Question

当我尝试在Fabric 1.1上创建频道时，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network-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节点从1.1更改为1.2的最关键部分是删除旧的eventHub库，并迁移为使用channelEventHub。

这看起来是一个重大变化，因为：

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

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