Hyperledger结构：未连接广播客户端xxx

问题描述

我使用以下两个sdk来连接扩展创建的局域网并与之交互。

package.json：

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

我首先要做的是在这里创建默认钱包：

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

我将其复制到工作区，然后使用以下功能将“ admin”身份添加到我的钱包中：

    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","signcerts"],pathIdentityKey: ["local-network","keystore"],}

我设法添加新的身份管理员：

{"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}

使用此身份，我可以getState提取我的资产：

但是，如果我尝试进行putState交易，则会出现此错误：

所有同行都来了：

我只是感到困惑，为什么不能使用putState交易。

我已经检查了我的智能合约是否良好，可以通过扩展名putState进行操作：

您的环境

IBM区块链平台扩展版本： 1.0.36
Visual Studio Code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

解决方法

我遇到了问题... 就在交易断开之前，我断开了网络连接...

  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。
