Alicloud Network Dns Cli Test

This is a minimal test harness for Alibaba Cloud's DNS service through the aliyun CLI. It runs a simple DescribeSubDomainRecords command to verify your AK/SK credentials are working and that you can query DNS records for a given domain and subdomain. The skill is written in Chinese with basic test steps: it logs request IDs and record counts, and if nothing comes back, it runs the query again to confirm the empty result. It's bare bones validation, not a full featured DNS management tool. Useful if you're setting up alicloud credentials for the first time or debugging why DNS queries aren't working, but you'll need the aliyun CLI already installed and configured.
