一、启动测试网络

1.进入test-network目录

cd fabric-samples/test-network

2.在test-network目录中，运行以下命令删除先前运行的所有容器或工程

./network.sh down

3.过执行以下命令来启动网络

./network.sh up

此命令创建一个由两个peer节点和一个order节点组成的Fabric网络

二、测试网络的组成部分

运行以下命令以列出所有正在您的计算机上运行的Docker容器

docker ps -a

三、创建一个通道

1. 运行以下命令以创建一个默认名称为“ mychannel”的通道

./network.sh createChannel

四、在channel启动一个链码

1.使用以下命令在通道上启动链码

./network.sh deployCC

五、与网络交互

1.使用以下命令将这些二进制文件添加到您的CLI路径

export PATH=${PWD}/../bin:$PATH

2.还需要将fabric-samples代码库中的FABRIC_CFG_PATH设置为指向其中的core.yaml文件

export FABRIC_CFG_PATH=$PWD/../config/

3.设置环境变量，以允许您作为Org1操作peer CLI

export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=localhost:7051

4.运行以下命令以获取已添加到通道账本中的汽车列表

peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'

运行上面指令前需要执行如下：
新开一个命令窗口
执行启动指令：cd fabric-samples/fabcar后，
执行./startFabric.sh，等待完成即可。
最后再继续运行之前的指令

peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'

可以得到如下结果：

[{ "Key":"CAR0","Record":{ "make":"Toyota","model":"Prius","colour":"blue","owner":"Tomoko"}},{ "Key":"CAR1","Record":{ "make":"Ford","model":"Mustang","colour":"red","owner":"Brad"}},{ "Key":"CAR2","Record":{ "make":"Hyundai","model":"Tucson","colour":"green","owner":"Jin Soo"}},{ "Key":"CAR3","Record":{ "make":"Volkswagen","model":"Passat","colour":"yellow","owner":"Max"}},{ "Key":"CAR4","Record":{ "make":"Tesla","model":"S","colour":"black","owner":"Adriana"}},{ "Key":"CAR5","Record":{ "make":"Peugeot","model":"205","colour":"purple","owner":"Michel"}},{ "Key":"CAR6","Record":{ "make":"Chery","model":"S22L","colour":"white","owner":"Aarav"}},{ "Key":"CAR7","Record":{ "make":"Fiat","model":"Punto","colour":"violet","owner":"Pari"}},{ "Key":"CAR8","Record":{ "make":"Tata","model":"Nano","colour":"indigo","owner":"Valeria"}},{ "Key":"CAR9","Record":{ "make":"Holden","model":"Barina","colour":"brown","owner":"Shotaro"}}]

5.使用以下命令调用fabcar链码来更改账本上汽车的所有者

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n fabcar --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"changeCarOwner","Args":["CAR9","Dave"]}'

如果命令成功，应该看到以下响应：

2020-9-04 17:38:21.048 EST [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200

6.设置以下环境变量以作为Org2进行操作

export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051

7.现在可以查询运行在peer0.org2.example.com的fabcar链码

peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryCar","CAR9"]}'

结果将显示"CAR9"已转移到Dave：

{ "make":"Holden","model":"Barina","colour":"brown","owner":"Dave"}

六、关停网络

使用完测试网络后，您可以使用以下命令关闭网络

./network.sh down
