  - 使用peer CLI测试链码
  - 调用链码

启动测试网络

cd fabric-samples/test-network

network.sh的脚本语法是：network.sh <mode> [flag]

在这里插入图片描述

./network.sh up

./network.sh createChannel

在java源码路径下

chmod +744 gradlew
vim gradlew
:set ff=unix
:wq
./gradlew run

回到test-network路径下

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-java -ccl java

在这里插入图片描述

使用peer CLI测试链码

设置环境变量

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

作为Org1操作peer CLI：

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

调用链码

初始化账本

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --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 -c '{"function":"InitLedger","Args":[]}'

在这里插入图片描述

查询账本

peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAssets"]}'

在这里插入图片描述

修改账本

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --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 -c '{"function":"TransferAsset","Args":["asset6","Christopher"]}'
