Real Estate", "ru"=>"Строительство и недвижимость", "es"=>"Construcción y bienes raíces", "in"=>"Konstruksi & Real Estate"},
    "isleaf"=>false},
   {"id"=>44,
    "level"=>0,
    "names"=>{"zh"=>"消费电子", "pt"=>"Eletrônicos de consumo", "fr"=>"Consumer Electronics", "en"=>"Consumer Electronics", "ru"=>"Бытовая электроника", "es"=>"Electrónica de consumo", "in"=>"Elektronik konsumen"},
    "isleaf"=>false},
   {"id"=>100008578,
    "level"=>0,
    "names"=>{"zh"=>"定制化产品", "pt"=>"Produtos personalizados", "fr"=>"Produits personnalisés", "en"=>"Customized Products", "ru"=>"Настроенные продукты", "es"=>"Productos personalizados", "in"=>"Produk disesuaikan"},
    "isleaf"=>false},
   {"id"=>5,
    "level"=>0,
    "names"=>
     {"zh"=>"电气设备和产品",
      "pt"=>"Equipamentos eléctricos e suprimentos",
      "fr"=>"Electrical Equipment & Supplies",
      "en"=>"Electrical Equipment & Supplies",
      "ru"=>"Электротехника и дополнения",
      "es"=>"Equipo eléctrico y suministros",
      "in"=>"Peralatan listrik & perlengkapan"},
    "isleaf"=>false},

其存放到 redis 中，再取出来就变成这样了：

使用，JSON.parse 貌似不行。

从 redis 取出来的数据像是 a123.to_s 的结果。试试 a123.to_json 之后再存到 redis

#1 楼 @zhengpd to_json 之后，又转义了一层。

#1 楼 @zhengpd 你的意思是，to_json 之后再存，然后，使用 JSON.parse 解析。我试试。

xiajian #4 2016年03月18日

想到一个方法：Marshal.dump 对象，然后存放到 redis 中，然后，读取时是用 Marshal.load 将对象恢复出来。

jiazhen #5 2016年03月18日

同遇到过这个问题，最后还是存成了 json 用的时候再解析。Redis 是 key-value database，原则上是应该可以给任何 language 使用，不仅于 ruby

chenjau #6 2016年03月19日

对于这类我觉得 yaml 可以用。 存入 YAML.dump(目标), 取出后 YAML.load(目标).

edit: 还是用 Marshal 吧，yaml 比较之下慢一点。

yakjuly #7 2016年03月19日

你是怎么存成 string 的，就用相反的方法转换回来。

u1440247613 #8 2016年03月19日

你刚从 redis 拿出来的 直接 JSON.parse

hging #11 2016年03月20日

#10 楼 @nevermore328 你这么用然后会发现某天整个服务器都被 rm 了

xiajian #12 2016年03月21日

#7 楼 @yakjuly 存 Redis 中的，默认调用的to_s转化的。

xiajian #13 2016年03月21日

#8 楼 @u1440247613 解析报错啊，不然也不会 这么纠结：

#12 楼 @xiajian 用 to_json 或者 ActiveSupport::JSON.encode 方法存，用 ActiveSupport::JSON.decode 取

xiajian #16 2016年03月22日

#15 楼 @yakjuly

ActiveSupport 的 json 解析挺慢的：

Here's what parsing a 2.43MB JSON file off the filesystem 20 times looks like: Memory Usage Average

Yajl::Parser#parse: 32MB JSON.parse: 54MB ActiveSupport::JSON.decode: 63MB

Peak

Yajl::Parser#parse: 32MB JSON.parse: 57MB ActiveSupport::JSON.decode: 67MB

Parse Time

Yajl::Parser#parse: 4.54s JSON.parse: 5.47s ActiveSupport::JSON.decode: 64.42s

Encode Time

Yajl::Encoder#encode: 3.59s JSON#to_json: 6.2s ActiveSupport::JSON.encode: 45.58s

@xiajian 如果内容这么长都几十兆了，你要考虑下你要拿这么多内容做什么。我觉得这个设计问题就很大。
