使用视频博主在gitee提交的小猫的智能合约

主要功能：新建一只小猫，更新小猫信息，删除一只猫，查看小猫

预备工作

首先进入到在虚拟机中进入test-network目录

cd go/src/gihub.com/hyperledger/fabric/fabric-samples/test-network

启动测试网络

./network.sh up

创建通道

./network.sh createChannel

另开一个终端到fabric/fabric-samples/chaincode，在此目录克隆gitee上的合约

git clone https://gitee.com/kernelHP/hyperledger-fabric-contract-java-demo.git

返回到test-network所在目录，以便将链码与其他网络部件打包在一起

cd test-network

将bin目录中的二进制文件添加到CLI路径

export PATH=${PWD}/../bin:$PATH

设置FABRIC_CFG_PATH指向存储库中的core.yaml文件

export FABRIC_CFG_PATH=$PWD/../config/

创建链码包

peer lifecycle chaincode package hyperledger-fabric-contract-java-demo.tar.gz --path ../chaincode/hyperledger-fabric-contract-java-demo/ --lang java --label hyperledger-fabric-contract-java-demo_1

安装链码包

Org1 peer节点安装链码

export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=localhost:7051

使用peer lifecycle chaincode install 命令在peer节点上安装链码

peer lifecycle chaincode install hyperledger-fabric-contract-java-demo.tar.gz

Org2 peer节点安装链码

export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051

使用peer lifecycle chaincode install 命令在peer节点上安装链码

peer lifecycle chaincode install hyperledger-fabric-contract-java-demo.tar.gz

通过链码定义

查询包ID

peer lifecycle chaincode queryinstalled

批准链码时，我们将使用包 ID，所以让我们继续将其保存为环境变量。将返回的包 ID 粘贴到下面的命令中

export CC_PACKAGE_ID=（加上上面获取到的包ID）hyperledger-fabric-contract-java-demo_1:54a21ac334812b0505cd548f1aed0bc0a7b603eef44c98a17ef05f004737b451

Org2通过链码定义

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Org1通过链码定义

export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:7051

将链码定义批准为 Org1

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

将链码定义提交给通道

使用peer lifecycle chaincode checkcommitreadiness命令检查通道成员是否批准了相同的链码定义

peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json

使用peer lifecycle chaincode commit 将链码定义提交到通道，commit命令还需由组织管理员提交

peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt

使用peer lifecycle chaincode querycommitted命令来确认链代码定义已提交到通道

peer lifecycle chaincode querycommitted --channelID mychannel --name hyperledger-fabric-contract-java-demo --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

调用链码
