The context object in the ASP. SignalR Hub

Original: The context object in ASP. SignalR Hub

The context in the hub

When you use a hub, you'll find that comparing persistent connection classes with fewer events like onconnectioned, in fact there is. We need to go to override.

This seems to find out what the problem is, remember that there are connectionid and request parameters in the persistent connection class, and there is nothing here??? If there's a need to get connectionid.

In fact, there is no need to worry about it, because the context object has been encapsulated for us, as can be seen in the base class Hubbase, which is the Hubcallercontext type

F12 to see what's in this class, um ConnectionID, Headers, QueryString ... and so on.
