[英]Ninject Dependency Injection for SignalR
In my NinjectWebCommon.cs
file, under CreateKernel
method I am applying the injection like this 在我的
NinjectWebCommon.cs
文件中,在CreateKernel
方法下,我正在应用这样的注入
private static IKernel CreateKernel()
{
var kernel = new StandardKernel();
kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
RegisterServices(kernel);
// Web API Injection
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
// SignalR Injection
GlobalHost.DependencyResolver = new SignalR.Ninject.NinjectDependencyResolver(kernel);
return kernel;
}
I was thinking that should do it for me but i keep getting an error at the SignalR injection that 我在想,应该为我做这件事,但我在SignalR注射时不断收到错误
"Cannot implicitly convert type 'SignalR.Ninject.NinjectDependencyResolver' to 'Microsoft.AspNet.SignalR.IDependencyResolver'"
“无法将类型'SignalR.Ninject.NinjectDependencyResolver'隐式转换为'Microsoft.AspNet.SignalR.IDependencyResolver'”
Any idea what the problem is? 知道问题是什么吗?
I am not sure if you have found the answer or not. 我不确定你是否找到了答案。 They have changed the way DI works in SignalR as of version 1.0.0 and the SignalR.Ninject packages doesn't work - I have written a small blog post on this: http://myrandomcodesnippets.wordpress.com/2013/03/29/ninject-dependency-injection-with-signalr-1-0-1/
他们已经改变了DI在版本1.0.0中的工作方式,并且SignalR.Ninject软件包不起作用 - 我已经写了一篇关于此的小博客文章: http ://myrandomcodesnippets.wordpress.com/2013/03/ 29 / ninject依赖性喷射与-signalr-1-0-1 /
Basically you need to create your own implementation of this which is the same as the SignalR.Ninject implementation: 基本上你需要创建自己的实现,这与SignalR.Ninject实现相同:
GlobalHost.DependencyResolver = new SignalRNinjectDependencyResolver(kernel);
When you create the new class it will want to inherit from IDependancyResolver don't bother with this and use: 当你创建新类时,它希望从IDependancyResolver继承而不用这个并使用:
public class SignalRNinjectDependencyResolver : DefaultDependencyResolver
{
private readonly IKernel _kernel;
public SignalRNinjectDependencyResolver(IKernel kernel)
{
_kernel = kernel;
}
public override object GetService(Type serviceType)
{
return _kernel.TryGet(serviceType) ?? base.GetService(serviceType);
}
public override IEnumerable<object> GetServices(Type serviceType)
{
return _kernel.GetAll(serviceType).Concat(base.GetServices(serviceType));
}
}
Hope this helps. 希望这可以帮助。
