使用Ionic AngularJS$http PUT、POST或DELETE请求时出现选项错误

我知道这已经被问了一次又一次，但我似乎无法解决我的问题，无论我尝试什么解决方案

我正在尝试在Ionic中使用AngularJS创建一个新用户。我在本地主机上安装了一个小型REST服务器，并对应用程序进行了测试。因此，它们位于同一服务器上，但位于不同的文件夹中。尽管如此，出于某种原因，我仍然需要申请CORS

在服务中使用AngularJS中的$http方法，我可以执行GET请求。但是，当我尝试PUT、POST或DELETE请求时，控制台中会出现选项错误。下面是我的设置

API index.php文件

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept');

OPTIONS http://localhost/z-projects/git-motostatsfree/MotoStats/MotoStatsAPI/credentials/add_user 
(index):1 XMLHttpRequest cannot load http://localhost/z-projects/git-motostatsfree/MotoStats/MotoStatsAPI/credentials/add_user. Invalid HTTP status code 404

我的用户SVC

app.factory('UsersSvc', function($http, $location){

    return {

        /**
         * Adds a user to the database
         *
         * @param user
         * @returns {*}
         */
        addUser: function(user){

            // User Format...
            // user.user_email, user.user_password

            return $http.post($location.apiUrl + '/credentials/add_user',
                {user: user}).

                success(function(data){return data});

        }

    };

});

Rest服务器API方法（我使用CodeIgniter和Phil Sturgeon的Rest服务器）

Chrome控制台中的错误

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept');

OPTIONS http://localhost/z-projects/git-motostatsfree/MotoStats/MotoStatsAPI/credentials/add_user

任何朝着正确方向的解决方案或推动都将是巨大的帮助。我已经为此工作了4个小时，但仍然无法解决问题。

下面链接中的答案很快解决了我的问题，但我仍然不知道为什么会发生这种情况。。。你好将所有请求标头添加到访问控制允许标头选项中
