如何解析Ruby中的JSON响应

使用import.io,我构建了一个端点来查询我提供此响应的天气服务：

{"extractorData"=>
  {"url"=>
    "https://www.aviationweather.gov/metar/data?ids=kokb&format=decoded&hours=0&taf=off&layout=on&date=0",
   "resourceId"=>"66ca907842aabb6b08b8bc12049ad533",
   "data"=>
    [{"group"=>
       [{"Timestamp"=>[{"text"=>"Data at: 2135 UTC 12 Dec 2016"}],
         "Airport"=>[{"text"=>"KOKB (Oceanside Muni, CA, US)"}],
         "FullText"=>
          [{"text"=>
             "KOKB 122052Z AUTO 24008KT 10SM CLR 18/13 A3006 RMK AO2 SLP179 T01780133 58021"}],
         "Temperature"=>[{"text"=>"17.8°C ( 64°F)"}],
         "Dewpoint"=>[{"text"=>"13.3°C ( 56°F) [RH = 75%]"}],
         "Pressure"=>
          [{"text"=>
             "30.06 inches Hg (1018.0 mb) [Sea level pressure: 1017.9 mb]"}],
         "Winds"=>
          [{"text"=>"from the WSW (240 degrees) at 9 MPH (8 knots; 4.1 m/s)"}],
         "Visibility"=>[{"text"=>"10 or more sm (16+ km)"}],
         "Ceiling"=>[{"text"=>"at least 12,000 feet AGL"}],
         "Clouds"=>[{"text"=>"sky clear below 12,000 feet AGL"}]}]}]},
 "pageData"=>
  {"resourceId"=>"66ca907842aabb6b08b8bc12049ad533",
   "statusCode"=>200,
   "timestamp"=>1481578559306},
 "url"=>
  "https://www.aviationweather.gov/metar/data?ids=kokb&format=decoded&hours=0&taf=off&layout=on&date=0",
 "runtimeConfigId"=>"2ddb288f-9e57-4b58-a690-1cd409f9edd3",
 "timestamp"=>1481579246454,
 "sequenceNumber"=>-1}

我似乎遇到了两个问题.我如何能：

>拉出每个字段并将其写入自己的变量
>忽略响应中的“text”修饰符.

require 'json'

foo = JSON['{"a":1}']
foo # => {"a"=>1}

JSON足够聪明,可以查看参数,并根据它是字符串还是数组或哈希,解析或序列化它.在上面的例子中,它将其解析为哈希.

从那时起,普通的Ruby需要深入了解您返回的哈希并访问特定值：

foo = JSON['{"a":1, "b":[{"c":3}]}']
foo # => {"a"=>1, "b"=>[{"c"=>3}]}
foo['b'][0]['c'] # => 3

如何浏览哈希在互联网和Stack Overflow上进行了广泛的讨论,因此请搜索并查看您可以找到的内容.
