fabric-go-sdk 学习

抽空发布一些实用干货鸭

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 -l bin
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: OrdererDomain: citizens.comSpecs:- Hostname: orderer
PeerOrgs:- Name: FBIDomain: fbi.citizens.comEnableNodeOUs: falseTemplate:Count: 2Users: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 ./

生成order创世区块锚节点配置文件

mkdir artifacts

./bin/configtxgen --profile CitizensGenesis -outputBlock ./artifacts/orderer.genesis.block
// 生成channel初始块
./bin/configtxgen --profile CitizensChannel -outputCreateChannelTx ./artifacts/citizens.tx -channelID citizens
//创建锚节点更新文件
./bin/configtxgen --profile CitizensChannel -outputAnchorPeersUpdate ./artifacts/FBImspanchors.tx -channelID citizens -asOrg FBIMSP

生成channel初始块

channel 名字为 citizens

命令：
./bin/configtxgen --profile CitizensChain -outputCreateChannelTx ./artifacts/citizens.tx -channelID citizens---------------------------------执行结果----------------------------------------------

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 rm 57502ba90162

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

4： ca启动失败

FABRIC_CA_SERVER_TLS_KEYFILE 配置没有修改完全 _sk 文件没有替换完

5: go build 报错

fabric-sdk-go 版本不对切换成 v1.0.0-alpha4 版本

../../../hyperledger/fabric-sdk-go/third_party/github.com/hyperledger/fabric/protos/orderer/configuration.pb.go:56:35: undefined: proto.InternalMessageInfo

6: go启动失败

OrgName 必须和configtx.yaml文件中的 Organizations定义的peer节点名称一致

Unable to initialize the Fabric SDK: failed to create channel management client from Admin identity: failed to create resmgmt client due to context error: invalid options to create identity, invalid org name

7: go 启动失败

config.yaml 修改为(url 值)，修改后需要重启docker

orderers:orderer.ebbyte.com:url: 127.0.0.1:7050

报错信息：

Unable to initialize the Fabric SDK: failed to save channel: create channel failed: SendEnvelope failed: calling orderer 'orderer.ebbyte.com:7050' failed: Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: readset expected key [Group]  /Channel/Application at version 0, but got version 1

8:go启动失败

config.yaml 文件中8151 端口写错了应该是8050

go程序中所有写了 resmgmt.WithTargetEndpoints(“peer0.akka.ebbyte.com”)) 的地方确认域名是否是 org pee0的域名

重新生成证书

docker images 查看所有的iamge 如果有 network-peer0-org-domain 这样的容器用docker rmi 删除一次

确认chaincode 代码所在目录名称为chaincode 并且代码package 为main go build 是否可以直接编译出二进制文件

[fabsdk/fab] 2018/08/21 13:46:12 UTC - peer.(*peerEndorser).sendProposal -> ERRO process proposal failed [rpc error: code = Unknown desc = error starting container: API error (400): {"message":"OCI runtime create failed: container_linux.go:348: starting container process caused \"exec: \\\"chaincode\\\": executable file not found in $PATH\": unknown"}
