无法从 Hyperledger Composer Playground 下载卡片

Question

我正在尝试从 Playground UI 导出我的网络管理卡，但导出图标被禁用。此外，我在 Chrome 控制台中看到以下错误：

错误：必须激活名称为 'admin' 且标识符为 'ddae16d6f23947e9349627051b8ca5933cef53d2918f52295352d7dd24cdabcb' 的当前身份。

如何从 Playground 导出网络管理员卡？

Answer 1

您可以通过composer-cli创建管理卡。

composer card create 
-p connection.json 
-u PeerAdmin -c Admin@org1.example.com-cert.pem 
-k 114aab0e76bf0c78308f89efc4b8c9423e31568da0c340ca187a9b17aa9a4457_sk 
-r PeerAdmin -r ChannelAdmin

添加 connection.json 文件如下：

{
  "name": "fabric-network",
  "type": "hlfv1",
  "mspID": "Org1MSP",
  "peers": [
      {
          "requestURL": "grpc://localhost:7051",
          "eventURL": "grpc://localhost:7053"
      }
  ],
  "ca": {
      "url": "http://localhost:7054",
      "name": "ca.org1.example.com"
  },
  "orderers": [
      {
          "url" : "grpc://localhost:7050"
      }
  ],
  "channel": "composerchannel",
  "timeout": 300
}

证书文件可以在 signcerts 子目录 (fabric-tools/fabric-scripts/hlfv1/composer/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp) 中找到并命名为 Admin@org1.example.com-cert.pem.

私钥文件可以在keystore子目录中找到。私钥文件的名字是一个很长的十六进制字符串，后缀为_sk，例如114aab0e76bf0c78308f89efc4b8c9423e31568da0c340ca187a9b17aa9a4457_sk。

Answer 2

这是我在GitHub上得到的答案：

The reason that the export is greyed out is because you are using the bluemix staged Playground that is in the 'web-connector' mode. In order to meaningfully export a business network card, you will need to create a connection to Hyperledger Fabric. The steps you outline above will not create a business network in Hyperledger Fabric, but within a web connector.

If you follow the developer tutorial (https://hyperledger.github.io/composer/tutorials/developer-tutorial) you will be taken through the process of creating a (local) Fabric, from which you can connect Playground and export business network cards.
