超级账本背书政策和调用链码错误（不更新账本）答案

【问题标题】：Hyperledger endorsement policy and invoking chaincode error (no updating the ledger)超级账本背书政策和调用链码错误（不更新账本）
【发布时间】：2021-07-28 20:05:07
【问题描述】：

我使用的是 Hyperledger Fabric 1.4.8

我已经使用以下命令部署了一个链代码：

peer chaincode install -n davidcodeEndorseAnd -v vAlfaBeta1 -p github.com/chaincode/chaincode_example02/go/

peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n davidcodeEndorseAnd -v vAlfaBeta1 -c '{"Args":["init","a","0","b","10000"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"

背书参数：AND ('Org1MSP.peer','Org2MSP.peer')。

当我尝试使用以下命令调用链代码时，我收到 200 响应，但值未更新：

peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C mychannel -n davidcodeEndorseAnd  -c '{"Args":["invoke","a","b","900"]}

执行输出：

root@50179e3b3e32:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n davidcodeEndorseAnd -c '{"Args":["query","a"]}'
0

root@50179e3b3e32:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C mychannel -n davidcodeEndorseAnd -c '{"Args":["invoke","b","a","900"]}'

root@50179e3b3e32:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n davidcodeEndorseAnd -c '{"Args":["query","a"]}'
0

注意：我使用的是结构样本的链码示例：/fabric-samples/chaincode/chaincode_example02/go

我尝试了以下调用命令但没有成功：

peer chaincode invoke -o orderer.example.com:7050 -C mychannel -n davidcodeEndorseAnd --peerAddresses peer0.org1.example.com:7051 --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles "/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" --tlsRootCertFiles "/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"Args":["invoke","a","b","100"]}'

执行的输出：

我已成功更新账本：

Org1下的执行输出：

root@50179e3b3e32:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n davidcodeEndorseAnd -c '{"Args":["query","a"]}'

2021-07-28 20:17:56.431 UTC [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200

90
root@50179e3b3e32:/opt/gopath/src/github.com/hyperledger/fabric/peer#

Org2 下的查询执行：

root@50179e3b3e32:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n davidcodeEndorseAnd -c '{"Args":["query","a"]}'
90

9910
root@50179e3b3e32:/opt/gopath/src/github.com/hyperledger/fabric/peer#

问题是我错过了调用命令的 orderer 的以下参数：

--cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
