在 Hyperledger Composer 中生成 REST API 错误

Question

我正在按照教程生成带有 Digital Land Title Network 示例的 REST API。但我收到以下错误：

To restart the REST server using the same options, issue the following command:
   composer-rest-server -p defaultProfile -n digitalproperty-network -i WebAppAdmin -s DJY27pEnl16d -N always

Discovering types from business network definition ...

It will be retried for the next request.

在部署新的网络定义时也会发生这种情况……似乎无法与 Hyperledger Fabric 通信。但是 Fabric 正在运行

您正在运行 HLF 1.0.0-alpha 结构，但是当您启动其余服务器时，您指定了 defaultProfile，它是 hlf v0.6 的配置文件。当您部署 digitalproperty-network 时，您指定了一个配置文件 hlfv1（当您遵循快速入门指南时为您创建），这是您在启动其余服务器时需要使用的配置文件。
