[Fabric]-First-Network(script.sh文件详解)

推荐fabric命令查询地址:看不懂可以直接查 fabric命令手册

我理解的也没多好,新手上路,希望大家看到的可以指点一下。

一、script.sh

echo

二、utils.sh方法

1. 公用的信息

echo "先定义了orderer 和 3 个peer 的ca证书的位置"
ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
PEER0_ORG1_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
PEER0_ORG2_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
PEER0_ORG3_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org3.example.com/peers/peer0.org3.example.com/tls/ca.crt

2. 检测

# verify the result of the end-to-end test
verifyResult() {
echo "verifyResult 创建e 2 e 使用"
  if [ $1 -ne 0 ]; then
    echo "!!!!!!!!!!!!!!! "$2" !!!!!!!!!!!!!!!!"
    echo "========= ERROR !!! FAILED to execute End-2-End Scenario ==========="
    echo
    exit 1
  fi
}

3. 设置OrdererOrg.Admin全局

# Set OrdererOrg.Admin globals
setOrdererGlobals() {
  CORE_PEER_LOCALMSPID="OrdererMSP"
  CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
  CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/users/[email protected]/msp
}

4. 设置全局

setGlobals() {
  PEER=$1
  ORG=$2
  if [ $ORG -eq 1 ]; then
    # 定义peer 的msp 的位置 tls 啦
    CORE_PEER_LOCALMSPID="Org1MSP"
    CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA
    CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
    if [ $PEER -eq 0 ]; then
      # 根据peer 0 1 定义 访问名 ip:port
      CORE_PEER_ADDRESS=peer0.org1.example.com:7051
    else
      CORE_PEER_ADDRESS=peer1.org1.example.com:8051
    fi
  elif [ $ORG -eq 2 ]; then
    CORE_PEER_LOCALMSPID="Org2MSP"
    CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG2_CA
    CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp
    if [ $PEER -eq 0 ]; then
      CORE_PEER_ADDRESS=peer0.org2.example.com:9051
    else
      CORE_PEER_ADDRESS=peer1.org2.example.com:10051
    fi

  elif [ $ORG -eq 3 ]; then
    CORE_PEER_LOCALMSPID="Org3MSP"
    CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG3_CA
    CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org3.example.com/users/[email protected]/msp
    if [ $PEER -eq 0 ]; then
      CORE_PEER_ADDRESS=peer0.org3.example.com:11051
    else
      CORE_PEER_ADDRESS=peer1.org3.example.com:12051
    fi
  else
    echo "================== ERROR !!! ORG Unknown =================="
  fi

  if [ "$VERBOSE" == "true" ]; then
    env | grep CORE
  fi
}

5. 更新锚节点

updateAnchorPeers() {
  PEER=$1
  ORG=$2
  setGlobals $PEER $ORG

  if [ -z "$CORE_PEER_TLS_ENABLED" -o "$CORE_PEER_TLS_ENABLED" = "false" ]; then
    set -x
    echo "更新锚节点"
    peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/${CORE_PEER_LOCALMSPID}anchors.tx >&log.txt
    res=$?
    set +x
  else
    set -x
    peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/${CORE_PEER_LOCALMSPID}anchors.tx --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA >&log.txt
    res=$?
    set +x
  fi
  cat log.txt
  echo "锚节点更新失败"
  verifyResult $res "Anchor peer update failed"
  echo "===================== Anchor peers updated for org '$CORE_PEER_LOCALMSPID' on channel '$CHANNEL_NAME' ===================== "
  sleep $DELAY
  echo
}

6. 加入通道

## Sometimes Join takes time hence RETRY at least 5 times
joinChannelWithRetry() {
  PEER=$1
  ORG=$2
  # 调用设置全局
  [setGlobals](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#9TrZv7UFE2vBofkf4Q4Yma) $PEER $ORG
  set -x

  echo "指定节点加入一个通道中 加入创世块定义的通道中"
  peer channel join -b $CHANNEL_NAME.block >&log.txt
  res=$?
  set +x
  cat log.txt
  if [ $res -ne 0 -a $COUNTER -lt $MAX_RETRY ]; then
    COUNTER=$(expr $COUNTER + 1)
    echo "peer${PEER}.org${ORG} failed to join the channel, Retry after $DELAY seconds"
    sleep $DELAY
    joinChannelWithRetry $PEER $ORG
  else
    COUNTER=1
  fi
  verifyResult $res "After $MAX_RETRY attempts, peer${PEER}.org${ORG} has failed to join channel '$CHANNEL_NAME' "
}

