我如何在资源库中​​传递给在ASP.NET MVC的授权属性 [英] How do I pass in the repository to an authorize attribute in ASP.NET MVC

问题描述

我是温莎城堡，它在传递正在使用的存储库控制器构造的伟大工程。

I am castle Windsor and it works great for controller constructors in passing in the repository that is being used.

private IStoryRepository Repository;
public StoryController(IStoryRepository Repository)
{
    this.Repository = Repository;                   
}

现在我有一个动作是在管理方面显示主管理菜单。我已经使用了自定义授权属性，这将只是检查登录的用户是管理员（只是在用户表中的isAdmin标志）

Now I have an Action that is in the admin area to display the main admin menu. I have used a custom authorisation attribute which will just check that the logged in user is an admin (just an isAdmin flag in the users table)

 [AdminAuthorize]
 public ActionResult Menu()

 private IStoryRepository Repository;
 /// <summary>
 /// Initializes a new instance of the <see cref="AdminAuthorizeAttribute"/> class.
 /// </summary>
 public AdminAuthorizeAttribute(IStoryRepository Repository)
 {
     this.Repository = Repository;
 }

 /// <summary>
 /// Checks if the user is authorised
 /// </summary>
 /// <param name="httpContext">The HTTP context.</param>
 /// <returns>
 ///    <c>true</c> if authorized; otherwise, <c>false</c>.
 /// </returns>
 protected override bool AuthorizeCore(HttpContextBase httpContext)
 {
    return this.Repository.UserIsAdmin(httpContext.User.Identity.Name);
 }

我怎样才能城堡传递到存储库属性构造像它的控制器构造函数？

How can I get Castle to pass the repository into attribute constructor like it does for a controller constructor?

推荐答案

您基本上有两种选择。包裹过滤器代理的一个很好的例子可以发现的这里。

You basically have two options. Wrap the filter in a proxy, a good example of this can be found here.

或者，您的自定义过滤器中，你可以做一个明确的容器调用。例如使用StructureMap（我没有用过城堡广泛）

Or, within your custom filter you can do an explicit container call. For example using StructureMap (I have no used castle extensively)

ObjectFactory.GetInstance(IStoryRepository)

有可能是延长ActionInvoker做注射第三种方式，但我不知道如何做到这一点做的。

There may be a third way which is to extend the ActionInvoker to do the injection but I am not sure how this would be done.
