How do I create an Aws::Utils::ByteBuffer from QString for AWS C++ SDK?

Jim Hankins

I'm new to C++ and QT, working with the AWS C++ SDK, the Kinesis PutRecordRequest requires a data property (the message). It takes a Aws::Utils::ByteBuffer. I'm having trouble understanding how to create this from a QString.

Hi
What is Aws::Utils::ByteBuffer ?
Seems to be
Array<unsigned char> Aws::Utils::ByteBuffer
So you could loop the string and add to such Array.

Array<unsigned char>

Yes, it appears that's what it is. Could I bother you for an example on this?

I believe I've got it.

and then

typedef Aws::Utils::Array<unsigned char> ByteBuffer;
...
Aws::String streamName = "qt";
QString myMessage = "The Message";
Aws::Kinesis::KinesisClient kinesis;
Aws::Kinesis::Model::PutRecordRequest k_req;
k_req.SetStreamName(streamName);
k_req.SetPartitionKey("123");
k_req.SetData(ByteBuffer((unsigned char *)myMessage.toStdString().c_str(),myMessage.length()));
auto k_out = kinesis.PutRecord(k_req);
...
