贴一个可以用的nginx配置，配合该PR打包：

server {
  listen 80;
  server_name life.a.b;
  root /var/www/life;
  location =/ {
    rewrite ^(.*)$  http://life.a.b/view/index.html;
  }
  location / {
     index view/index.html; 
     proxy_http_version 1.1;
     proxy_set_header Host $host;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header X-Forwarded-Proto $scheme;   
  }
}
