20.1. 链码开发与测试

20.1.1. Docker 开发环境

环境安装

安装 fabric-samples

			
git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-samples
			
			
			
[root@localhost ~]# cd fabric-samples/chaincode-docker-devmode/
[root@localhost chaincode-docker-devmode]# mkdir chaincode
[root@localhost chaincode-docker-devmode]# cp docker-compose-simple.yaml docker-compose.yaml
[root@localhost chaincode-docker-devmode]# sed -i "s|./chaincode|./chaincode|g" docker-compose.yaml

chaincode 目录是开发目录

清理镜像和容器

		
docker rm -f $(docker ps -q -a)
docker rmi -f $(docker images -q)

安装所需镜像

		
[root@localhost chaincode-docker-devmode]# curl -s https://raw.githubusercontent.com/oscm/shell/master/blockchain/hyperledger/fabric/1.1.0/all-in-one.sh | bash		

[root@localhost chaincode-docker-devmode]# docker images

20.1.3. 启动容器部署chaincode

		
[root@localhost chaincode-docker-devmode]# docker-compose up -d

进入容器

		
[root@localhost ~]# docker exec -it chaincode bash
root@78d23b3b2b37:/opt/gopath/src/chaincode#

编译并部署chaincode

		
root@78d23b3b2b37:/opt/gopath/src/chaincode# ls
chaincode_example02.go
root@78d23b3b2b37:/opt/gopath/src/chaincode# go build chaincode_example02.go 
root@78d23b3b2b37:/opt/gopath/src/chaincode#

进入 chaincode 容器启动 chaincode 程序。

		
[root@localhost ~]# docker exec -it chaincode bash
root@78d23b3b2b37:/opt/gopath/src/chaincode# ls
chaincode_example02.go
root@78d23b3b2b37:/opt/gopath/src/chaincode# go build chaincode_example02.go 
root@78d23b3b2b37:/opt/gopath/src/chaincode# CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=chaincode_example02:1.0 ./chaincode_example02 
2018-02-17 04:07:31.156 UTC [shim] SetupChaincodeLogging -> INFO 001 Chaincode log level not provided; defaulting to: INFO
2018-02-17 04:07:31.156 UTC [shim] SetupChaincodeLogging -> INFO 002 Chaincode (build level: ) starting up ...

CORE_CHAINCODE_ID_NAME=chaincode_example02:1.0 记住这里的配置，下面会用到

20.1.4. 手工测试

进入 cli 容器

		
[root@localhost ~]# docker exec -it cli bash
root@33dcacfb6f81:/opt/gopath/src/chaincodedev#		
		
			
		
root@33dcacfb6f81:/opt/gopath/src/chaincodedev# peer chaincode install -v 1.0 -n chaincode_example02 -p chaincodedev/chaincode

20.1.6. 在宿主主机上编译合约

编译 chaincode 可以在 docker 容器中进行，也可以在 docker 外面进行。方法如下：

安装依赖的库文件

			
yum install libtool-ltdl-devel
go get github.com/hyperledger/fabric

编译合约文件

			
[root@localhost ~]# cd ~/netkiller/chaincode/chaincode_example02/
[root@localhost chaincode_example02]#

[root@localhost chaincode_example02]# go build chaincode_example02.go 

[root@localhost chaincode_example02]# ls
chaincode_example02  chaincode_example02.go  chaincode_example02_test.go
[提示]提示

由于 docker 容器中没有 vim/nano 命令，无法编译 .go 文件，所以在宿主主机编译更为方便。

20.1.7. 链码升级

已经实例化的链码如果需要更新，可以通过 upgrade 升级。

		
peer chaincode upgrade -o orderer.example.com:7050 -C mychannel -n token4 -v 1.1 -c '{"Args":[""]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

操作演示

		
[root@localhost token]# docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp" cli peer chaincode upgrade -o orderer.example.com:7050 -C mychannel -n token4 -v 1.1 -c '{"Args":[""]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
