Question

我试图在我现有的MVC5项目上安装ElmahR。在安装ElmahR之前，我使用Elmah和NLog来处理异常。基于此tutorial我使用nuget包安装了ElmahR

Install-Package ElmahR.Elmah

然后在web.config中，我更改了这一行：

<errorPost targetUrl="http://TARGET_DASHBOARD_URL" sourceId="SOURCE_IDENTIFIER_URI_AS_LISTED_IN_DASHBOARD_CONFIG" secret="SECRET_PASSPHRASE_(SPECIFY_JUST_IN_CASE_OF_ENCRYPTED_POST)" />

到

<errorPost targetUrl="http://localhost:62335/posterror.axd" sourceId="MyCode" />

下一步我安装了仪表板

Install-Package ElmahR.Modules.Dashboard

并改变了这一行：

<application name="Sample application" sourceId="SomeCode" infoUrl="http://localhost:12345/elmah.axd" testExceptionUrl="http://localhost:12345/elmah.axd/test" />

到

<application name="WPS" sourceId="MyCode" infoUrl="http://localhost:62335/elmah.axd" testExceptionUrl="http://localhost:62335/elmah.axd/test" />

在HomeController（Index）中，我按throw new exception("Test ElmahR");和Run生成错误。然后我转到http://locahost:62335/elmahr/dashboard并看到没有异常捕获，但如果我看到http://localhost:62335/elmah它捕获了错误＆＃34; Path＆＃39; /posterror.axd'找不到＆＃34;不测试ElmahR。为什么呢？

更新1

作为@Wasp的建议，我在system.web和system.webServer注册了Elmah模块和处理程序，但仍未解决问题：

<system.web>
  ...
  <httpHandlers>
    <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
  </httpHandlers>
  ...
</system.web>

<system.webServer>
  ...
  <handlers>
    <add name="Elmah" verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
  </handlers>
  ...
</system.webServer>

Answer 1

如果您不使用IIS（完整版或快速版），则可能会遇到此问题，因为我在system.web/httpHandlers中没有看到web.config部分，您将在此处声明丢失posterror.axd 1}}端点。端点位于system.webserver/handlers部分，但需要IIS。你检查过了吗？

ElmahR没有发现任何异常
