从Hash获取值

Question

我有值response_data存储这些数据：

{"response_data"=>
  {"transaction_type"=>"void",
   "status"=>"error",
   "unique_id"=>"ec8b1e786efe64f667ad19ff1b39fb92",
   "transaction_id"=>"kcyplptlpk966yifmuct6jj0od",
   "code"=>"410",
   "technical_message"=>"no approved reference transaction found",
   "message"=>"Something went wrong, please contact support!",
   "mode"=>"test",
   "timestamp"=>"2017-11-24T08:07:40Z",
   "descriptor"=>"rwgwg",
   "sent_to_acquirer"=>"false"}}

我如何从这个结构中获取密钥？

showChildModal(): void { //Mehtod to fire the popup
this.parentModal.show();
 }

ngOnInit() {
let mapProp = {
  center: { lat: 30.42018, lng: -9.5981500 },

  zoom: 5,
  mapTypeId: google.maps.MapTypeId.ROADMAP
};
this.map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
 }
