How can I get blockInfo by txId

[artz001]

I can't find a similar way like fabric-gateway-java :

Channel channel = network.getChannel();
channel.queryBlockByTransactionID("");

You can evaluate the GetBlockByTxID transaction function on the qscc system chaincode. The qscc system chaincode is not well documented but the implementation is here:

https://github.com/hyperledger/fabric/blob/main/core/scc/qscc/query.go

GetBlockByTxID takes two arguments: channel name and transaction ID. It returns a serialized Block protocol buffer message. You can deserialize this using the fabric-protos language bindings for the Fabric protocol buffer messages:

var block = org.hyperledger.fabric.protos.common.Block.parseFrom(responseBytes);

The off_chain_data sample demonstrates how to navigate the block structure and retrieve information. You might want to reuse some or all of the parser code from there.
