since version 5.20231.* Please use Google's own authentication methods.
Provides a simple way to use Google's GAPI OAuth functionality.
To use, create an instance of the OAuth2 class and add a handler to the userChanged event to monitor the {@link @user} property, which is non-null if a user is currently signed in.
Use the signIn and signOut methods to sign in or out of the Google account.
For example, the code below creates an OAuth2 object and uses it to manage a button used to log users in and out of the application:
import { OAuth2 } from '@mescius/wijmo.cloud'; // create OAuth2 object const API_KEY = 'XXXX'; const CLIENT_ID = 'YYYY.apps.googleusercontent.com'; const SCOPES = [ 'https://www.googleapis.com/auth/userinfo.email' ]; const auth = new OAuth2(API_KEY, CLIENT_ID, SCOPES); // click a button to log in/out let oAuthBtn = document.getElementById('auth_btn'); oAuthBtn.addEventListener('click', () => { if (auth.user) { auth.signOut(); } else { auth.signIn(); } }); // update button caption and accessToken when user changes auth.userChanged.addHandler(s => { let user = s.user; oAuthBtn.textContent = user ? 'Sign Out' : 'Sign In'; gsNWind.accessToken = user ? s.accessToken : null; fsNWind.accessToken = user ? s.accessToken : null; });
