使用webAPI承载令牌进行SignalR认证-Java 学习之路

我使用this solution来实现使用ASP.NET Web API 2，Owin和Identity的基于令牌的身份验证......这非常好用 . 我使用这个other solution来实现signalR集线器授权和身份验证，方法是通过连接字符串传递承载令牌，但看起来要么是承载令牌不行，要么某处出现其他错误，这就是为什么我在这里寻求帮助..这些是我的代码... QueryStringBearerAuthorizeAttribute：这是负责验证的类

using ImpAuth.Entities;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.OAuth;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Security.Claims;
using System.Threading.Tasks;
using System.Web;

namespace ImpAuth.Providers
{
    using System.Security.Claims;
    using Microsoft.AspNet.SignalR;
    using Microsoft.AspNet.SignalR.Hubs;
    using Microsoft.AspNet.SignalR.Owin;

    public class QueryStringBearerAuthorizeAttribute : AuthorizeAttribute
    {
        public override bool AuthorizeHubConnection(HubDescriptor hubDescriptor, IRequest request)
        {
            var token = request.QueryString.Get("Bearer");
            var authenticationTicket = Startup.AuthServerOptions.AccessTokenFormat.Unprotect(token);

            if (authenticationTicket == null || authenticationTicket.Identity == null || !authenticationTicket.Identity.IsAuthenticated)
            {
                return false;
            }

            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)
            {
                // 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 false;
        }
    }
}

这是客户端上的淘汰赛加jquery代码....

function chat(name, message) {
    self.Name = ko.observable(name);
    self.Message = ko.observable(message);
}

function viewModel() {
    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());

这是我的中心班......

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问题，我收到此错误

caller is not authenticated to invove method sendMessage in impAuthHub

但后来我在QueryStringBearerAuthorizeAttribute类中更改此方法，总是这样返回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;
}

......它有效....我的代码或实现有什么问题？

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，您只需要发送带有signalr连接的access_token作为查询字符串 .

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

而对于你的集线器只是普通的[授权]属性

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

希望这可以帮助 . YD .

无法发表评论，所以在对彼得的优秀答案发表评论后加上我的答案 .

在我的自定义owin授权提供程序中设置了更多的挖掘和用户ID隐藏在这里（显示完整的集线器方法） .

[Authorize]
    public async Task<int> Test()
    {
        var claims = (Context.User.Identity as System.Security.Claims.ClaimsIdentity).Claims.FirstOrDefault();
        if (claims != null)
        {
            var userId = claims.Value;

            //security party!
            return 1;
        }

        return 0;
    }

为texas697添加了更多：

Startup.Auth.cs将此添加到ConfigureAuth（）（如果尚未存在）：

app.Map("/signalr", map =>
    {
        map.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions()
        {
            Provider = new QueryStringOAuthBearerProvider() //important bit!
        });

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

自定义身份验证提供程序如下所示：

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);
    }
}
