Question

我是超级账本结构的新手，并尝试了一些实践。我正在尝试使用Fabric SDK将对等方添加并加入到通道中，但是我得到““ [[Remote.js]：错误：无法在截止日期URL：grpcs：// localhost：7088”“之前连接此错误。 / p>

我使用了通道的addPeer功能，添加后我尝试使用连接通道操作将对等连接到通道。但是在运行代码后，我得到了上面提到的错误。如果有人可以建议如何使用Fabric API添加和加入对等方。

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 ={
            name: 'peer4.org1.example.com',
            request_timeout: '5252',

        var channel =  network.getChannel();

        channel.addPeer(peer,'Org1MSP')

        }

        channel.joinChannel(request, 5252)

}

在截止期限URL：grpcs：// localhost：7088 之前无法连接->定义它正在尝试使用相应的端口连接到服务器，但是失败。似乎是服务未运行或端口未正确绑定。确保服务正常运行或启用了端口。如有任何问题，请告诉我
