如何从{$$ state：Object}获取数据？ [英] How to get data from {$$state: Object}?

问题描述

我尝试使用工厂从数据库中获取数据。
我有一个问题，因为我不知道如何从工厂返回的对象中获取数据。这是我在使用console.log（）函数时收到的：

I try to get data from database using factory. I have a problem, because I don't know how to get data from object which was returned from factory. This is what I received when I used console.log() function:

>d {$$state: Object}
 $$state: Object
  status: 1
  value: Array[1]
 __proto__: Object
 __proto__: Object

这是我的工厂代码：

application.factory('Database', ['$http', function($http) {
   var databaseFactory = {};
    databaseFactory.get = function(query) {
        return $http.get("getData.php", {params: {'query': query}}, {headers: {'Content-Type': 'application/x-www-form-urlencoded'}})
            .then(function (response) {
                databaseFactory.returnedData = response.data;
                return databaseFactory.returnedData;
            })
    }
    return databaseFactory;
}]);

这是我的控制器代码：

registration.controller('RegistrationController', ['$scope', 'Database', function($scope, Database) {
    $scope.posts = Database.get("SELECT * FROM `group`");
    console.log($scope.posts);
}]);

推荐答案

它正在返回一个承诺，你需要处理它这样

It's returning a promise, and you need to handle it this way

在您的控制器中添加：

getSomething.getBla().then(function(response) {

    console.log(response.data)

});
