Fabric智能合约编写，部署，调用

开启网络

cd /root/go/src/github.com/hyperledger/fabric-samples/test-network
./network.sh down
./network.sh up createChannel

打包智能合约

进入fabric-samples文件夹下的chaincode/fabcar/go目录下
执行GO111MODULE=on go mod vendor下载依赖（文件夹下已经有go.mod，不需要使用go mod init生成该module文件）
进入到/root/go/src/github.com/hyperledger/fabric-samples/test-network文件下
使用以下命令将二进制文件添加到cli路径：export PATH=${PWD}/../bin:$PATH
还需要设置FABRIC_CFG_PATH路径指向fabric-samples中的core.yaml文件，命令如下：export FABRIC_CFG_PATH=$PWD/../config/
检查peer命令是否可以使用：peer version
打包智能合约：peer lifecycle chaincode package fabcar.tar.gz --path ../chaincode/fabcar/go/ --lang golang --label fabcar_1.0 (../chaincode/fabcar/go/路径保证准确，fabcar_1.0自定义命名)

安装，批准，打包好的链码

切换到组织1

设置允许org1操作peer cli的环境变量：

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

安装智能合约（时间会比较久，耐心稍等）
peer lifecycle chaincode install fabcar.tar.gz
输出结果：

批准同意合约定义

查询已经安装的链码

当前组织批准同意链码定义：

export CC_PACKAGE_ID=fabcar_1.0:dfb655dc2702090da647bcbafc8e0a06f6f9d15e62ec97bb8653d60671e84bc9

此时检查合约定义是否满足策略
peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name fabcar --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
输出：

                "Org2MSP": false
        }
}

Org2MSP这里显示未同意合约定义
那么需要进入Org2中的环境配置中重复合约安装并同意合约定义

切换到组织2

设置允许org1操作peer cli的环境变量：

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

安装智能合约（时间会比较久，耐心稍等）

        }
}

过半数组织同意了智能合约定义
那么可以提交智能合约

提交智能合约到通道

提交
