#### [ CLI ]

**AWS CLI**  
**请求新的 ACM 证书**  
以下 `request-certificate` 命令使用 DNS 验证为 www.example.com 域请求新证书：  

```
aws acm request-certificate --domain-name www.example.com --validation-method DNS
```
您可以输入幂等性令牌，以区分对 `request-certificate` 的调用：  

```
aws acm request-certificate --domain-name www.example.com --validation-method DNS --idempotency-token 91adc45q
```
您可以输入一个或多个主题备用名称来请求能够保护多个顶级域的证书：  

```
aws acm request-certificate --domain-name example.com --validation-method DNS --idempotency-token 91adc45q --subject-alternative-names www.example.net
```
您可以输入一个备用名称，该名称也可用于访问您的网站：  

```
aws acm request-certificate --domain-name example.com --validation-method DNS --idempotency-token 91adc45q --subject-alternative-names www.example.com
```
您可以使用星号（\$1）作为通配符为同一域中的多个子域创建证书：  

```
aws acm request-certificate --domain-name example.com --validation-method DNS --idempotency-token 91adc45q --subject-alternative-names *.example.com
```
您也可以输入多个备用名称：  

```
aws acm request-certificate --domain-name example.com --validation-method DNS --subject-alternative-names b.example.com c.example.com d.example.com
```
如果您使用电子邮件进行验证，则可以输入域验证选项来指定将验证电子邮件发送到的域：  

```
aws acm request-certificate --domain-name example.com --validation-method EMAIL --subject-alternative-names www.example.com --domain-validation-options DomainName=example.com,ValidationDomain=example.com
```
以下命令会在您请求新证书时选择退出证书透明度日志：  

```
aws acm request-certificate --domain-name www.example.com --validation-method DNS --options CertificateTransparencyLoggingPreference=DISABLED --idempotency-token 184627
```
