WebSocket(SuperSocket.WebSocket实现)服务端主动断开客户端的连接
使用SuperSocket.WebSocket实现的WebSocket服务端，当有WebSocket客户端连接上以后，WebSocket客户端如果发消息太长或者过大时，就会出现WebSocket主动断开客户端的连接的问题，解决如下：
using SuperSocket.SocketBase.Config;
using SuperWebSocket;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web;
namespace TESTeee
{
internal class Program
{
public static WebSocketServer ws = null;
static void Main(string[] args)
{
Console.WriteLine("WebSocket服务");
ws = new WebSocketServer();
ws.NewSessionConnected += Ws_NewSessionConnected;
ws.NewMessageReceived += Ws_NewMessageReceived;
ws.SessionClosed += Ws_SessionClosed;
//SuperSocket可以通过对ServerConfig对象进行设置，可以设置最大接收缓存大小(ReceiveBufferSize),也可以设置请求信息的最大长度(MaxRequestLength)有所限制，默认请求最大长度为1024. 该配置可以通过一个ServerConfig的对象进行设置
var config = new ServerConfig()
{
#region MyRegion
//public const int DefaultReceiveBufferSize = 4096;
//public const int DefaultListenBacklog = 100;
//public const int DefaultKeepAliveTime = 600;
//public const int DefaultSessionSnapshotInterval = 5;
//public const int DefaultSendBufferSize = 2048;
//public const int DefaultIdleSessionTimeOut = 300;
//public const int DefaultKeepAliveInterval = 60;
//public const int DefaultSendTimeout = 5000;
//public const int DefaultMaxRequestLength = 1024;
//public const int DefaultSendingQueueSize = 5;
//public const int DefaultMaxConnectionNumber = 100;
//public const int DefaultClearIdleSessionInterval = 120;
#endregion
// 限制请求的数据长度最大为1M
MaxRequestLength = 1024 * 1024,
ReceiveBufferSize = 1024 * 1024,
Ip = "127.0.0.1",
Port = 1234
};
//ws.Setup(config);
//if (!ws.Setup("127.0.0.1", 1234))
//if (!ws.Setup(config))
//{
// Console.WriteLine("ChatWebSocket 设置WebSocket服务侦听地址失败");
// return;
//}
ws.Setup(config, logFactory: new SuperSocket.SocketBase.Logging.ConsoleLogFactory());
if (!ws.Start())
{
Console.WriteLine("ChatWebSocket 启动WebSocket服务侦听失败");
return;
}
Console.WriteLine("ChatWebSocket 启动服务成功");
Console.ReadKey();
ws.Stop();
}
public static void Ws_NewSessionConnected(WebSocketSession session)
{
Console.WriteLine("{0:HH:MM:ss} 与客户端:{1}创建新会话", DateTime.Now, GetSessionName(session));
var msg = string.Format("{0:HH:MM:ss} {1} 进入聊天室", DateTime.Now, GetSessionName(session));
SendToAll(session, msg);
}
private static void Ws_NewMessageReceived(WebSocketSession session, string value)
{
var msg = string.Format("{0:HH:MM:ss} {1} 说: {2}", DateTime.Now, GetSessionName(session), value);
Console.WriteLine($"{msg}");
SendToAll(session, value);
}
public static void Ws_SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value)
{
Console.WriteLine("{0:HH:MM:ss} 与客户端:{1}的会话被关闭 原因：{2}", DateTime.Now, GetSessionName(session), value);
var msg = string.Format("{0:HH:MM:ss} {1} 离开聊天室", DateTime.Now, GetSessionName(session));
SendToAll(session, msg);
}
/// <summary>
/// 启动服务
/// </summary>
/// <returns></returns>
public static void Start()
{
if (!ws.Setup("127.0.0.1", 1234))
{
Console.WriteLine("ChatWebSocket 设置WebSocket服务侦听地址失败");
return;
}
if (!ws.Start())
{
Console.WriteLine("ChatWebSocket 启动WebSocket服务侦听失败");
return;
}
Console.WriteLine("ChatWebSocket 启动服务成功");
}
/// <summary>
/// 停止侦听服务
/// </summary>
public static void Stop()
{
if (ws != null)
{
ws.Stop();
}
}
public static string GetSessionName(WebSocketSession session)
{
return HttpUtility.UrlDecode(session.Path.TrimStart('/'));
}
public static void SendToAll(WebSocketSession session, string msg)
{
foreach (var sendSession in session.AppServer.GetAllSessions())
{
sendSession.Send(msg);
}
}
}
}
SuperSocket可以通过一个ServerConfig的对象进行配置设置，ServerConfig对象中默认配置如下：
//
// Summary:
// Default ReceiveBufferSize
public const int DefaultReceiveBufferSize = 4096;
//
// Summary:
// The default listen backlog
public const int DefaultListenBacklog = 100;
//
// Summary:
// The default keep alive time
public const int DefaultKeepAliveTime = 600;
//
// Summary:
// The default session snapshot interval
public const int DefaultSessionSnapshotInterval = 5;
//
// Summary:
// The default send buffer size
public const int DefaultSendBufferSize = 2048;
//
// Summary:
// Default idle session timeout
public const int DefaultIdleSessionTimeOut = 300;
//
// Summary:
// The default keep alive interval
public const int DefaultKeepAliveInterval = 60;
//
// Summary:
// Default send timeout value, in milliseconds
public const int DefaultSendTimeout = 5000;
//
// Summary:
// Default MaxRequestLength
public const int DefaultMaxRequestLength = 1024;
//
// Summary:
// Default sending queue size
public const int DefaultSendingQueueSize = 5;
//
// Summary:
// Default MaxConnectionNumber
public const int DefaultMaxConnectionNumber = 100;
//
// Summary:
// Default clear idle session interval
public const int DefaultClearIdleSessionInterval = 120;
