DescribeEndpoint 搭配 AWS SDK 或 CLI 使用

//! Describe the endpoint specific to the AWS account making the call.
/*!
  \param endpointResult: String to receive the endpoint result.
  \param clientConfiguration: AWS client configuration.
  \return bool: Function succeeded.
 */

範例 1：取得您目前的 AWS 端點

下列describe-endpoint範例會擷取套用所有命令的預設 AWS 端點。

aws iot describe-endpoint

輸出：

{
    "endpointAddress": "abc123defghijk.iot.us-west-2.amazonaws.com"
}

如需詳細資訊，請參閱 AWS IoT 開發人員指南中的 DescribeEndpoint。

範例 2：取得您的 ATS 端點

下列describe-endpoint範例會擷取 Amazon Trust Services (ATS) 端點。

aws iot describe-endpoint \
    --endpoint-type iot:Data-ATS

輸出：

{
    "endpointAddress": "abc123defghijk-ats.iot.us-west-2.amazonaws.com"
}
