Google Drive API installation procedure using PHP Quickstart

Aug 24, 2020 PHP Beginner GoogleDrive

I used Google Drive API, so I have a memo

Set up connection using Quickstart

Install Google Client Library

composer require google/apiclient:^2.0

Download credentials

*If you have already set up the OAuth 2.0 client (If not set, set OAuth 2.0 client first)

Creating a sample program

PHP Quickstart | Google Drive API | Google Developers

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 Drive API PHP Quickstart'); //Specify the set application name
    $client->setAuthConfig('credentials.json'); //JSON path obtained here
    $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
    // time.
    $tokenPath ='token.json';
    if (file_exists($tokenPath)) {
        $accessToken = json_decode(file_get_contents($tokenPath), true);

Executing the sample program

php quickstart.php
[hoge@hogehoge hoge]$ php quickstart.php
