尝试格式化从 meetup.com API 收到的一些字段。我可以获得信息，但我无法将其格式化为表格或其他易于查看的格式。

get '/ruby' do
  api_result = RestClient.get (Addressable::URI.parse('http://api.meetup.com/groups.json/?zip=14226&topic=ruby&order=members&key=XXXXXX').normalize.to_str) 
  puts api_result["name"]["city"]
end

我得到的唯一输出是空白。如果我删除 puts 行并使用 erb :meetup_table, :locals => {result: api_result}

我明白了：

JSON 数据只是一个字符串，所以你不能像散列一样使用它，除非你用它做一个散列：

http://www.ruby-doc.org/stdlib-1.9.3/libdoc/json/rdoc/JSON.html

json = RestClient.get ...
jhash = JSON.parse(json)
puts jhash['results'][0]['city'] # now we're a hash
