是否可以将带有机器人的daml智能合约部署到Hyperledger Fabric？

Question

我基于示例“ fabl-on-fabric” https://github.com/hacera/daml-on-fabric部署了快速入门教程，此后，我尝试从dazl https://github.com/digital-asset/dazl-client/tree/master/samples/ping-pong部署pingpong示例。该示例中的机器人在daml ledger上运行良好。但是，当我尝试在光纤网络上部署此示例时，机器人无法发送交易。根据https://github.com/hacera/daml-on-fabric/blob/master/README.md的说明，一切正常。智能合约看起来像要部署在Fabric上。错误是当我尝试使用来自乒乓python文件https://github.com/digital-asset/dazl-client/blob/master/samples/ping-pong/README.md

的机器人时

I receive this error:

Answer 1

根据错误消息，似乎在快速入门示例中定义的参与方尚未分配到分类帐上，因此出现“分类帐上未知的参与者”错误。

您可以使用daml deploy --host = --port =来遵循https://docs.daml.com/deploy/index.html中的步骤，这将同时上传dars并在分类帐上分配各方。

[您也可以只运行分配方命令daml ledger dispatch-parties，它将基于您为daml.yaml定义的各方进行分配。
