asp.net-mvc - 如何为 MVC4 和自定义成员(member)提供配置 Ninject？

Question

根据本文描述custom-membership-provider-with-repository-injection

我实现了通过注入(inject)提供的自定义成员(member)资格。

自定义成员(member)供应商

using Ninject;

public class CustomMembershipProvider : MembershipProvider
{
        [Inject]
        public IUserRepository UserRepository { get; set; }

[...]

自定义角色提供者

using Ninject;

public class CustomRoleProvider : RoleProvider
{
      [Inject]
      public IUserRoleRepository UserRoleRepository { get; set; }
[...]

在 内网页配置

<membership defaultProvider="CustomsMembershipProvider">
      <providers>
        <clear/>
        <add name="CustomsMembershipProvider" type="namespace.CustomsMembershipProvider"/>
      </providers>
</membership>
<roleManager enabled="true" defaultProvider="customRoleProvider">
      <providers>
        <clear/>
        <add name="customRoleProvider" type="namespace.customRoleProvider"/>
      </providers>
</roleManager>

现在在 内NinjectWebCommon

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;
}

private static void RegisterServices(IKernel kernel)
{
  [...]

  kernel.Bind<IUserRepository>().To<UserRepository>();
  kernel.Bind<IUserRoleRepository>().To<UserRoleRepository>();

  // Inject user & role repository into our custom membership & role providers.
   kernel.Inject(Membership.Provider);
   kernel.Inject(Roles.Provider);
}

当我运行应用程序时出现错误

This method cannot be called during the application's pre-start initialization stage.

来自 kernel.Inject(Membership.Provider);这条线

但是如果我将内核设置放在 内申请_开始

我得到以下错误

Error activating IUserRepository No matching bindings are available, and the type is not self-bindable. Activation path: 2) Injection of dependency IUserRepository into property UserRepository of type CustomMembershipProvider 1) Request for CustomeMembershipProvider

如何解决。 ??

Answer 1

结果始终为空。为什么？因为asp.net 有它自己的成员静态属性。

这是membership.provider。并且此实例不是实例 ninject 管理的一部分。

要解决它，您需要使用 kernel.inject。但是在生成 aspnetmvc.cs 时，您会看到它是在 PreApplicationStart 事件上注入(inject)的，并且不会让您这样做。

这是 的独奏密码 为我解决问题。将此添加到您的 NinjectWebCommon

    [assembly: WebActivator.PreApplicationStartMethod(typeof(TopRankFantasy.App_Start.NinjectMVC3), "Start")]
    [assembly: WebActivator.PostApplicationStartMethod(typeof(TopRankFantasy.App_Start.NinjectMVC3), "RegisterMembership")]
    [assembly: WebActivator.ApplicationShutdownMethodAttribute(typeof(TopRankFantasy.App_Start.NinjectMVC3), "Stop")]

    public static void RegisterMembership()
    {
        bootstrapper.Kernel.Inject(Membership.Provider);
    }
