为什么我的控制器找不到我的服务？

Question

当运行此代码时，我一直收到 "Error: $injector:unpr Unknown Provider"。我已经查看了很多与此问题类似的其他答案，但看不出错误在哪里。

此外，我使用 "myService()" 调用此服务是否正确？

我是 Angular 的新手，所以如果有任何帮助或建议，我们将不胜感激。提前致谢。

我的服务

angular.module('APP')

  .service('myService', ['$scope' function($scope) {

    $scope.search = {};

    $scope.resetFilters = function () {
        // needs to be a function or it won't trigger a $watch
        $scope.search = {};
    };

    // pagination controls
    $scope.currentPage = 1;
    $scope.totalItems = $scope.videos.length;
    $scope.entryLimit = 5; // videos per page
    $scope.noOfPages = Math.ceil($scope.totalItems / $scope.entryLimit);

    // $watch search to update pagination
    $scope.$watch('search', function (newVal, oldVal) {
        $scope.filtered = filterFilter($scope.videos, newVal);
        $scope.totalItems = $scope.filtered.length;
        $scope.noOfPages = Math.ceil($scope.totalItems / $scope.entryLimit);
        $scope.currentPage = 1;
    }, true);

}]);

我的控制器

angular.module('APP')

  .filter('startFrom', function () {
      return function (input, start) {
          if (input) {
              start = +start;
              return input.slice(start);
          }
          return [];
      };
  })

  .controller('dbCtrl', ['$scope', '$http', 'filterFilter', 'myService', function ($scope, $http, filterFilter, myService) {

    $http.get("js/science.php")
      .success(function(data){
          $scope.videos = data;

          myService();
      })
      .error(function() {
          $scope.data = "error in fetching data";
    });

}]);

抱歉，我应该提到，我有一个主应用程序文件，我在其中使用 angular.module('APP', []); 声明了我的应用程序依赖项至于无法将 $scope 注入服务，我真的只是想获取分页代码并使其可重用。关于如何实现这一目标的任何想法？顺便感谢您的快速回复。

这是原始控制器，其中包含我想使其可重复使用的分页代码。

angular.module('APP')

  .filter('startFrom', function () {
      return function (input, start) {
          if (input) {
              start = +start;
              return input.slice(start);
          }
          return [];
      };
  })

  .controller('dbCtrl', ['$scope', '$http', 'filterFilter', function ($scope, $http, filterFilter) {

    // Link to PHP for mySQL content
    $http.get("js/science.php")
      .success(function(data){
        $scope.videos = data; // Array named 'data'

        // FROM HERE
        //=====================
        $scope.search = {};

        $scope.resetFilters = function () {
            // needs to be a function or it won't trigger a $watch
            $scope.search = {};
        };

        // pagination controls
        $scope.currentPage = 1;
        $scope.totalItems = $scope.videos.length;
        $scope.entryLimit = 5; // videos per page
        $scope.noOfPages = Math.ceil($scope.totalItems / $scope.entryLimit);

        // $watch search to update pagination
        $scope.$watch('search', function (newVal, oldVal) {
            $scope.filtered = filterFilter($scope.videos, newVal);
            $scope.totalItems = $scope.filtered.length;
            $scope.noOfPages = Math.ceil($scope.totalItems / $scope.entryLimit);
            $scope.currentPage = 1;
        }, true);
        // TO HERE REUSABLE
        //=====================

        })

      .error(function() {
          $scope.data = "error in fetching data";
    });

}]);

Why can't my controller find my service?
