How to send Parameter/Query in HubConnection SignalR Core

Question

I'm trying to add parameter into connection to signalr.

I'm using Builder to create my Client connection and start it:

var connection = new HubConnectionBuilder()         .WithUrl("http://10.0.2.162:5002/connection")         .WithConsoleLogger()         .WithMessagePackProtocol()         .WithTransport(TransportType.WebSockets)         .Build();  await connection.StartAsync(); 

I want to send a simple parameter in this connection: Something Like:

"Token": "123"

In my server side i think i can take this parameter from HttpContext:

public override Task OnConnectedAsync() {     var httpContext = Context.Connection.GetHttpContext();     var token = httpContext.Request.Query["Token"];     return base.OnConnectedAsync(); } 

Any idea of how to send this parameter? Thanks.

I have found how to do this after much research:

On my build i just send the token from url connection. Like this:

var connection = new HubConnectionBuilder()         .WithUrl($"http://10.0.2.162:5002/connection?token={token}")         .WithConsoleLogger()         .WithMessagePackProtocol()         .WithTransport(TransportType.WebSockets)         .Build();
