Running environment

ubuntu 22.04

golang 1.18

fabric 2.4.3

docker-compose

IPFS

(The golang version cannot be too high. It is found that versions above 1.18 will cause fabric-sdk-go compilation to fail.)

steps

1. Deploy the fabric-sample test network

1.1 clone the repository

git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-sample
git checkout v2.4.3

1.2 download binary files

wget https://github.com/hyperledger/fabric/releases/download/v2.4.3/hyperledger-fabric-linux-amd64-2.4.3.tar.gz
wget https://github.com/hyperledger/fabric-ca/releases/download/v1.5.3/hyperledger-fabric-ca-linux-amd64-1.5.3.tar.gz
tar xvzf hyperledger-fabric-linux-amd64-2.4.3.tar.gz
tar xvzf hyperledger-fabric-ca-linux-amd64-1.5.3.tar.gz
cd bin
export PATH=${PWD}:$PATH
cd ../

1.3 download docker images

docker pull hyperledger/fabric-peer:2.4.3
docker pull hyperledger/fabric-orderer:2.4.3
docker pull hyperledger/fabric-ccenv:2.4.3
docker pull hyperledger/fabric-tools:2.4.3
docker pull hyperledger/fabric-baseos:2.4.3
docker pull hyperledger/fabric-ca:1.5.3

docker tag hyperledger/fabric-peer:2.4.3 hyperledger/fabric-peer
docker tag hyperledger/fabric-peer:2.4.3 hyperledger/fabric-peer:2.4
docker tag hyperledger/fabric-orderer:2.4.3 hyperledger/fabric-orderer
docker tag hyperledger/fabric-orderer:2.4.3 hyperledger/fabric-orderer:2.4
docker tag hyperledger/fabric-ccenv:2.4.3 hyperledger/fabric-ccenv
docker tag hyperledger/fabric-ccenv:2.4.3 hyperledger/fabric-ccenv:2.4
docker tag hyperledger/fabric-tools:2.4.3 hyperledger/fabric-tools
docker tag hyperledger/fabric-tools:2.4.3 hyperledger/fabric-tools:2.4
docker tag hyperledger/fabric-baseos:2.4.3 hyperledger/fabric-baseos
docker tag hyperledger/fabric-baseos:2.4.3 hyperledger/fabric-baseos:2.4
docker tag hyperledger/fabric-ca:1.5.3 hyperledger/fabric-ca
docker tag hyperledger/fabric-ca:1.5.3 hyperledger/fabric-ca:1.5

1.3 start the fabric test network

cd test-network
./network.sh down
./network.sh up

1.4 create the channel

./network.sh createChannel

you should see:

2. Deploy the DTModeling contract

2.1 copy repository contract folder to test-network

cp -r {repo_path}/CP-ABE-Blockchain/contract .
cd contract/
go mod vendor

2.2 deploy the contract

./network.sh deployCC -ccn DTModeling -ccp contract -ccl go

3. Test if can connect to fabric by SDK

3.1 copy the fabric certificates to config folder

cd CP-ABE-Blockchain/config
cp -r {fabric-sample-path}/test-network/organizations/* .

3.2 test if can connect to fabric

cd ../
go test -v ./test/ -run=TestGetBlockData

4. Start IPFS

(If you don't want to start IPFS, you need to change the shareFileToIpfs method in device.go)

4.1 download IPFS

wget https://dist.ipfs.tech/kubo/v0.29.0/kubo_v0.29.0_linux-amd64.tar.gz
tar -xvzf kubo_v0.29.0_linux-amd64.tar.gz
cd kubo
./ipfs init
./ipfs daemon

5. Run code

4.1 start the AS server

go run main.go

4.2 run the CP_ABE_Blockchain_test

go test -v test/CP_ABE_Blockchain_test.go
