how to get oauth token?

[yadavsingh]

URL: https://developers.google.com/calendar/quickstart/php
This is generating only credentials.json, not token.json. How to get token.json?

[jl0nd0n0]

Run sample according to the instructions

In this line generate file token.json:

file_put_contents($tokenPath, json_encode($client->getAccessToken()));

It's already set in quickstart.php, juste before the end :

<?php
require __DIR__ . '/vendor/autoload.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object

function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Google Calendar API PHP Quickstart');
    $client->setScopes(Google_Service_Calendar::CALENDAR);
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    $client->setPrompt('select_account consent');

    // Load previously authorized token from a file, if it exists.
    // The file token.json stores the user's access and refresh tokens, and is
    // created automatically when the authorization flow completes for the first

    $tokenPath = 'token.json';
    if (file_exists($tokenPath)) {
        $accessToken = json_decode(file_get_contents($tokenPath), true);
        $client->setAccessToken($accessToken);
    }

    // If there is no previous token or it's expired.
    if ($client->isAccessTokenExpired()) {
        // Refresh the token if possible, else fetch a new one.
        if ($client->getRefreshToken()) {

        } else {
            // Request authorization from the user.
            $authUrl = $client->createAuthUrl();

            $authCode = trim(fgets(STDIN));

            // Exchange authorization code for an access token.
            $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
            $client->setAccessToken($accessToken);

            // Check to see if there was an error.
            if (array_key_exists('error', $accessToken)) {

        if (!file_exists(dirname($tokenPath))) {

    }
    return $client;

Generated token will expire as time pass by. How to refresh token?
