对JSON值进行排序？

我有一个JSON列表，如：对JSON值进行排序？

response = '{"ContainsErrors":false,"Result":[{"Name":"Aegypten","IsoCode":"EG"},{"Name":"Aequatorialguinea","IsoCode":"GQ"},{"Name":"Aethiopien","IsoCode":"ET"},{"Name":"Afghanistan","IsoCode":"AF"},{"Name":"Albanien","IsoCode":"AL"},{"Name":"Algerien","IsoCode":"DZ"},{"Name":"Angola","IsoCode":"AO"},{"Name":"Antigua und Barbuda","IsoCode":"AG"},{"Name":"Argentinien","IsoCode":"AR"},{"Name":"Australien","IsoCode":"AU"},{"Name":"Bahamas","IsoCode":"BS"}]}'

我怎样才能得到它的名字后排序？

response.sort_by { |k, v| v["Name"] }

不起作用。

什么工作是：

response = RestClient.get("#{Settings.itineris.url}/de/RepInfo/#{action}") 
#response = '{"ContainsErrors":false,"Result":[{"Name":"Aegypten","IsoCode":"EG"},{"Name":"Aequatorialguinea","IsoCode":"GQ"},{"Name":"Aethiopien","IsoCode":"ET"},{"Name":"Afghanistan","IsoCode":"AF"},{"Name":"Albanien","IsoCode":"AL"},{"Name":"Algerien","IsoCode":"DZ"},{"Name":"Angola","IsoCode":"AO"},{"Name":"Antigua und Barbuda","IsoCode":"AG"},{"Name":"Argentinien","IsoCode":"AR"},{"Name":"Australien","IsoCode":"AU"},{"Name":"Bahamas","IsoCode":"BS"}]}' 

JSON.load(response)['Result']

结果是未排序的列表。我怎样才能得到一个国家名称的有序列表？

你有一个字符串作为回应。它在操作之前，你应该把它转换为Hash：

response = '{"ContainsErrors":false,"Result":[{"Name":"Aegypten","IsoCode":"EG"}]}' 
require 'json' 
hash = JSON.parse(response)

，然后做你想做的：

hash['Result'].sort_by { |v| v["Name"] } 
#       ⇑ v here since it’s an array of hashes

要获得国名的有序列表：

hash['Result'].map { |v| v["Name"] }.sort

嗯，它不工作，所以我试着用JSON.load（response）['Result']。sort_by {| k，v | v [“Name”]}但它也失败了。 – StandardNerd

您是否注意到我在我的示例中连接了您的输入以适应页面宽度？ – mudasobwa

@Michael我使用Ruby 1.9.3，错误是“NoMethodError”和'block in rest_request'，'each'，'sort_by'... – StandardNerd
