I have a major issue I can not solve. I have a.net core 2 project with jwt auth and trying to get a basic signalr hub test to work. The connection from the client seems to work but the connection is promptly dropped with a 204 code.
My hub is running on another URL than my front end UI so CORS is involved.
**I removed real keys and my project name
this is what the client console outputs:
Here is my startup code:
public IServiceProvider ConfigureServices(IServiceCollection services)
{
services.Configure<ConnectionStrings>(Configuration.GetSection("ConnectionStrings"));
services.Configure<DiAssemblies>(Configuration.GetSection("DiAssemblies"));
services.Configure<StripeSettings>(Configuration.GetSection("Stripe"));
services.Configure<AzureStorageSettings>(Configuration.GetSection("AzureStorageSettings"));
// Add framework services.
services.AddApplicationInsightsTelemetry(Configuration);
services.AddCors(options =>
{
options.AddPolicy("CorsPolicy",
x => x.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials());
});
services.AddCors();
services.AddIdentity<testApp.Identity.ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<testApp.Identity.Context>()
.AddDefaultTokenProviders();
services.AddAuthentication(sharedOptions =>
{
sharedOptions.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
sharedOptions.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
sharedOptions.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(options =>
{
options.RequireHttpsMetadata = false;
options.SaveToken = true;
options.TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters()
{
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("authkeyasdfasdfasdfsadfasdfda")),
ValidIssuer = "https://testApp.com/",
ValidAudience = "https://testApp.com/",
};
options.Events = new JwtBearerEvents
{
OnAuthenticationFailed = context =>
{
Debug.WriteLine("Auth issue");
Debug.WriteLine(context.Exception);
return Task.CompletedTask;
},
OnMessageReceived = context =>
{
if (!context.Request.Headers.ContainsKey("Authorization") && !string.IsNullOrEmpty(context.Request.Query["authToken"]))
{
context.Request.Headers.Add("Authorization", context.Request.Query["authToken"]);
}
return Task.CompletedTask;
},
OnChallenge = context =>
{
Debug.WriteLine("Auth issue");
Debug.WriteLine(context.Error);
Debug.WriteLine(context.ErrorDescription);
return Task.CompletedTask;
}
};
});
services.AddMemoryCache();
services.AddMvc().AddJsonOptions(options =>
{
options.SerializerSettings.ContractResolver =
new CamelCasePropertyNamesContractResolver();
options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
});
services.AddSockets();
services.AddSignalRCore();
var builder = new ContainerBuilder();
// Register dependencies, populate the services from
// the collection, and build the container. If you want
// to dispose of the container at the end of the app,
// be sure to keep a reference to it as a property or field.
//builder.RegisterType<MyType>().As<IMyType>();
builder.Populate(services);
var diHelper = new DiHelper();
var diAssemblies = Configuration.GetValue<string>("DiAssemblies:List");
var assemblies = diHelper.GetAssemblies(diAssemblies.Split(',').ToList());
// Console.Write(diAssemblies);
builder.RegisterAssemblyModules(assemblies);
ApplicationContainer = builder.Build();
//foreach(var assembly in assemblies)
// services.AddMvc().AddApplicationPart(assembly).AddControllersAsServices();
// Create the IServiceProvider based on the container.
return new AutofacServiceProvider(ApplicationContainer);
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseCors(
options => options.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader()
);
app.UseAuthentication();
app.UseMvc();
app.UseSignalR(routes =>
{
routes.MapHub<ChatHub>("chat");
});
}
}
My Hub (a break point on any of the methods never gets hit)
public class ChatHub : Hub
{
public ChatHub()
{
var t = 0;
}
public override async Task OnConnectedAsync()
{
await Clients.Client(Context.ConnectionId).InvokeAsync("send", "connection made");
await base.OnConnectedAsync();
}
public Task Send(string message)
{
return Clients.All.InvokeAsync("send", message);
}
}
Client javascript:
<script>
window.connection;
window.connection = new signalR.HubConnection("https://localhost:44367/chat?authToken=" + 'bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.yyJzdWIiOiJhYzNkMTU3OC05YjU5LTRmNzQtOWMxYi01MWZlYjk2YmQ4YzEiLCJqdGkiOiJidnRlc3QxIiwiZXhwIjoxTYI2NjY1OTM3LCJpc3MiOiJodHRwczovL2Jpc3ZpbmUuY29tLyIsImF1ZCI6Imh0dHBzOi1vYmlzdmluZS5jb20vIn0.GxycqmyVsdHkW3M5yRH7arGkR3K-jAE2zrPrgoJnh-M',
{ transport: signalR.TransportType.LongPolling });
window.connection.on('send', function(message) {
alert(message);
});
window.connection.start().then(function() {
console.log("SignalR Connected: Chat");
window.connection.invoke('send',"hi").then(function (chats) {
console.log(chats);
});
}, function () {
});
</script>
