HyperLedger结构链代码未更新 [英] HyperLedger fabric chaincode not updated

问题描述

我正在尝试遵循此示例Hyperledger Fabric代码: https ://github.com/hyperledger/education/tree/master/LFS171x/fabric-material

I am trying to follow along this sample Hyperledger Fabric code: https://github.com/hyperledger/education/tree/master/LFS171x/fabric-material

最初，我用go文件chaincode/tuna-app/test.go替换了chaincode/tuna-app/tuna-chaincode.go. test.go的更改仅在于我们通过其initLedger函数调用在分类帐中初始化的内容.它运行良好，不需要在tuna-app/.startFabric.sh中进行任何更改.

Initially I replaced chaincode/tuna-app/tuna-chaincode.go with my go file chaincode/tuna-app/test.go. test.go had changes just in what we initialize in the ledger through its initLedger function call. It worked fine, with no changes required in tuna-app/.startFabric.sh.

现在，当我再次尝试通过其initLedger函数调用更改分类帐时，它没有发生.即使我评论了函数本身，它仍然显示了分类帐的旧内容.

Now when I again try to change the ledger through its initLedger function call, its not happening. Even if I comment the function itself, it still shows the old content of the ledger.

如何通过可见的更改更新链码?

How do I update my chaincode with visible changes?

startFabric.sh包含以下代码:

startFabric.sh contains the following code:

set -e

# don't rewrite paths for Windows Git Bash users
export MSYS_NO_PATHCONV=1

starttime=$(date +%s)

if [ ! -d ~/.hfc-key-store/ ]; then
    mkdir ~/.hfc-key-store/
fi

# launch network; create channel and join peer to channel
cd ../basic-network
./start.sh

# Now launch the CLI container in order to install, instantiate chaincode
# and prime the ledger with our 10 tuna catches
docker-compose -f ./docker-compose.yml up -d cli

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[e-mail]/msp" cli peer chaincode install -n tuna-app -v 1.0 -p github.com/test-app
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[e-mail]/msp" cli peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n tuna-app -v 1.0 -c '{"Args":[""]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
sleep 10
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[e-mail]/msp" cli peer chaincode invoke -o orderer.example.com:7050 -C mychannel -n tuna-app -c '{"function":"initLedger","Args":[""]}'

printf "\nTotal execution time : $(($(date +%s) - starttime)) secs ...\n\n"
printf "\nStart with the registerAdmin.js, then registerUser.js, then server.js\n\n"

我尝试在对等链码实例化之后添加以下行:

I tried by adding the following line after peer chaincode instantiate :

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[e-mail]/msp" cli peer chaincode upgrade -o orderer.example.com:7050 -C mychannel -n tuna-app -c '{"function":"initLedger","Args":[""]}'

但是会出现以下错误:

Error: Chaincode version is not provided for upgrade

当我将升级声明更改为:

When I change upgrade statement to:

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[e-mail]/msp" cli peer chaincode upgrade -o orderer.example.com:7050 -C mychannel -n tuna-app -v 1.0 -c '{"function":"initLedger","Args":[""]}'

错误更改为:

Error: Error endorsing chaincode: rpc error: code = Unknown desc = chaincode error (status: 500, message: version already exists for chaincode with name 'tuna-app')

推荐答案

要反映链式代码中的更改，请执行以下步骤: 1.停止所有容器

To make the changes in the chaincode made reflect, following steps were taken: 1. Stop all the containers

docker stop $(docker ps -aq)

1. 删除所有容器

docker rm -f $(docker ps -aq)

1. 运行docker images时查找以下图像 输出之一将是其他超级分类帐二进制图像中的输出.

1. Find the following image when you run docker images One of the output will be this among the other hyperledger binary images.

REPOSITORY TAG, IMAGE ID, CREATED, SIZE: dev-peer0.org1.example.com-tuna-app-1.0-b58eb592ed6ced10f52cc063bda0c303a4272089a3f9a99000d921f94b9bae9b, latest, 0919d7c15f0a, 3 minutes ago, 172MB

使用以下命令删除它:

docker rmi 0919d7c15f0a

使用./startFabric.sh、npm install，节点registerAdmin.js，节点registerUser.js和节点server.js再次运行结构.它应该可以工作

Run the fabric again using ./startFabric.sh, npm install, node registerAdmin.js, node registerUser.js and node server.js. It should work
