8.1 End-2-End案例简介
Fabric官方提供了实现点对点的Fabric网络示例，该网络有两个组织（organizations），一个组织有两种节点（Peer）,通过Kafka方式实现排序（Orderer）服务。
End-2-End案例的运行需要“cryptogen”和“configtxgen”两个工具，用于Fabric网络所需的数字证书验证和访问控制功能。
- cryptogen：生成用于识别和验证网络中各种组件的x509证书。
- configtxgen：生成用于通道和区块所需要配置文件。
两个工具可以通过如下命令方式生成，在该End-2-End例子中已集成到generateArtifacts.sh这个文件，运行后自动生成，无需手动命令操作,两个文件生成到$GOPATH/src/github.com/hyperledger /release/linux-amd64/bin这个目录。
# cd $GOPATH/src/github.com/hyperledger/fabric
# make release
# cd $GOPATH/src/github.com/hyperledger/release/linux-amd64/bin
还可以通过以下网址直接访问下载，地址：https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/，本书使用V1.2版本，对应文件为hyperledger-fabric-linux-amd64-1.2.0.tar.gz，下载完成后解压，获取bin目录。
8.2 End-2-End案例运行
1. 配置加速镜像
# mkdir -p /etc/docker
# tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://8w1wqmsz.mirror.aliyuncs.com"]
}
EOF
# systemctl daemon-reload
# systemctl restart docker
2. 下载加速镜像
# cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli
# source download-dockerimages.sh -c latest -f latest
删除镜像：
# docker rmi <image id>
# docker rmi -f<image id> //强制删除
删除全部镜像
# docker rmi $(docker images -q)
# docker rmi -f $(docker images -q) //强制删除
3. 查看下载镜像
4. 运行e2e_cli
# docker stop $(docker ps -a -q)
# docker rm $(docker ps -a -q)
# ./network_setup.sh up
显示start-e2e表示开始运行，如下图所示：
![]()
图：End-2-End开始运行
显示END-E2E表示运行成功，如下图所示：

图：End-2-End运行成功
8.3 End-2-End案例分析
8.3.1 案例架构
End-2-End案例由3个zookeeper、4个kafka和1个orderer实现排序,包括两个组织，分别为Org1和Org2，每个组织中有两个节点，分别为peer0和peer1,结构图如下所示：
![]()
图：End-2-End结构图
所有的配置都在docker-compose-cli.yaml文件里，配置顺序分别为zookeeper、kafka、orderer、peer和cli，先运行zookeeper集群、再运行kafka集群，最后运行orderer和peer，必须按照以上运行顺序；实现的功能集中写在script.sh文件里，自动运行全部功能，直到显示成功，具体功能如下：
1. 验证排序（orderer）服务是否可用，函数：checkOSNAvailability
2. 创建通道，函数：createChannel
3. 加入通道，函数：checkOSNAvailability
4. 更新组织1的锚节点，函数：updateAnchorPeers
5. 更新组织2的锚节点，函数：updateAnchorPeers
6. 在组织1的节点0上安装智能合约，函数：installChaincode
7. 在组织2的节点0上安装智能合约，函数：installChaincode
8. 在组织2的节点0上实例化智能合约，函数：instantiateChaincode
9. 在组织1的节点0上查询智能合约，函数：chaincodeQuery
10. 从组织1的节点0向组织2的节点0转移数据10的交易，函数：chaincodeInvoke
11. 在组织2的节点1上安装智能合约，函数：installChaincode
12. 在组织2的节点1上查询智能合约，函数：chaincodeQuery

8.3.3 执行流程
Fabric基础环境搭建完成后，End-2-End案例的运行先从network_setup.sh文件执行，执行过程中调用generateArtifacts.sh生成公私钥和证书等文件，再根据docker-compose-cli.yaml的配置内容通过docker运行zookeeper、kafka、orderer、peer和cli,最后在cli中运行script.sh文件，批量执行创建通道、加入通道、安装智能合约、实例化智能合约、执行交易和执行查询等功能，以上过程在没有错误的情况下，自动执行逐行执行，直到提示END-E2E表示成功。
执行详细流程如下：
![]()
图：详细流程图
流程说明：
1. 在e2e_cli目录执行network_setup.sh up表示开始执行，network_setup.sh down表示结束执行；
2. 执行network_setup.sh up后先判断是否存在crypto-config目录，如果不存在，则调用generateArtifacts.sh文件生成公私钥和证书；否则通过命令docker-compose -f $COMPOSE_FILE up -d开始启动Fabric网络；
3. Fabric网络启动成功后，自动执行script.sh文件，按照代码顺序，分别执行如下代码：
1) 显示start-e2e：显示将开始执行案例；
2) checkOSNAvailability：执行peer channel fetch 0 0_block.pb -o orderer.example.com:7050 -c "$ORDERER_SYSCHAN_ID" --tls --cafile $ORDERER_CA >&log.txt命令，验证排序（orderer）服务是否可用；
3) createChannel：执行peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile $ORDERER_CA >&log.txt命令创建通道；
4) joinChannel：执行peer channel join -b $CHANNEL_NAME.block >&log.txt命令四个peer节点加入到通道中；
5) updateAnchorPeers 0 1：执行peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/${CORE_PEER_LOCALMSPID}anchors.tx --tls --cafile $ORDERER_CA >&log.txt命令更新组织1的锚节点0；
6) updateAnchorPeers 0 2：执行peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/${CORE_PEER_LOCALMSPID}anchors.tx --tls --cafile $ORDERER_CA >&log.txt命令更新组织2的锚节点0；
7) installChaincode 0 1：执行peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/example02/cmd >&log.txt命令在组织1的节点0上安装智能合约；
8) installChaincode 0 2：执行peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/example02/cmd >&log.txt命令在组织2的节点0上安装智能合约；
9) instantiateChaincode 0 2：执行peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')" >&log.txt在组织2的节点0上实例化智能合约，初始化a值为100和b值为200；
10) chaincodeQuery 0 1 100：执行peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}' >&log.txt命令在组织1的节点0上查询a值，并判断是否为100；
11) chaincodeInvoke 0 1 0 2：执行peer chaincode invoke -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc $PEER_CONN_PARMS -c '{"Args":["invoke","a","b","10"]}' >&log.txt命令从a值中转称10到a值中；
12) installChaincode 1 2：执行peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/example02/cmd >&log.txt命令在组织2的节点1上安装智能合约；
13) chaincodeQuery 1 2 90：执行peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}' >&log.txt命令在组织2的节点1上查询a值，并判断是否为90；
14) chaincodeQuery 1 3 90：执行peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}' >&log.txt命令在组织3的节点1上查询a值，并判断是否为90；
15) 显示end-e2e：以上代码执行没有出现错误，则显示end-e2e表示成功执行；
8.3.4 智能合约介绍
智能合约通过Go语言编写，实现存储a和b值，并在a和b之间数据交易转移，主要包括Init（初始化）、Invoke（交易）、delete（删除）和query（查询）四个函数，具体代码如下：

# present in a fabric binary for that binary to safely participate in the
# fabric network. For instance, if a new MSP type is added, newer binaries
# might recognize and validate the signatures from this type, while older
# binaries without this support would be unable to validate those
# transactions. This could lead to different versions of the fabric binaries
# having different world states. Instead, defining a capability for a channel
# informs those binaries without this capability that they must cease
# processing transactions until they have been upgraded. For v1.0.x if any
# capabilities are defined (including a map with all capabilities turned off)
# then the v1.0.x peer will deliberately crash.
