英文:
Golang: Broadcast messages to websocket when a particular POST JSON is received
问题
我有一个连接到我的goserver的应用程序，使用websocket进行连接。我使用了这段代码来创建websocket连接- https://github.com/gorilla/websocket/tree/master/examples/chat
http.HandleFunc("/ws", func(w http.ResponseWriter, r *http.Request) {
serveWs(hub, w, r)
})
当我收到一个POST请求时，我需要向所有设备广播一条消息- "Order Received: " + productNum。productNum是在POST请求中接收到的。
http.HandleFunc("/post", BroadcastMessage())
我想知道在BroadcastMessage()中需要编写什么来实现这个功能。请帮忙。

在BroadcastMessage中，将[]byte发送到中心的广播通道：
hub.broadcast <- message
英文:
In BroadcastMessage, send a []byte to the hub's broadcast channel:
hub.broadcast <- message
