Nginx 重定向除了一些扩展

Question

我写了一个配置强制门户的脚本，一切正常。我遇到的问题是因为 nginx 将所有请求重定向到 http://hotspot.localnet/index.php 也将所有请求重定向到图像。因此 index.php 中的 none 个图像有效。

有没有办法阻止 png、pdf 文件被重定向到 index.php 并显示？尝试了很多在互联网上找到的正则表达式示例，但没有成功。

nginx 配置文件的源代码在这里：https://github.com/tretos53/Captive-Portal/blob/master/default_nginx

这是 access.log 以上配置：

将此添加到您的配置中：

    location ~ \.(?:pdf|png)$ {
        try_files $uri =404;
    }
