fabric-go-sdk 初体验

简介

此项目是一个模拟公民身份信息链的区块链项目

github 地址： https://github.com/akkagao/citizens

使用fabric-go-sdk  搭建的一个测试环境。能完成sdk安装、初始化、调用、查询chainCode的所有功能

模拟业务场景：

1:模拟政府管理全国公民身份信息。

2:由FBI 代劳录入信息，也可以查询用户信息

解决问题

1: 各个政府部门之间信息不同步，导致公民在政府办理各种事物需要提供各种证明。比如买房要提供无犯罪证明、单身证明、本地无房产证明，社保、公积金、等等一堆证明……...

2:业务代办理证明你妈是你妈（不知道这个梗可以搜索“你妈是你妈”）。这只有生活在我天朝上国的人才能体验到的尊贵服务。

3:小孩出生录入指纹、DNA、虹膜等生物识别信息。如果小孩走失，长大后只要根据自己生物识别信息就可以找到自己的亲身父母。

启动体验

# 创建目录

mkdir$GOPATH/src/github.com/akkagao/

# 进入目录

cd$GOPATH/src/github.com/akkagao/

# 下载项目

gitclone git@github.com:akkagao/citizens.git

# 在fabric-service目录下执行

cdfabric-service

# 启动fabric服务，所有日志都会输出到 all.log 中

./start.sh  

# 然后进入web-service 目录

cdweb-service

# 使用 go run main.go命令启动gosdk项目 执行链码的安装、初始化、执行、查询等操作

go run main.go

部署流程

1. 安装软件环境

此项目在macPro环境下部署

安装git

安装golang

安装docker

安装docker-compose

以上软件安装自行google吧，教程很多。

2. 编译工具

把fabric源码下载到 $GOPATH/src/github.com/hyperledger 目录下

git clone git@github.com:hyperledger/fabric.git

切换到1.1版本（本项目使用fabirc1.1作为演示）

git checkout -b release-1.1 origin/release-1.1

生成工具包

在fabric目录$GOPATH/src/github.com/hyperledger/fabric目录下执行

make configtxgen

make cryptogen

在build/bin目录下生成 configtxgen cryptogen 文件

把上面编译好的文件放到本项目 fabric-service/bin 目录下

➜ fabric-service git:(master) ✗ tree -lbin

bin

├── configtxgen

└── cryptogen

编写配置文件

约定

本项目暂定1个组织FBI，组织有2个节点，2个用户

根域名使用 citizens.com

crypto-config.yaml 文件

使用下面命令生成 文件模版

./bin/cryptogen showtemplate > crypto-config.yaml

根据实际定义修改内容，最终结果为

OrdererOrgs:

- Name: Orderer

  Domain: citizens.com

  Specs:

- Hostname: orderer

PeerOrgs:

- Name: FBI

  Domain: fbi.citizens.com

  EnableNodeOUs: false

  Template:

    Count: 2

  Users:

    Count: 2

在fabric-service目录下生成证书目录

➜ fabric-service git:(master) ✗ ./bin/cryptogen generate --config=crypto-config.yaml

fbi.citizens.com

configtx.yaml 文件

从fabric配置文件例子中获取模版

➜ fabric-service git:(master) ✗ 

cp$GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/configtx.yaml ./

以上就是所有配置的基本流程,也可以参考fabric-service目录下的bulid.sh脚本内容

然后编写chainCode 和 调用链码的代码就可以测试了，具体参考chainCode和web-service目录中的go代码

启动体验

在fabric-service目录下执行

./start.sh  启动fabric服务，所有日志都会输出到 all.log 中

然后进入web-service 目录

使用  go run main.go命令启动gosdk项目 执行链码的安装、初始化、执行、查询等操作

以下是配置调试过程中遇到的一些错误处理方法

清理docker 网络

➜ fabric-service git:(master) ✗ docker network ls

NETWORK ID         NAME               DRIVER             SCOPE

c1f91c6c5086       bridge             bridge             local

aced91a76322       host               host               local

57502ba90162       none               null               local

➜ fabric-service git:(master) ✗ docker rm57502ba90162

使用start脚本启动

脚本会清理之前操作残留的docker 以免对当前开发环境产生影响

如果没有报错说明启动成功，然后docker ps查看所有定义的容器是否都存在
