Question

在使用AWS C ++ SDK时，我遇到了一个问题，即在上传超过400KB时，尝试执行PutObjectRequest会抱怨它“无法连接到端点”。

Aws::Client::ClientConfiguration clientConfig;
clientConfig.scheme = Aws::Http::Scheme::HTTPS;
clientConfig.region = Aws::Region::US_EAST_1;

Aws::S3::S3Client s3Client(clientConfig);

Aws::S3::Model::PutObjectRequest putObjectRequest;
putObjectRequest.SetBucket("mybucket");
putObjectRequest.SetKey("mykey");

typedef boost::iostreams::basic_array_source<char> Device;
boost::iostreams::stream_buffer<Device> stmbuf(compressedData, dataSize);
std::iostream *stm = new std::iostream(&stmbuf);

putObjectRequest.SetBody(std::shared_ptr<Aws::IOStream>(stm));
putObjectRequest.SetContentLength(dataSize);

Aws::S3::Model::PutObjectOutcome outcome = s3Client.PutObject(putObjectRequest);

只要我的数据小于~400KB，就会将其上传到S3上的文件中，但除此之外，它无法连接到端点。我应该能够在一个PutObjectRequest中上传最多5GB。

有什么想法吗？

响应@ JonathanHenson的评论，AWS日志反复显示此超时错误：

Answer 1

最终解决这个问题的是设置请求超时。请求超时需要足够长，以便完成整个传输。如果要在慢速Internet连接上传输大文件，请确保请求超时足够长，以允许传输这些文件。

Aws::Client::ClientConfiguration clientConfig;
clientConfig.scheme = Aws::Http::Scheme::HTTPS;
clientConfig.region = Aws::Region::US_EAST_1;
clientConfig.connectTimeoutMs = 30000;
clientConfig.requestTimoutMs = 600000;

将您的配置文件调整到下面。看到它会起作用。

Aws::Client::ClientConfiguration clientConfig;
clientConfig.scheme = Aws::Http::Scheme::HTTPS;
clientConfig.region = Aws::Region::US_EAST_1;
clientConfig.connectTimeoutMs = 30000;

Aws::S3::S3Client s3Client(clientConfig);

Aws::S3::Model::PutObjectRequest putObjectRequest;
putObjectRequest.SetBucket("mybucket");
putObjectRequest.SetKey("mykey");

typedef boost::iostreams::basic_array_source<char> Device;
boost::iostreams::stream_buffer<Device> stmbuf(compressedData, dataSize);
std::iostream *stm = new std::iostream(&stmbuf);

putObjectRequest.SetBody(std::shared_ptr<Aws::IOStream>(stm));
putObjectRequest.SetContentLength(dataSize);

Aws::S3::Model::PutObjectOutcome outcome = s3Client.PutObject(putObjectRequest);

AWS C ++ S3 SDK PutObjectRequest无法连接到端点
