The Challenge of Managing Storage with Angular RestangularInterceptor

The Challenge of Managing Storage with Angular RestangularInterceptor

Currently, I am utilizing a RestangularProvider to implement an $http interceptor for injecting an authentication header into all restangular requests. However, I have encountered an issue where I cannot inject services into app.config(), preventing me from accessing the angular local storage necessary for storing the token obtained from the login server.

angular.module('app').config(function(RestangularProvider, localStorageService) {
    RestangularProvider.setBaseUrl('/api/');

    RestangularProvider.setFullRequestInterceptor(function(element, operation, route, url, headers, params, httpConfig) {
       var authData = localStorageService.get('authorizationData');//ERROR:localStorageService doesn't exist
        };
});

The "authorizationData" serves as my locally stored authentication token. It's clear that both the Restangular provider and local storage are essential for my application. If anyone has any suggestions or workarounds, I would greatly appreciate it. Thank you!

Answer №1

One limitation is that you cannot inject a service into angular configuration during the .config phase. Only providers/constants are accessible at this point, as they are intended for configurable services.

To work around this issue, you can transform localStorageService into a provider instead of using service/factory, and then inject it into the config block as localStorageProvider.

Another method to achieve this is by using $injector to retrieve the instance of localStorageService. To do this, you will need to inject $injector and then create a variable like:

localStorageService = $injector.get('localStorageService');

This allows you to obtain an instance of localStorageService dynamically.
