在授权2.0 SignalR [英] Authorization in SignalR 2.0

问题描述

我有一个窗体身份验证和承载SignalR集线器的另一台服务器的Web服务器。使用窗体身份验证cookie我想提取使用下面的code当前用户。这将使用HTTP模块是可能的，但使用SignalR时不能使用一个HTTP模块。

I have a Web server with forms authentication and another server that hosts the SignalR Hubs. Using the forms authentication cookie I want to extract the current user using the code below. This would be possible using a HttpModule, but when using SignalR a HttpModule cannot be used.

是否有任何其他方式来归档什么，我想做什么？

Is there any other way to archive what I want to do?

public class AuthorizationHubModule : HubPipelineModule
{
    public AuthorizationHubModule()
    {
    }

    protected override bool OnBeforeConnect(IHub hub)
    {
        var cookies = hub.Context.Request.Cookies;
        if (cookies.ContainsKey(".ASPXAUTH") == true)
        {
            // Get the user, populate the Thread.CurrentUser...
            Cookie cookie = cookies[".ASPXAUTH"];

            if (cookie != null)
            {
                FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(cookie.Value);

                GenericIdentity identity = new GenericIdentity(ticket.Name);
                GenericPrincipal principal = new GenericPrincipal(identity, new string[0]);

                // Cannot do this because User is readonly (this is possible in a normal HttpModule)
                //hub.Context.User = principal;
            }
        }

        return base.OnBeforeConnect(hub);
    }
}

我们之后，事情是设置与SignalR相关的IPrincipal。

The thing we are after, is to set the IPrincipal associated with SignalR.

推荐答案

原来，信号-R不能修改相关的IPrincipal因为SignalR没有设想做认证，但它可以从应用程序的认证范围内。所以这样做，因为@Shashank指出的正确方法，是用表格或任何你在你的应用程序中使用，并SignalR会从它那里得到这样的背景下。

Turns out that Signal-R cannot modify the associated IPrincipal because SignalR is not conceived to do authentication, but it gets the authentication context from the application. So the right way of doing this, as @Shashank has pointed out, is to use Forms or whatever you use in your application, and SignalR will get this context from it.
