c# – 使用Owin JWT身份的MVC

我试图找出如何从我的令牌中获得索赔.

我会尽量保持解释简短

>我有一个HTML页面,发布到我的web api的帖子,确实和auth
检查并返回JWT令牌
>当我收到令牌后,我想将它发送到不同的URL,我这样做的方式是使用查询字符串.我知道我可以使用cookies,但对于这个应用程序,我们不想使用它们.所以,如果我的网址看起来像这样http:// somedomain / checkout /?token = bearer token来到这里

我正在使用Owin中间件,这是我到目前为止所拥有的

app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
            {
                Provider = new ApplicationOAuthBearerAuthenticationProvider(),
            });

public class ApplicationOAuthBearerAuthenticationProvider
            : OAuthBearerAuthenticationProvider
        {

            public override Task RequestToken(OAuthRequestTokenContext context)
            {
                if (context == null)
                    throw new ArgumentNullException("context");

                var token = HttpContext.Current.Request.QueryString["token"];
                if (!string.IsNullOrEmpty(token))
                    context.Token = token;
                return Task.FromResult<object>(null);
            }
        }

但是我如何从令牌中获取声明或只是检查IsAuthenticated

我在我的控制器内部尝试了以下检查,但是IsAuthenticated总是假的

var identity = (ClaimsIdentity) HttpContext.Current.GetOwinContext().Authentication.User.Identity;
  if (!identity.IsAuthenticated)
      return;

  var id = identity.FindFirst(ClaimTypes.NameIdentifier);

最佳答案 好的,所以我设法搞清楚了.我上面的代码都运行良好,但我需要添加UseJwtBearerAuthentication中间件.

我最后改变原始代码的一件事是改变了context.Token = token; to context.Request.Headers.Add(“Authorization”,new [] {string.Format(“Bearer {0}”,token)});

所以我的启动课看起来像这样……

public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
            {
                Provider = new ApplicationOAuthBearerAuthenticationProvider(),
            });
            app.UseJwtBearerAuthentication(JwtOptions());

            ConfigureAuth(app);
        }


        private static JwtBearerAuthenticationOptions JwtOptions()
        {
            var key = Encoding.UTF8.GetBytes(ConfigurationManager.AppSettings["auth:key"]);
            var jwt = new JwtBearerAuthenticationOptions
            {
                AuthenticationMode = AuthenticationMode.Active,
                TokenValidationParameters = new TokenValidationParameters
                {
                    ValidAudience = Some Audience,
                    ValidIssuer = Some Issuer,
                    IssuerSigningToken = new BinarySecretSecurityToken(key),
                    RequireExpirationTime = false,
                    ValidateLifetime = false
                }
            };
            return jwt;
        }

        public class ApplicationOAuthBearerAuthenticationProvider
            : OAuthBearerAuthenticationProvider
        {

            public override Task RequestToken(OAuthRequestTokenContext context)
            {
                if (context == null)
                    throw new ArgumentNullException("context");

                var token = HttpContext.Current.Request.QueryString["token"];
                if (!string.IsNullOrEmpty(token))
                    context.Request.Headers.Add("Authorization", new[] { string.Format("Bearer {0}", token) });
                return Task.FromResult<object>(null);
            }
        }
    }
