+我用过this solution使用 ASP.NET Web API 2、Owin 和 Identity 实现基于 token 的身份验证……效果非常好。我用这个other solution这是通过连接字符串传递承载 token 来实现 signalR 集线器授权和身份验证，但似乎承载 token 没有运行，或者某处有其他问题，这就是为什么我在这里寻求帮助......这些是我的代码... QueryStringBearerAuthorizeAttribute:这个是负责校验的类

        {
            var token = request.QueryString.Get("Bearer");
            var authenticationTicket = Startup.AuthServerOptions.AccessTokenFormat.Unprotect(token);

            if (authenticationTicket == null || authenticationTicket.Identity == null || !authenticationTicket.Identity.IsAuthenticated)
            {

            }

            request.Environment["server.User"] = new ClaimsPrincipal(authenticationTicket.Identity);
            request.Environment["server.Username"] = authenticationTicket.Identity.Name;
            request.GetHttpContext().User = new ClaimsPrincipal(authenticationTicket.Identity);
            return true;
        }

        public override bool AuthorizeHubMethodInvocation(IHubIncomingInvokerContext hubIncomingInvokerContext, bool appliesToMethod)
        {
            var connectionId = hubIncomingInvokerContext.Hub.Context.ConnectionId;

            // check the authenticated user principal from environment
            var environment = hubIncomingInvokerContext.Hub.Context.Request.Environment;
            var principal = environment["server.User"] as ClaimsPrincipal;

            if (principal != null && principal.Identity != null && principal.Identity.IsAuthenticated)
            {

                hubIncomingInvokerContext.Hub.Context = new HubCallerContext(new ServerRequest(environment), connectionId);

                return true;
            }

    var self = this;
    self.chatMessages = ko.observableArray();

    self.sendMessage = function () {
        if (!$('#message').val() == '' && !$('#name').val() == '') {
            $.connection.hub.qs = { Bearer: "yyCH391w-CkSVMv7ieH2quEihDUOpWymxI12Vh7gtnZJpWRRkajQGZhrU5DnEVkOy-hpLJ4MyhZnrB_EMhM0FjrLx5bjmikhl6EeyjpMlwkRDM2lfgKMF4e82UaUg1ZFc7JFAt4dFvHRshX9ay0ziCnuwGLvvYhiriew2v-F7d0bC18q5oqwZCmSogg2Osr63gAAX1oo9zOjx5pe2ClFHTlr7GlceM6CTR0jz2mYjSI" };
            $.connection.hub.start().done(function () {
                $.connection.hub.qs = { Bearer: "yyCH391w-CkSVMv7ieH2quEihDUOpWymxI12Vh7gtnZJpWRRkajQGZhrU5DnEVkOy-hpLJ4MyhZnrB_EMhM0FjrLx5bjmikhl6EeyjpMlwkRDM2lfgKMF4e82UaUg1ZFc7JFAt4dFvHRshX9ay0ziCnuwGLvvYhiriew2v-F7d0bC18q5oqwZCmSogg2Osr63gAAX1oo9zOjx5pe2ClFHTlr7GlceM6CTR0jz2mYjSI" };
                $.connection.impAuthHub.server.sendMessage($('#name').val(), $('#message').val())
                            .done(function () { $('#message').val(''); $('#name').val(''); })
                            .fail(function (e) { alert(e) });
            });
        }
    }

    $.connection.impAuthHub.client.newMessage = function (NAME, MESSAGE) {
        //alert(ko.toJSON(NAME, MESSAGE));
        var chat1 = new chat(NAME, MESSAGE);
        self.chatMessages.push(chat1);
    }

}

ko.applyBindings(new viewModel());

这是我的中心类...

using ImpAuth.Providers;
using Microsoft.AspNet.SignalR;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace ImpAuth
{
    public class impAuthHub : Hub
    {
        [QueryStringBearerAuthorize]
        public void SendMessage(string name, string message)
        {

            Clients.All.newMessage(name, message);
        }
    }
}

...现在当我尝试调用经过身份验证的集线器类时出现此错误

caller is not authenticated to invove method sendMessage in impAuthHub

但后来我在 QueryStringBearerAuthorizeAttribute 类中更改此方法以始终像这样返回 true

public override bool AuthorizeHubMethodInvocation(IHubIncomingInvokerContext hubIncomingInvokerContext, bool appliesToMethod)
{
    var connectionId = hubIncomingInvokerContext.Hub.Context.ConnectionId;
    // check the authenticated user principal from environment
    var environment = hubIncomingInvokerContext.Hub.Context.Request.Environment;
    var principal = environment["server.User"] as ClaimsPrincipal;

    if (principal != null && principal.Identity != null && principal.Identity.IsAuthenticated)
    {
        // create a new HubCallerContext instance with the principal generated from token
        // and replace the current context so that in hubs we can retrieve current user identity
        hubIncomingInvokerContext.Hub.Context = new HubCallerContext(new ServerRequest(environment), connectionId);

        return true;
    }

    return true;
}

...有效...我的代码或实现有什么问题？

最佳答案

你需要像这样配置你的信号器；

app.Map("/signalr", map =>
{
    map.UseCors(CorsOptions.AllowAll);

    map.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions()
    {
        Provider = new QueryStringOAuthBearerProvider()
    });

    var hubConfiguration = new HubConfiguration
    {
        Resolver = GlobalHost.DependencyResolver,
    };
    map.RunSignalR(hubConfiguration);
});

然后您需要为 signalR 编写一个基本的自定义 OAuthBearerAuthenticationProvider，它接受 access_token 作为查询字符串。

public class QueryStringOAuthBearerProvider : OAuthBearerAuthenticationProvider
{
    public override Task RequestToken(OAuthRequestTokenContext context)
    {
        var value = context.Request.Query.Get("access_token");

        if (!string.IsNullOrEmpty(value))
        {
            context.Token = value;
        }

        return Task.FromResult<object>(null);
    }
}

在此之后，您只需发送带有信号器连接的 access_token 作为查询字符串。

$.connection.hub.qs = { 'access_token': token };

对于您的集线器，只是普通的 [Authorize] 属性

public class impAuthHub : Hub
{
    [Authorize]
    public void SendMessage(string name, string message)
    {
       Clients.All.newMessage(name, message);
    }
}

希望这对您有所帮助。 YD.
