chaincode_examples

1、证书配置、channel配置、docker配置见tools文件夹
cryptogen generate --config crypto-config.yaml --output=crypto-config
mkdir channel-artifacts
export CHANNEL_NAME=onechannel
export FABRIC_CFG_PATH=$PWD (设置一个环境变量来告诉configtxgen哪里去寻找configtx.yaml)
configtxgen -outputBlock ./channel-artifacts/orderer.block -profile TwoOrgsOrdererGenesis
configtxgen -outputCreateChannelTx ./channel-artifacts/onechannel.tx -profile TwoOrgsChannel -channelID onechannel
2、进入tools容器，执行chaincode的测试
export CHANNEL_NAME=onechannel
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./onechannel.tx
peer channel join -b onechannel.block

chaincode_example01

install chaincode

peer chaincode install -n chaincode_example01 -v 1.0 -p github.com/hyperledger/fabric/peer/chaincode/go/chaincode_example01

init chaincode

peer chaincode instantiate -o orderer.example.com:7050 -C onechannel -n chaincode_example01 -v 1.0 -c '{"Args":["init","a","100","b","200"]}'

invoke chaincode

peer chaincode invoke -C onechannel -n chaincode_example01 -v 1.0 -c '{"Args":["invoke","20"]}'

upgrade chaincode

peer chaincode install -n chaincode_example01 -v 2.0 -p github.com/hyperledger/fabric/peer/chaincode/go/chaincode_example01
peer chaincode upgrade -C onechannel -n chaincode_example01 -v 2.0 -c '{"Args":["init","a","1000","b","2000"]}'

chaincode_example02

install chaincode

peer chaincode install -n chaincode_example02 -v 1.0 -p github.com/hyperledger/fabric/peer/chaincode/go/chaincode_example02

init chaincode

peer chaincode instantiate -o orderer.example.com:7050 -C onechannel -n chaincode_example02 -v 1.0 -c '{"Args":["init","a","100","b","200"]}'

invoke chaincode

peer chaincode invoke -C onechannel -n chaincode_example02 -v 1.0 -c '{"Args":["invoke","a","b","20"]}'

query chaincode

peer chaincode query -C onechannel -n chaincode_example02 -v 1.0 -c '{"Args":["query","a"]}'

stub.DelState

peer chaincode invoke -C onechannel -n chaincode_example02 -v 1.0 -c '{"Args":["delete","a"]}'

chaincode_example03 ？？？？

install chaincode

peer chaincode install -n chaincode_example03 -v 1.0 -p github.com/hyperledger/fabric/peer/chaincode/go/chaincode_example03

init chaincode

peer chaincode instantiate -o orderer.example.com:7050 -C onechannel -n chaincode_example03 -v 1.0 -c '{"Args":["init","a","100"]}'

invoke chaincode

peer chaincode invoke -C onechannel -n chaincode_example03 -v 1.0 -c '{"Args":["query","a","20"]}'

chaincode_example04

install chaincode

peer chaincode install -n chaincode_example04 -v 1.0 -p github.com/hyperledger/fabric/peer/chaincode/go/chaincode_example04

init chaincode

peer chaincode instantiate -o orderer.example.com:7050 -C onechannel -n chaincode_example04 -v 1.0 -c '{"Args":["init","a","100"]}'

stub.InvokeChaincode 如果两个chaincode位于同一个channel，那么最后一个参数可为空，即不需要指明channel名称

peer chaincode invoke -C onechannel -n chaincode_example04 -v 1.0 -c '{"Args":["invoke","chaincode_example02","a","1","onechannel"]}'

query chaincode

peer chaincode query -C onechannel -n chaincode_example04 -v 1.0 -c '{"Args":["query","a"]}'

query chaincode

peer chaincode query -C onechannel -n chaincode_example04 -v 1.0 -c '{"Args":["query","a","chaincode_example02","a","onechannel"]}'

chaincode_example05 同一个channel内chaincode互调/跨channel的chaincode调用

install chaincode

peer chaincode install -n chaincode_example05 -v 1.0 -p github.com/hyperledger/fabric/peer/chaincode/go/chaincode_example05

init chaincode

peer chaincode instantiate -o orderer.example.com:7050 -C onechannel -n chaincode_example05 -v 1.0 -c '{"Args":["init","a","100"]}'

stub.InvokeChaincode 如果两个chaincode位于同一个channel，那么最后一个参数可为空，即不需要指明channel名称

peer chaincode invoke -C onechannel -n chaincode_example05 -v 1.0 -c '{"Args":["invoke","chaincode_example02","sum","onechannel"]}'

query chaincode

peer chaincode query -C onechannel -n chaincode_example05 -v 1.0 -c '{"Args":["query","chaincode_example02","sum",""]}'

跨channel调用chaincode，例子：在onechannel的chaincode_example05里面调用anotherchannel的chaincode_example02

生成第二个channel，anotherchannel

export FABRIC_CFG_PATH=$PWD
configtxgen -outputCreateChannelTx ./anotherchannel.tx -profile TwoOrgsChannel -channelID anotherchannel

peer创建新的channel，加入新的channel

peer channel create -o orderer.example.com:7050 -c anotherchannel -f ./anotherchannel.tx peer channel join -b anotherchannel.block

install chaincode

peer chaincode install -n chaincode_example02 -v 1.0 -p github.com/hyperledger/fabric/peer/chaincode/go/chaincode_example02

init chaincode

peer chaincode instantiate -o orderer.example.com:7050 -C anotherchannel -n chaincode_example02 -v 1.0 -c '{"Args":["init","a","100","b","200"]}'

跨channel调用chaincode

peer chaincode invoke -C onechannel -n chaincode_example05 -v 1.0 -c '{"Args":["invoke","chaincode_example02","sum","anotherchannel"]}'
