c# - ASP.NET Web API 与 ninject 绑定(bind)

Question

我刚刚安装了 mvc4 rc 更新，我正在尝试构建一个 api 应用程序，但运气不佳。

我正在使用 ninject 但无法加载我的 Controller 。我不断收到错误

Type 'Api.Controllers.ConsumerController' does not have a default constructor

我对 mvc 和使用注入(inject)非常陌生，所以请多多包涵。

我没有对通过 nuget 创建的默认绑定(bind)做任何特殊的事情

 public static class NinjectWebCommon 
{
    private static readonly Bootstrapper bootstrapper = new Bootstrapper();

    /// <summary>
    /// Starts the application
    /// </summary>
    public static void Start() 
    {
        DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
        DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
        bootstrapper.Initialize(CreateKernel);
    }

    /// <summary>
    /// Stops the application.
    /// </summary>
    public static void Stop()
    {
        bootstrapper.ShutDown();
    }

    /// <summary>
    /// Creates the kernel that will manage your application.
    /// </summary>
    /// <returns>The created kernel.</returns>
    private static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
        kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

        RegisterServices(kernel);
        return kernel;
    }

    /// <summary>
    /// Load your modules or register your services here!
    /// </summary>
    /// <param name="kernel">The kernel.</param>
    private static void RegisterServices(IKernel kernel)
    {
        kernel.Bind<IConsumerRepository>().To<ConsumerRepository>();
    }        
}

我的 Controller 看起来像

   private readonly IConsumerRepository _repository;

    public ConsumerController(IConsumerRepository repository)
    {
        _repository = repository;
    }

    [HttpGet]
    public IQueryable<Consumer> Get(Guid id)
    {
        return _repository.Get(id).AsQueryable();
    }

我需要做什么才能让 api Controller 与 ninject 一起工作？

对不起，如果这是简单的事情

我尝试了迈克尔的建议，但是在将 webcommon.cs 更改为这个之后

  private static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
        kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

        RegisterServices(kernel);
        GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
        return kernel;
    }

    /// <summary>
    /// Load your modules or register your services here!
    /// </summary>
    /// <param name="kernel">The kernel.</param>
    private static void RegisterServices(IKernel kernel)
    {
        kernel.Bind<IConsumerRepository>().To<ConsumerRepository>();
    }

当

我得到一个错误

var kernel = new StandardKernel();

被称为

Method 'GetFilters' in type 'Ninject.Web.WebApi.Filter.DefaultFilterProvider' from assembly 'Ninject.Web.WebApi, Version=3.0.0.0, Culture=neutral, PublicKeyToken=c7192dc5380945e7' does not have an implementation.

我错过了什么？

Answer 1

我问了Brad Wilson关于这一点，它在 MVC4 RC 中发生了变化。

GlobalConfiguration.Configuration.ServiceResolver 已移至 GlobalConfiguration.Configuration.DependencyResolver

使用此实现为您的 Web Api 创建一个 Ninject DependencyResolver: https://gist.github.com/2417226

在NinjectWebCommon.cs中:

// Register Dependencies
RegisterServices(kernel);

// Set Web API Resolver
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
