Methods

uri

Return OAuth2 authentication URI

string uri ( string $endpoint = NULL, bool $query = TRUE )

Useful for generating an authentication uri to display to the end user. For instance:

$fw = Base::instance();
$Oauth = new \Web\OAuth2();
$Oauth->set('client_id', $fw->get('google.client_id'));
$Oauth->set('scope', 'profile email');
$Oauth->set('response_type', 'code');
$Oauth->set('access_type', 'online');
$Oauth->set('approval_prompt', 'auto');
$Oauth->set('redirect_uri', $fw->SCHEME.'://' . $_SERVER['HTTP_HOST'] . '/oauthRedirect');
echo $Oauth->uri('https://accounts.google.com/o/oauth2/auth', true);

request

Send request to API/token endpoint

string uri ( string $uri, string $method, string $token = NULL )

This sends off the request to the endpoint specified. $token is the access token to be included in the Authorization header. Below is an example of a request.

$fw = Base::instance();
$Oauth = new \Web\OAuth2();
$Oauth->set('client_id', $fw->get('google.client_id'));
$Oauth->set('client_secret', $fw->get('google.client_secret'));
$Oauth->set('scope', 'profile email');
$Oauth->set('access_type', 'online');
$Oauth->set('grant_type', 'authorization_code');
$Oauth->set('code', $auth_code);
$Oauth->set('approval_prompt', 'auto');
$Oauth->set('redirect_uri', $fw->SCHEME.'://' . $_SERVER['HTTP_HOST'] . '/oauthRedirect');
$token = $Oauth->request('https://oauth2.googleapis.com/token', 'POST');

// now you can make requests with that token
$Oauth_User_Info = new \Web\OAuth2();
echo $Oauth_User_Info->request('https://www.googleapis.com/oauth2/v2/userinfo', 'GET', $token['access_token']);
