angularjs - 无法使用角度工厂交叉路线

Question

我正在尝试创建一个工厂并在每个控制器中交叉使用它，但显然我做错了什么......

应用程序：

var app = angular.module('sam', ['ngRoute', 'ngGrid', 'ui.bootstrap']);

工厂

app.factory("User",function(){
        return {};
    });

路线

// configure our routes
app.config(function($routeProvider) {
        $routeProvider

            // route for the main page which will direct to the buildings page
            .when('/', {
                templateUrl : 'web/pages/buildings.html',
                controller  : 'mainController',
                controllerAs : 'buildings'
            })

    }); 

控制器

app.controller('mainController', ['$filter', '$http','$log', function($filter, $http, $log, User){
        $log.log('hello!!!!!', User);
}]);

这打印：hello!!!!! undefined

Answer 1

您的控制器中缺少“用户”。

app.controller('mainController', ['$filter', '$http','$log', **'User',** function($filter, $http, $log, User){
        $log.log('hello!!!!!', User);
}]);

Answer 2

您忘记将User其作为注入数组的一部分包含在内

controller('mainController', ['$filter', '$http','$log', function($filter, $http, $log, User){

应该：

controller('mainController', ['$filter', '$http','$log','User', function($filter, $http, $log, User){

Answer 3

app.factory("User",function(){
    return {
           show:function(){
                alert('Factory called')
           }
};
});




app.controller('mainController', ['$filter', '$http','$log','User', function($filter, $http, $log, User){

  //that is the way you can call your factory
  // you can call this factory function in any controller by injecting it.

      User.show(); //will popup alert window.

}]);
