【fabric源码】Goland调试Hyperledger Fabric 2.0源码、单机网络

引言

  • 启动一个peer和一个orderer
  • 创建通道myc,加入通道
  • 用fabric-sample中的fabcar作为例子，打包、安装、审核、提交密链码，再初始化账本，创建一辆car，查询所有所有car。
  • 所有命令执行都使用debug模式

环境

  • macOS cataline 10.15.3
  • goland 2019.3
  • go 1.14
  • docker-machine 0.16.0
  • ss代理

1. 准备工作

注意：$GOPATH修改成你的GOPATH路径

1.1. 下载源码

cd $GOPATH/src/github.com/hyperledger/
git clone https://github.com/hyperledger/fabric.git
git checkout v2.0.1
git clone https://github.com/hyperledger/fabric-samples

下载慢的话需要配置下代理,这里我本地启动了ss代理

git config --global http.proxy socks5://127.0.0.1:1080
git config --global http.sslVerify false
git config --global https.proxy socks5://127.0.0.1:1080

取消代理

git config --global --unset http.proxy
git config --global --unset http.sslVerify 
git config --global --unset https.proxy

1.2.创建配置文件目录

cd fabric
mkdir -p dev-network/config

1.3. 拷贝配置文件

cp -r sampleconfig/* dev-network/

拷贝完后目录结构如下

dev-network
├── config
├── configtx.yaml
├── core.yaml
├── msp
├── orderer.yaml

1.4.修改peer配置文件dev-network/core.yaml

找到fileSystemPath

peer:
     fileSystemPath: $GOPATH/src/github.com/hyperledger/fabric/dev-network/production/peer

这里使用docker跑链码，fabric会调用docker api执行构建、运行链码等操作。找到vm,修改endpoint和docker配置，修改成你自己docker配置(endpointg和tls)

vm:
    endpoint: tcp://192.168.99.100:2376
    docker:
        tls:
            enabled: true
            ca:
                file: /Users/USER/.docker/machine/machines/demo/ca.pem
            cert:
                file: /Users/USER/.docker/machine/machines/demo/cert.pem
            key:
                file: /Users/USER/.docker/machine/machines/demo/key.pem

1.5.修改orderer配置文件dev-network/orderer.yaml

FileLedger:
    Location: $GOPATH/src/github.com/hyperledger/fabric/dev-network/production/orderer

1.6. 调试工具dlv安装、更新

xcode-select --install
go get -u github.com/go-delve/delve/cmd/dlv
sudo /usr/sbin/DevToolsSecurity -enable

2. 编译configtxgen

fabric没有使用go mod管理依赖，如果转换成go mod 会出现很多错误，如果GO111MODULE=on请设置为off或auto

export GO111MODULE=auto

执行编译，构建这个程序主要为了创建创世块和通道配置

make configtxgen

3. 生成创世块和通道配置

检查是否config目录是否有文件生成

cd dev-netwok
# 创世块
$GOPATH/src/github.com/hyperledger/fabric/build/bin/configtxgen -profile SampleDevModeSolo -channelID sys-channel -outputBlock ./config/orderer.block
# 通道配置
$GOPATH/src/github.com/hyperledger/fabric/build/bin/configtxgen -profile SampleSingleMSPChannel -outputCreateChannelTx ./config/myc.tx -channelID myc

4. 导入项目

直接用goland打开$GOPATH/src/github.com/hyperledger/fabric目录，会在当前目录下自动生成.idea目录

5. 导入调试配置

修改golang项目配置

cd $GOPATH/src/github.com/hyperledger/fabric
vim .idea/workspace.xml

project下添加RunManager组件（用于调试或运行peer 和orderer相关命令）

  <component name="RunManager" selected="Go Build.14 chaincode  fabcar QueryAllCars">

6. 开始调试

依次运行01~14配置，在需要的地方设置断点，观察控制台变化

  • 将配置“02 peer"中环境变量CORE_PEER_ADDRESS的值修改成你网卡ip地址，否则链码在容器里无法连接到链码服务
  • 05步中–path参数为你的链码路径
  • 执行06步或07步 后记录下Package ID，第8步 approve时需要修改package-id参数
  • 执行10步后，执行docker ps查看链码容器是否启动