7. 安装链码

installChaincode() {
  PEER=$1
  ORG=$2
  [setGlobals](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#9TrZv7UFE2vBofkf4Q4Yma)[ ](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#9TrZv7UFE2vBofkf4Q4Yma)$PEER $ORG
  VERSION=${3:-1.0}
  set -x
  echo "执行peer chaincode install -n -v -l -p  再输出到log中"
  peer chaincode install -n mycc -v ${VERSION} -l ${LANGUAGE} -p ${CC_SRC_PATH} >&log.txt
  res=$?
  set +x
  cat log.txt
  verifyResult $res "Chaincode installation on peer${PEER}.org${ORG} has failed"
  echo "===================== Chaincode is installed on peer${PEER}.org${ORG} ===================== "
  echo
}

8. 实例化链码

instantiateChaincode() {
  PEER=$1
  ORG=$2
  setGlobals $PEER $ORG
  VERSION=${3:-1.0}

  # while 'peer chaincode' command can get the orderer endpoint from the peer
  # (if join was successful), let's supply it directly as we know it using
  # the "-o" option
  echo "判断有没有开tls"
  if [ -z "$CORE_PEER_TLS_ENABLED" -o "$CORE_PEER_TLS_ENABLED" = "false" ]; then
    set -x
    echo "执行实例化链码  a=100 b=200"
    peer chaincode instantiate -o orderer.example.com:7050 -C $CHANNEL_NAME -n mycc -l ${LANGUAGE} -v ${VERSION} -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')" >&log.txt
    res=$?
    set +x
  else
    set -x
    peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -l ${LANGUAGE} -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')" >&log.txt
    res=$?
    set +x
  fi
  cat log.txt
  verifyResult $res "Chaincode instantiation on peer${PEER}.org${ORG} on channel '$CHANNEL_NAME' failed"
  echo "===================== Chaincode is instantiated on peer${PEER}.org${ORG} on channel '$CHANNEL_NAME' ===================== "
  echo
}

9. 升级链码

upgradeChaincode() {
  PEER=$1
  ORG=$2
  [setGlobals](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#9TrZv7UFE2vBofkf4Q4Yma)[ ](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#9TrZv7UFE2vBofkf4Q4Yma)$PEER $ORG

  set -x
  echo "升级指定的链码。交易提交后新的链码立即替代原来的链码 参数 a=90 b=210"
  peer chaincode upgrade -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -v 2.0 -c '{"Args":["init","a","90","b","210"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer','Org3MSP.peer')"
  res=$?
  set +x
  cat log.txt
  verifyResult $res "Chaincode upgrade on peer${PEER}.org${ORG} has failed"
  echo "===================== Chaincode is upgraded on peer${PEER}.org${ORG} on channel '$CHANNEL_NAME' ===================== "
  echo
}

10. 查询链码

chaincodeQuery() {
  PEER=$1
  ORG=$2
  setGlobals $PEER $ORG
  EXPECTED_RESULT=$3
  echo "===================== Querying on peer${PEER}.org${ORG} on channel '$CHANNEL_NAME'... ===================== "
  local rc=1
  local starttime=$(date +%s)

