# `GetBasePathMapping` 搭配 AWS SDK 或 CLI 使用
<a name="api-gateway_example_api-gateway_GetBasePathMapping_section"></a>

下列程式碼範例示範如何使用 `GetBasePathMapping`。

------
#### [ CLI ]

**AWS CLI**  
**取得自訂網域名稱的基本路徑映射**  
命令：  

```
aws apigateway get-base-path-mapping --domain-name subdomain.domain.tld --base-path v1
```
輸出：  

```
{
    "basePath": "v1",
    "restApiId": "1234w4321e",
    "stage": "api"
}
```
+  如需 API 詳細資訊，請參閱《AWS CLI 命令參考》**中的 [GetBasePathMapping](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/apigateway/get-base-path-mapping.html)。

#### [ PHP ]

**適用於 PHP 的 SDK**  
 GitHub 上提供更多範例。尋找完整範例，並了解如何在 [AWS 程式碼範例儲存庫](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/php/example_code/apigateway#code-examples)中設定和執行。

```

use Aws\Exception\AwsException;


/* ////////////////////////////////////////////////////////////////////////////
 * Purpose: Gets the base path mapping for a custom domain name in
 * Amazon API Gateway.
 *
 * Prerequisites: A custom domain name in API Gateway. For more information,
 * see "Custom Domain Names" in the Amazon API Gateway Developer Guide.
 *
 * Inputs:
 * - $apiGatewayClient: An initialized AWS SDK for PHP API client for
 *   API Gateway.
 * - $basePath: The base path name that callers must provide as part of the
 *   URL after the domain name.
 * - $domainName: The custom domain name for the base path mapping.
 *
 * Returns: The base path mapping, if available; otherwise, the error message.

        ]);
        return 'The base path mapping\'s effective URI is: ' .
            $result['@metadata']['effectiveUri'];
    } catch (AwsException $e) {
        return 'Error: ' . $e['message'];

    ]);

    echo getBasePathMapping($apiGatewayClient, '(none)', 'example.com');
}

// Uncomment the following line to run this code in an AWS account.
// getsTheBasePathMapping();
