没有OWIN认证管理器与请求相关联 [英] No OWIN authentication manager is associated with the request

问题描述

试图启用owin＆放后; ASPNET身份到我的网络API项目（在VS 2013 +净4.5.1）我得到了每个有效或unvalid以下错误（请求没有这样的控制器）的请求：

 ＆LT;错误＆GT;
＆LT;消息方式＆gt;发生错误＆LT; /信息＆GT;
＆LT; ExceptionMessage＆GT;
没有OWIN认证管理器与请求相关联。
＆LT; / ExceptionMessage＆GT;
＆LT; ExceptionType＆GT; System.InvalidOperationException＆LT; / ExceptionType＆GT;
＆LT;＆栈跟踪GT;
在System.Web.Http.Owin.PassiveAuthenticationMessageHandler.Sup$p$pssDefaultAuthenticationChallenges(Htt$p$pquestMessage要求）在System.Web.Http.Owin.PassiveAuthenticationMessageHandler＆LT; SendAsync＆GT; d__0.MoveNext（）---从previous位置堆栈跟踪，其中引发异常---在System.Runtime.CompilerServices.TaskAwaiter结束.ThrowForNonSuccess（任务任务）在System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）在System.Runtime.CompilerServices.TaskAwaiter`1.GetResult（）在System.Web.Http.HttpServer＆LT; SendAsync＆GT; d__0.MoveNext （）
＆LT; /堆栈跟踪＆GT;
＆LT; /错误＆GT;
 

我在调试模式下检查，没有异常被处理过！我也意识到，配置在启动类不会被调用（实际上从未被抓调试器）。这里是code的启动：

  [汇编：OwinStartup（typeof运算（bloob.bloob.Startup））]命名空间bloob.bloob
{
    公共部分类启动
    {
        公共无效配置（IAppBuilder应用程序）
        {
            ConfigureAuth（应用）;
        }
    }
}
 

解决方案

我发现这个问题终于来了！通过线与新创建的项目比较行，发现没有什么区别后，我查了这两个项目的参考，是的......所有的问题是缺少从包！

  Microsoft.Owin.Host.SystemWeb
 

我不知道为什么这个包装在包安装阶段错失但奇怪的一点是，为什么没有任何构建抛出的异常？或者没有任何dll引用错误？

After trying to enable owin & AspNet Identity to my Web Api project (in VS 2013 + .Net 4.5.1) I get the following error in each valid or unvalid(request to none exist controller) requests :

<Error>
<Message>An error has occurred.</Message>
<ExceptionMessage>
No OWIN authentication manager is associated with the request.
</ExceptionMessage>
<ExceptionType>System.InvalidOperationException</ExceptionType>
<StackTrace>
at System.Web.Http.Owin.PassiveAuthenticationMessageHandler.SuppressDefaultAuthenticationChallenges(HttpRequestMessage request) at System.Web.Http.Owin.PassiveAuthenticationMessageHandler.<SendAsync>d__0.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at System.Web.Http.HttpServer.<SendAsync>d__0.MoveNext()
</StackTrace>
</Error>

As I checked in debug mode, no exception is handled too! Also I realized that Configuration in Startup class is never called (indeed never caught by the debugger). here is the code for startup :

[assembly: OwinStartup(typeof(bloob.bloob.Startup))]

namespace bloob.bloob
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }
}

解决方案

I found the problem finally! After comparing line by line with a newly created project and finding no difference , I checked references on both projects and yes!... All the problem was from missing package :

Microsoft.Owin.Host.SystemWeb

I don't know why this packaged is missed in package installation phase but the strange point is that why didn't any build exception thrown? or no any dll reference error?
