localstorage key undefined in angularjs

Question

This is my service :

.factory('$localstorage', ['$window', function($window) {
  return {
    set: function(key, value) {
      $window.localStorage[key] = value;
    },
    get: function(key, defaultValue) {
      return $window.localStorage[key] || defaultValue;
    },
    setObject: function(key, value) {
      $window.localStorage[key] = JSON.stringify(value);
    },
    getObject: function(key) {
      return JSON.parse($window.localStorage[key] || '{}');
    }
  }
}]);

and I want to store my json into it so I do like below in my controller:

$localstorage.set(JSON.stringify($scope.data));

I use this extension https://chrome.google.com/webstore/detail/storage-area-explorer/ocfjjjjhkpapocigimmppepjgfdecjkb to check, I found that my value is undefined:

..my json did passed through, but it goes into the key, not the value. Why?

它看起来像set有一个键和一个值，而您只是设置第一个参数是键？

$localstorage.set('yourKey', JSON.stringify($scope.data));
