运行示例

---

1. 下载示例

git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-samples

2. 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

3. 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）

POST request Create channel  ...

{"success":true,"message":"Channel 'mychannel' created Successfully"}

POST request Join channel on Org1

{"success":true,"message":"Successfully joined peers in organization Org1 to the channel:mychannel"}

POST request Join channel on Org2

{"success":true,"message":"Successfully joined peers in organization Org2 to the channel:mychannel"}

POST Install chaincode on Org1

{"success":true,"message":"Successfully install chaincode"}

POST Install chaincode on Org2

{"success":true,"message":"Successfully install chaincode"}

POST instantiate chaincode on peer1 of Org1

{"success":true,"message":"Successfully instantiate chaingcode in organization Org1 to the channel 'mychannel'"}

POST invoke chaincode on peers of Org1

Transacton ID is 2eded4ef539d54b6822ba214788c5ae1515985d9c3628fdd259f5e0ab53582e5
