We are trying to start our Signalr Hub with Dependency Injection using Autofac but with no result yet.
MVC and Web Apis are working fine with DI.
Here the config files.
Startup.cs
[assembly: OwinStartupAttribute(typeof(PNAME.WebUI.Startup))]
namespace PNAME.WebUI
{
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
var config = new HttpConfiguration();
// Register Routes
WebApiConfig.Register(config);
// Register dependencies
//ConfigureDependencies(app, config);
var container = DependencyConfiguration.Configure(app);
SignalRConfiguration.Configure(app, container);
MvcConfiguration.Configure(app, container);
WebApiConfiguration.Configure(app, container, config);
// Configure Authentication middleware
ConfigureAuth(app, config);
// configure Web API
app.UseWebApi(config);
}
}
}
DependencyConfiguration.cs
public static class DependencyConfiguration
{
public static IContainer Configure(IAppBuilder app)
{
var builder = new ContainerBuilder();
//Register any other components required by your code....
builder.RegisterType<MainContext>().As<IApplicationDbContext>();
builder.RegisterType<OneSignalNotificationService>().As<IPushNotificationService>();
builder.RegisterType<LogService>().As<ILogger>();
//Register SignalR Hub
builder.RegisterHubs(Assembly.GetExecutingAssembly());
//builder.RegisterType<ChatHub>().ExternallyOwned();
//Register MVC Controllers
builder.RegisterControllers(Assembly.GetExecutingAssembly());
//Register WebApi Controllers
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
builder.RegisterAssemblyModules(Assembly.GetExecutingAssembly());
var container = builder.Build();
app.UseAutofacMiddleware(container);
return container;
}
}
WebApiConfiguration.cs
public class WebApiConfiguration
{
public static void Configure(IAppBuilder app, IContainer container, HttpConfiguration config)
{
// Set the dependency resolver for Web API.
var webApiResolver = new AutofacWebApiDependencyResolver(container);
config.DependencyResolver = webApiResolver;
//Configure Action Injection
//config.InjectInterfacesIntoActions();
app.UseAutofacWebApi(config);
}
}
SignalRConfiguration.cs
public static class SignalRConfiguration
{
public static void Configure(IAppBuilder app, IContainer container)
{
//var config = new HubConfiguration();
//config.Resolver = new AutofacDependencyResolver(container);
//config.EnableDetailedErrors = true;
//app.MapSignalR("/signalr", config);
app.Map("/signalr", map =>
{
map.UseAutofacMiddleware(container);
var hubConfiguration = new HubConfiguration
{
Resolver = new AutofacDependencyResolver(container),
EnableDetailedErrors = true
};
map.RunSignalR(hubConfiguration);
});
}
}
MvcConfiguration.cs
public class MvcConfiguration
{
public static void Configure(IAppBuilder app, IContainer container)
{
var mvcResolver = new Autofac.Integration.Mvc.AutofacDependencyResolver(container);
DependencyResolver.SetResolver(mvcResolver);
app.UseAutofacMvc();
}
}
As for the ChatHub its located in another project as class library with different namespace as below
ChatHub.cs
namespace PNAME.BotServices.NotificationCenter.SignalR
{
[HubName("ChatHub")]
public class ChatHub : Hub
{
private ILogger _logger;
//private IChatMessageServices _chatMessageServices;
private readonly ILifetimeScope _hubLifetimeScope;
public ChatHub(ILifetimeScope lifetimeScope)
{
// Create a lifetime scope for the hub.
_hubLifetimeScope = lifetimeScope.BeginLifetimeScope("AutofacWebRequest");
// Resolve dependencies from the hub lifetime scope.
