I’m trying to figure out a way to keep my angular variables with page refresh / across controllers. My workflow is,
- user logs in via facebook and gets an access token
- users access token will be used with every request
I tried two ways,
1 – Assigning the token to a rootScope
Not working
2 – By using a factory
#app.js
'use strict';
angular.module('recipeapp', [])
.run(['$rootScope', '$injector', 'Authenticate', function($rootScope,$injector, Authenticate){
$injector.get("$http").defaults.transformRequest = function(data, headersGetter) {
$injector.get('$http').defaults.headers.common['auth-token'] = Authenticate.getToken();
}
}]);
#factory
'use strict';
angular.module('recipeapp')
.factory('Authenticate', function(){
var factory = {};
var accessToken = "";
factory.setToken = function(token) {
accessToken = token;
}
factory.getToken = function() {
return accessToken;
}
return factory;
})
#facebook controller
I set the the token with every successful login
Authenticate.setToken(data.app_token);
But the problem is, If I refresh the page, Authenticate.getToken() becomes blank. I’m pretty new to angular and cannot figure out a way to retain my data after a page refresh
any help would be much appreciated
Answer
You can use localStorage. It is really easy to use.
var token = "xxx";
localStorage.setItem("token", token);
localStorage.getItem("token"); //returns "xxx"
