我想从 app.js 文件中调用控制器方法 [getFacility()]。但是当我使用下面的代码段时，我得到了类似的错误

Error: [$injector:unpr] Unknown provider:

这是我的控制器文件和服务文件

应用程序.js

...
...     
.state('facilityHome.editFacility', 
{
   url: '/editFacility/:facilityId',
   templateUrl: '/views/facility/newFacility.html',
   controller: 
        function($scope, $stateParams, facilityController) {
                facilityController.getFacility($stateParams.facilityId);
         }
}

....
...

设施Controlelr.js

app.controller('facilityController',
['$scope', '$rootScope','$location','$filter', 'facilityService',
    function ($scope, $rootScope,$location,$filter, facilityService){

        /* Assign Object */
        var facilityScope = this;

        /* Initialize DTO Object */
        facilityScope.facilityDTO={
            id:null,
            version:null,
            facilityName:"",
            description:""
        };


        /* Initialize Object Array */
        facilityScope.facilityList = [];


        facilityScope.getFacility=function(id){
            facilityService.fetchFacility(id)
                .then(
                function(successRespond) {
                    $scope.facilityDTO = successRespond;
                },
                function(errResponse){
                    console.error('Error while fetching');
                    console.error(errResponse);
                }
            );

        };

    }
]);

这是我在控制台中得到的。

要将控制器注入另一个控制器，请使用该$controller服务。

.state('facilityHome.editFacility', 
{
   url: '/editFacility/:facilityId',
   templateUrl: '/views/facility/newFacility.html',
   controller: 
       function($scope, $stateParams, $controller) {
           var facCtrl = $controller("facilityController", {'$scope': $scope});
           facCtrl.getFacility($stateParams.facilityId);
       }
}

因为facilityController操纵$scope，$scope需要作为局部注射。

有关更多信息，请参阅AngularJS $controller 服务 API 参考。

您不能在另一个控制器中注入控制器。您需要工厂/服务。

查看一些文档：https ://docs.angularjs.org/guide/services
