我编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也重定向了所有对图像的请求。所以 index.php 中的所有图像都不起作用。

有没有办法排除 png、pdf 文件被重定向到 index.php 并被显示？尝试了许多在互联网上找到的正则表达式示例，但没有运气。

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

这是具有上述配置的 access.log：

将此添加到您的配置中：

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