angularjs – Angular UI路由器无法解析注入的参数

因此,请考虑我的angularUI路由设置中的以下片段.我正在导航到路线/类别/管理/ 4 /详细信息(例如).我希望在相关控制器加载之前解析’category’,实际上我可以在resolve函数中放置一个断点,该断点返回类别服务中的类别,并看到该类别已被返回.现在在控制器本身内放置另一个断点,我可以看到“类别”总是未定义的.它不是由UI路由器注入的.

有谁能看到这个问题？它可能在我提供的代码之外的某个地方,但由于我在运行代码时没有错误,因此无法确定问题的根源所在.典型的js无声失败！

.state('category.manage',{
            url: '/manage',templateUrl: '/main/category/tree',controller: 'CategoryCtrl'
        })
        .state('category.manage.view',{
            abstract: true,url: '/{categoryId:[0-9]*}',resolve: {
                category: ['CategoryService','$stateParams',function (CategoryService,$stateParams) {
                    return CategoryService.getCategory($stateParams.categoryId).then(returnData); //this line runs before the controller is instantiated
                }]
            },views: {
                'category-content': {
                    templateUrl: '/main/category/ribbon',controller: ['$scope','category',function ($scope,category) {
                        $scope.category = category; //category is always undefined,i.e.,UI router is not injecting it
                    }]
                }
            },})
