How to run "peer chaincode invoke" to invoke the transaction on the chaincode instance?
✍: FYIcenter.com
After a chaincode in properly installed on all peers and instantiated on the channel, you can run the "peer chaincode invoke" to invoke the transaction on the chaincode instance.
1. Verify instantiated chaincode:
$ docker exec -it cli bash bash-4.4# echo $CORE_PEER_ADDRESS peer0.org1.example.com:7051 bash-4.4# peer chaincode list -C mychannel --instantiated Get instantiated chaincodes on channel mychannel: Name: mycc, Version: 2.0, Path: github.com/chaincode/chaincode_example02/go/, \ Escc: escc, Vscc: vscc
2. Query chaincode instance properties:
bash-4.4# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}' 100 bash-4.4# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","b"]}' 200
3. Invoke chaincode instance to transfer 10 from property "a" to "b":
bash-4.4# peer chaincode invoke -o orderer.example.com:7050 --tls true \ --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto\ /ordererOrganizations/example.com/orderers/orderer.example.com/msp\ /tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc \ --peerAddresses peer0.org1.example.com:9051 --tlsRootCertFiles \ /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations\ /org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \ --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles \ /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations\ /org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \ -c '{"Args":["invoke","a","b","10"]}' [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. \ result: status:200
4. Query chaincode instance properties again:
bash-4.4# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}' 90 bash-4.4# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","b"]}' 210
The transfer transaction was done correctly!
