配置钉钉机器人时，我发现服务器连接oapi.dingtalk.com接口连接不上去报错如下

java.net.UnknownHostException: oapi.dingtalk.com

原因是 调用钉钉服务很慢，偶尔会报java.net.UnknownHostException: oapi.dingtalk.com
ping 一下 oapi.dingtalk.com
得到IP地址 106.11.43.160

[root@k8s-master01 ~]# ping oapi.dingtalk.com

把 106.11.43.160 oapi.dingtalk.com 配置到hosts里面

vim /etc/hosts
106.11.43.160 oapi.dingtalk.com
