OSS怎么使用内网地址？

ECS和OSS地址都是使用的华东1区的；OSS默认的是外网地址，上传一个图片后，用外网链接可以访问https://xswwzcy.oss-cn-hangzhou.aliyuncs.com/pgsjzqbj.gif 

换成内网链接无法访问https://xswwzcy.oss.cn-hangzhou-intemal.aliyuns.com/pgsjzqbj.gif

域名解析地址是 CNAME记录xswwzcy.oss-cn-hangzhou.aliyuncs.com

nginx配置是server {

        listen       80;
        root /www/web/tu_xingshengsz_com/public_html;
