                    return _environment;
                }

                for(var environment in _environments){
                    if(typeof _environments[environment].host && _environments[environment].host == host){
                        _environment = environment;
                        return _environment;
                    }
                }

                return null;
            },
            get: function(property){
                return _environments[this.getEnvironment()].config[property];
            }
        }

    });

})();

使用此服务，但它说在配置时间env.get（'apiroot'）时config是未定义的

请多多指教我在哪里错了

///我想为购物，本地和生产设置环境，我尝试使用此自定义服务，但遇到错误，请指导

由于主机名和api不正确，请对它们使用相同的

(function(){
    'use strict';

    angular.module('app').service('env', function env() {

        var _environments = {
            local: {
                host: 'localhost:9000',
                config: {
                    apiroot: 'http://localhost:9000'
                }
            },
            dev: {
                host: 'dev.com',
                config: {
                    apiroot: 'http://localhost:3000'
                }
            },
            test: {

                return null;

            }
        }

    });

})();
