在Nginx

Question

我试图美化我的获取变量。我的PHP代码需要两个get变量：cam和res。现在它的网站正常运作：

http://stream.foo.bar?cam=camera1&res=low

我希望能够做类似的事情：

http://stream.foo.bar/camera1/low/

我正在使用nginx，我在下面包含了我的配置以及一些日志行。任何帮助将不胜感激。

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;

       location /stream/ {
            root /tmp/hls/;
         index stream.m3u8;
         types {
               application/vnd.apple.mpegurl m3u8;
         }
    }
    location / {
         root /opt/streaming/www/;
         try_files $uri $uri/ @pretty;
}
    location /hawk {
         rewrite ^/hawk(.*) http://stream.foo.bar/?cam=hawkcam&res=low;
         }

        location @pretty {
    rewrite ^/([^/]+)/([^/]+)/$ /index.php?cam=$1&res=$2 last;
    }
}
server {
       listen 80;
       server_name hawk.foo.bar;
       return 301 $scheme://stream.foo.bar;
       }
server {
     listen 8080;
     server_name localhost;
     location /nginx_status {
      stub_status on;
      access_log /var/log/nginx/access.log;
      allow 127.0.0.1;
      allow 192.168.41.0/24;
      deny all;
     }
}

我忘了添加nginx error.log行。当我尝试去stream.foo.bar/baycam1/high/时出现以下错误：

显然，重写并不像我期望的那样正常工作。
