自动域控制验证 (DCV) 检查（也称为 DCV 轮询）意味着您在使用 DNS TXT、DNS CNAME 和 HTTP 实用演示/文件 DCV 方法时，无需自行进行验证检查。
将 fileauth.txt 文件放置在域上或在 DNS TXT 或 DNS CNAME 记录中添加随机值后，您无需登录 CertCentral 自行进行检查。我们将自动运行 DCV 检查。但是，如有需要，您仍然可以手动进行检查。
提交公共 SSL/TLS 证书订单、提交域进行预验证或更改域的 DCV 方法后，将立即启动 DCV 轮询并运行一周。
*间隔 5 结束后停止检查。如果在第一周结束后还未将 fileauth.txt 文件放置在域上或在 DNS TXT 或 DNS CNAME 记录中添加随机值，则需要您自行进行检查。
