当我启动orderer,peer node,然后我启动example01.go来实例化链代码,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,错误发生在下面的句子中:
err = chatWithPeer(chaincodename, stream, cc)//causes the error
但它显示错误: 未实现的desc =未知服务protos.ChaincodeSupport进程完成退出代码0
