来自外部应用程序的 Joomla 登录身份验证 [英] Joomla Login Authentication from external app

问题描述

我需要从我的外部应用程序中检查 Joomla 用户名 和密码 是否有效.用户不必在其帐户存在时登录系统.我该怎么做?

I need to check that a Joomla username and password is valid from my external application. It is not necessary that the user is logged into the system just that their account exists. How do I do this?

推荐答案

我假设您的外部应用程序可以访问 Joomla 的数据库，并且也是用 php 编写的.

I'm supposing your external application will have access to Joomla's database and is written in php as well.

我已经回答了一个关于 在 joomla 之外创建用户，您可以使用相同的方法，但不是从 JUser 调用 save 方法，你可以使用bind来检查密码是否正确.

I've already answered a similar question about creating a user outside joomla, you could use the same approach, but instead of calling the save method from JUser, you could use bind to check if the password is correct.

或者更好的:在创建Joomla 外的环境"！检查JOOMLA_PATH/plugins/authentication/joomla.php:

 function onAuthenticate( $credentials, $options, &$response ){
  jimport('joomla.user.helper');
  // Joomla does not like blank passwords
  if (empty($credentials['password'])){
   $response->status = JAUTHENTICATE_STATUS_FAILURE;
   $response->error_message = 'Empty password not allowed';
   return false;
  }

  // Initialize variables
  $conditions = '';

  // Get a database object
  $db =& JFactory::getDBO();

  $query = 'SELECT `id`, `password`, `gid`'
   . ' FROM `#__users`'
   . ' WHERE username=' . $db->Quote( $credentials['username'] )
   ;
  $db->setQuery( $query );
  $result = $db->loadObject();

  if($result){
   $parts = explode( ':', $result->password );
   $crypt = $parts[0];
   $salt = @$parts[1];
   $testcrypt = JUserHelper::getCryptedPassword($credentials['password'], $salt);

   if ($crypt == $testcrypt) {
    $user = JUser::getInstance($result->id); // Bring this in line with the rest of the system
    $response->email = $user->email;
    $response->fullname = $user->name;
    $response->status = JAUTHENTICATE_STATUS_SUCCESS;
    $response->error_message = '';
   } else {
    $response->status = JAUTHENTICATE_STATUS_FAILURE;
    $response->error_message = 'Invalid password';
   }
  }
  else{
   $response->status = JAUTHENTICATE_STATUS_FAILURE;
   $response->error_message = 'User does not exist';
  }
 }
