一、编写一个转账的合约

  1. 创建合约文件，命令：touch /home/test_fabric/chaincodes/test.go
  2. 编写内容
package main

import (
	"fmt"
	"github.com/hyperledger/fabric-chaincode-go/shim"
	"github.com/hyperledger/fabric-protos-go/peer"
	"strconv"
)

// SimpleChaincode example simple Chaincode implementation
type SimpleChaincode struct {
}

func (t *SimpleChaincode) Init(stub shim.ChaincodeStubInterface) peer.Response {
	fmt.Println("ex02 Init")
	_, args := stub.GetFunctionAndParameters()
	var A, B string    // Entities
	var Aval, Bval int // Asset holdings
	var err error

	if len(args) != 4 {
		return shim.Error("Incorrect number of arguments. Expecting 4")
	}

	// Initialize the chaincode
	A = args[0]
	Aval, err = strconv.Atoi(args[1])
	if err != nil {
		return shim.Error("Expecting integer value for asset holding")
	}
	B = args[2]
	Bval, err = strconv.Atoi(args[3])
	if err != nil {
		return shim.Error("Expecting integer value for asset holding")
	}
	fmt.Printf("Aval = %d, Bval = %d\n", Aval, Bval)

	// Write the state to the ledger
	err = stub.PutState(A, []byte(strconv.Itoa(Aval)))
	if err != nil {
		return shim.Error(err.Error())
	}

	err = stub.PutState(B, []byte(strconv.Itoa(Bval)))
	if err != nil {
		return shim.Error(err.Error())
	}

	return shim.Success(nil)
}

func (t *SimpleChaincode) Invoke(stub shim.ChaincodeStubInterface) peer.Response {
	fmt.Println("ex02 Invoke")
	function, args := stub.GetFunctionAndParameters()
	if function == "invoke" {
		// Make payment of X units from A to B
		return t.invoke(stub, args)
	} else if function == "delete" {
		// Deletes an entity from its state
		return t.delete(stub, args)
	} else if function == "query" {
		// the old "Query" is now implemtned in invoke
		return t.query(stub, args)
	}

	return shim.Error("Invalid invoke function name. Expecting \"invoke\" \"delete\" \"query\"")

	var err error

	if len(args) != 3 {
		return shim.Error("Incorrect number of arguments. Expecting 3")
	}

	A = args[0]
	B = args[1]

	// Get the state from the ledger
	// TODO: will be nice to have a GetAllState call to ledger
	Avalbytes, err := stub.GetState(A)
	if err != nil {
		return shim.Error("Failed to get state")
	}
	if Avalbytes == nil {
		return shim.Error("Entity not found")
	}
	Aval, _ = strconv.Atoi(string(Avalbytes))

	Bvalbytes, err := stub.GetState(B)
	if err != nil {
		return shim.Error("Failed to get state")
	}
	if Bvalbytes == nil {

	}
	Bval, _ = strconv.Atoi(string(Bvalbytes))

	// Perform the execution
	X, err = strconv.Atoi(args[2])
	if err != nil {
		return shim.Error("Invalid transaction amount, expecting a integer value")
	}
	Aval = Aval - X
	Bval = Bval + X
	fmt.Printf("Aval = %d, Bval = %d\n", Aval, Bval)

	// Write the state back to the ledger
	err = stub.PutState(A, []byte(strconv.Itoa(Aval)))
	if err != nil {
		return shim.Error(err.Error())
	}

	err = stub.PutState(B, []byte(strconv.Itoa(Bval)))
	if err != nil {
		return shim.Error(err.Error())
	}

	return shim.Success(nil)
}

// Deletes an entity from state
func (t *SimpleChaincode) delete(stub shim.ChaincodeStubInterface, args []string) peer.Response {
	if len(args) != 1 {
		return shim.Error("Incorrect number of arguments. Expecting 1")
	}

	A := args[0]

	// Delete the key from the state in ledger
	err := stub.DelState(A)
	if err != nil {
		return shim.Error("Failed to delete state")
	}

	return shim.Success(nil)
}

// query callback representing the query of a chaincode
func (t *SimpleChaincode) query(stub shim.ChaincodeStubInterface, args []string) peer.Response {
	var A string // Entities
	var err error

	if len(args) != 1 {
		return shim.Error("Incorrect number of arguments. Expecting name of the person to query")
	}

	A = args[0]

	// Get the state from the ledger
	Avalbytes, err := stub.GetState(A)
	if err != nil {

		return shim.Error(jsonResp)
	}

	jsonResp := "{\"Name\":\"" + A + "\",\"Amount\":\"" + string(Avalbytes) + "\"}"
	fmt.Printf("Query Response:%s\n", jsonResp)
	return shim.Success(Avalbytes)
}

func main() {
	err := shim.Start(new(SimpleChaincode))
	if err != nil {
		fmt.Printf("Error starting Simple chaincode: %s", err)
	}
}

