Hello Jo, to retrieve detailed log information from SignalR.SelfHost, you can enable server-side logging by using ConfigureLogging
. Here is a sample usage:
using Microsoft.AspNetCore.SignalR;
using Microsoft.Extensions.Logging;
public class MyHub : Hub
{
private readonly ILogger<MyHub> _logger;
public MyHub(ILogger<MyHub> logger)
{
_logger = logger;
}
public async Task SendMessage(string user, string message)
{
_logger.LogInformation($"Received message from {user}: {message}");
await Clients.All.SendAsync("ReceiveMessage", user, message);
}
}
You can then configure logging in your Startup.cs
file:
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddSignalR();
services.AddLogging();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddFile("Logs/myapp-{Date}.txt");
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapHub<MyHub>("/myhub");
});
}
}
This will log information to a file named myapp-{Date}.txt
in the Logs
folder. You can customize the logging behavior by modifying the loggerFactory
object. I hope this helps! Let me know if you have any further questions.
