如何根據Rails應用中的帳戶自動在phpBB3論壇中登錄用戶？

Question

我有一個使用Rails/MySQL作爲後端的移動應用程序（只提供JSON，我知道我們不需要全面的Rails，但這是最簡單的入門解決方案）。我的Rails應用程序使用設計進行身份驗證。我希望我的用戶能夠訪問Phpbb3論壇，而無需再次註冊。什麼是最好的方法來做到這一點？ Phpbb3論壇是否從相同的MySQL中讀取帳戶？

使用電子郵件地址作爲基礎。

名稱的文件中包含/ UCP稱爲ucp_my_rails_app_connect.php

現在我們添加了類ucp.php

case 'register': 
    if ($user->data['is_registered'] || isset($_REQUEST['not_agreed'])) 
    { 
     redirect(append_sid("{$phpbb_root_path}index.$phpEx")); 
    } 

    $module->load('ucp', 'register'); 
    $module->display($user->lang['REGISTER']); 
break; 
case 'my_rails_app_connect': 
    if ($user->data['is_registered']) 
    { 
     redirect(append_sid("{$phpbb_root_path}index.$phpEx")); 
    } 

    $module->load('ucp', 'my_rails_app_connect'); 
    $module->display($user->lang['REGISTER']); 
break; 

現在我們添加一個登錄導軌應用程序

創建一個名爲railsapp.php的文件

$user->session_begin(); 
$auth->acl($user->data); 
$user->setup('ucp'); 

$my_rails_user_email = some_code_to_get_user_email_from_rails_database; //maybe use a cookie or make the user allow the phpBB script access to the rails DB or make them login into the rails app 

$mysql = 'SELECT user_id 
     FROM ' . USERS_TABLE 
     . " WHERE user_email='$my_user_rails_email'"; 
// Execute the query. 
$result = $db->sql_query($sql); 
// Retrieve the row data. 
$row = $db->sql_fetchrow($result); 
// Free up the result handle from the query. 
$db->sql_freeresult($result); 
// Check to see if we found a user_id with the associated Facebook Id. 
if ($row) // User is registered already, let's log him in!

    if($user->check_ban($row['user_id'])) 
    { 
     trigger_error($user->lang['BAN_TRIGGERED_BY_USER']); 
    } 

    // Log user in. 
    $result = $user->session_create($row['user_id'], 0, 0, 1); 

    // Alert user if we failed to log them in. 
    if(!$result) 
    { 
     trigger_error($user->lang['LOGIN_FAILURE']); 
    } 

    $redirect = $phpbb_root_path . 'index.' . $phpEx; 
    $message = ($l_success) ? $l_success : $user->lang['LOGIN_REDIRECT']; 
    $l_redirect = ($admin) ? $user->lang['PROCEED_TO_ACP'] : (($redirect === "{$phpbb_root_path}index.$phpEx" || $redirect === "index.$phpEx") ? $user->lang['RETURN_INDEX'] : $user->lang['RETURN_PAGE']); 
    // append/replace SID (may change during the session for AOL users) 
    $redirect = reapply_sid($redirect); 
    // Special case... the user is effectively banned, but we allow founders to login 
    if (defined('IN_CHECK_BAN') && $result['user_row']['user_type'] != USER_FOUNDER) 
    { 
    return; 
    } 
    $redirect = meta_refresh(3, $redirect); 
    trigger_error($message . '<br /><br />' . sprintf($l_redirect, '<a href="' . $redirect . '">', '</a>')); 
} 
?>
