如何查看“google drive api”文件列表中的路径

Question

I have followed https://developers.google.com/drive/api/v2/reference/files/list, successful! I got it all. But not my 'drive'. I received a warning 'You need to be granted access here. So what should I do to fix the above error?

I created a new project, Service account keys and OAuth 2.0 client IDs. but it's bad it doesn't properly link to my 'google drive' account

This is my whole code

<?php
    session_start ();

    require_once 'google-api-php-client/src/Google_Client.php';
    require_once 'google-api-php-client/src/contrib/Google_DriveService.php';
    require_once 'google-api-php-client/src/contrib/Google_Oauth2Service.php';
    require_once 'vendor/autoload.php';

    $DRIVE_SCOPE = 'https://www.googleapis.com/auth/drive';
    $SERVICE_ACCOUNT_EMAIL = '[e-mail]';
    $SERVICE_ACCOUNT_PKCS12_FILE_PATH = 'phim-240702-a98343eb742a.p12';

    function buildService(){
      global $DRIVE_SCOPE, $SERVICE_ACCOUNT_EMAIL, $SERVICE_ACCOUNT_PKCS12_FILE_PATH;
      $key = file_get_contents($SERVICE_ACCOUNT_PKCS12_FILE_PATH);
      $auth = new Google_AssertionCredentials(
        $SERVICE_ACCOUNT_EMAIL,
        array($DRIVE_SCOPE),
        $key);

    $client = new Google_Client();

    $client->setApplicationName("googletest5");
    $client->setDeveloperKey("b2016fa55e916faf35337ccb1db830ecdb590cc3");
    $client->setUseObjects(true);
    $client->setAssertionCredentials($auth);
    return new Google_DriveService($client);
    }

Answer 1

What you need to remember is that a Service account is not you. A service account is a dummy user. It has its own google drive account. when you upload the files to the service accounts drive account they are only accessible by that account as it is the owner of it.

Share a drive

If you want it to be able to access files on your personal drive account you will need to grant it access to them by sharing them with the service accounts email address. This is how service accounts are pre approved.

getting path

As for getting the path of a file there is no easy way to do that you will need to step your way though it by getting the file, then getting its parent, followed by getting any more parents until you hit the top and build it up that way.
