之前忘了调强制301 https跳转，今天想起来想要做，但是发现了新的做法：在index.php里添加跳转代码，而不是在nginx的conf文件里添加，可以节省资源：
1
if(!((isset($_SERVER['HTTPS'])&&$_SERVER['HTTPS']=='on')||(isset($_SERVER['HTTP_X_FORWARDED_PROTO'])&&$_SERVER['HTTP_X_FORWARDED_PROTO']=='https'))){ Header("HTTP/1.1 301 Moved Permanently"); header('Location: https://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']); }
