提交交易失败：错误：没有合适的节点可用于初始化

Question

我正在运行我的区块链项目，该项目是使用区块链的选举系统，使用超级账本结构和 IBM 区块链平台 VSCode 扩展（在本地运行我的网络）。我成功运行连接到本地结构，并且我的网关运行成功（附图片）。此外，peer、orderer、certificate authority 的所有 docker 容器都在运行（附图片）。

connected to local fabric and gateway

all docker containers running successfuly

我面临的问题是（在连接到本地结构和网关之后）我使用命令“node invoke.js”运行invoke.js 文件时遇到上述错误。以下图片链接显示了我如何运行 invoke.js

以下是我的 config.json 文件代码

以下是我的invoke.js文件完整代码

//Import Hyperledger Fabric 1.4 programming model - fabric-network
'use strict';

const { FileSystemWallet, Gateway } = require('fabric-network');
const path = require('path');
const fs = require('fs');

//connect to the config file
const configPath = path.join(process.cwd(), './config.json');
const configJSON = fs.readFileSync(configPath, 'utf8');
const config = JSON.parse(configJSON);

// connect to the connection file
const ccpPath = path.join(process.cwd(), './ibpConnection.json');
const ccpJSON = fs.readFileSync(ccpPath, 'utf8');
const connectionProfile = JSON.parse(ccpJSON);

// A wallet stores a collection of identities for use
const walletPath = path.join(process.cwd(), './wallet');
const wallet = new FileSystemWallet(walletPath);
console.log(`Wallet path: ${walletPath}`);

const peerIdentity = 'admin';

async function queryAll() {
  
  try {

    let response;

    // Check to see if we've already enrolled the user.
    const userExists = await wallet.exists(peerIdentity);
    if (!userExists) {
      console.log('An identity for the user ' + peerIdentity + ' does not exist in the wallet');
      console.log('Run the registerUser.js application before retrying');
      response.error = 'An identity for the user ' + peerIdentity + ' does not exist in the wallet. Register ' + peerIdentity + ' first';
      return response;
    }

    //connect to Fabric Network, but starting a new gateway
    const gateway = new Gateway();

    //use our config file, our peerIdentity, and our discovery options to connect to Fabric network.
    await gateway.connect(connectionProfile, { wallet, identity: peerIdentity, discovery: config.gatewayDiscovery });

    //connect to our channel that has been created on IBM Blockchain Platform
    const network = await gateway.getNetwork('mychannel');

    //connect to our insurance contract that has been installed / instantiated on IBM Blockchain Platform
    const contract = await network.getContract('voteChainDemo'); 
    //submit transaction to the smart contract that is installed / instnatiated on the peers
    console.log('calling contract.evaluateTransaction, with args');
    response = await contract.submitTransaction('queryAll');
    response = JSON.parse(response.toString());
    console.log(`response from evaluateTransaction: ${(response)}`)
   

    console.log('Transaction has been submitted');

    // Disconnect from the gateway.
    await gateway.disconnect();

  } catch (error) {
    console.error(`Failed to submit transaction: ${error}`);
  }
}
// let args = ["V1"]
// args = args.toString();
queryAll();

当我查看 peer0.org1.example.com 的 docker 容器日志时，我看到了以下日志

Answer 1

在我的项目中，几乎和你一样，我没有在我的连接配置文件中指定orderers。我不确定您的场景是否需要它。

此外，我认为问题是由您在ibpconnection.jsonfile 中指定的不正确的网址引起的。

orderers 应该有"url": "grpcs://173.193.112.109:7050"

与

peers 应该有"url": "grpcs://173.193.112.109:17091"

希望这将修复错误。祝你好运！！！！
