Fabric sdk go sample

environment:
golang v1.13
fabric v1.4.2

基于 fabric 1.4.2 fabric-samples/first-network启动的网络
通过使用 fabric-sdk-go 的客户端, 使用链码的例子 声明：参考了jxu86/fabric-sdk-go-sample代码库的相关文件

目录:

• app: main.go
• 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

   先把 chaincode 目录下的链码，复制到 fabric-samples/chaincode/chaincode_example02/go/ 
   再进入 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 vendor
   

4. 运行客户端程序go run main.go

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