I have discovered some unusual occurrences in my coding. Specifically, I have an AuthService that handles authentication requirements for my applications, including the authentication token.
@IonicPage()
@Component({
selector: 'page-login',
templateUrl: 'login.html',
})
export class LoginPage {
constructor(public navCtrl: NavController, public navParams: NavParams, public modalCtrl:ModalController,public auth: AuthService) {
}
ionViewDidLoad() {
console.log(this.auth)
console.log(this.auth.loggedIn)
if(this.auth.loggedIn){
console.log(this.auth);
this.navCtrl.push("TabsPage");
}
}
}
When I execute
console.log(this.auth)
it returns authentication. However, when I run
console.log(this.auth.loggedIn)
it returns null. This is perplexing to me.
This is my auth.service.ts:
import { Injectable, NgZone, Component } from '@angular/core';
import { Storage } from '@ionic/storage';
// Import AUTH_CONFIG, Auth0Cordova, and auth0.js
import { AUTH_CONFIG } from './auth.config';
import Auth0Cordova from '@auth0/cordova';
import * as auth0 from 'auth0-js';
@Injectable()
export class AuthService {
Auth0 = new auth0.WebAuth(AUTH_CONFIG);
Client = new Auth0Cordova(AUTH_CONFIG);
accessToken: string;
user: any;
loggedIn: boolean;
loading = true;
constructor(
public zone: NgZone,
private storage: Storage
) {
this.storage.get('profile').then(user => this.user = user);
this.storage.get('access_token').then(token => this.accessToken = token);
this.storage.get('expires_at').then(exp => {
this.loggedIn = Date.now() < JSON.parse(exp);
this.loading = false;
});
}
login() {
this.loading = true;
const options = {
scope: 'openid profile offline_access'
};
// Authorize login request with Auth0: open login page and get auth results
this.Client.authorize(options, (err, authResult) => {
if (err) {
throw err;
}
// Set access token
this.storage.set('access_token', authResult.accessToken);
this.accessToken = authResult.accessToken;
// Set access token expiration
const expiresAt = JSON.stringify((authResult.expiresIn * 1000) + new Date().getTime());
this.storage.set('expires_at', expiresAt);
// Set logged in
this.loading = false;
this.loggedIn = true;
// Fetch user's profile info
this.Auth0.client.userInfo(this.accessToken, (err, profile) => {
if (err) {
throw err;
}
this.storage.set('profile', profile).then(val =>
this.zone.run(() => this.user = profile)
);
});
});
}
logout() {
this.storage.remove('profile');
this.storage.remove('access_token');
this.storage.remove('expires_at');
this.accessToken = null;
this.user = null;
this.loggedIn = false;
}
isLoggedIn() :boolean{
return this.loggedIn;
}
}
As I use Ionic3 and Auth0 authentication, I initially suspected that the issue was due to not using a public identifier on my property. Even after making changes by adding a public keyword or creating a getter method, the problem persists.
