Question

我正在尝试为我的2.5 Joomla网站的Android应用程序创建一个登录系统。我试图通过制作一个Joomla插件来实现这一点，Android应用程序将发布数据发送到php文件，然后验证用户是否正确登录凭据。我一直试图让这个工作整个下午，但似乎我所有导入JFactory的尝试都失败了。

我在第一次提到JFactory时遇到了以下代码。我尝试导入它也不起作用。

<?php
//needed to be commented out otherwise the android application cannot send data to the file
//defined('_JEXEC') or die;

define('_JREQUEST_NO_CLEAN', 1); 
define('_JEXEC', 1);
define('DS', DIRECTORY_SEPARATOR);

if (file_exists(dirname(__FILE__) . '/defines.php')) {
    include_once dirname(__FILE__) . '/defines.php';
}

if (!defined('_JDEFINES')) {
    define('JPATH_BASE', dirname(__FILE__));
    require_once JPATH_BASE.'/includes/defines.php';
}

require_once JPATH_BASE.'/includes/framework.php';
require_once JPATH_BASE.'/includes/helper.php';
require_once JPATH_BASE.'/includes/toolbar.php';
require JPATH_BASE.'/library/joomla/factory.php';

$email = $_POST['email'];
$password = $_POST['password'];
file_put_contents("Log.txt", "got data: ".$email." and ".$password);
$credentials->email = $email;
$credentials->password = $password;
$responce;

//error occurs here
$db     = JFactory::getDbo();
...
?>

我已经查看了有关导入JFactory的其他问题，但没有一个对我有用：
- JFactory,JDatabase class not found in /var/www/joomla2.5/database.php
- Class 'JFactory' not found
- include Jfactory class in an external php file, Joomla

所以我的简化问题是如何导入JFactory或至少在这种情况下解决它？任何比我更聪明的人都会如此友善地回答这个问题:)

我建议采用正式的Joomla方式并启动应用程序。我做的很好，是推荐的Joomla方式（我没有测试下面的代码，但它应该给你一个起点，因为它是我的代码中来自多个来源的复制粘贴）。

define('_JEXEC', 1);
define('DS', DIRECTORY_SEPARATOR);

error_reporting(E_ALL | E_NOTICE);
ini_set('display_errors', 1);

define('JPATH_BASE', dirname(dirname(dirname(__FILE__))));
require_once JPATH_BASE.DS.'includes'.DS.'defines.php';
require JPATH_LIBRARIES.DS.'import.php';
require JPATH_LIBRARIES.DS.'cms.php';

JLoader::import('joomla.user.authentication');
JLoader::import('joomla.application.component.helper');

class MyJoomlaServer extends JApplicationWeb {

    public function doExecute() {
        $config = JFactory::getConfig();
        $email = $_POST['email'];
        $password = $_POST['password'];
        $user = ...;//get the user with the email
        file_put_contents("Log.txt", "got data: ".$email." and ".$password);
        $authenticate = JAuthentication::getInstance();
        $response = $authenticate->authenticate(array('username' => $user->username, 'password' => $password));

        return $response->status === JAuthentication::STATUS_SUCCESS;
    }

    public function isAdmin() {
        return false;
    }
}

$app = JApplicationWeb::getInstance('MyJoomlaServer');
JFactory::$application = $app;
$app->execute();

有些东西适用于我。可在此处找到更多平台示例https://github.com/joomla/joomla-platform-examples/tree/master/web。

Answer 2

试试这个，

define( '_JEXEC', 1 );
define('JPATH_BASE', dirname(__FILE__) );//this is when we are in the root
define( 'DS', DIRECTORY_SEPARATOR );

require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );

$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
$db     = JFactory::getDbo();

它会工作，你错过了JFactory::getApplication('site');

希望有所帮助......
