Question

我在codeigniter 3中遇到了Facebook Auth的问题。每当我按下facebook登录时，它会重定向到facebook请求权限，而den会返回链接中的代码，而不会将其重定向到我的个人资料页面。以下是我的控制器

<?php defined('BASEPATH') OR exit('No direct script access allowed');
class User_Authentication extends CI_Controller
{
    function __construct() {
        parent::__construct();

        // Load facebook library
        $this->load->library('facebook');

        //Load user model
        //$this->load->model('user');
    }

    public function index(){
        $userData = array();

        // Check if user is logged in
        if($this->facebook->is_authenticated()){
            // Get user facebook profile details
            $userProfile = $this->facebook->request('get', '/me?fields=id,first_name,last_name,email,gender,locale,picture');

            // Preparing data for database insertion
            $userData['oauth_provider'] = 'facebook';
            $userData['oauth_uid'] = $userProfile['id'];
            $userData['first_name'] = $userProfile['first_name'];
            $userData['last_name'] = $userProfile['last_name'];
            $userData['email'] = $userProfile['email'];
            $userData['gender'] = $userProfile['gender'];
            $userData['locale'] = $userProfile['locale'];
            $userData['profile_url'] = 'https://www.facebook.com/'.$userProfile['id'];
            $userData['picture_url'] = $userProfile['picture']['data']['url'];

            // Insert or update user data
            $userID = $this->user->checkUser($userData);

            // Check user data insert or update status
            if(!empty($userID)){
                $data['userData'] = $userData;
                $this->session->set_userdata('userData',$userData);
            } else {
               $data['userData'] = array();
            }

            // Get logout URL
            $data['logoutUrl'] = $this->facebook->logout_url();
        }else{
            $fbuser = '';

            // Get login URL
            $data['authUrl'] =  $this->facebook->login_url();
        }

        // Load login & profile view
        $this->load->view('user_authentication/index',$data);
    }

    public function logout() {
        // Remove local Facebook session
        $this->facebook->destroy_session();
        // Remove user data from session
        $this->session->unset_userdata('userData');
        // Redirect to login page
        redirect('/user_authentication');
    }
}

以下是我在config.php中的facebook文件

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

/*

|
| To get an facebook app details you have to be a registered developer

*/

$config['facebook_app_id']              = '******';
$config['facebook_app_secret']          = '*****';
$config['facebook_login_type']          = 'web';
$config['facebook_login_redirect_url']  = 'user_authentication';
$config['facebook_logout_redirect_url'] = 'user_authentication/logout';
$config['facebook_permissions']         = array('email');
$config['facebook_graph_version']       = 'v2.6';
$config['facebook_auth_on_load']        = TRUE;

每当我按下facebook登录时，它会要求获得权限，然后在链接栏中使用代码将我扔回同一页面。登录前

http://localhost/bird_eye_api/user_authentication

登录后

http://localhost/bird_eye_api/user_authentication?code=AQBWssEFr4IVgC9gMBX3QUR_v7bSWU2F2Lj59-u89tRdSJTuinJNN3f9EC35F1yR8uWMeMq4JvQRlDk982sddLz5jJymqhh537WlyGYNv8mHnpIW3qhggSKwm3AEGiujf9jtD54FJGzM5OzAY-QF1GTnmHa3EiO_ZsF-iQKqlLYv3NfCd30U2004Dbw6OsYLFPLsuRFpgEkA3J2XTxPpWHPVhX2TDGEFU72qXqTcuaYWCrrOFvZBCbwVziXL9Run13W8ZBZ84rOjJKar-Pwh9v4pztJ0OG3SYLsK3OiTZoMGjQ8Gcb_dohJ0d5b5383lUdk&state=663d1106ff10826c01b08c4f1d1933d8#_=_

回调网址有什么问题吗？

Answer 1

只需更改

$config['facebook_login_redirect_url']

在你的config.php中你想要返回的网页的网址。

例如：

$config['facebook_login_redirect_url']  = 'profile';

不要忘记在此页面上处理Facebook代码。这就像http://yoursite.com/bird_eye_api/profile?code=AABCCDDEEFF
