This has happened in aws-sdk-java, maybe it is missed in v2?这在 aws-sdk-java 中已经发生，也许它在 v2 中被遗漏了？ aws/aws-sdk-java#1018 aws/aws-sdk-java#1018

If you are using Okhttp as client, you can add a custom header configuration: Accept-Encoding: gzip如果您使用 Okhttp 作为客户端，您可以添加自定义 header 配置：Accept-Encoding: gzip
You can do something like this in kotlin:你可以在 kotlin 中做这样的事情：
val httpClient: HttpHandler = OkHttp()
val awsHttpClient = AwsSdkClient(httpClient)
val dynamoDbClient: DynamoDbClient =
DynamoDbClient.builder()
.region(Region.of(environment.getAwsRegion()))
.httpClient(awsHttpClient)
.overrideConfiguration { o -> o.putHeader("Accept-Encoding", "gzip") }
.build()
val enhancedClient: DynamoDbEnhancedClient =
DynamoDbEnhancedClient.builder()
.dynamoDbClient(dynamoDbClient)
.build()
val tableName = ...
val schema = ...
val table = enhancedClient.table(tableName, schema)
val key = ..
table.getItem(key)

I have not seen others use OkHttp for their AWS clients before, and I believe that this HTTP client uses gzip compression by default.我之前没有看到其他人为他们的 AWS 客户端使用 OkHttp，我相信这个 HTTP 客户端默认使用 gzip 压缩。 To change the configuration you would need to write a.network interceptor as described here .要更改配置，您需要按照此处所述编写一个.network 拦截器。
I suggest first building with the default HTTP client, which just requires you to remove 2 lines of code.我建议首先使用默认的 HTTP 客户端进行构建，这只需要您删除 2 行代码。 That will allow you to understand if OkHTTP is in fact the issue.这将使您了解 OkHTTP 是否确实是问题所在。
