CheckDomainAvailability与 Amazon SDK 或 CLI 配合使用

    /// <summary>
    /// Check the availability of a domain name.
    /// </summary>
    /// <param name="domain">The domain to check for availability.</param>
    /// <returns>An availability result string.</returns>
    public async Task<string> CheckDomainAvailability(string domain)
    {
        var result = await _amazonRoute53Domains.CheckDomainAvailabilityAsync(
            new CheckDomainAvailabilityRequest
            {
                DomainName = domain
            }
        );
        return result.Availability.Value;
    }

确定是否可以在 Route 53 上注册域名

以下check-domain-availability命令返回有关域名example.com是否可以使用 Route 53 注册的信息。

此命令仅在us-east-1区域中运行。如果您的默认区域设置为us-east-1，则可以省略该region参数。

aws route53domains check-domain-availability \
    --region us-east-1 \
    --domain-name example.com

输出：

{
    "Availability": "UNAVAILABLE"
}

Route 53 支持大量顶级域名 (TLD)，例如.com和.jp，但我们并不支持所有可用的顶级域名。如果您检查域名的可用性，而 Route 53 不支持该顶级域名，check-domain-availability则会返回以下消息。

An error occurred (UnsupportedTLD) when calling the CheckDomainAvailability operation: <top-level domain> tld is not supported.

有关在 Route 53 注册域名时可以使用的顶级域名列表，请参阅《亚马逊 Route 53 开发者指南》中的 “您可以在亚马逊 Route 53 上注册的域名”。有关使用亚马逊 Route 53 注册域名的更多信息，请参阅亚马逊 R oute 53 开发者指南中的注册新域名。
