我第一次在AWS上使用Apache部署了一个Flask应用程序。HTML页面可以加载,但上传文件、写文件和读文件等功能似乎无法正常工作。在下面的示例中,我调用了从URL接收数据并写入的特定函数。但是,在这里,我已经禁用了它,代码只需读取已经存在的文件export_po_list.xml。因此,我已经从终端检查过了。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会显示:
我对这个 Flask 应用所在的整个文件夹执行了 chmod 777 -R 命令,但它仍然无法正常工作。
检查/var/log/apache2/error.log会显示:
IOError: [Errno 13] Permission denied: 'export_po_list.xml'
