Question

我有以下JSON响应。在这个JSON中，我有＆＃34;结果＆＃34;作为JSON数组。从这个数组我想检索并显示每个实例名称的值和相应的状态。我怎么能这样做？

    "oraDBHost" : "",

require 'json'
JSON.parse(input)['result'].map do |h|
  [h['instanceName'], h['status']]
end.to_h
#⇒ {
#      "920_ENT_6017" => "RUNNING",
#      "920_JAS_8082" => "RUNNING",
#          "AIS_0005" => "RUNNING",
#  "DEN00KNL_DEP_920" => "RUNNING",
#           "ENT6547" => "STOPPED",
#         "HTML_8792" => "RUNNING",
#          "RTE_0004" => "RUNNING",
