PHP: Can I use account and password to authorize a google-api-client connection?

Question

In Google Docs api guide, Oauth2 are provided as an authorization method. Here are the authorization code:

$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('...');
$client->setClientSecret('...');
$client->setRedirectUri('urn:ietf:wg:oauth:2.0:oob');
$client->setScopes(array('https://www.googleapis.com/auth/drive'));

$service = new Google_DriveService($client);

$authUrl = $client->createAuthUrl();

// Request authorization
print "Please visit:\n$authUrl\n\n";
print "Please enter the auth code:\n";
$authCode = trim(fgets(STDIN));

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

However, this kind of authorization requires you to click the link and authorize it manually. What I want is to use email account and password to authorize the connection, is that possible?

BTW, I do not want to use Zend-Gdata. Thanks in advance.

Answer 1

You can use a service account.

For these types of server-to-server interactions you need a service account, which is an account that belongs to your application instead of to an individual end-user. Your application calls Google APIs on behalf of the service account, and user consent is not required. (In non-service-account scenarios, your application calls Google APIs on behalf of end-users, and user consent is sometimes required.)

Here's a sample code using the PHP lib.
