HttpRequestInterceptor display multiples times the same error


I added a HttpRequestInterceptor insie my AngularJS app to display a toastr every time a request fails.

angular.module('spwApp.factories')
    .factory('httpRequestInterceptor', ['$q', '$injector', '$cookies', '$rootScope', function($q, $injector, $cookies, $rootScope) {
        return {
            'request': function($config) {
                var token = $cookies.get('token');
                $config.headers['Authorization'] = 'Bearer ' + token;
                return $config;
            },
            'responseError': function(rejection) {
                var toastr = $injector.get('toastr');
                var $state = $injector.get('$state');
                toastr.options = {
                    "closeButton" : true,
                    "preventDuplicates" : true,
                    "timeOut": "50000",
                    "extendedTimeOut" : "50000"
                };
                toastr.remove();
                switch (rejection.status) {
                    case 401:
                        if ($state.current.name != 'login') {
                            $state.go('login');
                            toastr.info('Re-enter username/password', 'Invalid sessions', toastr.options);
                        }
                        break;
                    case 403:
                        toastr.error('You do not have the rights', 'Forbidden', toastr.options)
                        $state.go('home');
                        break;
                    case 404:
                        toastr.error('Cannot found', '??', toastr.options);
                        $state.go('home');
                        break;
                    case 500:
                        toastr.error('Unexpected error', 'Hum...', toastr.options);
                        $state.go('home');
                        break;
                    case -1:
                        toastr.error('Connection to server not possible', 'Ouch...', toastr.options);
                        $state.go('home');
                        break;
                    default:
                        toastr.error('That is not supposed to land here', 'Oops...', toastr.options);
                        $state.go('home');
                        break;
                }
                return $q.reject(rejection);
            }
        };
    }]);

On certain page, I have to resolve multiple data from my server

.state('stateA', {
    url: '/urlToStateA',
    views: {
        'content@stateA': {
            templateUrl: 'app/stateA.html',
            controller: 'controllerA',
            controllerAs: 'vm',
            resolve: {
                dataA: ['myService', function(myService) {
                    return myService.getDataA();
                }],
                dataB: ['myService', function(myService) {
                    return myService.getDataB();
                }],
                dataC: ['myService', function(myService) {
                    return myService.getDataC();
                }]
            }
        }
    }
})

Thus when my server is turned off, each request will get a rejection.status == -1 and then display the toastr Connection to server not possible

The problem is that the line toastr.remove(); does not work. It is supposed to remove all the toastr but does nothing.

How can I remove the toastr before adding a new one ? Can I replace the non-working toastr.remove() with some pure javascript to manually select and remove the toastr ?


Solution

  • You have to make some configuration changes to prevent more toastr's opening simultaneously.

    The toastr configurations can be changed in config function of angular.

    myApp.config(Config);
    
      function Config($httpProvider,toastrConfig) {
    
        $httpProvider.interceptors.push('interceptorService');
    
        angular.extend(toastrConfig, {
           autoDismiss: false,
           containerId: 'toast-container',
           maxOpened: 0,    
           newestOnTop: true,
           positionClass: 'toast-top-center',
           preventDuplicates: false,
           preventOpenDuplicates: true,
           target: 'body'
        });
    
      }  
    

    preventOpenDuplicates: true this line will prevent the same message from displaying multiple times.
