How can I prevent Angular from automatically redirecting to the default page (defined using the otherwise method) even when a valid route is specified?

I've encountered an issue while sending an email with an invitation link. The link provided in the email is

myapp.com/#/invitation/J5QSXr9/token/J6ixelV3
. However, when I click on it, it automatically redirects to my default page myapp.com/#/login, which is not the desired behavior. Interestingly, when I click back on the browser, the correct web page is displayed. Here's the routing configuration I have defined using angular:

var myApp = angular.module('myApp', ["firebase"]).config(

['$routeProvider',
    function($routeProvider){
        $routeProvider.when('/login', {templateUrl:'partials/login.html', controller:'LoginCtrl'});
        $routeProvider.when('/todos', {templateUrl:'partials/todos-list.html', controller:'TodosListCtrl', authRequired:true, pathTo: '/todos'});
        $routeProvider.when('/todos/:todosId', {templateUrl:'partials/todos-detail.html', controller:'TodoCtrl', authRequired:true});
        $routeProvider.when('/invitation/:todosId/token/:tokenNum', {templateUrl:'partials/invitation.html', controller:'InvitationCtrl', authRequired:false});
        $routeProvider.otherwise({redirectTo:'/login'});
    }]
)

// establish authentication
.run(['angularFireAuth', '$rootScope', function(angularFireAuth, $rootScope) {
  var url="https://myapp.firebaseio.com/";
  angularFireAuth.initialize(url, {scope: $rootScope, name: "user", path:"/login"});

}]);

In this setup, I'm utilizing angular's $routeProvider along with Firebase and angularFire for authentication using angularFireAuth. Despite setting authRequired:false for the route

/invitation/:todosId/token/:tokenNum
to allow unrestricted access, it keeps redirecting to /login. It's puzzling that the browser history shows the correct page, leading to a functional display upon clicking back.

Any insights on what might be causing this peculiar behavior?

Answer №1

After facing a similar issue, I found a solution that worked for me. In the angularFire.js file where the new FirebaseSimpleLogin is invoked (around line 440), I observed that self._loggedOut() was being called after page load without a valid login. To address this, I added a condition to only trigger it when a redirect was necessary by including if ($route.current.authRequired). This modification resulted in the following code:

[...]
var client = new FirebaseSimpleLogin(this._ref, function(err, user) {
  self._cb(err, user);
  if (err) {
    $rootScope.$broadcast("angularFireAuth:error", err);
  } else if (user) {
    self._loggedIn(user)
  } else {
    if ($route.current.authRequired)
      self._loggedOut();
  }
});
this._authClient = client;
[...]

I hope this explanation clarifies why this adjustment was necessary...
