错误的ColdFusion 10俘获

和我通过一些可用的价值观很感兴趣，但我使用的onError功能脚本Application.cfc。错误的ColdFusion 10俘获

根据learn.adobe.com，cferror有一个诊断错误变量以及一些其他有趣的位，如error.remoteAddress和error.generatedContent。

问：如果我在scripted Application.cfc中使用onError，那么如何获得诊断错误变量（以及其他错误）？

编辑：你确切地使用onError？

public void function onSessionStart() { 
    session.TryCatch = 3; 
} 

public boolean function onRequestStart(String targetPage){ 
    request.TickCount = GetTickCount(); 
    request.LogDBSort = 0; 
    return true; 
} 

public void function onError(Exception,EventName) { 
    if (StructKeyExists(session,"TryCatch") && session.TryCatch) { 
     session.TryCatch -= 1; 
     if (StructKeyExists(Exception,"Message")) { 
      WriteOutput("It looks like you got the following ColdFusion error:<blockquote>" 
       & Exception.Message 
       & "</blockquote>" 
      ); 
      local.LogCFErrMessage = Exception.Message; 
     } else { 
      local.LogCFErrMessage = "No Exception.Message"; 
     } 
     param request.TickCount = GetTickCount(); 
     param request.LogDBSort = -999; 
     request.LogDBSort += 1; 

     if (StructKeyExists(Exception,"Name")) { 
      local.LogCFErrName = Exception.Name; 
     } else { 
      local.LogCFErrName = "No Exception.Name"; 
     } 
     if (StructKeyExists(Exception,"Detail")) { 
      local.LogCFErrDetail = Exception.Detail; 
     } else { 
      local.LogCFErrDetail = "No Exception.Detail"; 
     } 
     if (StructKeyExists(Exception,"Number")) { 
      local.LogCFErrNumber = Exception.Number; 
     } else { 
      local.LogCFErrNumber = "No Exception.Number"; 
     } 
     if (StructKeyExists(Exception,"Type")) { 
      local.LogCFErrType = Exception.Type; 
     } else { 
      local.LogCFErrType = "No Exception.Type"; 
     } 
     if (StructKeyExists(Exception,"EventName")) { 
      local.LogCFErrEventName = Exception.EventName; 
     } else { 
      local.LogCFErrEventName = "No Exception.EventName"; 
     } 
     local.svc = new query(); 
     local.sql = "

     "; 
     local.svc.setSQL(local.sql); 
     local.svc.addParam(cfsqltype="CF_SQL_VARCHAR",value=Left(local.LogCFErrName,512));

      local.svc = new mail(); 
      local.svc.setSubject(GetApplicationMetaData().Name & ': ' & ListLast(GetBaseTemplatePath(),'\')); 
      local.msg = LogCFErrMessage; 
      local.svc.setBody(local.msg); 

      local.svc.setServer(Application.Home.Email.Server); 
      local.svc.setType(Application.Home.Email.Type); 
      local.svc.setUseSSL(Application.Home.Email.UseSSL);

      local.svc.setTo(Application.Home.Email.UserName); 
      local.svc.Send(); 
      WriteOutput("I've sent an email to the administrator to let them know."); 
     } 
    } 
}

确切地说你是如何使用onError？ –

（编辑 - 我没有时间写一个答案，但是...）大多数这些值（远程地址，等等）都是简单的请求参数[可以通过多种方式获得，例如通过GetHTTPRequestData（），CGI作用域，等等]（http://www.stephenwithington.com/blog/index.cfm/2008/8/26/CGI-Variables-and-Their-Respective-ColdFusionJava-Servlet-Alternative-Methods）。我相信“消息”类似于“诊断”，只是减去行号，可以从Error.TagContent.Line中获得。 – Leigh

@Leigh，这是一个非常有用的链接！谢谢！ –

我使用arguments.exception。这是一个例子。

<cffunction name="onError"> 
<cfargument name="Exception" required=true type="any"> 
more code 

<cfmail to="#recipients#" 
from="#recipients#" 
subject="Error on whatever" type="html"> 

<p>Error Occurred #now()#</p> 
<cfdump var="#Arguments.Exception#" label="exception"> 
<cfdump var="#request#" label="request"> 
<cfdump var="#cgi#" label="cgi"> 
</cfmail>
