使用 ninject 绑定 ASP.NET Web API [英] ASP.NET Web API binding with ninject
问题描述
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.
I have just installed the mvc4 rc update and I am trying to build an api application with little luck.
我正在使用 ninject 但无法加载我的控制器.我一直收到错误
I am using ninject but cant get my controllers to load. I keep getting an error
Type 'Api.Controllers.ConsumerController' 没有默认构造函数
Type 'Api.Controllers.ConsumerController' does not have a default constructor
我对 mvc 和使用注入很陌生,所以请耐心等待.
I am very new to mvc and using injection so please bear with me.
我没有对通过 nuget 创建的默认绑定做任何特别的事情
I havent done anything special to the default binding that is created via nuget
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>();
}
}
我的控制器看起来像
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 控制器与 ninject 一起工作?
What do I need to do to get the api controllers to work with ninject?
对不起,如果这是简单的东西
Sorry if this is simple stuff
我尝试了你的建议 Michael 但是在将 webcommon.cs 更改为这个之后
I tried your suggestion Michael however after changing the the webcommon.cs to this
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>();
}
我在
var kernel = new StandardKernel();
被称为
程序集Ninject.Web.WebApi.Filter.DefaultFilterProvider"中的方法GetFilters"来自程序集Ninject.Web.WebApi,版本=3.0.0.0,Culture=neutral,PublicKeyToken=c7192dc5380945e7"没有实现.
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?
推荐答案
我问了 Brad Wilson关于这一点,它在 MVC4 RC 中发生了变化.
I asked Brad Wilson about this and it has changed in MVC4 RC.
GlobalConfiguration.Configuration.ServiceResolver 已移至 GlobalConfiguration.Configuration.DependencyResolver
使用此实现为您的 Web Api 创建 Ninject DependencyResolver:https://gist.github.com/2417226
Use this implementation to create a Ninject DependencyResolver for your Web Api: https://gist.github.com/2417226
在 NinjectWebCommon.cs 中:
// Register Dependencies
RegisterServices(kernel);
// Set Web API Resolver
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
