老师 我也遇到了同样的问题：
axios请求书本详情页和搜索书籍，在本地可以正常访问到数据。但是部署到自己的服务器后报错如下：
0|app | Error: getaddrinfo ENOTFOUND t.yushu.im
0|app | at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:64：26）
是不是服务器上的HTTPS配置问题：
upstream app_weapp {
server localhost:3000;
keepalive 8;
}
server {
listen 80;
server_name mi.com;
rewrite ^(.*)$ https://$server_name$1 permanent;
}
server {
listen 443 ssl;
server_name mi.com;
ssl_certificate /data/release/nginx/3493452.pem;
ssl_certificate_key /data/release/nginx/3493452.key;

}
