您好,我想从这里学到一些东西,基本上我想让我的系统访问谷歌帐户以某种方式我设法做以下
但我觉得我在某些方面做错了,这是Oauth2callback
class Oauth2callback extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->helper('url');
$this->load->library('session');
require_once APPPATH.'libraries/Google/Client.php';
session_start();
}
public function index()
{
$client_id = $this->config->item('client_id');
$client_secret = $this->config->item('client_secret');
$redirect_uri = $this->config->item('redirect_uri');
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://www.googleapis.com/auth/userinfo.email");
$client->addScope("https://www.googleapis.com/auth/userinfo.profile");
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['access_token'] = $client->getAccessToken();
$redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
$client->setAccessToken($_SESSION['access_token']);
} else {
$authUrl = $client->createAuthUrl();
}
if ($client->getAccessToken()) {
$_SESSION['access_token'] = $client->getAccessToken();
}
if(isset($authUrl)) {
header('location:'. base_url());
}else{
header('location:'. base_url().'dashboard');
}
}
但这是我的索引控制器Login
它只有按钮sign in with Google
class Login extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->helper('url');
$this->load->library('session');
require_once APPPATH.'libraries/Google/Client.php';
session_start();
}
public function index()
{
//$this->checkSession();
$client_id = $this->config->item('client_id');
$client_secret = $this->config->item('client_secret');
$redirect_uri = $this->config->item('redirect_uri');
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://www.googleapis.com/auth/userinfo.email");
$client->addScope("https://www.googleapis.com/auth/userinfo.profile");
$authUrl = $this->data['authUrl'] = $client->createAuthUrl();
$this->load->view('login/index.php',$this->data);
$this->load->view('template/pre_footer');
$this->load->view('template/footer');
}
}
使用MVC PHP的正确过程是什么我需要做ff。 :
A.单击按钮sign in to google
B.获取令牌并将其保存到会话中
C.将令牌用于我的整个系统(在每个控制器中)
我现在所拥有的是A& B但C我完全不知道该怎么做。
任何人都可以帮助我。任何建议评论都很受欢迎。提前谢谢。

您拥有的代码可能会有点混乱,因为它处理授权网址,重定向到Google,回调到您的网站,并同时保存访问令牌。
当使用访问令牌对api执行经过身份验证的调用时,它更加简单。如果您在会话中存储了有效的访问令牌,您可以在任何地方使用它来初始化Google应用程序,这样:
// client
$client = new Google_Client();
$client->setApplicationName('Google Application');
$client->setClientId($clientId);
$client->setClientSecret($clientSecret);
$client->setRedirectUri($redirectUri);
// token
$client->setAccessToken($token);
现在,如果您希望在多个控制器上使用它,CodeIgniter中最合适的方法是创建一个包含上述代码的新库。
使用库的优点是它们可以在CodeIgniter配置中自动加载,并且可以在代码中的任何位置轻松访问。
示例库:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Someclass {
private $client;
public function __construct()
{
...
// client
$client = new Google_Client();
$this->client->setApplicationName('Google Application');
$this->client->setClientId($clientId);
$this->client->setClientSecret($clientSecret);
$this->client->setRedirectUri($redirectUri);
// token
$this->client->setAccessToken($token);
}
}
?>
然后你必须这样做才能在你的控制器中使用它:
$this->load->library('someclass');
您还可以创建特定API的快捷方式。例如,如果您想快速访问Google AnalyticsAPI,可以执行以下操作:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Someclass {
private $client;
public function __construct()
{
...
// client
$client = new Google_Client();
$this->client->setApplicationName('Google Application');
$this->client->setClientId($clientId);
$this->client->setClientSecret($clientSecret);
$this->client->setRedirectUri($redirectUri);
// token
$this->client->setAccessToken($token);
}
public function analytics()
{
return new Google_Service_Analytics($this->client);
}
}
?>
然后在你的控制器中以这种方式使用它:
$this->load->library('someclass');
$this->someclass->analytics();
