環境構築

reset

$ docker stop $(docker ps -q)
$ docker rm $(docker ps -aq)
$ CONTRACT_IMAGE=$(docker images \| grep 'dev-peer0.org1.example.com-papercontract' \| awk '{print $3}')
$ docker rmi $CONTRACT_IMAGE

base network

$ cd basic-network/
$ ./start.sh

monitor起動

以下はずっと起動しっぱなしになる。

$ cd ../estate/configuration/cli/
$ ./monitordocker.sh net_basic

fabric-toolsの起動

hyperledgerとコミュニケーション取るためのもの

$ cd estate/configuration/cli
$ docker-compose -f docker-compose.yml up -d cliMagnetoCorp
Creating cliMagnetoCorp ... done

chaincodeのインストール

peer chaincode install を cliMagnetoCorp で実行する

$ docker exec cliMagnetoCorp peer chaincode install -n estatecontract -v 0 -p /opt/gopath/src/github.com/contract -l node
2019-06-06 01:44:32.834 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2019-06-06 01:44:32.835 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
2019-06-06 01:44:33.278 UTC [chaincodeCmd] install -> INFO 003 Installed remotely response:<status:200 payload:"OK" >

chaincodeのinstantiate

peer chaincode instantiate を cliMagnetoCorpで実施する。

docker exec cliMagnetoCorp peer chaincode instantiate -n estatecontract -v 0 -l node -c '{"Args":["org.estatenet.estate:instantiate"]}' -C mychannel -P "AND ('Org1MSP.member')"

createEstate.js 動かす

$ cd estate/application
$ npm install

wallet追加

user1

$ node addToWallet.js
done

user2

$ node addToWallet.js
done

createEstate.js実行

$ node createEstate.js
Connect to Fabric gateway.
Use network channel: mychannel.
Use org.estatenet.estate smart contract.
Submit estate issue transaction.

Process estate transaction response.
undefined estate : SCFoundation successfully created. price 50000000
Transaction complete.
Disconnect from Fabric gateway.
Estate program complete.

成功した 👍

chaincodeのinstantiate時にcompileエラー

docker exec cliMagnetoCorp peer chaincode instantiate -n papercontract -v 0 -l node -c '{"Args":["org.papernet.commercialpaper:instantiate"]}' -C mychannel -P "AND ('Org1MSP.member')"

該当の estate.js のソースを以下にかえても、まったく上のエラーと同じ。何かキャッシュが残っている？

const State = require('../ledger-api/aaaa-state.js');

dockerの全削除してみるか、、、うまくいかない
image削除しないとだめかもしれない、、、、

結局、dev-peer0.org1.example.com-estatecontract-0 を消したら大丈夫だった 👍

estateを全て取得するchaincodeが動かない。

    async findByQuery(query) {
        let iterator = await this.ctx.stub.GetQueryResult(query);

        const allResults = [];
        while (true) {
            const res = await iterator.next();

            if (res.value && res.value.value.toString()) {
                console.log(res.value.value.toString('utf8'));

                const Key = res.value.key;
                let Record;
                try {
                    Record = JSON.parse(res.value.value.toString('utf8'));
                } catch (err) {
                    console.log(err);
                    Record = res.value.value.toString('utf8');
                }
                allResults.push({ Key, Record });
            }
            if (res.done) {
                console.log('end of data');
                await iterator.close();
                console.info(allResults);
                // return JSON.stringify(allResults);
                return allResults;
            }
        }
    }

を実行すると以下エラー。

TypeError: this.ctx.stub.GetQueryResult is not a function, stack=Error: transaction returned with failure: TypeError: this.ctx.stub.GetQueryResult is not a function

GetQueryResultがないと。

とおもったら、getQueryResult になおしたらうまくいった汗
