场景：内网开放后端端口8088，前端nginx内网开放8080，需要做外网映射，但是只能映射一个端口8080

问题：如何外网访问时统一前后端端口为8080

方案：修改nginx配置和sso配置

nginx配置：

upstream api{
		server 10.*.*.*:8088;//内网ip和后端端口
	}

location /api {
			rewrite ^/api/(.*)$ /$1 break;
			proxy_pass http://api/;
		} 

sso配置：

var host = window.location.protocol + "//" + window.location.hostname;
window.context = {
  manage: host + ':8080/mvue', //管理端页面
  front: host + ':8080/fvue', //前端页面
  mobile: host + ':8080/mobilevue', //手机端页面
  form: host + ':8080/api',
  portal: host + ':8080/api',
  bpmRunTime: host + ':8080/api',
  bpmModel: host + ':8080/api',
  uc: host + ':8080/api',
  mc: host + ':8080/api'
}
