nginx配了https后，后端怎么请求http啊

Question

我一个服务器上安了一个nginx，放了一组静态网页，然后配置了https协议，但是静态网页里面

请求的是本机上一个springboot的项目，端口是8080，我现在访问不了接口，nginx怎么配置啊

Answer 1

像这种nginx负载均衡器都是具备https去壳功能，外部请求访问nginx，采用的协议是https，nginx与web服务器是http协议，使用代理就可以了。我贴一个demo配置供参考：

user root root;

worker_processes  8;

error_log /usr/local/nginx/logs/error.log info;

pid     /usr/local/nginx/nginx.pid;

worker_rlimit_nofile 65535;

events {
        use epoll;
        worker_connections  65535;
}

http {
        include       mime.types;
        default_type  application/octet-stream;
        sendfile        on;
        tcp_nopush      on;
        gzip            on;
        keepalive_timeout 30;
        keepalive_requests 10;
        client_header_buffer_size 4k;

        open_file_cache max=65535 inactive=60s;
        open_file_cache_valid 80s;
        open_file_cache_min_uses 1;
        open_file_cache_errors on;

                101.90.254.10/32        0;
        }
        map $whiteiplist $limit{
                1 $binary_remote_addr;

        }

                        check_status;
                }
        }
}
