与 AWS SDK DescribeDomain 配合使用
以下代码示例演示了如何使用 DescribeDomain。
操作示例是大型程序的代码摘录，必须在上下文中运行。在以下代码示例中，您可以查看此操作的上下文：
- Java
-
- 适用于 Java 的 SDK 2.x
-
/**
* Describes the specified domain asynchronously.
*
* @param domainName the name of the domain to describe
* @return a {@link CompletableFuture} that completes with the ARN of the domain
* @throws RuntimeException if the domain description fails
*/
public CompletableFuture<String> describeDomainAsync(String domainName) {
DescribeDomainRequest request = DescribeDomainRequest.builder()
.domainName(domainName)
.build();
return getAsyncClient().describeDomain(request)
.handle((response, exception) -> { // Handle both response and exception
if (exception != null) {
throw new RuntimeException("Failed to describe domain", exception);
}
DomainStatus domainStatus = response.domainStatus();
String endpoint = domainStatus.endpoint();
String arn = domainStatus.arn();
String engineVersion = domainStatus.engineVersion();
logger.info("Domain endpoint is: " + endpoint);
logger.info("ARN: " + arn);
System.out.println("Engine version: " + engineVersion);
return arn; // Return ARN when successful
});
}
