First of all, the main purpose of using websockets is to let the backend actively push data to the frontend to process the display

1: SignalR connects to the server for the first time



When we open the page, we want the websocket connection to be successful, and then push the existing data to us first, what should we do?

First, we inherit the Hub class and then rewrite the OnConnected method with the code as follows:


//
        Summary:
        //     Called when the connection connects to this hub instance.
        //
        Return results:
        //     A System.Threading.Tasks.Task
        public virtual Task OnConnected();
After the signalr user connects successfully for the first time, the OnConnected method is triggered, and the Context.ConnectionId is the generated customer ID



Call the Clients.Client method to push data to the specified client Id, and the following all method is defined by ourselves.



2: Actively push data to the front desk

How to actively push data to the front desk through SignalR?

js method is as follows:
