我正在编写一个严重依赖SignalR的应用程序.最近,我不得不选择卫星ISP提供商.这带来了一个大问题,看起来卫星的700毫秒延迟似乎给SignalR带来了困难.我可以测试延迟大约50ms的4G网络,那里的工作效果很好.我打开了客户端跟踪,问题是它何时尝试加入集线器.
以下是服务器上用于Join方法的代码:
public Task Join(string groupName)
{
var hub = GlobalHost.ConnectionManager.GetHubContext("myHub");
var results = hub.Groups.Add(Context.ConnectionId, groupName);
return results;
}
在日志中,我看到:
