Question

我的elmah日志显示此错误。每次请求都不会发生这种情况。它间歇性地发生。 MVC 5.2，Web API 2.2，ASP.NET Identity 2和Azure网站是我的环境。更新：这是我的Startup.cs，

        OAuthOptions = new OAuthAuthorizationServerOptions()
        {
            AllowInsecureHttp = true,
            TokenEndpointPath = new PathString("/token"),
            AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(settings.AccessTokenExpireTimeSpanInMinutes),
            Provider = new MyAuthorizationServerProvider(),
            RefreshTokenProvider = new MyRefreshTokenProvider()
        };
        // Web API configuration and services
        // Configure Web API to use only bearer token authentication.
        GlobalConfiguration.Configuration.SuppressDefaultHostAuthentication();
        GlobalConfiguration.Configuration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType));
        app.UseOAuthAuthorizationServer(OAuthOptions);
        app.UseOAuthBearerAuthentication(OAuthBearerOptions);

        GlobalConfiguration.Configuration.SuppressDefaultHostAuthentication();
        GlobalConfiguration.Configuration.Filters.Add(new HostAuthenticationFilter(OAuthOptions.AuthenticationType));

选中此No OWIN authentication manager is associated with the request但无效

我能够在我的电脑上重现它。只需重新启动应用程序域并向api发送请求即可。我会得到上述错误。之后一切都会好起来的。这是我本地机器的StackTrace，

我没有使用SPA模板中提供的OAuth服务器。

config.SuppressDefaultHostAuthentication();
config.Filters.Add(new HostAuthenticationFilter(Startup.OAuthOptions.AuthenticationType));

Answer 1

修复方法是使用Microsoft.AspNet.WebApi.Owin（UseOwinMethod）。这也修复了Server cannot append header after HTTP headers have been sent.。我在这个软件包中发现了一个bug，它也可以解决Why MessageHandler is executing in MVC request? 相关http://katanaproject.codeplex.com/discussions/540202

Answer 2

我正在使用第三方基本身份验证中间件（Thinktecture.IdentityModel.Owin.BasicAuthentication）并且遇到与OP相同的错误。我总是提到Microsoft.Owin.Host.SystemWeb。

最终，我在App_Start代码中忽略了这些行：

config.SupressDefaultHostAuthentication();
config.Filters.Add( new HostAuthenticationFilter("") );

删除这两行后，它按预期工作。

Answer 3

您是如何尝试访问API中的owin上下文的？在WebApi中，您应该使用Request.GetOwinContext（）（而不是在MVC中使用的HttpContext.GetOwinContext（））。

Elmah显示，“没有OWIN身份验证管理器与请求相关联。”
