Hyperledger Fabric：广播客户端 xxx 未连接

Question

我使用以下两个 sdk 与扩展程序创建的本地网络进行连接和交互。

package.json:

   ...
    "fabric-ca-client": "^2.2.0",
    "fabric-network": "^2.2.0",
   ...

我首先做的是获取此处创建的默认钱包：

C:\Users\johnny.dacosta\.fabric-vscode\environments\chaincode-env

我将它复制到我的工作区，然后使用以下功能将“管理员”身份添加到我的钱包：

    if(this.walletProxy == null){
      //get wallet store
      this.walletProxy = await createWalletProxy(this.configService.get('localnetwork.orgWalletPath'));

      //build new identity
      const certBasePath = joinPathFromCWD(this.configService.get('localnetwork.pathIdentityCert'));
      const keyBasePath = joinPathFromCWD(this.configService.get('localnetwork.pathIdentityKey'));

      const certFilename = getFilesFromPath(certBasePath)[0];
      const keyFilename = getFilesFromPath(keyBasePath)[0];

      if(!certFilename || !keyFilename){
        throw new NotFoundException("certFilename or keyFilename not found");
      }

      const cert = readFileSyncUTF8(`${certBasePath}/${certFilename}`).toString();
      const key = readFileSyncUTF8(`${keyBasePath}/${keyFilename}`).toString();

      //add new identity
      await this.walletProxy.addIdentity(this.configService.get('localnetwork.identity'), {
        credentials: {
            certificate: cert,
            privateKey: key,
        },
        mspId: 'Org1MSP',
        type: 'X.509',
      })
    }

        //ENV
        {
      orgWalletPath: ["local-network", "wallets", "Org1", "admin", "user"],
      pathIdentityCert: ["local-network", "wallets", "Org1", "admin", "signcerts"],
      pathIdentityKey: ["local-network", "wallets", "Org1", "admin", "keystore"],
       }

我成功添加了新身份管理员：

{"credentials":{"certificate":"-----BEGIN CERTIFICATE-----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\nLK1NgJxMdYwxQYhGXSV568d+HJROXgb7+vsjd3g=\n-----END CERTIFICATE-----\n","privateKey":"-----BEGIN PRIVATE KEY-----\nMIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0wawIBAQQgGRpFEGhHS95y2Fyr\nLk6s6gd0V5D61akQC4RkEC1xYzmhRANCAAR+Q7RTGcp8QqYRKPQbHKNKHyWMVKBc\n4IWog1ejrqGcFvwzldAw0TgckWsnkBrRs9++U2MItem7gwZY3eYV/Wpv\n-----END PRIVATE KEY-----\n"},"mspId":"Org1MSP","type":"X.509","version":1}

有了这个身份，我可以 getState 我的资产：

但是如果我尝试进行 putState 交易，我会得到这个错误：

所有对等点都已启动：

我只是很困惑为什么不使用 putState 事务。

我已经检查过我的智能合约是好的，我可以设法用扩展进行 putState 操作：

您的环境

IBM 区块链平台扩展版本：1.0.36
Visual Studio代码版本：1.47.3
环境名称和版本：Node.js v10.16.3, npm v6.14.7):
操作系统和版本：Windows 10 Enterprise v1903

Answer 1

我遇到了问题... 就在交易之前我断开了网络...

  async submitTransaction(transactionConfig: ITransaction2HLF): Promise<void> {
    console.log(transactionConfig.transactionName)
    console.log(...transactionConfig.params)
    await this.buildInstance(transactionConfig);
    this.gateway.disconnect() // <-- ERROR
    await this.contract.submitTransaction(transactionConfig.transactionName, ...transactionConfig.params);
    this.gateway.disconnect()
  }

由于 vscode 扩展 ibm 区块链平台要求，我刚刚删除了该行并将版本 2.2 降级为 1.4.x。
