I use this api to provide google login function for my electron app
https://github.com/googleapis/google-auth-library-nodejs
My access token expires after 3600 seconds
I don’t want my users to log in again after 3600 seconds
How can I make the token refresh automatically?
I try to use the document example code on the my app
But it doesn't seem to work
How can I get a new access_token
I try the code below to get a new access_token
But nothing happens
const { app, BrowserWindow, screen } = require('electron');
const fs = require('fs');
const { google } = require('googleapis'); // auth node js
googleOAuth2Login();
function googleOAuth2Login() {
const SCOPES = ['https://www.googleapis.com/auth/drive'];
const TOKEN_PATH = 'token.json';
fs.readFile('credentials.json', (err, content) => {
if (err) return console.log('Error loading client secret file:', err);
authorize(JSON.parse(content), showAccessToken);
});
function authorize(credentials, callback) {
const { client_secret, client_id, redirect_uris } = credentials.installed;
const oAuth2Client = new google.auth.OAuth2(
client_id,
client_secret,
redirect_uris[0]
);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, (err, content) => {
if (err) return getAccessToken(oAuth2Client, callback);
oAuth2Client.setCredentials(JSON.parse(content));
callback(JSON.parse(content))
oAuth2Client.on('tokens', (tokens) => {
//this handle not work
if (tokens.refresh_token) {
// store the refresh_token in my database!
console.log(tokens.refresh_token);
}
console.log(tokens.access_token);
});
});
}