_logger = _hubLifetimeScope.Resolve<ILogger>();
// _chatMessageServices = _hubLifetimeScope.Resolve<IChatMessageServices>();
}
public bool SendMessage(INotificationMessage notificationMessage)
{
//Some code here
}
public override Task OnConnected()
{
//Some code here
}
public override Task OnReconnected()
{
//Some code here
}
public async Task UpdateStatus(int messageId, int ServerId, StatusType status)
{
//Some code here
}
protected override void Dispose(bool disposing)
{
// Dispose the hub lifetime scope when the hub is disposed.
if (disposing && _hubLifetimeScope != null)
{
_hubLifetimeScope.Dispose();
}
base.Dispose(disposing);
}
}
}
Thats all the configuration.
As I said in the MVC and API controllers are working well with DI only signalr not connecting from client and failing with the below error.
Microsoft.AspNet.SignalR.Client.HttpClientException: StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

don't know what did i miss in this configuration.
The issue was with the Hub name after changing the Hub name to "MyChatHub" every thing worked just fine with dependency injection

Having an issue getting a service instance in my controller. Followed the documentation from autofac's website but still getting an error. "None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'MyAssembly.Controllers.HeartBeatController' can be invoked with the available services and parameters:\r\nCannot resolve parameter 'MyAssembly.IO.IConfig config' of constructor 'Void .ctor(MyAssembly.IO.IConfig)'."
Here is my Global.asax file
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
var builder = new ContainerBuilder();
var config = GlobalConfiguration.Configuration;
WebApiConfig.Register(config);
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
var container = builder.Build();
BuildServices(builder);
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
config.EnsureInitialized();
log4net.Config.XmlConfigurator.Configure(new FileInfo(Server.MapPath("~/Web.config")));
}
private void BuildServices(ContainerBuilder builder)
{
builder.RegisterType<Config>().As<IConfig>().InstancePerRequest();
}
}
And here is my interface definition and class. Which is defined in the same assembly.
public interface IConfig
{
string GetSetting(string key);
T GetSetting<T>(string key);
}
public class Config : IConfig
{
public string GetSetting(string key)
{
return ConfigurationManager.AppSettings[key];
}
public T GetSetting<T>(string key)
{
var setting = GetSetting(key);
return setting != null ? (T)System.Convert.ChangeType(setting, typeof(T)) : default(T);
}
}
This is so ridiculous but I failed to build the services before the container. Oversight on my part and the below works.
BuildServices(builder);
var container = builder.Build();
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
config.EnsureInitialized();
My global.asax looks like below
private void BuildIocContainer()
{
var builder = new ContainerBuilder();
builder.RegisterModule(new BootstrapModule());
var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container); //Set the WebApi DependencyResolver
}
protected void Application_Start()
{
BuildIocContainer();
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
I have built a bootstrap module for autofac like the one below
public class BootstrapModule : Autofac.Module
{
private Assembly AssemblyOf<T>()
{
return typeof(T).Assembly;
}
private Assembly WebAssembly
{
get { return Assembly.GetExecutingAssembly(); }
}
private void RegisterMvc(ContainerBuilder builder)
{
builder.RegisterType<AsyncControllerActionInvoker>()
.As<IActionInvoker>();
builder.RegisterControllers(WebAssembly)
.InjectActionInvoker();
builder.RegisterApiControllers(WebAssembly).InjectActionInvoker();
}
private void RegisterLogger(ContainerBuilder builder)
{
builder.Register(CreateLogger)
.SingleInstance();
builder.Register(_ => new NLogWrapper(LogManager.GetLogger("DefaultLogger")))
.As<Logging.ILogger>()
.SingleInstance();
}
private static System.Func<Type, Logging.ILogger> CreateLogger(IComponentContext componentContext)
{
return type => new NLogWrapper(LogManager.GetLogger(type.FullName));
}
protected override void Load(ContainerBuilder builder)
{
RegisterLogger(builder);
RegisterMvc(builder);
builder.RegisterAssemblyTypes(WebAssembly)
.AsImplementedInterfaces();
builder.RegisterType<UserService>()
.As<IUserService>()
.InstancePerRequest();
builder.RegisterAssemblyTypes(typeof(IUserService).Assembly)
.AsImplementedInterfaces();
