如何从Phoenix Controller向频道广播消息? [英] How to broadcast a message from a Phoenix Controller to a Channel?

问题描述

是否可以从该频道外部向该频道广播消息?

Is there a way to broadcast a message to a channel from outside that channel?

也许像Channel.broadcast topic, event, data一样?

我在此处看到了类似的内容，但是Phoenix.Channel.broadcast/3的最终版本(截至今天)表示频道和主题的套接字.

I saw something like this here but the final version of Phoenix.Channel.broadcast/3 (as of today) takes a socket which implies the channel and topic.

推荐答案

您可以使用MyApp.Endpoint.broadcast(topic, event, msg).
