我正在尝试编写一个自动将站点升级到当前版本的 Joomla CLI 脚本。在 Joomla 中，这似乎是通过 *com_joomlaupdate* 完成的。这个想法是能够从管理前端升级服务器上的任何 Joomla 站点。

我编写了以下内容进行测试，试图通过直接访问其模型中的方法来模仿 com_joomlaupdate 中的控制器。我不熟悉 joomla 框架，所以我可能会在这里做一些愚蠢的事情。

<?php

const _JEXEC = 1;

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

define('JPATH_BASE', dirname(__DIR__));

require_once JPATH_BASE . '/includes/defines.php';
require_once JPATH_BASE . '/includes/framework.php';

require_once JPATH_LIBRARIES . '/import.legacy.php';
require_once JPATH_LIBRARIES . '/cms.php';

// Load the configuration
require_once JPATH_CONFIGURATION . '/configuration.php';

define('JPATH_COMPONENT_ADMINISTRATOR', JPATH_ADMINISTRATOR . '/components/com_joomlaupdate');

require_once JPATH_COMPONENT_ADMINISTRATOR . '/models/default.php';

class Upgradejoomla extends JApplicationCli
{

        public function doExecute()
        {
                $app = JFactory::getApplication('administrator');
                $app->initialise();
                $app->input->set('method', 'direct');

                $this->out('Fetching updates...');

                $updater = JModelLegacy::getInstance('JoomlaupdateModelDefault');

                $updater->refreshUpdates();

                $updater->applyUpdateSite();

                $basename = $updater->download();

                $app->setUserState('com_joomlaupdate.file', $basename);

                $updater->createRestorationFile($basename);

                echo ($updater->finaliseUpgrade());

                $updater->cleanUp();
        }
}

JApplicationCli::getInstance('Upgradejoomla')->execute();

download()工作正常，我确实得到了最新的文件，并将其放在tmp目录中。createRestorationFile()似乎也可以工作，我在 com_joomlaupdate 目录中得到了一个restore.php文件。

问题似乎与finaliseUpgrade(). 它调用setupInstall()安装程序，尝试查找清单文件。我想我缺少的（除其他外）是该文件（或更新的全部内容）在某处解压缩的步骤。问题是我在 com_joomlaupdate 中找不到任何代码？

我试图在/tmp中手动解压缩更新文件。当我这样做时，finaliseUpgrade()实际上返回 true，但该站点仍保持其旧版本。

好吧，我想通了。

部分更新使用 restore.php 进行（显然取自 Akeeba 备份）。Joomla 对 restore.php 进行了 2 次 ajax 调用，第一次返回一个工厂对象，您必须将其传回。还需要担心 AES CTR 加密。我所做的是使用 curl 来模仿 Joomla 的 ajax 调用。

这是当前的代码。它可能需要进行大量清理工作（不要对 URL 进行硬编码、更多错误检查等），但它确实有效。

好吧，这肯定行不通：

wget -O j3.zip \
    https://github.com/joomla/joomla-cms/releases/download/3.3.6/Joomla_3.3.6-Stable-Full_Package.zip
unzip -o j3.zip

这对于以前版本的 joomla 非常有效:(

我对此更新脚本感兴趣。在您更新的清单中，缺少“class Upgradejoomla extends JApplicationCli”之后的左括号，因此发生了错误。我已经对其进行了测试并放入了一些用于输出状态行的行。它使用 joomla 3.4.0 更新到 3.4.6 进行测试。下载到 /tmp 正在运行，但之后出现状态行但没有任何反应。我放入了一些 $_SERVER 变量以防止 joomla 出错。但我很难理解到底发生了什么……