builder.RegisterAssemblyTypes(typeof(IUserRepository).Assembly)
.AsImplementedInterfaces();
builder.RegisterFilterProvider();
}
}
Now, when I try to hit account controller through postman client,
private IUserService _userService;
public AccountController(IUserService userService)
{
_userService = userService;
}
// POST api/Account/Register
[AllowAnonymous]
[Route("Register")]
public HttpStatusCode Register(User model)
{
if (!ModelState.IsValid)
{
return HttpStatusCode.BadRequest;
}
// TODO : Write mapper if needed
var user = new ToolUser()
{
FirstName = model.FirstName,
LastName = model.LastName,
EmailID = model.EmailID,
DOB = Convert.ToDateTime(model.DateOfBirth),
Gender = model.Gender.ToString(),
TenandID = model.TenantID,
Password = model.Password
};
HttpStatusCode result = _userService.RegisterUser(user);
return result;
}
I get the error
"An error occurred when trying to create a controller of type 'AccountController'. Make sure that the controller has a parameterless public constructor."
What am I doing wrong?
You should have something like
HttpConfiguration config = new HttpConfiguration();
somewhere, which you use to register your routes etc.
Pass that config to your BuildIocContainer() mehod and add the line
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
instead of
GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container); //Set the WebApi DependencyResolver
Hope that helps
I'm using this beriliant project for base of my MVC project.
But when I use WebAPI for project there is problem in IDataProtector injection.
I redesign base and upload here, and add a console project for testing authorizing with WebAPI.
This is structuremap initialization :
private static readonly Lazy<Container> _containerBuilder =
new Lazy<Container>(initStructureMap, LazyThreadSafetyMode.ExecutionAndPublication);
public static IContainer Container
{
get { return _containerBuilder.Value; }
}
return new Container(ioc =>
{
ioc.For<IUnitOfWork>().HybridHttpOrThreadLocalScoped().Use(() => new DbContext());
ioc.For<IDataSerializer<AuthenticationTicket>>().Use<TicketSerializer>();
ioc.For<ISecureDataFormat<AuthenticationTicket>>().Use<SecureDataFormat<AuthenticationTicket>>();
});
and in WebApiConfig class DI is like this:
var container = StructuremapMvc.Container;
GlobalConfiguration.Configuration.Services.Replace(
typeof(IHttpControllerActivator), new StructureMapHttpControllerActivator(container));
in my startup I create dataprotector with IAppBuilder :
public void ConfigureAuth(IAppBuilder app)
{
StructuremapMvc.Container.Configure(config =>
{
config.For<IDataProtectionProvider>()
.HybridHttpOrThreadLocalScoped()
.Use(() => app.GetDataProtectionProvider());
});
}
It start after WebApiConfig and IDataProtection not work in WebApi. my ServiceLayer is in separate project and DataProtection need to inject there.
you need add two class to your project :
1-StructureMapDependencyScope Class
using StructureMap;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http.Dependencies;
namespace Project.Helpers
{
public class StructureMapDependencyScope : IDependencyScope
{
protected readonly IContainer Container;
public StructureMapDependencyScope(IContainer container)
{
if (container == null)
{
throw new ArgumentNullException("container");
}
this.Container = container;
}
public void Dispose()
{
this.Container.Dispose();
}
public object GetService(Type serviceType)
{
if (serviceType == null)
{
return null;
}
try
{
return serviceType.IsAbstract || serviceType.IsInterface
? this.Container.TryGetInstance(serviceType)
: this.Container.GetInstance(serviceType);
}
catch
{
return null;
}
}
public IEnumerable<object> GetServices(Type serviceType)
{
return this.Container.GetAllInstances(serviceType).Cast<object>();
}
}
}
2-StructureMapDependencyResolver Class
using StructureMap;
using System.Web.Http.Dependencies;
namespace Project.Helpers
{
public class StructureMapDependencyResolver : StructureMapDependencyScope, IDependencyResolver
{
public StructureMapDependencyResolver(IContainer container)
: base(container)
{
}
public IDependencyScope BeginScope()
{
IContainer child = this.Container.GetNestedContainer();
return new StructureMapDependencyResolver(child);
}
}
}
at the end replace this code with yours in WebApiConfig Class:
// IoC Config
var container = SmObjectFactory.Container;
// Web API configuration and services
config.DependencyResolver = new StructureMapDependencyResolver(container);
read more about Dependency Injection in ASP.NET MVC 4 and Web API by StructureMap here.
