```
//! Retrieve the default settings for sending SMS messages from your AWS account by using
//! Amazon Simple Notification Service (Amazon SNS).
/*!
  \param clientConfiguration: AWS client configuration.
  \return bool: Function succeeded.
 */
bool

    //Set the request to only retrieve the DefaultSMSType setting.
    //Without the following line, GetSMSAttributes would retrieve all settings.

#### [ CLI ]

**AWS CLI**  
**列出默认 SMS 消息属性**  
以下 `get-sms-attributes` 示例将列出发送 SMS 消息的默认属性。  

```
aws sns get-sms-attributes
```
输出：  

```
{
    "attributes": {
        "DefaultSenderID": "MyName"
    }
}
```

在单独的模块中创建客户端并将其导出。  

```
import { SNSClient } from "@aws-sdk/client-sns";

// The AWS Region can be provided here using the `region` property. If you leave it blank
// the SDK will default to the region set in your AWS config.
export const snsClient = new SNSClient({});
```
导入 SDK 和客户端模块，然后调用 API。  

```
import { GetSMSAttributesCommand } from "@aws-sdk/client-sns";
import { snsClient } from "../libs/snsClient.js";

export const getSmsAttributes = async () => {
  const response = await snsClient.send(
    // If you have not modified the account-level mobile settings of SNS,
    // the DefaultSMSType is undefined. For this example, it was set to
    // Transactional.
    new GetSMSAttributesCommand({ attributes: ["DefaultSMSType"] }),
  );

  console.log(response);
  // {
  //   '$metadata': {
  //     httpStatusCode: 200,
  //     requestId: '67ad8386-4169-58f1-bdb9-debd281d48d5',
