fabric hyledger 开发模式

fabric hyledger 开发模式 http://hyperledger-fabric.readthedocs.io/en/latest/chaincode4ade.html

准备：

//下载go 相关库

go get -u --tags nopkcs11 github.com/hyperledger/fabric/core/chaincode/shim
go build --tags nopkcs11

//下载sample

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

//下载 Platform-specific Binaries

curl -sSL https://goo.gl/iX9dek | bash （被墙）

//开发时要启动 3个 terminal，并执行相应命令

1.Terminal: 启动 docker 运行环境

cd chaincode-docker-devmode
sudo docker-compose -f docker-compose-simple.yaml up

2.Terminal - Build & start the chaincode, 编译 和启动 合约

docker exec -it chaincode bash
cd sacc
go build  //编译
//启动，在调用合约时，这里必须一直保持 开启状态
CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=mycc:0 ./sacc  

3.Terminal - Use the chaincode

docker exec -it cli bash

peer chaincode install -p chaincodedev/chaincode/sacc -n mycc -v 0
peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","100"]}' -C myc

//查询
peer chaincode query -n mycc -c '{"Args":["query","a"]}' -C myc

//执行
peer chaincode invoke -n mycc -c '{"Args":["set","a","333"]}' -C myc
