$ scope可在get call之外访问。由于AJAX调用的异步性，控制台不得显示​​更新的数据。

您可以尝试更新以下功能

angular.module('finalApp').controller('WarningsCtrl', function ($scope,HttpService) {
  var getSnowStromeWarning = function(callback) {
        HttpService.get('/warings/snowstrome').error(function(data){
        data={
         ...   
        };
        $scope.liveCards=data;
        callback();
    });
   }  
   getSnowStromeWarning(function(){
       console.log($scope.liveCards)
   });
});
