Hyperledger Fabric: Get Block Data for all blocks

Question

I just set up a Hyperledger Fabric.network (2.2) with chaincode(node.js) for me and my team.

We are using Hyperledger SDK for NodeJS (Version 2.2) for.network interaction.

Now the problem is, we need to query block data for all transactions in the.network.

How can we get all existing blocks and query them?

With SDK 1.4, there was channel.getBlockbyTXid().

Is there a solution for the newest SDK Version?

Answer 1

Use the QSCC Chaincode and invoke functions like GetBlockByNumber and GetTransactionByID .

Example

      const network = await gateway.getNetwork("mychannel");
      const contract = network.getContract("qscc");

      let result = await contract.evaluateTransaction("GetBlockByNumber", channelName, blkNum);
      // or
      let result = await contract.evaluateTransaction("GetTransactionByID", channelName, txId);
