如何覆蓋ServiceStack中的默認404頁面？

Question

我正在使用ServiceStack，並有我自己的處理程序來處理拋出的任何異常，這些異常都很好用。但是，我似乎無法找出如何覆蓋從ServiceStack返回的默認404錯誤頁面。目前Body看起來像這樣：

Handler for Request not found: 


Request.ApplicationPath:/
Request.CurrentExecutionFilePath: /Test/123 
Request.FilePath: /Test/123 
Request.HttpMethod: GET 
Request.MapPath('~'): C:\Test-Web\src\Web.Service\ 
Request.Path: /Test/123 
Request.PathInfo: 
Request.ResolvedPathInfo: /Test/123 
Request.PhysicalPath: C:\Test-Web\src\Web.Service\Test\123 
Request.PhysicalApplicationPath: C:\Test-Web\src\Web.Service\ 
Request.QueryString: 
Request.RawUrl: /Test/123 
Request.Url.AbsoluteUri: http://localhost:65079/Test/123 
Request.Url.AbsolutePath: /Test/123 
Request.Url.Fragment: 
Request.Url.Host: localhost 
Request.Url.LocalPath: /Test/123 
Request.Url.Port: 65079 
Request.Url.Query: 
Request.Url.Scheme: http 
Request.Url.Segments: System.String[] 
App.IsIntegratedPipeline: False 
App.WebHostPhysicalPath: C:\Test-Web\src\Web.Service 
App.WebHostRootFileNames: [extensions.cs,global.asax,global.asax.cs,Web.Service.csproj,Web.Service.csproj.user,Web.Service.ncrunchproject,packages.config,servicestack.common.dll,servicestack.common.pdb,servicestack.common.xml,servicestack.interfaces.dll,servicestack.interfaces.pdb,servicestack.interfaces.xml,servicestack.redis.dll,web.config,web.debug.config,web.release.config,bin,dto,exceptions,interfaces,mongo,obj,pipeline,properties,resources,serialization,servicestack,supporting,validators,windsor] 
App.DefaultHandler: metadata 
App.DebugLastHandlerArgs: GET|/Test/123|C:\Test-Web\src\Web.Service\Test\123 

顯然是一個404狀態碼。

任何幫助或方向，我需要重寫或更改將不勝感激。如果您還需要我的進一步詳情，請隨時詢問，我會盡快回復。

默認404處理程序的源代碼可以在這裏找到： https://github.com/ServiceStack/ServiceStack/blob/master/src/ServiceStack/WebHost.Endpoints/Support/NotFoundHttpHandler.cs。

您的自定義404處理器需要實現IServiceStackHttpHandler和IHttpHandler：

public class YourNotFoundHandler : IServiceStackHttpHandler, IHttpHandler 
{ 
    public void ProcessRequest(IHttpRequest request, IHttpResponse response, string operationName) 
    { ... } 

    public void ProcessRequest(HttpContext context) 
    { ... } 
} 

要覆蓋默認404處理器在AppHost.Configure()方法：

SetConfig(new EndpointHostConfig { 
    CustomHttpHandlers = { { HttpStatusCode.NotFound, new YourNotFoundHandler() } } 
});
