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

Question

在使用 AWS C++ SDK 时，我运行遇到一个问题，在尝试执行 PutObjectRequest 时，上传超过 ~400KB 时抱怨它是 "unable to connect to endpoint"。

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，它就会被上传到 S3 上的一个文件中，但超过该文件就无法连接到端点。我应该能够在一个 PutObjectRequest 中上传最多 5GB。

有什么想法吗？

回应@JonathanHenson 的评论，AWS 日志反复显示此超时错误：

将您的配置文件调整为 below.And 看看它是否会起作用。

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);

最终为我解决此问题的是设置请求超时。请求超时需要足够长才能完成整个传输。如果您在较慢的 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;
