我正在测试 SignalR(通过 nuget 为 0.4.0),但找不到任何方法让服务器强制断开客户端。我想我错过了一些明显的东西。
我的测试代码如下,我在几乎所有我能想到的地方和组合中都尝试了 Close() 和 Timeout(),但没有成功。客户端继续接收脉冲消息,尽管我总是在前 4-5 秒内获得 2 次重新连接,这些连接似乎return Connection.Close()
来自OnReceivedAsync()
服务器:
internal class SignalRServer
{
private Server server;
public SignalRServer()
{
server = new Server("http://localhost:13170/");
server.MapConnection<EchoConnection>("/echo");
server.Start();
Timer timer = new Timer(1000);
timer.Elapsed += OnTimer;
timer.Enabled = true;
}
void OnTimer(object sender, ElapsedEventArgs e)
{
IConnectionManager manager = server.DependencyResolver.GetService(typeof(IConnectionManager)) as IConnectionManager;
IConnection connection = manager.GetConnection<EchoConnection>();
connection.Broadcast("pulse");
connection.Close();
connection.Timeout();
}
}
internal class EchoConnection : PersistentConnection
{
protected override Task OnConnectedAsync(IRequest request, IEnumerable<string> groups, string connectionId)
{
Connection.Timeout();
Connection.Close();
return Connection.Broadcast(String.Format("{0} connection", connectionId));
}
protected override Task OnReconnectedAsync(IRequest request, IEnumerable<string> groups, string connectionId)
{
return Connection.Broadcast(String.Format("{0} reconnection", connectionId));
}
protected override Task OnReceivedAsync(string connectionId, string data)
{
Console.WriteLine(data);
Connection.Close();
Connection.Timeout();
Connection.Broadcast(data);
return Connection.Close();
}
}
客户:
internal class SignalRClient
{
private readonly Connection connection;
public SignalRClient()
{
connection = new Connection("http://localhost:13170/echo");
connection.Received += OnReceive;
connection.Closed += OnClosed;
connection
.Start()
.ContinueWith(t =>
{
if (!t.IsFaulted)
connection.Send("Hello");
else
Console.WriteLine(t.Exception);
});
Console.WriteLine(connection.ConnectionId);
}
void OnClosed()
{
// never called
connection.Stop();
}
void OnReceive(string data)
{
Console.WriteLine(data);
}
}
示例客户端输出:
