amazon s3 - AWS C++ S3 SDK PutObjectRequest unable to connect to endpoint

在使用AWS C++SDK时，我遇到了一个问题，在尝试执行PutObjectRequest时，当上传超过约400KB时，它会抱怨"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，它就会被上传到S3上的一个文件中，但超过这个范围，它就无法连接到端点。我应该能够在一个PutObjectRequest中上传高达5GB的内容。

有什么想法吗？

最终解决这个问题的是设置请求超时。请求超时时间需要足够长，以便完成整个传输。如果您在慢速互联网连接上传输大文件，请确保请求超时时间足够长，可以传输这些文件。

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。看看它会起作用。

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);
