go - 未实现的 desc = 未知服务 protos.ChaincodeSupport

Question

当我启动orderer、peer节点，然后我启动example01.go来实例化链码，并指定:

peer.address 192.168.120.189:7051 
chaincode.id.name simple-token:1.0.0

example01.go 的主要代码是:

func main() {
    viper.Set("chaincode.id.name","simple-token:1.0.0")
    err := shim.Start(new(SimpleChaincode))
    if err != nil {
        fmt.Printf("Error starting Simple chaincode: %s", err)
    }
}

在方法 shim.Start() 中错误发生在以下句子中:

err = chatWithPeer(chaincodename, stream, cc)//causes the error

但它显示错误:Unimplemented desc = unknown service protos.ChaincodeSupport进程已完成，退出代码为 0

您使用了错误的端口。在 v1.1 中端口是 7052 而不是像在 v1.0 中那样是 7051
