，我要打开的文件是myext_key中的JSON文件data.json目录。我的研究告诉我，打开文件的最佳方式不是Resources/Private/JSON，而是file_get_contents($path)。
所以我尝试使用以下代码，但这不起作用：
\TYPO3\CMS\Core\Utility\GeneralUtility::getURL($path)感谢您的帮助！
答案 0 :(得分：5)
不确定file_get_contents()是否有任何问题，而不是内存含义，因为file_get_contents()基本上会为整个文件内容分配一个变量。只要你处理一个小的.json文件很小就应该放在安全的地方。
获取扩展目录中文件的绝对文件名的方法是getFileAbsFileName()
$content = file_get_contents(
\TYPO3\CMS\Core\Utility\GeneralUtility::getFileAbsFileName('EXT:myext_key/Resources/Private/JSON/data.json'
);
