nginx 反向代理时丢失端口的解决方案

        listen       8030;
        server_name  localhost;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host:$server_port; #这里是重点,这样配置才不会丢失端口
        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location /api {
            root  G:\360MoveData\Users\Administrator\Desktop\code\MicaSpace\micaspace\dist;
            index  index.html index.htm;
            proxy_pass http://111.231.112.75:8080/api;
            proxy_redirect http://$host:8080/ http://$host:$server_port/; 
            proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header Host $host:$server_port; 
        }
