使用Hyperledger Fabric Node JS创建通道时出错

Question

我试图用Fabric SDK创建一个通道node.js.当我通过bash命令创建通道时，我没有问题（您可以看到下面的代码），但是当我使用node.jsSDK时，我遇到了一些错误。我正在使用TLS和客户端身份验证。我无法意识到错误意味着什么以及如何解决它。任何帮助都将不胜感激。

节点JS代码创建通道，在主机上执行：

var Fabric_Client = require('fabric-client');
var fs=require('fs');
var fabric_client = new Fabric_Client();

// Obtain tls cert and key from client.
let clientcert = fs.readFileSync('/home/rosalva40/Documentos/Own2/Own/data/tls/peer1-org1-cli-client.crt');
let clientkey = fs.readFileSync('/home/rosalva40/Documentos/Own2/Own/data/tls/peer1-org1-cli-client.key');
fabric_client.setTlsClientCertAndKey(clientcert.toString(),clientkey.toString())



//Orderer configuration
let pem1 = fs.readFileSync('/home/rosalva40/Documentos/Own2/Own/data/org0-ca-chain.pem');
const connectionopts = {
    pem: pem1.toString()
};
var order = fabric_client.newOrderer('grpcs://localhost:9101', connectionopts)


//setup identity admin
let cert = fs.readFileSync('/home/rosalva40/Documentos/Own2/Own/data/orgs/org1/admin/msp/signcerts/cert.pem');
let pk = fs.readFileSync('/home/rosalva40/Documentos/Own2/Own/data/orgs/org1/admin/msp/keystore/b17b8a06b4928a037e621cc784cac4f8a4913087c95c68162ecae6189993a1fa_sk');
const  mspid = 'org1MSP';
fabric_client.setAdminSigningIdentity(pk, cert, mspid);


// Setup create channel
var chanelName = 'mychannel';
const envelope = fs.readFileSync('/home/rosalva40/Documentos/Own2/Own/data/channel.tx');
channelConfig = fabric_client.extractChannelConfig(envelope);
signature = fabric_client.signChannelConfig(channelConfig);

const request = {
    name: chanelName,
    orderer: order,
    config: channelConfig,
    signatures : [signature],
    txId : fabric_client.newTransactionID(true)
};


//Create chanel
fabric_client.createChannel(request);

当我运行createChannel时。js，我在控制台中遇到以下错误：

2019-01-17T14:30:42.278Z-错误：[Remote.js]：错误：在截止日期URL之前连接失败：grpcs://localhost:91012019-01-17T14:30:42.283Z-错误：[order.js]：ordergrpcs://localhost:9101出现错误：在截止日期URL之前连接失败：grpcs://localhost:9101（节点：31051）未经处理的PromisejectionWarning:错误：在截止日期URL之前连接失败：grpcs://localhost:9101在checkState（/home/rosalva40/fabric samples/vote/node_modules/fabric client/node_modules/grpc/src/client.js:720:16）（node:31051）未经处理的Promisejection警告：未经处理的promise拒绝。这个错误要么是由于在没有catch块的情况下抛出异步函数的内部，要么是因为拒绝了没有使用catch块处理的promise。catch（）。（拒绝id:2）（节点：31051）[DEP0018]弃用警告：未处理的promise拒绝被弃用。将来，未处理的promise拒绝将终止节点。具有非零退出代码的js进程。

应用程序似乎在连接订购方时出现问题。尝试使用以下方法：

var Client = require('fabric-client');
var Channel = require('fabric-client').Channel;
const fs = require('fs');
var client = Client.loadFromConfig("config/configfile.yaml");
/**
 * @param {String} channelName Channel name used in configtxgen to create the channel transaction (mychannel)
 * @param {String} channelConfigPath Path of the channel transaction (/home/root/channel-artifacts/channel.tx)
 * @param {String} orderer Orderer name (orderer.example.com)
 * @description Create channel
 */
async createChannel(channelName,orderer, channelConfigPath) {
    var envelope = fs.readFileSync(channelConfigPath);
    var channelConfig = client.extractChannelConfig(envelope);
    let signature = client.signChannelConfig(channelConfig);
    let request = {
        config: channelConfig,
        orderer: client.getOrderer(orderer),
        signatures: [signature],
        name: channelName,
        txId: client.newTransactionID(true)
    };
    const result = await client.createChannel(request)
    return result;
}

您可以检查配置文件的结构。yaml在这个链接中。别忘了在配置文件中设置客户端头。亚马尔
