hostname <string>
callback <Function>
- err <Error>
- records 对象数组

使用 DNS 协议解析 hostname 的 CAA 记录。传递给 callback 函数的 addresses 参数将包含 hostname 可用的证书颁发机构授权记录数组（例如 [{critical: 0, iodef: 'mailto:pki@example.com'}, {critical: 128, issue: 'pki.example.com'}]）。

【Uses the DNS protocol to resolve CAA records for the hostname. The addresses argument passed to the callback function will contain an array of certification authority authorization records available for the hostname (e.g. [{critical: 0, iodef: 'mailto:pki@example.com'}, {critical: 128, issue: 'pki.example.com'}]).】
