How do I call a SignalR hub method from the outside?

Question

This is my Hub code:

public class Pusher : Hub, IPusher
{
    readonly IHubContext _hubContext = GlobalHo         


        

Answer 1

Take a look at this link at the topic of (How to call client methods and manage groups from outside the Hub class).
Code example simply creates a singleton instance of the caller class and pass in the IHubContext into it's constructor. Then you have access to desired context.Clients in caller class's methods:

// This sample only shows code related to getting and using the SignalR context.
public class StockTicker
{
    // Singleton instance
    private readonly static Lazy _instance = new     Lazy(() => new StockTicker(GlobalHost.ConnectionManager.GetHubContext()));

private IHubContext _context;

private StockTicker(IHubContext context)
{
    _context = context;
}

// This method is invoked by a Timer object.
private void UpdateStockPrices(object state)
{
    foreach (var stock in _stocks.Values)
    {
        if (TryUpdateStockPrice(stock))
        {
            _context.Clients.All.updateStockPrice(stock);
        }
    }
}
