ChainMaker

长安链搭建

  1. 创建工作目录: mkdir ${WORKDIR} && cd ${WORKDIR}
  2. 下载项目: git clone -b v2.2.0 https://git.chainmaker.org.cn/chainmaker/chainmaker-go.git
  3. 下载项目: git clone -b v2.2.0 https://git.chainmaker.org.cn/chainmaker/chainmaker-cryptogen.git
  4. 拉取镜像: docker pull chainmakerofficial/chainmaker-vm-docker-go:v2.2.0.1
  5. 编译证书: cd chainmaker-cryptogen && make
  6. 创建软链接: ln -s ${WORKDIR}/chainmaker-cryptogen ${WORKDIR}/chainmaker-go/tools
  7. 生成单链单节点证书配置文件:
cd ${WORKDIR}/chainmaker-go/scripts
./prepare.sh 1 1
# input consensus type (0-SOLO,1-TBFT(default),3-MAXBFT,4-RAFT): 0
# input log level (DEBUG|INFO(default)|WARN|ERROR): INFO
# enable docker vm (YES|NO(default))YES
tree -L 3 ../build
  1. 编译安装包:
 ./build_release.sh
tree ../build/release
  1. 解压安装包并运行:
cd ../build/release
tar zxvf chainmaker-xxxx.tar.gz
cd chainmaker-xxxx/bin && ./start.sh
  1. 查看运行情况: netstat -lptn | grep 1230

CMC命令行工具安装

  1. cd ${WORKDIR}/chainmaker-go/tools/cmc
  2. go build

合约创建

./cmc client contract user create \
--contract-name=contract_fact \
--runtime-type=DOCKER_GO \
--byte-code-path=./testdata/docker-go-demo/contract_fact.7z \
--version=1.0 \
--sdk-conf-path=./testdata/sdk_config.yml \
--admin-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.key,./testdata/crypto-config/wx-org2.chainmaker.org/user/admin1/admin1.tls.key,./testdata/crypto-config/wx-org3.chainmaker.org/user/admin1/admin1.tls.key,./testdata/crypto-config/wx-org4.chainmaker.org/user/admin1/admin1.tls.key \
--admin-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.crt,./testdata/crypto-config/wx-org2.chainmaker.org/user/admin1/admin1.tls.crt,./testdata/crypto-config/wx-org3.chainmaker.org/user/admin1/admin1.tls.crt,./testdata/crypto-config/wx-org4.chainmaker.org/user/admin1/admin1.tls.crt \
--sync-result=true \
--params="{}"

调用合约

./cmc client contract user invoke \
--contract-name=contract_fact \
--method=invoke_contract \
--sdk-conf-path=./testdata/sdk_config.yml \
--params="{\"method\":\"save\",\"file_name\":\"name007\",\"file_hash\":\"ab3456df5799b87c77e7f88\",\"time\":\"6543234\"}" \
--sync-result=true

查询合约

./cmc client contract user get \
--contract-name=contract_fact \
--method=invoke_contract \
--sdk-conf-path=./testdata/sdk_config.yml \
--params="{\"method\":\"findByFileHash\",\"file_hash\":\"ab3456df5799b87c77e7f88\"}"

Docker-Go合约开发

  1. 在目录chainmaker-contract-sdk-docker-go中编写合约
  2. 执行./buid.sh编译合约, 生成的文件存放于target目录下

Go-SDK使用教程

  1. 编写配置文件, 样例见sdk-go/client/sdk_config.yaml
  2. 确认证书crypto-config的路径
  3. 确认编译后的7z合约路径
  4. 安装, 查询, 调用合约方法见sdk-go/client/sdk_test.go文件中的示例
  5. !!!注意: QueryContract和InvokeContract中的method参数需设置为invoke_contract, 具体的方法和参数均包装在params字段中
