I used to set up a Fabric network and deployed a fabric network and basic application using a Fabric and Fabric node SDK. I'm able to do the query and write to the chain. Is there any way to retrieve the Block Info? Like block height and transactionID?

推荐答案

在具有节点sdk的Hyperledger Fabric中，您可以使用queryBlock方法

In Hyperledger Fabric with node sdk you can retrieve the block info with the queryBlock method https://hyperledger.github.io/fabric-sdk-node/release-1.4/Channel.html#queryBlock

您可以将其用作 let response_payload =等待channel.queryBlock(parseInt(blockNumber，peer)); 这将返回块的详细信息.

you can use it as let response_payload = await channel.queryBlock(parseInt(blockNumber, peer)); this will return the block details.
