Nginx只允许某些URL的POST请求

我有一个应用程序将使用GET& POST方法.为了更好的安全性,我已将Nginx配置为仅使用POST请求来服务页面.下面是我在Nginx中使用的配置.

在Nginx中配置：
if($request_method！?^(POST)$){
?返回404; }

这很完美.
现在,我想改变Nginx中的上述配置,以便同时使用GET和amp; POST请求.但是,我无法做到.

我使用了很多组合,但没有运气.

有人可以帮我配置相同的nginx.

下面是我的Nginx配置文件.

注意：我使用Nginx(在前端)作为web服务器和apache(在后端)用于服务应用程序.我已经配置了nginx来成功地将请求的网页重定向到apache.
