+ iを使用 このソリューション は、ASP.NET Web API 2、Owin、およびIdentityを使用してトークンベースの認証を実装しました。私はこれを使用しました 他のソリューション そしてこれは、接続文字列を介してベアラートークンを渡すことによってsignalRハブの承認と認証を実装するために使用されましたが、ベアラートークンが機能していないか、どこか他のどこかが間違っているようです。なぜここでヘルプを探しているのですか...これらは私のコードです... QueryStringBearerAuthorizeAttribute:これは検証を担当するクラスです

これが私のハブクラスです...
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);
}
}
}
...認証されたハブクラスを呼び出そうとするとこの問題が発生し、このエラーが発生します
caller is not authenticated to invove method sendMessage in impAuthHub
しかし、私はQueryStringBearerAuthorizeAttributeクラスのこのメソッドを常にこのようにtrueを返すように変更します
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;
}
...それは機能します....何ISコードの問題OR実装?
このようにシグナルを設定する必要があります。
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);
});
次に、access_tokenをクエリ文字列として受け入れるsignalRの基本的なカスタムOAuthBearerAuthenticationProviderを記述する必要があります。
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);
}
}
この後、必要なのは、信号文字列接続としてaccess_tokenをクエリ文字列として送信することだけです。
$.connection.hub.qs = { 'access_token': token };
そしてあなたのハブのためにちょうど普通の[Authorize]属性
public class impAuthHub : Hub
{
[Authorize]
public void SendMessage(string name, string message)
{
Clients.All.newMessage(name, message);
}
}
お役に立てれば。 YD。
コメントできないので、ピーターのすばらしい答えに関するコメントの後に私の答えを追加します。
もう少し掘り下げて、カスタムowin認証プロバイダーで設定したユーザーIDがここに隠れていました(完全なハブメソッドを示しています)。
[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;
}
texas697 にさらに追加:
Startup.Auth.csがConfigureAuth()にまだ追加されていない場合は、これを追加します。
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);
});
カスタム認証プロバイダーは次のようになります。
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);
}
}
私は従った this :
最初にJWTをクエリ文字列に追加します。
this.connection = $['hubConnection']();
this.connection.qs = { 'access_token': token}
その後、startup.cs
、JwtBearerAuthenticationの前に、トークンをヘッダーに追加します。
app.Use(async (context, next) =>
{
if (string.IsNullOrWhiteSpace(context.Request.Headers["Authorization"]) && context.Request.QueryString.HasValue)
{
var token = context.Request.QueryString.Value.Split('&').SingleOrDefault(x => x.Contains("access_token"))?.Split('=')[1];
if (!string.IsNullOrWhiteSpace(token))
{
context.Request.Headers.Add("Authorization", new[] { $"Bearer {token}" });
}
}
await next.Invoke();
});
var keyResolver = new JwtSigningKeyResolver(new AuthenticationKeyContainer());
app.UseJwtBearerAuthentication(
new JwtBearerAuthenticationOptions
{
AuthenticationMode = AuthenticationMode.Active,
TokenValidationParameters = new TokenValidationParameters()
{
ValidAudience = ConfigurationUtil.ocdpAuthAudience,
ValidIssuer = ConfigurationUtil.ocdpAuthZero,
IssuerSigningKeyResolver = (token, securityToken, kid, validationParameters) => keyResolver.GetSigningKey(kid)
}
});
ValidateSignalRConnectionData(app);
var hubConfiguration = new HubConfiguration
{
EnableDetailedErrors = true
};
app.MapSignalR(hubConfiguration);
