最初にopenid.phpをダウンロードし、codeigniterのルートフォルダに入れてください。
1コピーコードと.... /コントローラ/ logingoogle.php
<?php if (! defined('BASEPATH')) exit('No direct script access allowed');
class LoginGoogle extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('login_model');
}
public function index()
{
require_once 'openid.php';
$openid = new LightOpenID("localhost");
$openid->identity = 'https://www.google.com/accounts/o8/id';
$openid->required = array(
'namePerson/first',
'namePerson/last',
'contact/email',
'birthDate',
'person/gender',
'contact/postalCode/home',
'contact/country/home',
'pref/language',
'pref/timezone',
);
// $openid->returnUrl = 'http://localhost/login_thirdparty/login_google.php';
$openid->returnUrl = 'http://localhost/login_thirdparty/codeigniterlogin/index.php/logingoogle/loginAuth';
// echo '<a href="'.$openid->authUrl().'">Login with Google</a>';
$data['openid'] = $openid;
$this->load->view('googleLoginView', $data);
}
public function loginAuth()
{
$this->login_model->index();
}
}
2コピーとしてコードを保存し、.... /ビュー/ googleLoginView.phpとして保存
<!DOCTYPE html>
<html lang="en">
<head>
<title>Login using google account</title>
</head>
<body>
<a href = "<?php echo $openid->authUrl(); ?>" > Loging Using google account </a>
</body>
</html>
3.コピーコードと名前を付けて保存... /モデル/ login_model.php
<?php if (! defined('BASEPATH')) exit('No direct script access allowed');
require 'openid.php';
class Login_model extends CI_Model
{
public function index()
{
$openid = new LightOpenID("localhost");
if($openid->mode)
{
if($openid->mode == 'cancel')
{
echo "User has canceled authentication !";
}
elseif($openid->validate())
{
$data = $openid->getAttributes();
$email = $data['contact/email'];
$first = $data['namePerson/first'];
// header("Location: http://speechwithmilo.com/speechtherapy/adminpanel/");
echo "Identity : $openid->identity <br />";
echo "Email : $email <br />";
echo "First name : $first";
echo "<pre>"; print_r($data); echo "</pre>";
// echo "<meta http-equiv = 'refresh' content = '0; url=http://speechwithmilo.com/speechtherapy/adminpanel/'>";
}
else
{
echo "The user has not logged in";
}
}
else
{
echo "Go to the login page to logged in";
}
}
}
Googleは2015年4月以来、OpenID Connectによるログインを廃止したことを認識しています。これはかなり後継です。https://developers.google.com/identity/protocols/OpenID2Migration –
