Hyperledegr Fabric BYFN 4: byfn.sh up 操作分析 docker exec

script.sh

script.sh 精简代码逻辑

相关函数涉及文件： scripts/utils.sh

流程：

1. 创建通道

   • createChannel

     setGlobals 0 1 # 设置peer和org参数
     peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx >&log.txt
     

2. 将所有peer结点加入到通道

   • joinChannel

     for org in 1 2; do
       for peer in 0 1; do
         joinChannelWithRetry $peer $org
       done
     done
     

   • joinChannelWithRetry

     ## Sometimes Join takes time hence RETRY at least 5 times
     joinChannelWithRetry() {
       PEER=$1
       ORG=$2
       setGlobals $PEER $ORG
       peer channel join -b $CHANNEL_NAME.block >&log.txt
     }
     

3. 在通道中为每个组织设置锚结点

   • updateAnchorPeers 0 1
updateAnchorPeers 0 2

     updateAnchorPeers() {
       PEER=$1
       ORG=$2
       setGlobals $PEER $ORG
     
       peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/${CORE_PEER_LOCALMSPID}anchors.tx >&log.txt
     }
     

4. 在peer0.org1和peer0.org2上安装链码

   • installChaincode 0 1
installChaincode 0 2

     installChaincode() {
       PEER=$1
       ORG=$2
       setGlobals $PEER $ORG
     
       peer chaincode install -n mycc -v ${VERSION} -l ${LANGUAGE} -p ${CC_SRC_PATH} >&log.txt
     }
     

5. 在peer0.org2上实例化代码

   • instantiateChaincode 0 2

     instantiateChaincode() {
       PEER=$1
       ORG=$2
       setGlobals $PEER $ORG
       VERSION=${3:-1.0}
     
       peer chaincode instantiate -o orderer.example.com:7050 -C $CHANNEL_NAME -n mycc -l ${LANGUAGE} -v ${VERSION} -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')" >&log.txt
     }
     

6. 在peer0.org1上查询链码

   • chaincodeQuery 0 1 100

   chaincodeQuery() {
     PEER=$1
     ORG=$2
     setGlobals $PEER $ORG
     EXPECTED_RESULT=$3
   
     peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}' >&log.txt
     test $res -eq 0 && VALUE=$(cat log.txt | awk '/Query Result/ {print $NF}')
     test "$VALUE" = "$EXPECTED_RESULT" && let rc=0
     # removed the string "Query Result" from peer chaincode query command
     # result. as a result, have to support both options until the change
     # is merged.
     test $rc -ne 0 && VALUE=$(cat log.txt | egrep '^[0-9]+$')
     test "$VALUE" = "$EXPECTED_RESULT" && let rc=0
     if test $rc -eq 0; then
       echo "===================== Query successful on peer${PEER}.org${ORG} on channel '$CHANNEL_NAME' ===================== "
     fi
   }
   

7. 在peer0.org1和peer0.org2上激活链码

   • chaincodeInvoke 0 1 0 2

     chaincodeInvoke() {
       parsePeerConnectionParameters $@ # 检查peers和关联组织数量是否偶数并设置$PEER_CONN_PARMS和$PEERS
     
       # 当`peer chaincode` 命令可以从peer中获得排序结点的地址，可以直接使用`-o` 选项
       peer chaincode invoke -o orderer.example.com:7050 -C $CHANNEL_NAME -n mycc $PEER_CONN_PARMS -c '{"Args":["invoke","a","b","10"]}' >&log.txt
     }
     

8. 在peer1.org2上实例化代码

   • instantiateChaincode 1 2

9. 在peer1.org2上查询链码，检查返回结果是否为90

   • chaincodeQuery 1 2 90
