ui-router在解析父状态之前触发子状态

Question

我试图在Angular ui-router的父状态中执行一些初始化代码.初始化代码orderService.getStoreInfo()返回一个promise.只有当这个承诺得到解决时,我才能触发子状态.但是,我注意到,即使在父母的承诺解决之前,孩子的状态也会被触发.我究竟做错了什么？这是'我的代码:

function configure($stateProvider, $urlRouterProvider) {

    $urlRouterProvider.otherwise('/');

    $stateProvider
        .state('home', {
            abstract: true,
            template: '<ui-view/>',
            resolve: {
                storeInfo: /* @ngInject */ function(orderService) {
                    console.log('home: resolve - orderService.getStoreInfo()');
                    return orderService.getStoreInfo();
                }
            }
        })

        .state('home.orders', {
            url: '^/',
            template: '<my-order-list data-orders="vm.orders"></my-order-list>',
            resolve: {
                orders: /* @ngInject */ function (orderService) {
                    console.log('home.orders: resolve - orderService.getOrders()');
                    return orderService.getOrders();
                }
            },
            controller: ['orders', function (orders) {
                this.orders = orders;
            }],
            controllerAs: 'vm',
        });
}

控制台日志如下:

home: resolve - orderService.getStoreInfo()
home.orders: resolve - orderService.getOrders()
... messages from orderService.getStoreInfo() ...

这清楚地表明,即使在父州解决之前,子州仍在解雇.

Answer 1

答案就在这里:resolve如果你想在实例化孩子之前等待答案得到解决,那么必须将键注入子状态.所以只需明确注入storeInfo子状态的解析函数.
