使用超级账本结构 2.0 提交链代码调用/查询时出错

Question

我已经使用命令成功提交了链码：

./peer lifecycle chaincode commit -o orderer.example.org:7050 --channelID mychannel --name emp_chaincode --version v1 --sequence 1 --init-required --tls --cafile ./crypto-config/ordererOrganizations/example.org/orderers/orderer.example.org/msp/tlscacerts/tlsca.example.org-cert.pem

现在，当我尝试调用/查询链码时，出现此错误：

Error: endorsement failure during invoke. response: status:500 message:"error in simulation: failed to execute transaction f490a9e7bca41ad10f68306decae2fdd73e09a9d5f81da7c9ee5cdc3811b3f27: invalid invocation: chaincode 'emp_chaincode' has not been initialized for this version, must call as init first"

在链码容器日志中，它显示：

+ CHAINCODE_DIR=/usr/local/src

+ cd /usr/local/src

+ npm start -- --peer.address peer0.org1.example.org:7052


> employee@1.0.0 start /usr/local/src

> node emp_chaincode.js "--peer.address" "peer0.org1.example.org:7052"

请让我知道我该如何解决它。

更新：

在 R Thatcher 建议添加标志之后，我现在得到的错误是：

Error: endorsement failure during invoke. response: status:500 message:"error in simulation: failed to execute transaction 038b5c303dfdd98db2c2fc0d2eac6146d7221691cbbed7a78227f5a76a31a240: could not launch chaincode emp_chaincodev1:5bcbed31afc58894912eb4c66d63adcec7eab029e2b911887412b119ef5cf319: chaincode registration failed: container exited with 0"

Answer 1

在错误结束时，您必须首先调用 init。

我认为您已经使用了peer chaincode lifecycle approveformyorg带有 flag 的命令--init-required。这意味着新链码的第一次调用必须使用--isInit标志 例如peer chaincode invoke -C tradechannel -n trade --isInit ...。在第一个“特殊”调用之后，其他调用和查询就可以了。
