运行示例
- 下载示例
git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-samples
- 启动脚本
- 进入到balance-transfer目录，运行runApp.sh脚本，fabric网络以及node服务都会运行起来
cd balance-transfer
./runApp.sh
./runApp.sh执行结果
- 测试脚本
- 在另一个终端运行testAPIs.sh测试脚本，使用API来操作fabric网络，它主要做了：
- 创建channel
- 安装chaincode
- 初始化chaincode
- 执行chaincode
- 各种查询
./testAPIs.sh
- 运行结果（部分省略）
