Question

我刚开始使用ELMAH，但我想尝试将GUID传递给错误页面。

我尝试了this文章所讨论的内容，但我无法触发ErrorLog_Logged。任何想法为什么会发生这种情况。我是否需要在web.config文件中添加一些其他配置？（对不起提前格式化下面的代码，无法正确显示）。

谢谢，

以下是我的web.config文件的内容：

<?xml version="1.0"?>
<configuration>
<configSections>
<sectionGroup name="telerik.web.ui">
        <section name="radScheduler" type="Telerik.Web.UI.RadSchedulerConfigurationSection, Telerik.Web.UI" allowDefinition="MachineToApplication" requirePermission="false"/>
        <section name="radCompression" type="Telerik.Web.UI.RadCompressionConfigurationSection, Telerik.Web.UI, PublicKeyToken=121fae78165ba3d4" allowDefinition="MachineToApplication" requirePermission="false"/>
    </sectionGroup>
<sectionGroup name="elmah">
  <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah"/>
  <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />
  <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" />
  <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah"/>
</sectionGroup>

以下是我的global.asax文件

的内容

void ErrorLog_Logged(object sender, ErrorLoggedEventArgs args)
{
    //if (args.Entry.Error.Exception is HandledElmahException)
    //    return;

    var config = WebConfigurationManager.OpenWebConfiguration("~");
    var customErrorsSection = (CustomErrorsSection)config.GetSection("system.web/customErrors");

    if (customErrorsSection != null)
    {
        switch (customErrorsSection.Mode)
        {
            case CustomErrorsMode.Off:
                break;
            case CustomErrorsMode.On:
                FriendlyErrorTransfer(args.Entry.Id, customErrorsSection.DefaultRedirect);
                break;
            case CustomErrorsMode.RemoteOnly:
                if (!HttpContext.Current.Request.IsLocal)
                    FriendlyErrorTransfer(args.Entry.Id, customErrorsSection.DefaultRedirect);
                break;
            default:
                break;
        }
    }
}

void FriendlyErrorTransfer(string emlahId, string url)
{
    Response.Redirect(String.Format("{0}?id={1}", url, Server.UrlEncode(emlahId)));
}

在你的web.config中确保你有

<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />

即

<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
  <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
  <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" preCondition="managedHandler" />
  <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" preCondition="managedHandler" />
</modules>

同时添加

Elmah.ErrorLogModule logModule = new Elmah.ErrorLogModule();
logModule.Logged += new Elmah.ErrorLoggedEventHandler(logModule_Logged);
Elmah.ErrorSignal.FromCurrentContext().Raise(ex);

到您的Application_Error功能。
