使用HubConnection在SignalR中重新连接的正确逻辑

Posted 2021-04-12

我需要将客户端应用程序（SignalR）重新连接到服务器应用程序（SignalR），直到它连接。

但它始终有ConnectionState.Reconnecting ......所以我不知道如何重新连接。

我发现这种方法qazxsw poi说我们必须创建qazxsw poi作为一种独特的工作方法......

任何线索？

我的代码是

答案

所以我发现了这个最酷的解决方案HubConnection

System.Timers.Timer connectionChecker = new System.Timers.Timer(20000);
HubConnection Connection { get; set; }

private void  ConnectionChecker_ElapsedAsync(object sender, System.Timers.ElapsedEventArgs e)
{
    if (Connection.State == ConnectionState.Disconnected)
    {
        connectionChecker.Stop();
        ForceConnectAsync().Start(); // In this method await Connection.Start();
    }
    else if (Connection.State == ConnectionState.Connecting)
    {
        // After conection lost it keeps this state ALWAYS.
        // But once server is up it still has this state.
    }
    else if (Connection.State == ConnectionState.Reconnecting)
    {
    }
    else if (Connection.State == ConnectionState.Connected)
    {
    }
}
