哗啦啦！2.5.19 外部用户登录 - Joomla! 2.5.19 external user login

不幸的是，我找不到与这个Joomla！版本相关的主题。在尝试了几个代码后，我决定打开一个新主题，请问这里的专家。:)

我们使用具有基本身份验证检查的脚本。在我们更新到Joomla之后！2.5.19，旧的 MD5 方法不再有效。PHP 脚本如下：

session_start();
    $db = mysql_connect("localhost", "root", "");
    mysql_select_db("sql1",$db);
//Joomla user and pass check start
$sql = "SELECT * FROM j25_users WHERE username='".$_POST['user']."'";
$result = mysql_query($sql,$db); 
$userdata = mysql_fetch_array($result);
list ($md5pass, $saltpass) = split (":", $userdata['password']);
$POSTPW = crypt ( 'xxgu952rjyiL', 'Xh2loHgxxi5ijuNbGI' );

echo "<br><br>";
$joomlapw=$userdata[password];
echo "POST PW= $POSTPW
<br>
Joomla - PW = $joomlapw
<br>
salt = $saltpass
<br>
";
if(((md5($_POST['pa'].$saltpass))==$md5pass) and ($userdata['usertype']=="Super Administrator" or $userdata['usertype']=="Editor"))
{
echo "success!";
  $jommlapruefung="success";
}
echo "<br>$_POST[user] und $_POST[pa]";

//Joomla user and pass check complete
$dom        =str_replace("lager.","",$_SERVER["HTTP_HOST"]);

$_GET['getdir']=str_replace(chr(92),"",$_GET['getdir']);
$_GET['getdir']=str_replace("//","/",$_GET['getdir']); 
$_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']); $_GET['getdir']=str_replace("//","/",$_GET['getdir']);
$_GET['getdir']=str_replace(".","_",$_GET['getdir']);
if ($_GET['getdir']==NULL) $_GET['getdir']="/";
if  ( ($_GET['getdir']=="") || ($_GET['getdir']=="/") )
 {
 if ($jommlapruefung!="success" & $_SESSION['best']!='gogo') 
  {
  die("<FORM ACTION=index.php METHOD=POST>
        Username:&nbsp; <INPUT TYPE=text NAME=user LENGTH=25 SIZE=25>
        Password:&nbsp; <INPUT TYPE=password NAME=pa LENGTH=25 SIZE=25>
        <input type='submit' name='submit' value='Submit'><br>
       </FORM>");
  }
 }
if ($jommlapruefung="success") 
  {
    $_SESSION['best'] = 'gogo';
  }
if($_SESSION['best']='gogo')
{
// HERE COMES THE SCRIPT AFTER LOGIN!!
// ...
}
?>

这段代码已经有几年的历史了，不是我创建的。一些细节被清除了。您知道如何将此脚本从 md5 更新到 bcrypt 身份验证吗？我感谢你对我的帮助！:)

我不确定我是否完成了你的问题。但是，如果您尝试使用其他网站上的表单登录joomla，则可以在joomla的根目录下创建一个脚本，例如joomlalogin.php如下所示：

第一部分启动 joomla 接口：

// START: Initialize Joomla framework
define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
define('JPATH_BASE', dirname(__FILE__) );
// Including Required Files
require_once ( JPATH_BASE.DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE.DS.'includes'.DS.'framework.php' );
// Create the Application
$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
$user =& JFactory::getUser();
// END: Initialize Joomla framework

然后验证并登录用户：

$app = JFactory::getApplication();
// Populate the data array:
$data = array();
$data['return'] = base64_decode(JRequest::getVar('return', '', 'POST', 'BASE64'));  //Page user is returned to after a successfull login
$data['username'] = JRequest::getVar('username', '', 'method', 'username');
$data['password'] = JRequest::getString('password', '', 'post', JREQUEST_ALLOWRAW);
// Set the return URL if empty.
if (empty($data['return'])) {
    $data['return'] = 'index.php';  //If return page not set... set one.
}
// Set the return URL in the user state to allow modification by plugins
$app->setUserState('users.login.form.return', $data['return']);
// Get the log in options.
$options = array();
$options['remember'] = JRequest::getBool('remember', false);
$options['return'] = $data['return'];
// Get the log in credentials.
$credentials = array();
$credentials['username'] = $data['username'];
$credentials['password'] = $data['password'];
// Perform the log in.
if (true === $app->login($credentials, $options)) {
    // Success
    $app->setUserState('users.login.form.data', array());
    $app->redirect(JRoute::_($app->getUserState('users.login.form.return'), false));
} else {
    // Login failed !
    $data['remember'] = (int)$options['remember'];
    $app->setUserState('users.login.form.data', $data);
    $app->redirect('index.php', false));
}

我没有测试过这个代码片段。我只是使用现有网站为您放置这个togetter。因此，如果您遇到问题或我是否应该改进/修复我的答案，请告诉我。

您无法解密 joomla 数据库中的密码。但是您可以使用此方法对其进行验证。这将创建Session Cookie，将用户登录到安装Joomla的同一域上的Joomla。
