c++ - 使用 C++ SDK 将文件上传到 AWS

Question

每当我运行我的程序时，我都会收到错误“无法连接到端点”。但我知道我可以连接到该存储桶，因为我可以使用相同的配置和 s3Client 成功下载该存储桶中的文件。它卡在 PutObject() 行上。

这是代码。

const String KEY = "test2.txt";
const String BUCKET = "savefiles2017";


const String fileName = "test2.txt";

Client::ClientConfiguration config;
config.region = Region::US_WEST_2;
config.scheme = Http::Scheme::HTTPS;

S3Client s3Client(Auth::AWSCredentials("XXXXXX", "YYYYYY"), config); 

//putting something into s3
PutObjectRequest putObjectRequest;
putObjectRequest.WithBucket(BUCKET).WithKey(KEY);

auto requestStream = MakeShared<FStream>("PutObjectInputStream", fileName.c_str(), ios_base::in);

putObjectRequest.SetBody(requestStream);

auto putObjectOutcome = s3Client.PutObject(putObjectRequest);

if (putObjectOutcome.IsSuccess())
{
    cout << "Put object succeeded" << endl;
}
else
{
    cout << "Error while putting Object " << putObjectOutcome.GetError().GetExceptionName() <<
        " " << putObjectOutcome.GetError().GetMessage() << endl;
}

这些也是我正在使用的包含

#include <string>
#include <iostream>
#include <fstream>
using namespace std;
#include <aws/core/Aws.h>
#include <aws/core/auth/AWSCredentialsProvider.h>
#include <aws/s3/S3Client.h>
#include <aws/s3/model/PutObjectRequest.h>
#include <aws/s3/model/GetObjectRequest.h>
#include <aws/core/utils/memory/stl/AWSStringStream.h> 


using namespace Aws;
using namespace Aws::S3;
using namespace Aws::S3::Model;

如有任何帮助，我们将不胜感激。

我想出了解决办法。我不得不换行

auto requestStream = MakeShared<FStream>("PutObjectInputStream", fileName.c_str(), ios_base::in);

到

auto requestStream = MakeShared<FStream>("PutObjectInputStream", fileName.c_str(), ios_base::in | ios_base::binary);

所以我只需要添加 ios_base::binary 的额外标志
