javascript - 使用工厂内部路由 Controller

Question

我有这样的工厂:

angular.module('commentsApp')
        .factory("getCommentsFactory", getCommentsFactory);

function getCommentsFactory(scope, $http)
{
    return {
        getComments: getComments
    };

    function getComments()
    {
        return $http.get("/api/comments/" + scope.param)
                .then(getCommentsComplete)
                .catch(getCommentsFailed);

        function getCommentsComplete(data) {
        //GET ALL USER AND COMMENTS TOGETHER
            return data;
        }

        function getCommentsFailed(error) {
            scope.setLoading(false);
            return error;
        }
    }

}

当我尝试从我的 Controller 调用这个工厂时，如下所示:

.controller('CommentsCtrl',function($scope,$http,$routeParams,getCommentsFactory){
              $scope.param = $routeParams.id;
              $scope.comments = [];
              getCommentsFactory.getComments()
                      .then(function(data){
                          console.log(data);
              });
...

我收到错误:

有人知道问题出在哪里吗？

问题是您正在工厂中注入(inject)称为“范围”的东西，但没有可以在那里注入(inject)的范围。

如果您需要来自 Controller 的值，您应该将其作为函数中的参数传递。您无法在工厂中注入(inject) Controller 作用域。
