An ASP.NET Core Middleware Event-based for multiple WebSockets services with easy and low memory usage.
MariSocketMiddleware is very easy to use, just implement that in your ASP.NET core project.
using MariSocketMiddleware.Entities.MariEventArgs;
using MariSocketMiddleware.Services;
using Microsoft.AspNetCore.Http;
using System.Threading.Tasks;
namespace MyApi
{
public class MyWebSocketService : MariWebSocketService
{
public MyWebSocketService()
{
OnOpen += OpenAsync;
OnDisconnected += OnDisconnectedAsync;
OnError += OnErrorAsync;
OnMessage += OnMessageAsync;
}
private Task OnMessageAsync(MessageEventArgs arg)
=> Task.CompletedTask;
private Task OnErrorAsync(ErrorEventArgs arg)
=> Task.CompletedTask;
private Task OnDisconnectedAsync(DisconnectEventArgs arg)
=> Task.CompletedTask;
private Task OpenAsync(OpenEventArgs arg)
=> Task.CompletedTask;
public override string Path { get; set; } = "/Gateway";
public override Task<bool> AuthorizeAsync(HttpContext context)
=> Task.FromResult(true);
}
}using MariSocketMiddleware.Utils;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
namespace MyApi
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
// Here
// The generic type or the instance.
services.AddMariWebSocketService<MyWebSocketService>();
// ASP.NET Core template.
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
// ASP.NET Core template.
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
// Here
app.UseMariWebSockets();
// ASP.NET Core template.
app.UseHttpsRedirection();
app.UseMvc();
}
}
}Your service will be injected in the ASP.NET Core D.I, therefore you can get your service instance or get others services in your service.
using MariSocketMiddleware.Entities.MariEventArgs;
using MariSocketMiddleware.Services;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using System.Threading.Tasks;
namespace MyApi
{
public class MyWebSocketService : MariWebSocketService
{
private readonly ILogger<MyWebSocketService> _logger;
// ASP.NET Core will pass the dependencies in your class ctor.
public MyWebSocketService(ILogger<MyWebSocketService> logger)
{
_logger = logger;
OnOpen += OpenAsync;
OnDisconnected += OnDisconnectedAsync;
OnError += OnErrorAsync;
OnMessage += OnMessageAsync;
}
private Task OnMessageAsync(MessageEventArgs arg)
=> Task.CompletedTask;
private Task OnErrorAsync(ErrorEventArgs arg)
=> Task.CompletedTask;
private Task OnDisconnectedAsync(DisconnectEventArgs arg)
=> Task.CompletedTask;
private Task OpenAsync(OpenEventArgs arg)
=> Task.CompletedTask;
public override string Path { get; set; } = "/Gateway";
public override Task<bool> AuthorizeAsync(HttpContext context)
=> Task.FromResult(true);
}
}You can just pass your service in other service ctor or do a IServiceProvider#GetService.
using System;
using Microsoft.AspNetCore.Mvc;
namespace MyApi.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class ValuesController : ControllerBase
{
private readonly MyWebSocketService _service1;
private readonly MyOtherWebSocketService _service2;
public ValuesController(MyWebSocketService service1, IServiceProvider provider)
{
// Direct requesting your service or
_service1 = service1;
// Requesting for your provider.
_service2 = provider.GetService<MyOtherWebSocketService>();
}
// GET api/values
[HttpGet]
public ActionResult Get()
=> Ok(new string[] { "value1", "value2" });
