无法通过 NodeJS query/invoke Hyperledger Fabric Peers（在 docker 群网络中）- GRPC/S 截止日期错误

Question

进程我已经通过 CLI 安装、查询、调用 fabcar 链代码。一切顺利。

enrolAdmin.js 和 registerUser.js 成功。

BUT 当我运行 query.js 我有以下错误

错误

error: [Remote.js]: Error: Failed to connect before the deadline URL:grpc://192.168.56.171:7051
error: [Remote.js]: Error: Failed to connect before the deadline URL:grpc://192.168.56.171:8051

Failed to evaluate transaction: Error: Unable to initialize channel. Attempted to contact 2 Peers. Last error was Error: Failed to connect before the deadline URL:grpc://192.168.56.171:8051

仅供参考 - 我已经在禁用和启用 TLS 的情况下进行了相同的测试。仍然失败

环境在 docker swarm 的帮助下，我扩展了 Hyperledger Fabric first-network e2e 以在多个主机上工作。

连接配置文件（无 TLS）如下

            "caName": "ca.org2.example.com"
        }
    }
}

docker的片段-组成文件结构如下，

networks:
  hyperledger:
        external: 
            name: hyperledger
  peer0.org1.example.com:
    container_name: peer0.org1.example.com
    -----------------------
    -----------------------
    -----------------------
    ports:
      - 7051:7051
    networks:
      hyperledger:
        aliases:
         - peer0.org1.example.com

预期结果 - 通过 NodeJS

连接到 Hyperledger docker 群容器

Answer 1

我已经找到问题的解决方案。确保 telnet 从网络外部连接到所需的容器。通过运行

telnet 192.168.128.171 7051

如果 Telnet 不起作用 --> 问题一定是因为端口 published/exposed 不正确。首先检查以下内容，

确保 CORE_PEER_LISTENADDRESS 设置为监听 docker-compose 文件中的所需端口。如下，对于 peer0.org1.eaxmple.com --> 7051,

CORE_PEER_LISTENADDRESS=0.0.0.0:7051

如果 Telnet 有效 --> 检查连接配置文件。如果启用了 TLS，请确保正确传递了 tls certificates/PEM 文件并将连接设置为 GRPCS（不是 GRPC）

连接配置文件

            "certificateAuthorities": [

                "ca.org1.example.com"

            ],

            "adminPrivateKey": {

                "path": "crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/keystore/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX_sk"

            },

            "signedCert": {

                "path": "crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/signcerts/Admin@org1.example.com-cert.pem"

            }

        "peer0.org1.example.com": {

            "url": "grpcs://192.168.128.171:7051",

            "grpcOptions": {

                "ssl-target-name-override": "peer0.org1.example.com",

                "request-timeout": 120001

            },

            "tlsCACerts": {

                "path": "crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp/tlscacerts/tlsca.org1.example.com-cert.pem"

            }

        },

Answer 2

我推荐使用域。修改 /etc/hosts

192.168.100.100 peer0.org1.example.com
192.168.100.100 peer1.org1.example.com
192.168.100.100 orderer.example.com
192.168.100.100 orderer.example.com
192.168.100.100 orderer3.example.com
192.168.100.100 orderer4.example.com
192.168.100.100 orderer5.example.com

修改连接-org1.json

"peers": {
    "peer0.org1.example.com": {
        "url": "grpcs://peer0.org1.example.com:7051",


"peers": {
    "peer0.org1.example.com": {
        "url": "grpcs://peer0.org1.example.com:7051",

修改代码

await gateway.connect(ccpPath, { wallet, identity: 'user1', discovery: { enabled: true, asLocalhost: false } });
