【fabric源碼】Goland/Vscode調試Hyperledger Fabric 2.0源碼、單機網絡（傻瓜式調試）

原創 kk3909 2020-06-30 13:23

引言

  • 啓動一個peer和一個orderer
  • 使用fabric/sampleconfig下的配置文件（一個組織SampleOrg）,生成創世塊和通道配置
  • 創建通道myc,peer加入通道
  • 用fabric-sample中的fabcar作爲例子，打包、安裝、審覈、提交鏈碼，再初始化賬本，創建一輛car，查詢所有所有car。
  • 所有命令執行都使用debug模式,無需敲任何peer命令
  • 可調試鏈碼

環境

  • macOS cataline 10.15.3
  • goland 2019.3 / vscode 1.43.0
  • go 1.14
  • docker-machine 0.16.0
  • docker 19.03.5
  • ss代理

1. 準備工作

注意：$GOPATH修改成你的GOPATH路徑

1.1. 下載源碼

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

下載慢的話需要配置下代理,這裏我本地啓動了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.創建配置文件目錄

cd fabric
mkdir -p dev-network/config

1.3. 拷貝配置文件、外部構建程序、鏈碼demo

cp -r sampleconfig/* dev-network/
cp -r integration/externalbuilders dev-network/
cp -r $GOPATH/src/github.com/hyperledger/fabric-samples/chaincode $GOPATH/src/github.com/hyperledger/fabric/dev-network/

拷貝完後dev-network目錄結構如下

├── chaincode
│   ├── abac
│   ├── abstore
│   ├── fabcar
│   ├── marbles02
│   ├── marbles02_private
│   └── sacc
├── config
├── configtx.yaml
├── core.yaml
├── externalbuilders
│   ├── binary
│   └── golang
├── msp
│   ├── admincerts
│   ├── cacerts
│   ├── config.yaml
│   ├── keystore
│   ├── signcerts
│   ├── tlscacerts
│   └── tlsintermediatecerts
└── orderer.yaml

1.4.修改peer配置文件dev-network/core.yaml

找到fileSystemPath，修改存儲路徑

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

使用docker跑鏈碼配置（不支持調試chaincode）：peer會調用docker api執行構建、運行鏈碼等操作。
找到vm,修改endpoint和docker配置（請根據實際情況，修改成你自己docker配置）

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

外部跑鏈碼配置（支持調試chaincode）

chaincode:
    externalBuilders:
    - path: $GOPATH/src/github.com/hyperledger/fabric/dev-network/externalbuilders/golang
      name: external-golang
      environmentWhitelist:
      - GOPROXY
      - GOCACHE
      - GOPATH

注意：package的時候label標籤需要以-external結尾，eg:--label fabcarv1-external，如果需要修改默認的規則，請修改dev-network/externalbuilders/golang/bin/detect腳本

if [[ "$(jq -r .label "$2/metadata.json")" != *-external* ]]; then
    >&2 echo "only golang chaincode named with an '-external' suffix is supported"
    exit 1
fi

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

修改創世塊文件位置（OPT，可不修改，後面01 orderer調試配置中有環境變量ORDERER_GENERAL_GENESISMETHOD和ORDERER_GENERAL_GENESISFILE指定了創世塊的位置）

General:
    BootstrapFile: $GOPATH/src/github.com/hyperledger/fabric/dev-network/config/orderer.block

修改賬本數據目錄

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

1.6. 調試工具dlv安裝、更新(opt，僅供參考)

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

1.7. docker machine啓動(opt，僅供參考)

docker-machine start demo

啓動後需要導入環境變量

1.8. 環境變量配置(opt，僅供參考)

~/.bash_profile

export GOROOT="/usr/local/Cellar/go/1.14/libexec"
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
export GO111MODULE=auto
export GOPROXY=https://goproxy.io
eval $(docker-machine env demo)

1.9. 安裝外部構建依賴(opt，僅供參考)

brew install jq

2. 編譯configtxgen

fabric使用dep管理依賴，如果使用go mod init轉換成go.mod 會出現不能預知的錯誤（如viper版本過高，不能正確獲取key值），如果GO111MODULE=on請設置爲off或auto

export GO111MODULE=auto

執行編譯，構建這個程序主要爲了創建創世塊和通道配置

make configtxgen

3. 生成創世塊和通道配置

cd dev-netwok
# 創世塊
$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

檢查是否config目錄是否有文件生成

4.導入項目

4.1. 使用goland調試

  1. 用goland打開$GOPATH/src/github.com/hyperledger/fabric目錄，會在當前目錄下自動生成.idea目錄

  2. 修改golang項目配置

cd $GOPATH/src/github.com/hyperledger/fabric
vim .idea/workspace.xml
  1. project下添加RunManager組件（用於調試或運行peer 和orderer等相關命令）

沒問題的話，將看到下面圖中的配置

  1. 用vscode打開$GOPATH/src/github.com/hyperledger/fabric目錄
  2. 在fabric目錄下創建項目配置文件.vscode/launch.json,內容如下：

沒有問題的話，打開了調試窗口，將看到下面圖中的配置
在這裏插入圖片描述
注意：vscode的go插件默認使用go mod,須傳入GO111MODULE=auto禁用go mod ，目錄下沒有go.mod的時候，不使用go mod構建，否則會出現以下錯誤。

can't load package: cannot find module providing package github.com/hyperledger/fabric/cmd/peer: working directory is not part of a module
exit status 1
Process exiting with code: 1

5. 開始調試

依次運行01~14配置，在需要的地方設置斷點，觀察控制檯變化

  • 將配置02 peer中環境變量CORE_PEER_ADDRESS的值修改成你網卡ip地址（不能使用127.0.0.1之類的迴環地址），否則鏈碼無法連接到peer鏈碼服務
  • 將配置02 peer中環境變量GOCACHE的值修改成go env GOCACHE獲取的值，否則externalbuilder無法build
  • 05 chaincode package 有兩個配置，需要調試鏈碼請跑externalbuilder
  • 執行06 chaincode install或07 chaincode queryinstalled 後需記錄下Package ID，執行08 chaincode approve替換package-id的值,鏈碼和標籤修改都會導致package-id發生變化
  • 如果使用docker跑鏈碼，執行10 chaincode commit後，執行docker ps查看鏈碼容器是否啓動，如果沒有啓動鏈碼無法調用；如果使用externalbuilder跑鏈碼，執行ps -ef | grep fabcarv1-external檢查鏈碼進程是否啓動

6. debug chaincode(僅針對externalBuilder模式)

  1. 配置修改
    修改15 chaincode debug fabcar配置中參數
    環境變量CORE_CHAINCODE_ID_NAME爲package-id
    參數-peer.address參數指定peer的鏈碼服務監聽地址。

  2. 下載依賴

 cd chaincode/fabcar/go 
 go get -t github.com/hyperledger/fabric-contract-api-go/contractapi
  1. 殺掉peer啓動的chaincode進程（下一步啓動成我們自己的chaincode進程）
ps -ef | grep fabcarv1-external | grep -v grep | awk '{print $2}'|xargs kill -9
  1. 打好斷點，啓動調試程序15
  2. 啓動配置13或14調用chaincode ，檢查斷點是否有效
