Question

我当前正在使用IBM Blockchain Platform 2.0。我正在使用fabric-network 1.4.0和fabric-client 1.4.0连接到它。

当我从机器上的简单node.js脚本监听事件时，它运行得很好。这是示例脚本：

const ccpPath = path.resolve('C:/Users/FlorianCastelain/Documents/GitHub/blockchain-code/node-red/fabric-server/config/org1/ibp2/user1/connection.json');
const ccp = JSON.parse(fs.readFileSync(ccpPath, 'utf8'));


const walletPath = path.resolve('C:/Users/FlorianCastelain/Documents/GitHub/blockchain-code/IBP2/CHAINCODE/public-resource/profile/wallet');
const wallet = new FileSystemWallet(walletPath);


const gateway = new Gateway();
const options = { wallet, identity: 'user1', discovery: { enabled: true, asLocalhost: false } };
await gateway.connect(ccp, options);

const network = await gateway.getNetwork('CHANNELNAME');

const contract = network.getContract('CCNAME');

const channel = network.getChannel();

const eventHub = channel.newChannelEventHub('IP:PORT');
let event = eventHub.registerChaincodeEvent('CCNAME', 'EVENTREGEX', (event, number, txid, status) => {
    console.log(event);
    console.log(event.payload.toString());
    console.log(number);
}, (error) => {
    console.log(error);
}, { startBlock: 0 });
eventHub.connect(true);

但是，我的目标是将此代码包含在节点红色的节点中（请检查here。

有点上下文：当前这些节点不处理发现，这可能是需要的。我的工作目的是将其包含在这些节点中。

结果，我试图将上面的代码插入到我的节点代码中，该代码提供了以下内容：（相同的代码，它只是一个复制/粘贴）

else if (actionType === 'event') {
  node.log('EVENT');
  const ccPath = path.resolve('C:/Users/FlorianCastelain/Documents/GitHub/blockchain-code/node-red/fabric-server/config/org1/ibp2/user1/connection.json');
  const ccp = JSON.parse(fs.readFileSync(ccPath, 'utf8'));
  const walletPath = path.resolve('C:/Users/FlorianCastelain/Documents/GitHub/blockchain-code/IBP2/CHAINCODE/public-resource/profile/wallet');
  const wallet = new FileSystemWallet(walletPath);

  const gateway = new Gateway();
  const options = { wallet, identity: 'user1', discovery: { enabled: true, asLocalHost: false } };
  await gateway.connect(ccp, options);
  const network = await gateway.getNetwork('CHANEL NAME');
  const channel = network.getChannel();
  const eventHub = channel.newChannelEventHub('IP:PORT');
  let event = eventHub.registerChaincodeEvent('CCNAME', 'REGEX', (event, number, txid, status) => {
  console.log(event);
    console.log(event.payload.toString());
    console.log(number);
  }, (error) => {
    console.log(error);
  }, { startBlock: 0 });
  eventHub.connect(true);

  // const networkInfo = await connect(identityName, node.connection.discoveryEnabled, node.connection.discoveryAsLocalhost, channelName, contractName, node);
  // const channel = networkInfo.network.getChannel();
  // await subscribeToEvent(channel, contractName, msg.payload.peerName, msg.payload.startBlock,
  //     msg.payload.endBlock, msg.payload.timeout, msg.payload.eventName, node, msg);
} else if

它会产生以下错误：

{ Error: 14 UNAVAILABLE: Connect Failed

我在两个“环境”上都检查了fabric-network版本，它是1.4.0

有人知道什么可能是不同的，和/或是什么导致此错误的线索吗？

编辑：

在测试软件包时，通过npm install PATH而不是使用npm link将其链接到node-red时，出现以下错误：

编辑：有关HLF日志的更多信息。您可以找到整个日志here

出于安全性考虑，除本地主机地址外，所有地址均已更改为ADDRESS或ADDRESS:PORT（取决于所写内容）。

使用发现时的当前默认值（1.4.0-1.4.4）用于将所有返回的IP地址转换为本地主机。您需要明确禁用它。在您的代码中，我看到您已经尝试过，但是属性名称略有错误。它应该是FROM mcr.microsoft.com/dotnet/core/sdk:2.1 AS build WORKDIR /opt/project_name COPY project_name/project_name.csproj project_name/project_name.csproj RUN dotnet restore project_name/project_name.csproj COPY project_name.UnitTests/project_name.UnitTests.csproj project_name.UnitTests/project_name.UnitTests.csproj RUN dotnet restore project_name.UnitTests/project_name.UnitTests.csproj COPY . .
