很早之前爲了快速達到效果,使用輪詢實現了在線聊天功能,後來無心接觸了socket,關於socket個人理解是進程間通訊,首先要有服務器跟客戶端,服務的啓動監聽某ip端口定位該進程,客戶端開啓socket分配ip端口鏈接服務端ip端口,因而兩個進程間即可以通訊了。下面簡單畫個圖理解。javascript
but,今天仍是準備分享websocket的使用,先上效果,再貼代碼。java
第一步啓動socket服務。jquery
而後鏈接客戶端鏈接服務器,加入聊天室,分別使用googel(白玉京,沈浪),火狐(楚留香),ie(李尋歡)進行測試,效果以下。web
*瀏覽器
*****************斷開一下。服務器
******************斷開一下。websocket
下面是本次測試源碼。session
服務端:app
public class TestWebSocketController : Controller { WebSocketServer server; List<SessionInfo> listSession = new List<SessionInfo>(); public ActionResult Index() { return View(); } //服務啓動 public string Start() { var ip = "192.168.1.106"; var port = "1010"; server = new WebSocketServer(); if (!server.Setup(ip, int.Parse(port))) { return "WebSocket服務啓動Error"; } //新的會話鏈接 server.NewSessionConnected += SessionConnected; //會話關閉 server.SessionClosed += SessionClosed; //新的消息接收 server.NewMessageReceived += MessageReceived; if (!server.Start()) { //處理監聽失敗消息 return "error"; } return "success"; } /// <summary> /// 會話關閉 /// </summary> /// <param name="session"></param> /// <param name="value"></param> private void SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value) { Debug.WriteLine("會話關閉,關閉緣由:{0} 來自:{1} 時間:{2:HH:MM:ss}", value, session.RemoteEndPoint, DateTime.Now); //SendMsgToRemotePoint(SessionId, SessionId + "已斷開"); var sessionRemove = listSession.FirstOrDefault(s => s.SessionId == session.SessionID); listSession.Remove(sessionRemove); } /// <summary> /// 會話鏈接 /// </summary> /// <param name="session"></param> private void SessionConnected(WebSocketSession session) { Debug.WriteLine("新的會話鏈接 來自:{0} SessionID:{1} 時間:{2:HH:MM:ss}", session.RemoteEndPoint, session.SessionID, DateTime.Now); listSession.Add(new SessionInfo { SessionId = session.SessionID, EndPoint = session.RemoteEndPoint.ToString() }); } /// <summary> /// 消息接收 /// </summary> /// <param name="session"></param> /// <param name="value"></param> private void MessageReceived(WebSocketSession session, string value) { //反序列化消息內容 var message = JsonConvert.DeserializeObject<MessageInfo>(value); foreach (var item in listSession) { ///發送消息 SendMsg(item.SessionId, string.Format("{0}發來消息:{1}", message.Name, message.Message)); } } // <summary> /// 發送消息 /// </summary> /// <param name="sessionId"></param> /// <param name="msg"></param> private void SendMsg(string sessionId, string msg) { var appSession = server.GetAppSessionByID(sessionId); if (appSession != null) appSession.Send(msg); } public class MessageInfo { public string Name { get; set; } public string Message { get; set; } } public class SessionInfo { public string SessionId { get; set; } public string EndPoint { get; set; } //public string Name { get; set; } } }
