AngularJS Resolve a route based on a service promise -

-

i using ngroute , and trying routes resolve based on result of function in service have defined

my service follows:

app.factory('authservice', function ($q,$location,$http) { var isloggedin = false;      return {         hasloginsession: function(){             var defer = $q.defer();             if(isloggedin) {                 //user has valid session previous getsession.json request                 defer.resolve(isloggedin);             } else {                   return $http.get('/session/getsession.json').success(function(data, status, headers, config) {                     isloggedin = data.success;                     if(isloggedin) {                         defer.resolve(isloggedin);                     }                     else {                         defer.reject("ex_login_session_is_unknown");                     }                 }).                 error(function(data, status, headers, config) {                     isloggedin=false;                     defer.reject("ex_login_session_is_unknown");                 });              }             return defer.promise;          }     };  });

so can see have simple session check function sets property based on result of http request.

i have routing setup so, resolve on route path testing @ moment:

var app = angular.module('pinpointersapp', ['ngroute']);  app.config(   function($routeprovider,$httpprovider) {       //$httpprovider.interceptors.push(interceptor);       $routeprovider.      when('/login', {         templateurl: 'login.html',         controller: 'logincontroller'       }).       when('/map', {         templateurl: 'partials/map.html',         controller: 'mapcontroller'       }).       when('/locations', {         templateurl: 'partials/locations.html',         controller: 'locationscontroller'        }).      when('/', {         templateurl: 'partials/locations.html',         controller: 'locationscontroller',         resolve: {             checksession: function ($q,authservice) {                 //var defer = $q.defer();                 //defer.reject("ex_login_session_is_unknown");                 //return defer.promise;                 return authservice.hasloginsession();              }          }       });  });  app.run(['$rootscope', 'authservice', function ($rootscope, authservice) {    $rootscope.$on("$routechangeerror", function (event, current, previous, error) {        console.log(error);        //perform other stuff here, e.g. redirect login view    });  }]);

the server side request being made, , seeing pause in view loading until response received. in test returning fail case , reject state of promise in order cause $routechangeerror fired, never , view continues load.

if use commented out lines of test code in resolve block instead of service routine call, so

resolve: {             checksession: function ($q,authservice) {                 var defer = $q.defer();                 defer.reject("ex_login_session_is_unknown");                 return defer.promise;                 //return authservice.hasloginsession();              }          }

then routechangeerror event fired, missing in order use result of service routine call?

ok, figured out did wrong, in service had 1 many return statements, needed remove return keyword before opening $http request , works required.
