与现有的授权集成SignalR [英] Integrating SignalR with existing Authorization

问题描述

我一直在努力将SignalR授权的方式使用自定义的授权供应商（称为MVCAuthorization）属性我下楼的试图重新为中心专门授权提供了几个洞的兔子，但竟然是远太过复杂。所以我在想，我怎么能我现有的控制器和动作授权整合与我SignalR集线器和方法是什么？

I've been working on a way of integrating SignalR Authorization Attributes with a custom authorization provider (called MVCAuthorization) I went down a few rabbit holes of trying to recreate an Authorization provider for hubs specifically, but that turned out to be far too complicated. So I was wondering, how I can integrate my existing Controller and Action Authorization with my SignalR Hubs and methods?

推荐答案

我想通了，你可以检索IAuthorization提供商。

I figured out that you can retrieve an IAuthorization provider.

如果你把你的集线器控制器，你的方法为你的行动，你所要做的就是创建一个实现一个SignalR属性IAuthorizeHubConnection和IAuthorizeHubMethodInvocation

If you treat you hub as a controller, and your methods as your actions, all you have to do is create a SignalR Attribute that implements IAuthorizeHubConnection and IAuthorizeHubMethodInvocation

public class HubAuthorizeAttribute : Attribute, IAuthorizeHubConnection,IAuthorizeHubMethodInvocation
{
    public virtual bool AuthorizeHubConnection(HubDescriptor hubDescriptor, Microsoft.AspNet.SignalR.IRequest request)
    {
        IAuthorizationProvider authorizationProvider = DependencyResolver.Current.GetService<IAuthorizationProvider>();

        return authorizationProvider.IsAuthorizedController(hubDescriptor.Name);
    }

    public virtual bool AuthorizeHubMethodInvocation(IHubIncomingInvokerContext hubIncomingInvokerContext)
    {
        IAuthorizationProvider authorizationProvider = DependencyResolver.Current.GetService<IAuthorizationProvider>();

        return authorizationProvider.IsAuthorizedAction(hubIncomingInvokerContext.MethodDescriptor.Hub.Name, hubIncomingInvokerContext.MethodDescriptor.Name);
    }
}

然后，所有你所要做的就是把属性上的集线器或你想要授权的任何方法

Then all you have to do is put the attribute on your hub or any methods you want authorized

[HubAuthorize]
public class Message : Hub
{
    public void Send(string message)
    {
    }
}
