问题出在nginx反向代理配置，大部分nginx反向代理配置如下：

server{
    listen              80;
    server_name         www.aa.com www.bb.com;
    location / {
        proxy_pass http://localhost:8080;

          proxy_set_header Host $host; 
          proxy_set_header X-Forwarded-Proto $scheme;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header Upgrade-Insecure-Requests 1;
          proxy_set_header X-Forwarded-Proto https;
    }
}

把location / {改成location ~ .* {就可以了。
