fabric-node-sdk 1.2 可以与 Fabric 1.1 网络一起使用吗？

Question

当我尝试在 Fabric 1.1 上创建通道时出现以下错误。是否有将 1.2 SDK 用于 Fabric 1.1 网络的解决方法？

Answer 1

只需从网络-config.yaml 文件中删除以下行。此文件用于加载连接配置。

 grpc-max-send-message-length: 15

Answer 2

sdk-node 从 1.1 到 1.2 的最关键部分是删除旧的 eventHub 库并迁移为使用 channelEventHub。

它看起来是一个重大变化，因为：

ChannelEventHub 绑定到通道和对等点，它使用端口 7051，而不是端口 7053 不再
连接机制有一些小的变化，建议在注册监听器之前显式调用channelEventHub.connect()。
