Navigating with Angular - sending users to an external webpage?

Question

Navigating with Angular - sending users to an external webpage?

When working with AngularJS routes, there is the option to use an otherwise route as a replacement for a 404 error:

$routeProvider
.when(...)
.otherwise({
    redirectTo: 'my/path'
});

Is it possible to configure the otherwise route to redirect to a page that is outside of the application? I attempted to accomplish this by using:

$routeProvider
.when(...)
.otherwise({
    redirectTo: 'http://example.com'
});

However, this simply tried to redirect to that path within my app, which does not exist. The workaround that I am aware of involves manually handling redirection in a $scope.$on('$routeChangeStart') event listener in a top-level controller, but this approach results in code duplication and is considered unsightly. Is there a more efficient solution available?

From my understanding, achieving this might be challenging since the routeProvider is designed to handle internal routes exclusively.

However, a workaround could involve:

$routeProvider
.when(...)
.otherwise({
    controller: "404Controller",
    template: "<div></div>"
});

After that, you can simply use

window.location.href = 'http://yourExternalSite.com/404.html'

within the controller.

This solution proved to be effective for me personally:

$routeProvider
.when('/my-path', {
    ...usual configurations...
}).
.otherwise({
        redirectTo: function(obj, requestedPath) {
            window.location.href = appConfig.url404;
        }
});

Have you checked out this thread on how to disable deep linking for specific URLs in Angular.js? It might be helpful.

Here is a solution that you can use:

target="_self"

<a href="link" target="_self" >link</a>

Instead of solely relying on window.location.href in a new controller, I would caution against it as it can cause issues with ngRoute setting the history incorrectly, leading to constant redirection to a 404 page when users click back. I attempted this method and encountered failure.

For an alternative solution, I recommend checking out my response to a similar query on SO here:

I implemented that approach to address your situation. Utilizing MainCtrl outside of ng-view may not be a bad idea, especially if it is only declared once unless there are nested ng-view layers. There should be no code duplication concern, and you have the option to place MainCtrl in a separate module for better organization:

.config(['$routeProvider', function($routeProvider) {
  $routeProvider
  .when(..) 
  .otherwise({redirectTo: 'http://yourExternalSite.com/404.html'}); 
}])
.controller('MainCtrl',[ // <- Use this controller outside of the ng-view!
  '$rootScope','$window',
  function($rootScope,$window){
    $rootScope.$on("$routeChangeStart", function (event, next, current) {
      // next.$$route <-not set when routed through 'otherwise' since none $route were matched
      if (next && !next.$$route) {
        event.preventDefault(); // Stops the ngRoute to proceed with all the history state logic
        // We have to do it async so that the route callback 
        // can be cleanly completed first, so $timeout works too
        $rootScope.$evalAsync(function() {
          // next.redirectTo would equal be 'http://yourExternalSite.com/404.html'
          $window.location.href = next.redirectTo;
        });
      }
    });
  }
]);