You need to explicitly register implementation of IDataProtector in the container.
Sample configuration might looks like this:
ioc.For<IDataProtector>().Use(() => new DpapiDataProtectionProvider().Create("ASP.NET Identity"));
ioc.For<ITextEncoder>().Use<Base64UrlTextEncoder>();
Bear in mind that this specific configuration might not suit your exact needs.
Hope this helps!
I want to do integration tests on my Web API without depending on my business layer interfaces.
When this action is run:
1) I want to mock the _service object and just verify that is is called
2) I want to assert that the correct StatusCode is returned
Number 2 is no problem but how can I mock the _service object (ISchoolyearService) when I do not control/start the creation of the api controller manually because this is a task done in unit testing the controller. But I do not want to unit test my API !
[RoutePrefix("api/schoolyears")]
public class SchoolyearController : ApiController
{
private readonly ISchoolyearService _service;
public SchoolyearController(ISchoolyearService service)
{
_service = service;
}
[Route("")]
[HttpPost]
public HttpResponseMessage Post([FromBody]SchoolyearCreateRequest request)
{
_service.CreateSchoolyear(request);
return Request.CreateResponse(HttpStatusCode.Created);
}
Following is a crude example of how you can do with in-memory integration testing. Here I am using Unity.WebApi.UnityDependencyResolver to inject mock dependencies. You can use any other IoC container similarly.
using Microsoft.Practices.Unity;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System;
using System.Collections.Generic;
using System.IO;
using System.Net;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;
using System.Web.Http;
using Unity.WebApi;
namespace WebApplication251.Tests.Controllers
{
[TestClass]
public class PeopleControllerTest
{
string baseAddress = "http://dummyhost/";
[TestMethod]
public void PostTest()
{
HttpConfiguration config = new HttpConfiguration();
// use the configuration that the web application has defined
WebApiConfig.Register(config);
//override the dependencies with mock ones
RegisterMockDependencies(config);
HttpServer server = new HttpServer(config);
//create a client with a handler which makes sure to exercise the formatters
HttpClient client = new HttpClient(new InMemoryHttpContentSerializationHandler(server));
SchoolyearCreateRequest req = new SchoolyearCreateRequest();
using (HttpResponseMessage response = client.PostAsJsonAsync<SchoolyearCreateRequest>(baseAddress + "api/schoolyears", req).Result)
{
Assert.IsNotNull(response.Content);
Assert.IsNotNull(response.Content.Headers.ContentType);
Assert.AreEqual<string>("application/json; charset=utf-8", response.Content.Headers.ContentType.ToString());
SchoolyearCreateRequest recSCR = response.Content.ReadAsAsync<SchoolyearCreateRequest>().Result;
//todo: verify data
}
}
private void RegisterMockDependencies(HttpConfiguration config)
{
var unity = new UnityContainer();
unity.RegisterType<ISchoolyearService, MockSchoolyearService>();
config.DependencyResolver = new UnityDependencyResolver(unity);
}
}
[RoutePrefix("api/schoolyears")]
public class SchoolyearController : ApiController
{
private readonly ISchoolyearService _service;
public SchoolyearController(ISchoolyearService service)
{
_service = service;
}
[Route]
[HttpPost]
public HttpResponseMessage Post([FromBody]SchoolyearCreateRequest request)
{
_service.CreateSchoolyear(request);
return Request.CreateResponse(HttpStatusCode.Created);
}
}
public class InMemoryHttpContentSerializationHandler : DelegatingHandler
{
public InMemoryHttpContentSerializationHandler(HttpMessageHandler innerHandler)
: base(innerHandler)
{
}
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
request.Content = await ConvertToStreamContentAsync(request.Content);
HttpResponseMessage response = await base.SendAsync(request, cancellationToken);
response.Content = await ConvertToStreamContentAsync(response.Content);
return response;
}
private async Task<StreamContent> ConvertToStreamContentAsync(HttpContent originalContent)
