有时候代理规则是可以重用的,可以使用如下方式

location / {
            proxy_pass http://127.0.0.1:8080;
            include proxy_params;
    }

proxy\_params文件内容

proxy_redirect default;
    
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    
    proxy_connect_timeout 30;
    proxy_send_timeout 60;
    proxy_read_timeout 60;
    
    proxy_buffer_size 32k;
    proxy_buffering on;
    proxy_buffers 4 128k;
    proxy_busy_buffers_size 256k;
    proxy_max_temp_file_size 256k;