  # continue to poll
  # we either get a successful response, or reach TIMEOUT
  while
    test "$(($(date +%s) - starttime))" -lt "$TIMEOUT" -a $rc -ne 0
  do
    echo "$(($(date +%s) - starttime))"
    echo  "$TIMEOUT"
    echo $rc
    echo "判断开始时间 结束时间 rc不小于 0"
    echo "休息一段时间"
    sleep $DELAY
    echo "Attempting to Query peer${PEER}.org${ORG} ...$(($(date +%s) - starttime)) secs"
    set -x
    echo "查询a的钱"
    peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}' >&log.txt
    res=$?
    set +x
    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
  done
  echo
  cat log.txt
  echo "判断结果"
  if test $rc -eq 0; then
    echo "===================== Query successful on peer${PEER}.org${ORG} on channel '$CHANNEL_NAME' ===================== "
  else
    echo "!!!!!!!!!!!!!!! Query result on peer${PEER}.org${ORG} is INVALID !!!!!!!!!!!!!!!!"
    echo "================== ERROR !!! FAILED to execute End-2-End Scenario =================="
    echo
    exit 1
  fi
}

11. 将给定通道的配置写入json

# Writes the current channel config for a given channel to a JSON file
fetchChannelConfig() {
  CHANNEL=$1
  OUTPUT=$2

  setOrdererGlobals
  echo "提取指区块写入文件"
  echo "Fetching the most recent configuration block for the channel"
  if [ -z "$CORE_PEER_TLS_ENABLED" -o "$CORE_PEER_TLS_ENABLED" = "false" ]; then

    set +x
  else
    set -x
    peer channel fetch config config_block.pb -o orderer.example.com:7050 -c $CHANNEL --tls --cafile $ORDERER_CA
    set +x
  fi

  echo "将配置块解码为json   将一个protobuf消息转换为JSON格式。"
  echo "Decoding config block to JSON and isolating config to ${OUTPUT}"
  set -x
  configtxlator proto_decode --input config_block.pb --type common.Block | jq .data.data[0].payload.data.config >"${OUTPUT}"
  set +x
}

12. 更新签名

# 为指定的configtx更新文件原地签名。需要-f标志。
# ${TX} 可以查看这个文件前=前后大小变化
signConfigtxAsPeerOrg() {
 
  PEERORG=$1
  TX=$2
  setGlobals 0 $PEERORG
  set -x
  peer channel signconfigtx -f "${TX}"
  set +x
}

13. 更新配置信息

# createConfigUpdate <channel_id> <original_config.json> <modified_config.json> <output.pb>
# Takes an original and modified config, and produces the config update tx
# which transitions between the two
createConfigUpdate() {
  echo "计算生成两个common.Config消息之间的配置更新。"

  CHANNEL=$1
  ORIGINAL=$2
  MODIFIED=$3
  OUTPUT=$4

  set -x
  echo "将一个JSON文档转换为protobuf格式数据。"
  echo "input ${ORIGINAL} 转化为original_config.pb"
  configtxlator proto_encode --input "${ORIGINAL}" --type common.Config >original_config.pb
  configtxlator proto_encode --input "${MODIFIED}" --type common.Config >modified_config.pb
  echo "json 转 pb"
  configtxlator compute_update --channel_id "${CHANNEL}" --original original_config.pb --updated modified_config.pb >config_update.pb
  echo "pb 转 json "
  configtxlator proto_decode --input config_update.pb --type common.ConfigUpdate >config_update.json
  echo '{"payload":{"header":{"channel_header":{"channel_id":"'$CHANNEL'", "type":2}},"data":{"config_update":'$(cat config_update.json)'}}}' | jq . >config_update_in_envelope.json
  configtxlator proto_encode --input config_update_in_envelope.json --type common.Envelope >"${OUTPUT}"
  set +x
}

14. peer链接的参数

# parsePeerConnectionParameters [email protected]
# Helper function that takes the parameters from a chaincode operation
# (e.g. invoke, query, instantiate) and checks for an even number of
# peers and associated org, then sets $PEER_CONN_PARMS and $PEERS
parsePeerConnectionParameters() {
  echo "从链码汇总获取辅助参数"
  echo "检查 peer org 参数  不均匀的数量"
    # check for uneven number of peer and org parameters

15. 初始化链码

# chaincodeInvoke <peer> <org> ...
# Accepts as many peer/org pairs as desired and requests endorsement from each
chaincodeInvoke() {
  echo "初始化链码"
  [parsePeerConnectionParameters](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#n872ZyZk83zGv5T7VH2THG)[ ](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#n872ZyZk83zGv5T7VH2THG)[email protected]
