How to set useVirtualAddressing=false for S3EncryptionClient

[zmw132]

Aws::Auth::AWSCredentials cred(ak, sk);

ClientConfiguration clientConfig;
clientConfig.endpointOverride = endPoint;
clientConfig.scheme = Http::Scheme::HTTP;
clientConfig.verifySSL = false;

auto encryptionMaterials = Aws::MakeSharedAws::S3Encryption::Materials::SimpleEncryptionMaterials(
"S3EncryptionClient", key);
CryptoConfiguration cryptoConfiguration(StorageMethod::METADATA, CryptoMode::ENCRYPTION_ONLY);

s3EncryptionClient = Aws::MakeSharedAws::S3Encryption::S3EncryptionClient(
"S3EncryptionClient",
encryptionMaterials,
cryptoConfiguration,
cred,
clientConfig
);

When using the above S3EncryptionClient to PutObject, an error occurred: curlCode: 6, Couldn't resolve host name， This may require setting useVirtualAddressing=false, but the implementation of the setting cannot be found. How to solve it?

clientConfig.endpointOverride = endPoint;

what is endPoint? is it resolvable? that will be used regardless if virtual addressing is used or not

but the implementation of the setting cannot be found. How to solve it?

that is on the S3ClientConfiguration configuration object which is not currently able to be passed to the encryption client. will work on exposing that.

That said this is likely not your problem however since you override the endpoint, if you override the endpoint, virtual addressing is not relevant, likely what host name are using is unresolvable.

Created a PR that should hopefully address the inability to play with S3 specific configurations

[sbiscigl]

that is now merged and you should be able to do something like this on the latest version.

#include <aws/core/Aws.h>
#include <aws/s3-encryption/S3EncryptionClient.h>

using namespace Aws;
using namespace Aws::S3Encryption;
using namespace Aws::S3;
using namespace Aws::Utils;

namespace {
const char* LOG_TAG = "test-app";
}

auto main() -> int {
  SDKOptions options{};
  options.loggingOptions.logLevel = Logging::LogLevel::Debug;
  InitAPI(options);
  {
    CryptoBuffer symmetric_key{ByteBuffer{"symmetric_key"}};
    const auto simple_materials =
        Aws::MakeShared<Materials::SimpleEncryptionMaterialsWithGCMAAD>(
            LOG_TAG, symmetric_key);
    CryptoConfigurationV2 configuration_v2{simple_materials};
    S3ClientConfiguration client_configuration{};
    client_configuration.useVirtualAddressing = false;
    S3EncryptionClientV2 client_v2{
        configuration_v2, [&client_configuration]() -> UniquePtr<S3Client> {
          return Aws::MakeUnique<S3Client>(LOG_TAG, client_configuration);
        }};
  }
  ShutdownAPI(options);
  return 0;
}

although your issue is much more likely related to the actual override not being resolvable.
