HDC调试需求开发（15万预算）,能者速来！>>>
参照官方 WebSocket 的例子： public class WebSocketHandler implements IWsMsgHandler { @Override public HttpResponse handshake(HttpRequest request, HttpResponse httpResponse, ChannelContext channelContext) throws Exception { return httpResponse; } @Override public Object onBytes(WsRequestPacket websocketPacket, byte[] bytes, ChannelContext channelContext) throws Exception { return null; } @Override public Object onClose(WsRequestPacket websocketPacket, byte[] bytes, ChannelContext channelContext) throws Exception { return null; } @Override public Object onText(WsRequestPacket websocketPacket, String text, ChannelContext channelContext) throws Exception { return text; } } WebSocketHandler webSocketHandler = new WebSocketHandler(); WsServerStarter wsServerStarter = new WsServerStarter(); wsServerStarter.start(9321, webSocketHandler); ws = new WebSocket("ws://localhost:9321"); ws.onmessage = function (event) { alert(event.data); }; ws.onclose = function (event) { alert(event.data); }; ws.onopen = function (event) { ws.send("hello tio server"); }; ws.onerror = function (event) { alert(event.data); };
运行可以收到消息，现在我想在服务端主动推送消息给所有的客户端，查了下 API，有个
sendToAll 方法，但是参数 GroupContext 如何设置呢，我想给所有的客户端主动推送消息。 /** * 发消息到所有连接 * @param groupContext * @param packet * @param channelContextFilter * @author tanyaowu */ public static void sendToAll(GroupContext groupContext, Packet packet, ChannelContextFilter channelContextFilter) { sendToAll(groupContext, packet, channelContextFilter, false); }