4.1、在org2-peer0上对链码进行审批，并指定背书策略

  1. 进入cli容器，命令：docker exec -it fabric-cli /bin/bash
  2. 进入容器的tmp目录，命令：cd /tmp
  3. 设置环境变量，使用org2-peer0身份
export org=2
export peer=0
export CORE_PEER_LOCALMSPID=Org${org}MSP
export CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051
export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt
  1. 对链码进行审批，并通过属性--signature-policy指定背书策略，命令
#没有开启tls
peer lifecycle chaincode approveformyorg --peerAddresses ${CORE_PEER_ADDRESS} --channelID businesschannel --name test_chaincode --version 1.0 --init-required --package-id test_chaincode:6afa06381da3894197917b23017e474470dbb072c80257dc9103b7a214915dae --sequence 1 --signature-policy "OR ('Org1MSP.member','Org2MSP.member')" --waitForEvent --orderer orderer0.example.com:7050
#开启tls
peer lifecycle chaincode approveformyorg --peerAddresses ${CORE_PEER_ADDRESS} --tlsRootCertFiles ${CORE_PEER_TLS_ROOTCERT_FILE} --channelID businesschannel --name test_chaincode --version 1.0 --init-required --package-id test_chaincode:6afa06381da3894197917b23017e474470dbb072c80257dc9103b7a214915dae --sequence 1 --signature-policy "OR ('Org1MSP.member','Org2MSP.member')" --waitForEvent --orderer orderer0.example.com:7050 --tls true --cafile /etc/hyperledger/fabric/crypto-config/ordererOrganizations/example.com/orderers/orderer0.example.com/tls/ca.crt

五、查询指定peer上审批过的chaincode

5.1、在org1-peer0上进行查询

  1. 进入cli容器，命令：docker exec -it fabric-cli /bin/bash
  2. 进入容器的tmp目录，命令：cd /tmp
  3. 设置环境变量，使用org1-peer0身份
export org=1
export peer=0
export CORE_PEER_LOCALMSPID=Org${org}MSP
export CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051
export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt
  1. 查询审批结果，命令
peer lifecycle chaincode queryapproved --peerAddresses ${CORE_PEER_ADDRESS} --tlsRootCertFiles ${CORE_PEER_TLS_ROOTCERT_FILE} --channelID businesschannel --name test_chaincode --output json
  1. 返回该节点org1-peer0审批过的chancode，这里只审批了test_chaincode，所以只有chaincode
    实验第七节——用户chaincode相关操作

5.2、在org2-peer0上进行查询

  1. 进入cli容器，命令：docker exec -it fabric-cli /bin/bash
  2. 进入容器的tmp目录，命令：cd /tmp
  3. 设置环境变量，使用org2-peer0身份
export org=2
export peer=0
export CORE_PEER_LOCALMSPID=Org${org}MSP
export CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051
export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt
  1. 查询审批结果，命令
peer lifecycle chaincode queryapproved --peerAddresses ${CORE_PEER_ADDRESS} --tlsRootCertFiles ${CORE_PEER_TLS_ROOTCERT_FILE} --channelID businesschannel --name test_chaincode --output json

六、查询指定chaincode是否可以提交

  1. 查询意义：在chaincode安装时，经历了审批步骤如第四步，并通过属性--signature-policy指定背书策略，所以指定chaincode需要满足了指定的背书策略，才可以提交并使用

6.1、在org1-peer0上查询

  1. 进入cli容器，命令：docker exec -it fabric-cli /bin/bash
  2. 进入容器的tmp目录，命令：cd /tmp
  3. 设置环境变量，使用org1-peer0身份
export org=1
export peer=0
export CORE_PEER_LOCALMSPID=Org${org}MSP
export CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051
export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt
  1. 查询审批结果，命令
peer lifecycle chaincode checkcommitreadiness --channelID businesschannel --name test_chaincode --version 1.0 --output json --sequence 1

七、向通道提交链码

  1. 提交可以在一个peer上完成，这里使用org1-peer0进行操作
  2. 进入cli容器，命令：docker exec -it fabric-cli /bin/bash
  3. 进入容器的tmp目录，命令：cd /tmp
  4. 设置环境变量，使用org1-peer0身份
export org=1
export peer=0
export CORE_PEER_LOCALMSPID=Org${org}MSP
export CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051
export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt
  1. 使用org1-per0以及org2-peer0的证书，将chaincode提交到这两个节点上，命令
# 开启tls
peer lifecycle chaincode commit -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode --version 1.0 --init-required --sequence 1 \
  --peerAddresses peer0.org1.example.com:7051 \
  --tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \
  --peerAddresses peer0.org2.example.com:7051 \
  --tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \
  --waitForEvent \
  --signature-policy "OR ('Org1MSP.member','Org2MSP.member')" \
  --tls true \
  --cafile /etc/hyperledger/fabric/crypto-config/ordererOrganizations/example.com/orderers/orderer0.example.com/tls/ca.crt
# 未开启tls
peer lifecycle chaincode commit -o orderer0.example.com:7050 --channelID businesschannel --name test_chaincode --version 1.0 --init-required --sequence 1 \
  --peerAddresses peer0.org1.example.com:7051 \
  --tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \
  --peerAddresses peer0.org2.example.com:7051 \
  --tlsRootCertFiles /etc/hyperledger/fabric/crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \
  --waitForEvent \
  --signature-policy "OR ('Org1MSP.member','Org2MSP.member')"

实验第七节——用户chaincode相关操作

八、查询指定通道上已经提交的链码

  1. 这里使用org1-peer0的身份进行查询，因为channel在org1与org2之间，所以用一个节点查询即可
  2. 进入cli容器，命令：docker exec -it fabric-cli /bin/bash
  3. 进入容器的tmp目录，命令：cd /tmp
  4. 设置环境变量，使用org1-peer0身份
export org=1
export peer=0
export CORE_PEER_LOCALMSPID=Org${org}MSP
export CORE_PEER_ADDRESS=peer${peer}.org${org}.example.com:7051
export CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/users/Admin@org${org}.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/crypto-config/peerOrganizations/org${org}.example.com/peers/peer${peer}.org${org}.example.com/tls/ca.crt
  1. 查询命令
peer lifecycle chaincode querycommitted --channelID businesschannel --output json
  1. 可以看到chaincode_definitions属性里的数组只有一个值：test_chaincode
