如何从 EC2 实例内部（即连接后）查看分配给 EC2 实例的公共 IP 地址？我可以看到分配给它的公共 IP 地址，只需在管理控制台中查看即可。
从AWS 文档中，我们可以使用以下 curl 命令获取公共 IP 地址。
$ TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` && curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/meta-data
但看起来它不起作用。
$ TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` && curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/meta-data

知道如何在 EC2 实例中获取公共 IP 吗？
