window.open打开本地nginx部署项目路由报错404？

Question

nginx 配置
server {
        listen 90;
        server_name localhost; # 服务器域名或 IP 地址
        location / {
                root   D:/nginx-1.24.0/html/dist;
                index  index.html index.htm projectb.html;
            }
    }

vue 路由配置

const routes = [
  {
    path: '/',
    name: 'Index',
    component: Index,
  },
  {
     path: '/scanCodeScreen',
    name: 'scanCodeScreen',
     component: scanCodeScreen,
  },
  {
    path: '/IndexOld',
    name: 'IndexOld',
    component: IndexOld,
  },
]

const router = new VueRouter({
  mode: 'history', //去掉url中的#
  base: '/',
  routes,
})

export default router

window.open('http://localhost:90/scanCodeScreen', '_blank'); 报错404
