移至IIS7服务器后出现Signalr 404错误

Question

当托管在IIS 8中时，我有一个信号器服务在我的开发环境上运行良好。

使用IIS 7.5将服务移至我们的质量检查服务器时，尝试连接到我的集线器会导致此错误：

System.AggregateException: One or more errors occurred. ---> Microsoft.AspNet.SignalR.Client.HttpClientException: StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

我的创业班

[assembly: OwinStartup(typeof(SignalRStartup))]

  public class SignalRStartup
  {
    public void Configuration(IAppBuilder app)
    {
      app.MapSignalR("/restricted/signalr", new HubConfiguration());
    }
  }

并尝试在C＃客户端中启动连接

HubConnection foo = new HubConnection("http://localhost/ccwebdev/restricted");
foo.Start().Wait();

质量检查服务器正在运行Windows Server 2008 R2 SP1，因此它应支持无扩展名的URL。

我还尝试将其添加到我的web.config <modules runAllManagedModulesForAllRequests="true"/>

应用程序池处于集成模式，而不是经典模式

我在这里阅读了许多其他类似的SO文章和404的故障排除指南： http ： //www.asp.net/signalr/overview/signalr-20/troubleshooting-and-debugging/troubleshooting#other ，但是没有运气。

谁能提供我可以尝试的其他任何疑难解答步骤？

将地图调用更改为app.MapSignalR("/restricted", new HubConfiguration()); 导致在服务启动时引发异常

您是否尝试手动修补服务器以获取无扩展名的URL？ 我不确定服务器2008 R2 SP1是否包含该修补程序-您可以尝试一下：
