我在下面提供了我的代码。基本上,当我加载我的视图时,我使用resolve来获取一些数据。在我的服务中,如果我的承诺被拒绝 - 在出错时 - 解决方案被无限调用。我应该有更好的方式来执行此操作吗?
(function () {
function AppService($q, $http, $log, $timeout, pageOptionsModel) {
return {
getPageOptions: function () {
var deferred = $q.defer();
var pageOptions = pageOptionsModel.getPageOptions();
if (pageOptions === null) {
$http.get("api/HomeApi/GetPageOptions")
.success(function (response) {
deferred.resolve(response);
$log.info("Successfully retriedved page options from service.");
})
.error(function (response) {
deferred.reject("Error");
$log.error("Errored while retrieving page options from service.");
});
}
else {
deferred.resolve(pageOptions);
}
return deferred.promise;
}
}
};
function AppConfig($stateProvider, $urlRouterProvider, $locationProvider) {
$urlRouterProvider.otherwise("line");
// Now set up the states
$stateProvider
.state('line', {
url: "/line",
templateUrl: "app/line/lineTemplate.html",
controller: "lineController",
controllerAs: "line",
resolve: {
pageOptions: function (appService) {
return appService.getPageOptions();
}
}
});
$locationProvider.html5Mode({
enabled: true,
requireBase: false
});
};
angular.module("app", ["ui.router", "ui.bootstrap", "app.line", "app.modal"])
.config(AppConfig)
.factory("appService", AppService);
})();
这是我的线路控制器,如果我的承诺被拒绝,它永远不会初始化。
(function () {
function LineController($scope, pageOptions) {
var self = this;
// INITIALIZE
self.pageOptions = pageOptions;
};
angular.module("app.line")
.controller("lineController", LineController);
})();
