Typo3 使用eID连接到数据库

我有一个小问题：

---

如何将扩展中的eid脚本连接到MySQL数据库？这样做的最佳做法是什么？

这应该是一个很好的起点：

<?php

/**
 * @var $TSFE \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController
 */
$TSFE = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController', $TYPO3_CONF_VARS, 0, 0);
\TYPO3\CMS\Frontend\Utility\EidUtility::initLanguage();

// Get FE User Information
$TSFE->initFEuser();
// Important: no Cache for Ajax stuff
$TSFE->set_no_cache();

$TSFE->checkAlternativeIdMethods();
$TSFE->determineId();
$TSFE->initTemplate();
$TSFE->getConfigArray();
\TYPO3\CMS\Core\Core\Bootstrap::getInstance()->loadConfigurationAndInitialize();

$TSFE->cObj = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer');
$TSFE->settingLanguage();
$TSFE->settingLocale();

/**
 * Initialize Database
 */
\TYPO3\CMS\Frontend\Utility\EidUtility::connectDB();

?>

如果您想使用eID处理Extbase，应该阅读以下内容，因为不建议在需要大量数据库请求的应用程序中使用eID

$GLOBALS['TYPO3_CONF_VARS']['FE']['eID_include']['sha1Converter'] = 'EXT:myext/Classes/Eid/myEidFile.php';
