将API方法构建为角度服务

几天前，当我开始使用AngularJS时，我发现了很多有用的东西，我意识到在你的网络应用程序中使用它比从头开始构建所有东西更容易（有时这是必要的，但在大多数情况下不是）或使用大量可能会打乱应用程序加载时间的库。

因此，我为一个网上商店提供了一个php API包装器，里面有很多方法（我试图模仿REST，但API只提供POST和GET），我开始为它构建一个JS脚本，可以在不了解php或不必接触任何php代码的情况下调用这些方法。

使用AngularJS，我想到了这个：

var Application = Application || {};
;(function($, window, document, undefined) {
"use strict";
var Envato = {};
Application.Envato = angular.module("Envato", []);
Application.Envato.constant("API", {
    Path : {
        Private : "api/envato/private/",
        Public : "api/envato/public/"
    }
});
})(jQuery, window, document);

上面是我的模块，放在modules文件夹中。下一个，将是围绕模块的工厂构建（与上述模块放在同一文件夹中）：

var Application = Application || {};
;(function($, window, document, undefined) {
"use strict";
Application.Envato.factory("APIXHRService", function($http, $timeout, $q) {
    return function(method, url, data) {
        var deferred = $q.defer(),
            headers = {
                "Content-Type" : "Application/JSON"
            };
        $http({ method : method, url : url, data : data, headers : headers }).success(function(_data) {
            deferred.resolve(_data);
            deferred = $q.defer();
        }).error(function(_data) {
            deferred.resolve(_data || "Request [ Failed ]");
            deferred = $q.defer();
        });
        return deferred.promise;
    };
});
Application.Envato.factory("Envato", function(APIXHRService, API) {
    return {
        API : {
            Private : {
                User : {
                    Account : function(user){
                        return APIXHRService("POST", API.Path.Private + "get-account-information.php", { user : user });
                    },
                    Statement : function(user) {
                        return APIXHRService("POST", API.Path.Private + "get-statement.php", { user : user });
                    },
                    Sales : function(user) {
                        return APIXHRService("POST", API.Path.Private + "get-recent-sales.php", { user : user });
                    },
                    Transactions : function(user) {
                        return APIXHRService("POST", API.Path.Private + "get-earnings-and-sales-by-month.php", { user : user });
                    },
                    Vitals : function(user) {
                        return APIXHRService("POST", API.Path.Private + "get-user-vitals.php", { user : user });
                    }
                },
                Purchases : {
                    Download : function(user, token) {

            Public : {

                        return APIXHRService("GET", API.Path.Public + "get-api-releases.php");
                    }
                },
                Blog : {
                    Posts : function(marketplaces) {
                        return APIXHRService("POST", API.Path.Public + "get-blog-posts.php", { marketplaces : marketplaces });
                    },

                        },
                        Random : function(marketplaces) {
                            return APIXHRService("POST", API.Path.Public + "get-random-new-items.php", { marketplaces : marketplaces });

                        }
                    },
                    Popular : function(marketplaces) {
                        return APIXHRService("POST", API.Path.Public + "get-popular-items.php", { marketplaces : marketplaces });
                    },
                    Price : function(items) {
                        return APIXHRService("POST", API.Path.Public + "get-item-price.php", { items : items });
                    }
                },
                Users : {
                    Information : function(users) {
                        return APIXHRService("POST", API.Path.Public + "get-user-information.php", { users : users });
                    },
                    Items : {
                        Count : function(users) {
                            return APIXHRService("POST", API.Path.Public + "get-user-items-by-site.php", { users : users });
                        }
                    },
                    Total : function() {
                        return APIXHRService("GET", API.Path.Public + "get-total-users-count.php");
                    },
                },
                Search : function(expression, marketplace, categories) {
                    return APIXHRService("POST", API.Path.Public + "get-search-results.php", { expression : expression, marketplace : ( marketplace === undefined ? "" : marketplace ), categories : ( categories === undefined ? "" : categories ) });
                }
            }
        }
    };
});
})(jQuery, window, document);

最后，如果需要的话，我有一个控制器，可以检查这些方法是否正常工作：

var Application = Application || {};
;(function($, window, document, undefined) {
"use strict";
Application.controller("EnvatoAPIController", ["$scope", "_debounce", "Envato", function($scope, _debounce, Envato) {
    $scope.getData = _debounce(function($event) {
        $event.preventDefault();
        return Envato.API.Private.Purchases.Download("chaoscod3r", "52dfdscb1-dada-4ff8-bfcb-d3fdsbn55mda").then(function(data) {
            $scope.data = JSON.stringify(data, undefined, 4);
        });
    }, 250, false);
}]);
})(jQuery, window, document);

我之所以发布这篇文章，是因为我想了解如何改进我的代码，因为在我看来，这里面有点太多了。也许Angular有更好的方法？我还没有机会通过所有AngularJS API文档，所以我想这里一定有很多开发人员在使用Angular，可以给我一些提示：）

编辑：问题是如何折射Envato工厂？哪种方式最好？