{
if (originalContent == null)
{
return null;
}
StreamContent streamContent = originalContent as StreamContent;
if (streamContent != null)
{
return streamContent;
}
MemoryStream ms = new MemoryStream();
await originalContent.CopyToAsync(ms);
// Reset the stream position back to 0 as in the previous CopyToAsync() call,
// a formatter for example, could have made the position to be at the end
ms.Position = 0;
streamContent = new StreamContent(ms);
// copy headers from the original content
foreach (KeyValuePair<string, IEnumerable<string>> header in originalContent.Headers)
{
streamContent.Headers.TryAddWithoutValidation(header.Key, header.Value);
}
return streamContent;
}
}
}
I am using SignalR in my MVC3 application, and since I have implemented StructureMap Dependency Injection on my controllers I would like to do the same in my hub, but I can't seem to get it working.
Please tell me what's wrong with my codes below:
SignalRSmDependencyResolver.cs
public class SignalRSmDependencyResolver : DefaultDependencyResolver
{
private IContainer _container;
public SignalRSmDependencyResolver(IContainer container)
{
_container = container;
}
public override object GetService(Type serviceType)
{
object service = null;
if (!serviceType.IsAbstract && !serviceType.IsInterface && serviceType.IsClass)
{
// Concrete type resolution
service = _container.GetInstance(serviceType);
}
else
{
// Other type resolution with base fallback
service = _container.TryGetInstance(serviceType) ?? base.GetService(serviceType);
}
return service;
}
public override IEnumerable<object> GetServices(Type serviceType)
{
var objects = _container.GetAllInstances(serviceType).Cast<object>();
objects.Concat(base.GetServices(serviceType));
return objects;
}
}
SignalRExtensionsRegistry.cs
public class SignalRExtensionsRegistry : Registry
{
public SignalRExtensionsRegistry()
{
For<IDependencyResolver>().Add<SignalRSmDependencyResolver>();
}
}
IoC.cs
public static class IoC {
public static IContainer Initialize() {
var container = BootStrapper.Initialize();
container.Configure(x =>
{
x.For<IControllerActivator>().Singleton().Use<StructureMapControllerActivator>();
});
return container;
}
}
public class StructureMapControllerActivator : IControllerActivator {
public StructureMapControllerActivator(IContainer container) {
_container = container;
}
private IContainer _container;
public IController Create(RequestContext requestContext, Type controllerType) {
IController controller = DependencyResolver.Current.GetService(controllerType) as IController;
return controller;
}
}

DependencyResolver.SetResolver(new StructureMapDependenceyResolver(container));
AspNetHost.SetResolver(new StructureMapDependencyResolver(container));
}
}
}
NotificationsHub.cs

Getting Structuremap into SignalR is actually pretty easy. First you want to create your own resolver:
StructureMap Resolver
Usings:
using SignalR.Infrastructure;
using StructureMap;
Class:
public class StructureMapResolver : DefaultDependencyResolver
{
private IContainer _container;
public StructureMapResolver(IContainer container)
{
_container = container;
}
public override object GetService(Type serviceType)
{
object service = null;
if (!serviceType.IsAbstract && !serviceType.IsInterface && serviceType.IsClass)
{
// Concrete type resolution
service = _container.GetInstance(serviceType);
}
else
{
// Other type resolution with base fallback
service = _container.TryGetInstance(serviceType) ?? base.GetService(serviceType);
}
return service;
}
public override IEnumerable<object> GetServices(Type serviceType)
{
var objects = _container.GetAllInstances(serviceType).Cast<object>();
return objects.Concat(base.GetServices(serviceType));
}
}
The idea here is to try and use your container to resolve the dependencies, if you do not have the dependency wired up, pass it through to the default resolver. This way you don't have to worry about all of the other dependencies in SignalR and can focus only on the stuff you want to inject into (Hubs, ConnectionIdFactory, MessageBus, etc.).
