将文件上传到S3 AWS SDK CPP时出错

Question

所以我试图使用aws sdk cpp将本地文件上传到aws s3。 这是我从问题here

中获取的示例代码

#include <aws/core/Aws.h>
#include <aws/s3/S3Client.h>
#include <aws/core/utils/HashingUtils.h>
#include <aws/s3/model/PutObjectRequest.h>
#include <iostream>
#include <fstream>

using namespace Aws::S3::Model;
using namespace std;
using namespace Aws::Utils;

 static const char* KEY = "try.txt";
 static const char* BUCKET = "bucket-name";

 int main()
 {
Aws::SDKOptions options;
Aws::InitAPI(options);

Aws::Client::ClientConfiguration myConf;
myConf.region = Aws::Region::US_EAST_2;
Aws::S3::S3Client s3_client(myConf);

const Aws::String bucket_name = BUCKET;
const Aws::String key_name = KEY;
const Aws::String dir_name = "C:/Users/linda.naoui/source/repos/Upload s3";

std::cout << "Uploading " << key_name << " to S3 bucket: " <<
    bucket_name << std::endl;



Aws::S3::Model::PutObjectRequest object_request;
object_request.WithBucket(bucket_name).WithKey(key_name);

auto input_data = Aws::MakeShared<Aws::FStream>(key_name.c_str(), dir_name.c_str(), std::ios_base::in);

object_request.SetBody(input_data);

auto put_object_outcome = s3_client.PutObject(object_request);

if (put_object_outcome.IsSuccess()) {
    std::cout << "Done!" << std::endl;
}
else {
    std::cout << "PutObject error: " <<
        put_object_outcome.GetError().GetExceptionName() << " " <<
        put_object_outcome.GetError().GetMessage() << std::endl;
}

Aws::ShutdownAPI(options);

return 0;
  }

我有很多与dll导入相关的类似错误，我使用Nuget软件包安装了aws s3 sdk和aws sdk核心，我目前在Visual Studio 2019中。

我不确定问题是否在于链接窗口为空

我通过卸载Visual Studio 2019并改用Visual Studio 2017解决了该问题
