使用AWS-SDK-CPP时出现“ MalformedXML”错误

Question

我正在第一次尝试将文件上传到s3存储桶：

#include <iostream>
#include <aws/core/Aws.h>
#include <aws/s3/S3Client.h>
#include <aws/s3/model/PutObjectRequest.h>
#include <aws/core/auth/AWSCredentialsProvider.h>

#include <iostream>
#include <fstream>
#include <sys/stat.h>

#include <curl/curl.h>

using namespace Aws::Auth;
using namespace Aws::Http;
using namespace Aws::Client;
using namespace Aws::S3;
using namespace Aws::S3::Model;
using namespace Aws::Utils;    

int main(int argc, const char * argv[]) {

    Aws::SDKOptions options;
    Aws::InitAPI(options);

    ClientConfiguration clientConfig;
    //config.region = "us-west-2";
    clientConfig.scheme = Aws::Http::Scheme::HTTPS;
    clientConfig.region = Aws::Region::US_EAST_2;
    clientConfig.connectTimeoutMs = 30000;
    clientConfig.requestTimeoutMs = 600000;
    clientConfig.enableHostPrefixInjection = true;

    static const char * ACCESS_KEY_ID = "myKey";      
    static const char * SECRET_KEY = "mySecretKey";
    static const char * ALLOCATION_TAG = "SampleAllocationTag";

    static const char * filename = "myFilename";

    std::shared_ptr<S3Client> client = Aws::MakeShared<S3Client>(
                                                                 ALLOCATION_TAG,
                                                                 AWSCredentials(Aws::String(ACCESS_KEY_ID), Aws::String(SECRET_KEY)),
                                                                                clientConfig
                                                                                );

    Aws::S3::Model::PutObjectRequest object_request;

    object_request.SetBucket("myBucketName");
    //object_request.SetKey(s3_object_name);
    const std::shared_ptr<Aws::IOStream> input_data =
    Aws::MakeShared<Aws::FStream>(ALLOCATION_TAG,
                                  filename,
                                  std::ios_base::in | std::ios_base::binary);
    object_request.SetBody(input_data);

    // Put the object
    auto put_object_outcome = client->PutObject(object_request);
    if (!put_object_outcome.IsSuccess()) {
        auto error = put_object_outcome.GetError();
        std::cout << "ERROR: " << error.GetExceptionName() << ": "
        << error.GetMessage() << std::endl;
    }

    Aws::ShutdownAPI(options);

    return 0;
}

我遇到以下错误：

  

错误：MalformedXML：无法解析ExceptionName：MalformedXML消息：您提供的XML格式不正确或未针对我们发布的架构进行验证

这是什么意思以及如何解决？
