Ruby on rails 为什么从我的Sinatra应用程序返回的JSON会给出语法错误？

我正在开发一个Sinatra应用程序，它返回JSON，例如

  get '/clients' do

     # do stuff

     response = {
       "success" => "true",
       "msg" => "Clients successfully retrieved",
       "data" => {"clients" => @current_user.clients}
     }
     return response.to_json
  end

返回的JSON如下所示：

{"success":"true","msg":"Clients successfully retrieved","data":{"clients":[{"client":{"created_at":"2013-03-31T22:50:18Z","email":"test@test.com","first_name":"Marge","gender":"F","hairdresser_id":2,"id":1,"surname":"Simpson","updated_at":"2013-03-31T22:50:18Z"}}]}}

当我将它复制并粘贴到JSON解析器中时，它工作得很好。

但当我启动irb并尝试使用它时，我会得到一系列错误：

1.9.3-p286 :001 > a = {"success":"true","msg":"Clients successfully retrieved","data":{"clients":[{"client":{"created_at":"2013-03-31T22:50:18Z","email":"test@test.com","first_name":"Marge","gender":"F","hairdresser_id":2,"id":1,"surname":"Simpson","updated_at":"2013-03-31T22:50:18Z"}}]}}
SyntaxError: (irb):1: syntax error, unexpected ':', expecting tASSOC
a = {"success":"true","msg":"Clients success...
           ^

a = {"success":"true","msg":"Clients successfully r...
                  ^

有人能提供任何见解吗？我做错什么了吗

非常感谢你的问题 JSON并不是一个有效的Ruby，它是一个需要解析的字符串

解决方案 通过将JSON括在单引号或Ruby引号文本中，将其解析为字符串。例如：

JSON.parse %q/{"success":"true","msg":"Clients successfully retrieved","data":{"clients":[{"client":{"created_at":"2013-03-31T22:50:18Z","email":"test@test.com","first_name":"Marge","gender":"F","hairdresser_id":2,"id":1,"surname":"Simpson","updated_at":"2013-03-31T22:50:18Z"}}]}}/
=> {"success"=>"true",
 "msg"=>"Clients successfully retrieved",
 "data"=>
  {"clients"=>
    [{"client"=>
       {"created_at"=>"2013-03-31T22:50:18Z",
        "email"=>"test@test.com",
        "first_name"=>"Marge",
        "gender"=>"F",
        "hairdresser_id"=>2,
        "id"=>1,
        "surname"=>"Simpson",
        "updated_at"=>"2013-03-31T22:50:18Z"}}]}}

散列中的键值对表示为{key:value}，但ruby使用“=>”符号将键映射到值

尝试将“：”替换为“=>”，效果很好

eg) a = {"success" => "true"}

如果要将此Json解析为ruby，请使用以下代码段：

require 'json'
value = "{\"val\":\"test\",\"val1\":\"test1\",\"val2\":\"test2\"}"
puts JSON.parse(value) # => {"val"=>"test","val1"=>"test1","val2"=>"test2"}
