使用節點SDK在Hyperledger Fabric上升級Chaincode

Question

我正在嘗試使用hyperledger架構中的node-sdk安裝和升級chaincode。 但是我似乎丟失了一些東西。

我可以在對等節點上正確安裝鏈碼，但是無法升級它。 我缺少某種transactionId

基本上，我想使用sdk來執行以下操作：

peer chaincode install -n mychaincode -p /path/to/chaincode -l node -v 0.0.2

peer chaincode upgrade -C mychannel -n mychaincode -l node -v 0.0.2 -c '{"Args": ["instantiate", "test"]}'

使用SDK：

// Create a new gateway for connecting to our peer node.
const gateway = new Gateway();
await gateway.connect(ccp, { wallet, identity: 'xxxx' });

const client = gateway.getClient();
const peers = client.getPeersForOrg('PeerMSP');

let installResponse = await client.installChaincode({
    targets: peers,
    chaincodePath: '/path/to/chaincode',
    chaincodeId: 'mychaincode',
    chaincodeVersion: '0.0.2',
    chaincodeType: 'node',
    channelNames: ['mychannel']
});

let channel = client.getChannel('mychannel');

let upgradeResponnse = await channel.sendUpgradeProposal({
    targets: peers,
    chaincodeType: 'node',
    chaincodeId: 'mychaincode',
    chaincodeVersion: '0.0.2',
    args: ['instantiate', 'test'],
    txId: ??????? <----------------------------------
});

我想念什么？

為了將來參考，我缺少了client.newTransactionID() 。

完整的例子

// Create a new gateway for connecting to our peer node.
const gateway = new Gateway();
await gateway.connect(ccp, { wallet, identity: 'xxxx' });

const client = gateway.getClient();
const peers = client.getPeersForOrg('PeerMSP');

let installResponse = await client.installChaincode({
    targets: peers,
    chaincodePath: '/path/to/chaincode',
    chaincodeId: 'chaincode',
    chaincodeVersion: '0.0.2',
    chaincodeType: 'node',
    channelNames: ['mychannel']
});

let channel = client.getChannel('mychannel');

let proposalResponse = await channel.sendUpgradeProposal({
    targets: peers,
    chaincodeType: 'node',
    chaincodeId: 'chaincode',
    chaincodeVersion: '0.0.2',
    args: ['test'],
    fcn: 'instantiate',
    txId: client.newTransactionID()
});

console.log(proposalResponse);

console.log('Sending the Transaction ..');
const transactionResponse = await channel.sendTransaction({
    proposalResponses: proposalResponse[0],
    proposal: proposalResponse[1]
});

console.log(transactionResponse);

每當升級鏈碼時，都需要更改其版本。 我看到您對兩個命令都使用了相同的版本0.0.2 。 請更改並檢查。

對等鏈代碼升級-o orderer.example.com:7050 --tls --cafile $ ORDERER_CA -C mychannel -n mycc -v 0.0.3 -c'{“ Args”：[“ init”，“ a”，“ 100 “，” b“，” 200“，” c“，” 300“]}'-P” AND（'Org1MSP.peer'，'Org2MSP.peer'）“
