Question

我有以下简单的ApiController示例失败。

public class TestAPIController : ApiController
{
    public TestAPIController(IKernel kernel) { }

    [HttpGet]
    public string Test()
    {
        return "success! " + DateTimeOffset.Now.ToString("F");
    }
}

这给了我错误：

加载Ninject组件ICache时出错没有在内核的组件容器中注册这样的组件。

我安装了Ninject.WebApi.DependencyResolver包但它仍然失败。

这是我在NinjectWebCommon中的CreateKernel类：

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

        kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

        //GlobalConfiguration.Configuration.DependencyResolver = new VBNinjectDependencyResolver(kernel);
        GlobalConfiguration.Configuration.DependencyResolver = new Ninject.WebApi.DependencyResolver.NinjectDependencyResolver(kernel);
        return kernel;
    }

使用：

Ninject 3.0.1.10

Ninject.MVC3 3.0.0.6

Ninject.Web.Common：3.0.0.7

Ninject.WebApi.DependencyResolver 0.1.4758.24814

提前感谢您的帮助。

干杯！

您不希望将IKernel注入控制器。相反，您希望注册您的服务，并将该服务注入控制器。

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;
}

private static void RegisterServices(IKernel kernel)
{
    kernel.Bind<IMyService>().To<MyService>().InRequestScope();
}      

// Your api controller
public class TestAPIController : ApiController
{
    private readonly IMyService _myService ;

    public TestAPIController(IMyService myService) 
    { 
        _myService = myService;
    }
}

在ApiController中Ninject绑定到IKernel失败，错误“加载Ninject组件ICache时出错”
