GO Websocket向所有客户发送消息

您必须使用连接池将消息广播到所有连接。您可以将其用作教程/示例http://gary.burd.info/go-websocket-
chat

简化：
连接池是已注册连接的集合。见

hub.connections

type connection struct {    // The websocket connection.    ws *websocket.Conn    // Buffered channel of outbound messages.    send chan []byte    // The hub.    h *hub}type hub struct {    // Registered connections. That's a connection pool    connections map[*connection]bool    ...}

为了广播所有客户端的消息，我们在连接池上进行如下迭代：

    case m := <-h.broadcast:        for c := range h.connections { select { case c.send <- m: default:     delete(h.connections, c)     close(c.send) }        }    }

h.broadcast

default

select
