【中文标题】System.Web.Routing.UrlRoutingModule 未实现 IHttpHandlerFactory 或 IHttpHandler【英文标题】：System.Web.Routing.UrlRoutingModule does not implement IHttpHandlerFactory or IHttpHandler 【发布时间】：2017-02-28 20:54:55 【问题描述】：在我们的网站中，此错误每 5 分钟出现一次。 我不知道它从哪里来的。 任何人都可以帮助我们吗？ 我们需要没有此错误的 robots.txt。
我们的应用程序自动调用http://www.xyzName.com/content/images/thumbs/robots.txt 并在异常下方显示
System.Web.Routing.UrlRoutingModule 没有实现 IHttpHandlerFactory 或 IHttpHandler。
描述：执行过程中发生了未处理的异常 当前的网络请求。请查看堆栈跟踪以获取更多信息 有关错误的信息以及它在代码中的来源。
这是调用该方法时自动生成robots.txt文件的方法。但问题出在应用程序 robots.txt 自动调用的某个位置。

在 RouteProvider 中，我们添加下面的行来映射路线。
routes.MapRoute("robots.txt","robots.txt",new controller = "Common", action ="RobotsTextFile" ,new[] "Nop.Web.Controllers" );
每 5 分钟播放一次。我们使用亚马逊服务器作为 CDN，从那里获取图像。
亚马逊有没有可能称这个“http://www.xyzName.com/content/images/thumbs/robots.txt”网址？
【问题讨论】：
但我们需要 robots.txt 文件 我需要把那行放在哪里......？紧跟在 对不起先生，不工作... :( 取消注释从您的 web.config 中删除（或注释掉）这一行用于生成 robot.txt
<add name="RobotsTxt" path="robots.txt" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
并取消注释以下行
<remove name="UrlRoutingModule-4.0" />
<add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
希望这会有所帮助！

【参考方案2】：在最近发布了我最近更改了程序集名称的 Web API 后，我遇到了同样的问题。我没有 robots.txt 文件，所以上述答案与我无关。无论如何，作为一个解决方案，我只是清理了服务器上的文件夹并重新发布。

【参考方案3】：我在重新部署到 Server 2016 时也遇到了这个问题。最后，我实际上注释掉了 URLRoutingModule 的处理程序映射并且它起作用了。我的猜测是它与机器级别上已经设置的内容冲突。
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
<!--<remove name="UrlRoutingModule-4.0"/>
<add name="UrlRoutingModule-4.0" path="*" verb="*" type="System.Web.Routing.UrlRoutingModule" preCondition=""/>-->
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
