如何在超级账本中将对等方添加到现有网络中

Question

我是hyperledger fabric的新手，正在尝试一些操作。我正试图使用fabric SDK将对等方添加并加入到通道中，但我得到了"[Remote.js]：错误：未能在截止日期前连接URL:grpcs://localhost:7088"此错误。

我使用了通道的addPeer功能，添加后我尝试使用加入通道操作加入对等通道。但在运行代码后，我出现了上面提到的错误。如果有人可以建议如何使用结构API添加和加入对等体。

import { FileSystemWallet, Gateway } from 'fabric-network';
import * as path from 'path';
import { Peer } from 'fabric-client';
import { request } from 'https';
const ccpPath = path.resolve(__dirname, '..', '..', '..', 'first-network', 'connection-org1.json');
async function main() {
try {
identities.
const walletPath = path.join(process.cwd(), 'wallet');
const wallet = new FileSystemWallet(walletPath);
console.log(`Wallet path: ${walletPath}`);
// Check to see if we've already enrolled the user.
const userExists = await wallet.exists('user1');
if (!userExists) {
console.log('An identity for the user "user1" does not exist in the wallet');
console.log('Run the registerUser.ts application before retrying');
return;
}

const gateway = new Gateway();
await gateway.connect(ccpPath, { wallet, identity: 'user1', discovery: { enabled: true, asLocalhost: true } });
// Get the network (channel) our contract is deployed to.
const network = await gateway.getNetwork('mychannel');
var  opts ={

var request ={

}

Answer 1

未能在截止日期前连接URL：grpcs://localhost:7088-->定义它试图用相应的端口连接到服务器，但失败了。似乎是服务没有运行或端口没有正确绑定。请确保服务正常运行或端口已启用。如果有任何问题，请告诉我
