使用说明

将Oauth2.php和oauth2文件夹扔进libraries里
application/config建立oauth2.php，内容如下

//xx代表每个provider的唯一标识，也就是文件名的小写
$config['oauth2']['xx'] = array(
	'id' => 'your app client id',
	'secret' => 'your app client secret'
);
$config['oauth2']['xxx'] = array(
	'id' => 'your app client id',
	'secret' => 'your app client secret'
);

典型的控制器代码

<?php defined('BASEPATH') OR exit('No direct script access allowed');

class Sns extends CI_Controller {

    public function __construct()
    {
          parent::__construct();
        $this->session->userdata('is_login') AND redirect();
    }

    public function session($provider = '')
    {
        $this->config->load('oauth2');
        $allowed_providers = $this->config->item('oauth2');
        if ( ! $provider OR ! isset($allowed_providers[$provider]))
        {
            $this->session->set_flashdata('info', '暂不支持'.$provider.'方式登录.');
            redirect();
            return;
        }
        $this->load->library('oauth2');
        $provider = $this->oauth2->provider($provider, $allowed_providers[$provider]);
        $args = $this->input->get();
        if ($args AND !isset($args['code']))
        {
            $this->session->set_flashdata('info', '授权失败了,可能由于应用设置问题或者用户拒绝授权.<br />具体原因:<br />'.json_encode($args));
            redirect();
            return;
        }
        $code = $this->input->get('code', TRUE);
        if ( ! $code)
        {
            $provider->authorize();
            return;
        }
        else
        {
            try
            {
                $token = $provider->access($code);
                $sns_user = $provider->get_user_info($token);
                if (is_array($sns_user))
                {
                    $this->session->set_flashdata('info', '登录成功');
                    $this->session->set_userdata('user', $sns_user);
                    $this->session->set_userdata('is_login', TRUE);
                }
                else
                {
                    $this->session->set_flashdata('info', '获取用户信息失败');
                }
            }
            catch (OAuth2_Exception $e)
            {
                $this->session->set_flashdata('info', '操作失败<pre>'.$e.'</pre>');
            }
        }
        redirect();
    }
}
