Chain Code Description

1. 네트워크 초기화

./network.sh down

2. 네트워크 가동, 채널 생성

./network.sh up createChannel

3. 피어에 체인코드 deploy

./network.sh deployCC -ccn basic -ccp ../sto-transfer-test/chaincode-go -ccl go
*터미널 split 후
./monitordocker.sh fabric_test

4. 환경변수 설정

export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=$PWD/../config/
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${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/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:7051

5. Ledger 초기화

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":[]}'

6. 새 계정 생성

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":"CreateAccount","Args":["user101", "1000000", "100"]}'

7. Query

(1)peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAccounts"]}'
(2)peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAccount", "User1"]}'
(3)peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllTransfers"]}'

8.submitTransferBatch

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":"ProcessTransferBatch","Args":["[{\"FromAddress\":\"user101\",\"Price\":100,\"ST_ID\":\"ST_1\",\"Size\":3,\"TransferId\":\"transfer1\",\"ToAddress\":\"user103\"},{\"FromAddress\":\"user102\",\"Price\":100,\"ST_ID\":\"ST_1\",\"Size\":1,\"TransferId\":\"transfer2\",\"ToAddress\":\"user103\"},{\"FromAddress\":\"user102\",\"Price\":100,\"ST_ID\":\"ST_1\",\"Size\":4,\"TransferId\":\"transfer3\",\"ToAddress\":\"user104\"}]"]}' (편집됨)
