问题
I'm trying to create an SPA where you have to be logged in to access almost everything. So naturally, the default screen you see is the login screen. However, after a user has logged in, no matter what the ui-sref is, ui-router redirects to the login page (even when the user is authenticated). Here is my ui-router code:
(function () {
'use strict';
angular
.module('app', ['ui.router', 'satellizer'])
.config(function ($stateProvider, $urlRouterProvider, $authProvider, $httpProvider, $provide) {
$httpProvider.interceptors.push(['$q', '$injector', function($q, $injector){
return {
responseError: function (rejection) {
var $state = $injector.get('$state');
var rejectionReasons = ['token_not_provided', 'token_expired', 'token_absent', 'token_invalid'];
angular.forEach(rejectionReasons, function (value, key) {
if (rejection.data.error === value) {
localStorage.removeItem('user');
$state.go('auth');
}
});
return $q.reject(rejection);
},
response: function(response) {
var authorization = response.headers('authorization');
if(authorization !== null) {
authorization = authorization.substr(7).trim();
//console.log(authorization);
var $auth = $injector.get('$auth');
$auth.setToken(authorization);
}
return response;
}
}
}]);
$authProvider.loginUrl = 'mingdaograder/api/authenticate';
$stateProvider
.state('users', {
url: '/users',
templateUrl: 'views/userView.html',
controller: 'UserController as user'
})
.state('subjects', {
url: '/users/:user_id/subjects',
templateUrl: 'views/subjectsView.html',
controller: 'SubjectsCtrl as subjectsCtrl'
})
.state('subject', {
url: '/users/:user_id/subjects/:subject_id',
templateUrl: 'views/subjectView.html',
controller: 'SubjectCtrl as subjectCtrl'
})
.state('auth', {
url: '/auth',
templateUrl: 'views/authView.html',
controller: 'AuthController as auth'
});
//.state('otherwise', {
// url: '*path',
// templateUrl: 'views/authView.html',
// controller: 'AuthController as auth'
//});
//$urlRouterProvider.otherwise('/auth');
$urlRouterProvider.otherwise(function($injector, $location) {
console.log("Could not find " + $location);
$location.path('/auth');
});
})
.run(function ($rootScope, $state, $log) {
$rootScope.$on('$stateChangeStart', function (event, toState) {
console.log(toState.name);
var user = JSON.parse(localStorage.getItem('user'));
if (user) {
$rootScope.authenticated = true;
$rootScope.currentUser = user;
}
}
);
}
);
})();Anytime I try to use $state.go(any state name here) or even type the address into the address bar, I am always redirected to the auth state. On the console the message is "Could not find http://localhost/#/" for every single route. I can type in http://localhost/#/users/5/subjects and I get the same message.
Here is one of my controllers doing a redirect:
(function () {
'use strict';
angular
.module('app')
.controller('AuthController', AuthController);
function AuthController($auth, $state, $http, $rootScope, $log) {
var vm = this;
vm.loginError = false;
vm.loginErrorText;
vm.login = function () {
var credentials = {
username: vm.username,
password: vm.password
};
$auth.login(credentials).then(function () {
return $http.get('api/authenticate/user');
}, function (error) {
vm.loginError = true;
vm.loginErrorText = error.data.error;
}).then(function (response) {
var user = JSON.stringify(response.data.user);
localStorage.setItem('user', user);
$rootScope.authenticated = true;
$rootScope.currentUser = response.data.user;
//$log.info('From AuthCtrl: ' + $rootScope.currentUser.id);
$state.go('subjects', {user_id:$rootScope.currentUser.id});
});
}
}
})();Any ideas what I'm doing wrong? Thanks a lot for your time.
Update: Ok, I haven't found a way to fix it but I think I may have found a possible cause. It seems to only happen for the routes with parameters. For example, if I go to the users state, whose path is /users, there is no redirect. However, if I go to the subjects state, whose path is /users/:user_id/subjects, it does redirect. It's like the Url matching service can't recognize that /users/5/subjects matches /users/:user_id/subjects, so redirects. Any ideas how to work around this?
回答1:
I found I didn't have a '/' at the beginning of my initial state url. Every time I navigated to the state, the missing '/' seemed to push it into the stateProvider.otherwise.
state1: 'opportunity'
state1Url : '/opportunity/' <== added initial forward slash to make it work.
state2: 'opportunity.create'
state2Url : 'create/'

The first path to be recognised will be the selected as the current location. This means that the order of your route definitions is crucially important. In your case you only have a single catch-all otherwise route definition and since all routes match this then all routes are directed to your login page ignoring any other route definitions you may have, including all your stateProvider state definitions.
One way to fix this is to remove the urlRouterProvider route definition altogether and instead use the *path syntax provided by ui-router to create an alternative otherwise state (which must be defined last for the same reasons given above).
Therefore your code might look something like this:
$stateProvider
.state('auth', {
url: '/auth',
templateUrl: 'views/authView.html',
controller: 'AuthController as auth'
})
.state('users', {
url: '/users',
templateUrl: 'views/userView.html',
controller: 'UserController as user'
})
.state('subjects', {
url: '/users/:user_id/subjects',
templateUrl: 'views/subjectsView.html',
controller: 'SubjectsCtrl as subjectsCtrl'
})
.state('subject', {
url: '/users/:user_id/subjects/:subject_id',
templateUrl: 'views/subjectView.html',
controller: 'SubjectCtrl as subjectCtrl'
})
.state("otherwise", {
url: "*path",
templateUrl: 'views/authView.html',
controller: 'AuthController as auth'
});
