问题描述
我正在将kcl v1.13.3与最新的localstack v0.11.5一起使用 现在，kcl客户端使用边缘服务端口4566。
kcl和localstack版本兼容吗？
我一直收到以下错误：
com.amazonaws.SdkClientException：无法执行HTTP请求：目标服务器无法响应
由以下原因引起：org.apache.http.NoHttpResponseException：目标服务器无法响应

解决方法
您是否已确认localstack端点在该端口上正常工作？例如：
aws kinesis list-streams --endpoint http://localhost:4566
（如果您尚未安装并希望安装aws cli，则始终可以选择使用docker）
此外，分享您如何增强AWS客户端的方式可能对您有所帮助。应该是这样的：
AwsClientBuilder.EndpointConfiguration endpointConfig = new AwsClientBuilder.EndpointConfiguration("http://localhost:4566",Regions.EU_WEST_1.getName());
return AmazonDynamoDBClientBuilder.standard()
.withEndpointConfiguration(endpointConfig)
.build();
请注意，如果您在另一个Docker容器中运行kcl应用程序，则可能需要从“ http：// localhost：4566”更改为“ http：// localstack：4566”。
