Question

我非常困在这里。我正在尝试使用Facebook Graph api构建应用程序，以便用户可以登录。

我已经在我的php框架（codeigniter）中对其进行了结构化。但是无论如何，无论何时尝试登录，我都会无所适从。

我已经在每个可能的返回值的地方调试了它，并成功返回了正确的值，但是每当渲染视图时，它都会重定向到注销功能，并且在尝试任何登录后都会注销。

配置文件

$config['fbAppId'] = 'somenumbers';
$config['fbAppSecret'] = 'somenumbers';
$config['fbLoginType'] = 'web';
$config['fbLoginRedirectURL'] = 'posts/add_a_post/';
$config['fbLogoutRedirectURL'] = 'posts/logout/';
$config['fbPermissions'] = array('email', 'user_gender');
$config['fbGraphVersion'] = 'v3.1';
$config['fbAuthOnLoad'] = TRUE;

后置控制器

public function add_a_post()
{
    if( strlen( $this->input->post( 'isSecured' ) ) > 0 ):
        $jumper_text = $this->input->post( 'isSecured' );
        $is_secured = $this->Posts_Model->check_secure_jumper( $jumper_text );
        if( $is_secured === $this->nextPhaseToken ):
            $view_data['categories'] = $this->Posts_Model->get_data('category');
            $view_data['id'] = $this->input->post( 'id' );
            $view_data['allFiles'] = $this->Posts_Model->get_data($this->filesTbl, array(
                "advert_id" => $view_data['id']
            ), 'DESC');
            $this->load->view( 'gen_users/advertisment_posting_view_second', $view_data );
        else:
            echo "<pre>"; var_dump( $is_secured ); echo "</pre>";
        endif;
    else:

        $loginData = $this->register();
        // echo "<pre>";var_dump( $loginData );echo "</pre>";
        // exit;
        $primary_key = 'id';

        $view_data['divisions'] = $this->Posts_Model->get_data('divisions');
        $view_data['loginData'] = $loginData;
        // var_dump($this->session->all_userdata());
        // echo "<pre>"; var_dump($view_data); echo "</pre>";
        // exit();
        $this->load->view('gen_users/advertisment_posting_view', $view_data);
    endif;

public function register()

    $data = array();

    $this->load->library('Facebook');

    $userData = array();

    // Check if user is logged in
