javascript - 将 json 字符串转换为随机数量的 JSON 对象内的对象

Question

我遇到了如何更改 json 对象内的 json 字符串以获取随机数量的对象的问题。让我用我的代码和评论进一步解释这一点。

我有提供 json 对象的工厂

//Factory for products
app.factory('productsFactory', ['$http', '$location', function($http, $location){
    var factory = {};
    factory.getlatestProductsList = function(n){
        return $http.get($location.protocol() + '://' + $location.host() + '/server/api/products/latest/'+n);
    }
    return factory;
}]);

该工厂返回一些随机数量的对象

问题是图像 json 是字符串格式，所以我必须使用 JSON.parse (至少我这么认为，因为我是新手)将它们转换为 JSON

我的问题是:是否有一些简单的好方法将所有图像数据解析为 json，或者我是否必须使用 forEach 来执行此操作，如果是这样，代码会是什么样子。我不想在工厂内实现这种效果，因此我不必在调用该工厂的每个 Controller 中重复代码。

如果您需要任何其他信息，请告诉我，我会提供。预先感谢您。

您可以在返回之前编辑 $http 返回的答案

app.factory('productsFactory', ['$http', '$location', function($http, $location){
    var factory = {};
    factory.getlatestProductsList = function(n){
        var url = $location.protocol() + '://' + $location.host() + '/server/api/products/latest/'+n;
        return $http({
            method: 'GET',
            url: url
        }).then(function successCallback(response) {
            // you can edit the response her, and parse it
            return response ;
        }, function errorCallback(response) {

        });
    }
    return factory;
}]);
