export org=1export peer=0export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

查询审批结果，命令

peer lifecycle chaincode queryapproved --peerAddresses ${CORE_PEER_ADDRESS} --tlsRootCertFiles ${CORE_PEER_TLS_ROOTCERT_FILE} --channelID businesschannel --name test_chaincode --output json

返回该节点org1-peer0审批过的chancode，这里只审批了test_chaincode，所以只有chaincode

5.2、在org2-peer0上进行查询

进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org2-peer0身份

export org=2export peer=0export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

查询审批结果，命令

peer lifecycle chaincode queryapproved --peerAddresses ${CORE_PEER_ADDRESS} --tlsRootCertFiles ${CORE_PEER_TLS_ROOTCERT_FILE} --channelID businesschannel --name test_chaincode --output json

六、查询指定chaincode是否可以提交

查询意义：在chaincode安装时，经历了审批步骤如第四步，并通过属性--signature-policy指定背书策略，所以指定chaincode需要满足了指定的背书策略，才可以提交并使用

6.1、在org1-peer0上查询

进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org1-peer0身份

export org=1export peer=0export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

查询审批结果，命令

peer lifecycle chaincode checkcommitreadiness --channelID businesschannel --name test_chaincode --version 1.0 --output json --sequence 1

七、向通道提交链码

提交可以在一个peer上完成，这里使用org1-peer0进行操作
进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org1-peer0身份

export org=1export peer=0export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

使用org1-per0以及org2-peer0的证书，将chaincode提交到这两个节点上，命令

# 开启tlspeer lifecycle chaincode commit -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode --version 1.0 --init-required --sequence 1 \--peerAddresses peer0.org1.example.com:7051 \--tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \--peerAddresses peer0.org2.example.com:7051 \--tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \--waitForEvent \--signature-policy "OR ('Org1MSP.member','Org2MSP.member')" \--tls true \--cafile /etc/hyperledger/fabric/crypto-config/ordererOrganizations/example.com/orderers/orderer0.example.com/tls/ca.crt# 未开启tlspeer lifecycle chaincode commit -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode --version 1.0 --init-required --sequence 1 \--peerAddresses peer0.org1.example.com:7051 \--tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \--peerAddresses peer0.org2.example.com:7051 \--tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \--waitForEvent \--signature-policy "OR ('Org1MSP.member','Org2MSP.member')"

八、查询指定通道上已经提交的链码

这里使用org1-peer0的身份进行查询，因为channel在org1与org2之间，所以用一个节点查询即可
进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org1-peer0身份

export org=1export peer=0export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

查询命令

peer lifecycle chaincode querycommitted --channelID businesschannel --output json

可以看到chaincode_definitions属性里的数组只有一个值：test_chaincode

九、操作链码进行初始化以及转账和查询操作 9.1、在org1-peer0上进行初始化操作

进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org1-peer0身份

export org=1export peer=0export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

初始化操作，命令

#开启tlspeer chaincode invoke -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode --peerAddresses ${CORE_PEER_ADDRESS} --tlsRootCertFiles ${CORE_PEER_TLS_ROOTCERT_FILE} --isInit -c '{"Args":["init","a","100","b","200"]}' --tls --cafile /etc/hyperledger/fabric/crypto-config/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem#未开启tlspeer chaincode invoke -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode --peerAddresses ${CORE_PEER_ADDRESS} --tlsRootCertFiles ${CORE_PEER_TLS_ROOTCERT_FILE} --isInit -c '{"Args":["init","a","100","b","200"]}'

9.2、在org1-peer1上进行初始状态查询操作

进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org1-peer1身份

export org=1export peer=1export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

初始状态查询操作，命令

peer chaincode query -C businesschannel -n test_chaincode -c '{"Args":["query","a"]}' 9.3、在org2-peer0上进行转账操作

进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org2-peer0身份

export org=2export peer=0export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

转账操作，命令

#开启tlspeer chaincode invoke -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode -c '{"Args":["invoke","a","b","10"]}' --tls --cafile /etc/hyperledger/fabric/crypto-config/ordererOrganizations/example.com/orderers/orderer0.example.com/tls/ca.crt#未开启tlspeer chaincode invoke -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode -c '{"Args":["invoke","a","b","10"]}'

9.2、在org2-peer1上进行转账后状态查询操作

进入cli容器，命令：docker exec -it fabric-cli /bin/bash
进入容器的tmp目录，命令：cd /tmp
设置环境变量，使用org2-peer1身份

export org=2export peer=1export CORE_PEER_LOCALMSPID=Org${org}MSPexport CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/mspexport CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt

状态查询操作，命令

【实验第七节——用户chaincode相关操作】

#查询a账户peer chaincode query -C businesschannel -n test_chaincode -c '{"Args":["query","a"]}'#查询b账户peer chaincode query -C businesschannel -n test_chaincode -c '{"Args":["query","b"]}'
