我有一个集成了IDP keycloak登录的系统。会话到期的空闲时间设置为20分钟。在这20分钟的空闲时间之后，用户的会话数据自动到期。但是现在我想要一个来自会话的数据从keycloak服务器中删除用户会话。我找不到任何方法来做到这一点。谁能给我一个好的解决方案来在空闲超时后从keycloak中注销用户吗？

$session_data = $this->session->userdata('logged_in');
$idp_data = $this->session->userdata('idp_token');
                     
$ad_data['session_id']=$idp_data['session_state'];  
$logdata=$this->key_logout($ad_data);

public function key_logout($ad_data)
{   
    /* keycloak */
    /* Developer: Kowshiga A
       Created at : 26.8.2021 
       Description: Logout session from IDP  (Oauth flow)  
    */

    $key_token=$this->key_get_token();  
    $ad_data['add_token']=$key_token['access_token']; 
    $this->auth_token1 = 'Authorization: Bearer '.$ad_data['add_token']; 
    $curl = curl_init(); 
    curl_setopt_array($curl, array(
      CURLOPT_URL => $this->keycloak_admin_url.'sessions/'.$ad_data['session_id'],
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_ENCODING => '',
      CURLOPT_MAXREDIRS => 10,
      CURLOPT_TIMEOUT => 0,
      CURLOPT_FOLLOWLOCATION => true,
      CURLOPT_SSL_VERIFYPEER=> FALSE,
      CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
      CURLOPT_CUSTOMREQUEST => 'DELETE',
      CURLOPT_HTTPHEADER => array(
        $this->auth_token1
      ),
    )); 
    $response = curl_exec($curl); 
    curl_close($curl);
    //print_r($response);die;
     return $response;
}
