【fabric源码】vscode调试Hyperledger Fabric 1.4源码、单机网络

注意：Fabric 2.0已发布，请参考这篇文章 【fabric源码】Goland/Vscode调试Hyperledger Fabric 2.0源码、单机网络（傻瓜式调试）

引言

启动一个peer和一个node，用example02作为例子，安装、初始化、调用、查询链码。

环境准备

• macOS Mojave 10.14
• vscode 1.42.0
• golang 1.12.6
• docker-machine 0.16.0

下载源码

cd $GOPATH/src/github.com/hyperledger/
git clone https://github.com/hyperledger/fabric.git
git checkout release-1.4
git clone https://github.com/hyperledger/fabric-samples

配置host

127.0.0.1 peer
127.0.0.1 orderer

创建peer和order配置

1.在fabric项目下创建dev-network目录
2.将fabric项目下sampleconfig文件夹下的所有文件复制到 dev-network
3.修改 core.yaml中fileSystemPath = $GOPATH/src/github.com/hyperledger/fabric/dev-network/production/peer
4.修改 orderer.yaml中 Location =$GOPATH/src/github.com/hyperledger/fabric/dev-network/production/orderer
5.在 dev-network新建 config目录，并复制fabric-samples项目中的chaincode-docker-devmode下的myc.tx和 orderer.block文件到config目录中

注意修改GOPATH

修改调试配置（.vscode/launch.json），并启动调试

• 切换到调试窗口，在需要跟踪的地方打好断点
• 依次运行order 、peer、channel create 、channel join、chaincode install、run chaincode example02、chaincode instantiate、chaincode invoke、chaincode query
• 观察debug控制台和terminal变化
