本文介绍了Hyperledger Fabric 2.0.1:错误:在Discoverer名称上的截止日期之前无法连接:的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我认为Fabric一旦发现对等点和订购者确实存在但与机器IP地址不匹配，便会尝试发现它们.有没有一种方法可以为启用TLS的通信指定计算机IP覆盖?

I think Fabric is trying to discover peers and orderers as soon as they come to realize they do exist but not matching the machine IP address. Is there a way to specify the machine IP override for TLS enabled communication?

这是完整的日志

这就是我用来连接的东西:

This is what I'm using to connect:

'use strict';

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


async function main() {
    try {
        // load the network configuration
        const ccpPath = path.resolve(__dirname, '..', 'first-network', 'connection-org1.json');
        const ccp = JSON.parse(fs.readFileSync(ccpPath, 'utf8'));

        // Create a new file system based wallet for managing identities.
        const walletPath = path.join(process.cwd(), 'wallet');
        const wallet = await Wallets.newFileSystemWallet(walletPath);
        console.log(`Wallet path: ${walletPath}`);

        // Check to see if we've already enrolled the user.
        const identity = await wallet.get('appUser');
        if (!identity) {
            console.log('An identity for the user "appUser" does not exist in the wallet');
            console.log('Run the registerUser.js application before retrying');
            return;
        }

        // Create a new gateway for connecting to our peer node.
        const gateway = new Gateway();
        await gateway.connect(ccp, { wallet: wallet, identity: 'appUser', discovery: { enabled: true, asLocalhost: false } });

        // Get the network (channel) our contract is deployed to.
        const network = await gateway.getNetwork('evm');

        // Get the contract from the network.
        const contract = network.getContract('evmxxx');

        // Evaluate the specified transaction.
        const result = await contract.submitTransaction('getEVMAddress');
        console.log(`Transaction has been evaluated, result is: ${result.toString()}`);

    } catch (error) {
        console.error(`Failed to evaluate transaction: ${error}`);
        process.exit(1);
    }
}

main();

}

我无法使其连接，但是，它确实可以在同一台Fabric机器上使用localhost而不是在提供的示例IP地址作为grpcs url并将设置的发现选项asLocalHost设置为true的情况下工作.

I'm unable to make it connect, it does, however, work within the same Fabric machine using localhost instead of the provided example ip address as the grpcs url and setting the discovery options asLocalHost to true.

谢谢.

推荐答案

我在我的项目中也遇到了此错误.我在 connection_config.json 中错误地放置了 pem (我将文件的路径而不是实际的密钥LoL放置了.)

I encountered this error in my project as well. I put the pem incorrectly in my connection_config.json (I put the path to the file instead of the actual key, LoL..)

正确放置 pem 后，它可以正常工作.因此，请仔细检查 tlsCaCerts 的 pem 属性，并确保它们正确且格式正确.希望这会有所帮助.祝你好运！

After putting the pem correctly, it worked fine. So, maybe double-check the pem attributes of tlsCaCerts and make sure they are correct and in correct format. Hope this will help. Good luck!!!
