Fabric sdk go sample

基于 fabric-samples/first-network启动的网络,通过使用 fabric-sdk-go 来操作链码的例子

environment:
golang v1.13.4 fabric v1.4.2 fabric-samples v1.4.2

images:
hyperledger/fabric-peer:1.4.2 hyperledger/fabric-orderer:1.4.2 hyperledger/fabric-tools:1.4.2 hyperledger /fabric-ccenv:1.4.2 hyperledger/fabric-baseos:amd64-0.4.15

目录:

• app: main.go，测试的主程序
• binaries: 二进制文件夹，需要将所有的二进制文件拷贝到 ***/fabric-samples/bin/ 目录下, 并在$PATH 变量中添加 ***/fabric-samples/bin/
• chaincode: 链码
• cli: 链码调用代码封装
• config: fabric sdk 与区块链交互配置

Quick start

1. 启动fabric网络

   进入 fabric-samples/first-network 
   ./byfn.sh up
   

2. 配置config.yaml

   path: ***/fabric-samples/first-network/crypto-config
   *** 改为自己的相关目录
   

3. 依赖包的安装

   cd fabric-sdk-go-sample
   go mod download
   

4. 运行客户端程序go run main.go

   [root@jc chaincode]# cd app
   [root@jc chaincode]# go run main.go
