我目前正在迁移Java代码库以使用S3 client v2 instead of old v1 client。
我正在通过Minio网关与S3 API进行交互，该网关向GCS（Google云存储）发送/获取对象。
同步客户端以前可以正常工作，但是现在我无法执行简单的Put操作，例如PutObjectRequest，因为sdk客户端在实际接收到编码不同的哈希值时，会在“ eTag”字段中期望MD5哈希值。我声明我的客户如下：
AwsBasicCredentials credentials = AwsBasicCredentials.create(config.getKey(), config.getSecret());
return S3Client.builder()
.endpointOverride(URI.create(config.getEndpoint()))
.region(Region.of(config.getRegion()))
.credentialsProvider(StaticCredentialsProvider.create(credentials))
.serviceConfiguration(S3Configuration.builder().pathStyleAccessEnabled(true).build())
.build();
并将其与简单的Put请求一起使用，例如：
byte[] content = "THIS IS THE CONTENT".getBytes();
RequestBody requestBody = RequestBody.fromBytes(content);
PutObjectRequest build = PutObjectRequest.builder()
.bucket(BUCKET)
.key("test-file")
.build();
s3Client.putObject(build, requestBody);
错误堆栈跟踪如下：

一些注意事项：
Aws4Signer或AwsS3V4Signer之一添加到我的客户端配置中，但没有成功环境：