Bindings for Resolver and Hub
Next you will want to register this in your container (i like using registries):
Usings:
using SignalR.Infrastructure;
using StructureMap.Configuration.DSL;
Class:
public class ExtensionsRegistry : Registry
{
public ExtensionsRegistry()
{
For<IDependencyResolver>().Add<StructureMapResolver>();
}
}
Resolver Replacement
Finally you will want to tell SignalR to use your resolver instead of the default:
Global::Application_Start or WebActivator::Pre_Start
Usings:
using SignalR.Hosting.AspNet;
using SignalR.Infrastructure;
Application_Start:
// Make sure you build up the container first
AspNetHost.SetResolver(StructureMap.ObjectFactory.GetInstance<IDependencyResolver>());
Silly Hub with injected dependencies
Now you can just inject any dependencies your container knows about into the hubs themselves:
[HubName("defaultHub")]
public class DefaultHub : Hub, IDisconnect
{
private readonly IRepository _repo;
public DefaultHub(IRepository repo)
{
_repo = repo;
}
public void Connect()
{
Caller.setUser(Context.ConnectionId);
Clients.addMessage(string.Format("{0} has connected", Context.ConnectionId));
}
public void MessageSender(string message)
{
Caller.addMessage(_repo.RepositoryMessage());
Clients.addMessage(message);
}
public Task Disconnect()
{
var clientId = this.Context.ConnectionId;
return Task.Factory.StartNew(() => { Clients.addMessage(string.Format("{0} has disconnected", clientId)); });
}
}
Have you followed the instructions here:- https://github.com/SignalR/SignalR/wiki/Extensibility ?
You'll need to use AspNetHost.SetResolver.
I know this is an old thread, but for those who are wondering where is the AspNetHost.SetResolver in the newer version of signalR, you can use this in the App_Start StructuremapMvc.cs:
public static void Start() {
IContainer container = IoC.Initialize();
GlobalHost.DependencyResolver = new SignalRSmDependencyResolver(container); // for signalR
DependencyResolver.SetResolver(new StructureMapDependencyResolver(container));
GlobalConfiguration.Configuration.DependencyResolver = new StructureMapDependencyResolver(container);
}
Add something like this to a file in your App_Start folder. This code snippet is for Ninject, so just replace AspNetHost.SetResolver()
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;
using Ninject;
using SignalR.Hosting.AspNet;
using SignalR.Infrastructure;
using SignalR.Ninject;
using Web.Models;
[assembly: WebActivator.PreApplicationStartMethod(typeof(Web.App_Start.NinjectSignalR), "Start")]
namespace Web.App_Start
{
public static class NinjectSignalR
{
public static void Start()
{
IKernel kernel = CreateKernel();
// switch this line to the structuremap resolver
AspNetHost.SetResolver(new NinjectDependencyResolver(kernel));
}
private static IKernel CreateKernel()
{
var kernel = new StandardKernel();
RegisterServices(kernel);
return kernel;
}
private static void RegisterServices(IKernel kernel)
{
// add your services here
//kernel.Bind<IRepository>().To<Repository>();
}
}
}
