因为想开发聊天的相关内容,所以学习一下t-io的知识
服务器端 pom.xml主要加入
服务器端首先实现消息处理
public class ShowcaseWsMsgHandler implements IWsMsgHandler {
private static Logger log = LoggerFactory.getLogger(ShowcaseWsMsgHandler.class);
public static final ShowcaseWsMsgHandler me = new ShowcaseWsMsgHandler();
private ShowcaseWsMsgHandler() {
}
/**
* 握手时走这个方法,业务可以在这里获取cookie,request参数等
*/
@Override
public HttpResponse handshake(HttpRequest request, HttpResponse httpResponse, ChannelContext channelContext) throws Exception {
String clientip = request.getClientIp();
String myname = request.getParam("name");
Tio.bindUser(channelContext, myname);
// channelContext.setUserid(myname);
log.info("收到来自{}的ws握手包\r\n{}", clientip, request.toString());
return httpResponse;
}
/**
* @param httpRequest
* @param httpResponse
* @param channelContext
* @throws Exception
* @author tanyaowu
*/
@Override
public void onAfterHandshaked(HttpRequest httpRequest, HttpResponse httpResponse, ChannelContext channelContext) throws Exception {
//绑定到群组,后面会有群发
Tio.bindGroup(channelContext, Const.GROUP_ID);
int count = Tio.getAll(channelContext.tioConfig).getObj().size();
String msg = "{name:'admin',message:'" + channelContext.userid + " 进来了,共【" + count + "】人在线" + "'}";
//用tio-websocket,服务器发送到客户端的Packet都是WsResponse
WsResponse wsResponse = WsResponse.fromText(msg, ShowcaseServerConfig.CHARSET);
//群发
Tio.sendToGroup(channelContext.tioConfig, Const.GROUP_ID, wsResponse);
}
/**
* 字节消息(binaryType = arraybuffer)过来后会走这个方法
*/
@Override
public Object onBytes(WsRequest wsRequest, byte[] bytes, ChannelContext channelContext) throws Exception {
return null;
}
/**
* 当客户端发close flag时,会走这个方法
*/
@Override
public Object onClose(WsRequest wsRequest, byte[] bytes, ChannelContext channelContext) throws Exception {
Tio.remove(channelContext, "receive close flag");
return null;
}
/*
* 字符消息(binaryType = blob)过来后会走这个方法
*/
@Override
public Object onText(WsRequest wsRequest, String text, ChannelContext channelContext) throws Exception {
WsSessionContext wsSessionContext = (WsSessionContext) channelContext.get();
HttpRequest httpRequest = wsSessionContext.getHandshakeRequest();//获取websocket握手包
if (log.isDebugEnabled()) {
log.debug("握手包:{}", httpRequest);
}
// log.info("收到ws消息:{}", text);
if (Objects.equals("心跳内容", text)) {
return null;
}
//channelContext.getToken()
//String msg = channelContext.getClientNode().toString() + " 说:" + text;
String msg = "{name:'" + channelContext.userid + "',message:'" + text + "'}";
//用tio-websocket,服务器发送到客户端的Packet都是WsResponse
WsResponse wsResponse = WsResponse.fromText(msg, ShowcaseServerConfig.CHARSET);
//群发
Tio.sendToGroup(channelContext.tioConfig, Const.GROUP_ID, wsResponse);
//返回值是要发送给客户端的内容,一般都是返回null
return null;
}
}
还有一个就是实现WsServerAioListener类
public class ShowcaseServerAioListener extends WsServerAioListener {
private static Logger log = LoggerFactory.getLogger(ShowcaseServerAioListener.class);
public static final ShowcaseServerAioListener me = new ShowcaseServerAioListener();
private ShowcaseServerAioListener() {
}
@Override
public void onAfterConnected(ChannelContext channelContext, boolean isConnected, boolean isReconnect) throws Exception {
super.onAfterConnected(channelContext, isConnected, isReconnect);
if (log.isInfoEnabled()) {
log.info("onAfterConnected\r\n{}", channelContext);
}
}
@Override
public void onAfterSent(ChannelContext channelContext, Packet packet, boolean isSentSuccess) throws Exception {
super.onAfterSent(channelContext, packet, isSentSuccess);
if (log.isInfoEnabled()) {
log.info("onAfterSent\r\n{}\r\n{}", packet.logstr(), channelContext);
}
}
@Override
public void onBeforeClose(ChannelContext channelContext, Throwable throwable, String remark, boolean isRemove) throws Exception {
super.onBeforeClose(channelContext, throwable, remark, isRemove);
if (log.isInfoEnabled()) {
log.info("onBeforeClose\r\n{}", channelContext);
}
WsSessionContext wsSessionContext = (WsSessionContext) channelContext.get();
if (wsSessionContext != null && wsSessionContext.isHandshaked()) {
int count = Tio.getAll(channelContext.tioConfig).getObj().size();
String msg = channelContext.getClientNode().toString() + " 离开了,现在共有【" + count + "】人在线";
//用tio-websocket,服务器发送到客户端的Packet都是WsResponse
WsResponse wsResponse = WsResponse.fromText(msg, ShowcaseServerConfig.CHARSET);
//群发
Tio.sendToGroup(channelContext.tioConfig, Const.GROUP_ID, wsResponse);
}
}
@Override
public void onAfterDecoded(ChannelContext channelContext, Packet packet, int packetSize) throws Exception {
super.onAfterDecoded(channelContext, packet, packetSize);
if (log.isInfoEnabled()) {
log.info("onAfterDecoded\r\n{}\r\n{}", packet.logstr(), channelContext);
}
}
@Override
public void onAfterReceivedBytes(ChannelContext channelContext, int receivedBytes) throws Exception {
super.onAfterReceivedBytes(channelContext, receivedBytes);
if (log.isInfoEnabled()) {
log.info("onAfterReceivedBytes\r\n{}", channelContext);
}
}
@Override
public void onAfterHandled(ChannelContext channelContext, Packet packet, long cost) throws Exception {
super.onAfterHandled(channelContext, packet, cost);
if (log.isInfoEnabled()) {
log.info("onAfterHandled\r\n{}\r\n{}", packet.logstr(), channelContext);
}
}
}
可以用官方的web客户端或websocketman进行测试,如下:
