链码操作

1.创建通道：

peer channel create -o orderer.wisedu.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx

2.加入通道：在对应peer节点下执行（要想加入某通道，必须有该通道的block文件）

peer channel join -b $CHANNEL_NAME.block

3.更新锚节点：

peer channel update -o orderer.6.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/${CORE_PEER_LOCALMSPID}anchors.tx

其中，${CORE_PEER_LOCALMSPID}对应当前操作的peer节点所属MSPID，取值例如：{“Org1MSP”,"Org2MSP"}

4.安装链码（在每个peer节点）：

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

5.实例化链码（只需在一个peer节点实例化一次）：

peer chaincode instantiate -o orderer.wisedu.com:7050 -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR    ('Org1MSP.peer','Org2MSP.peer')"

6.查询

peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'

7.转账

peer chaincode invoke -o orderer.wisedu.com:7050 -C $CHANNEL_NAME -n mycc -c '{"Args":["invoke","a","b","10"]}'

 

8.$CHANNEL_NAME.block从docker中拷贝出来

sudo docker cp [879433a63002]:/opt/gopath/src/github.com/hyperledger/fabric/peer/mychannel.block /home/shirly/projects/fabric/examples/e2e_cli/channel-artifacts/

其中， [879433a63002]是链码所在容器ID,即peer客户端的cli

9.从宿主机拷贝进去docker

sudo docker cp /home/shirly/projects/fabric/examples/e2e_cli/channel-artifacts/mychannel.block [xxxxxxxxxxx]:/opt/gopath/src/github.com/hyperledger/fabric/peer/

其中， [xxxxxxxxxxx]也是对应peer节点的客户端cli容器的ID
