我第一次在 AWS 上使用 Apache 部署了一个 Flask 应用程序。加载了 HTML 页面,但是上传文件、写入文件和读取文件等操作似乎不起作用。在下面的示例中,我调用了这个特定函数来写入从 URL 接收到的数据。但在这里,我禁用了它,代码只需要读取已经存在的文件。所以,export_po_list.xml 已经存在,我已经从终端检查过它。同样的代码在我的电脑上本地运行得很好。

检查 /var/log/apache2/error.log 显示

IOError: [Errno 13] Permission denied: 'export_po_list.xml'

我对包含这个 flask 应用程序的整个文件夹执行了 chmod 777 -R。还是不行。
