如何向 ColdFusion 异常对象添加属性

我知道这看起来一定是一个非常人为的例子，但我有一个情况，在一个 catch 中我将尝试/捕获另一个异常。但是，我想在第二个捕获中包含有关第一个异常的信息。理想情况下，它看起来像这样：

try {
  a = b;
}
catch ( any e ) {
  local.originalException = Duplicate(e);
  try  {
     throw "New exception!!!";
  }
  catch( any e )    {
     e.originalException = local.originalException;
     doNotification( e );
  }
}

当我运行这个小测试时，设置 e.originalException 时不会发生意外异常，但是，当我在设置后立即转储异常时，它不是异常结构的一部分。也许还有另一种方法可以实现这一目标吗？我用的是ACF 9。

I know this must seem like a very contrived example, but I have a case in which within a catch I will be try/catching another exception. However, I would like to include information in the second catch about the first exception. Ideally it would look something like this:

try {
  a = b;
}
catch ( any e ) {
  local.originalException = Duplicate(e);
  try  {
     throw "New exception!!!";
  }
  catch( any e )    {
     e.originalException = local.originalException;
     doNotification( e );
  }
}

When I run this little test, there is no unexpected exception that occurs when setting e.originalException, however, when I dump the exception immediately after setting it, it is not a part of the exception struct. Is there perhaps another way to achieve this? I am using ACF 9.

不幸的是，您实际上无法将太多附加信息“附加”到 CF 异常。但是你可以做这样的事情来将一个异常包装在另一个异常中......

<cftry>
<cfset a = b>
<cfcatch>
    <cftry>
        <cfthrow message="new exception" extendedinfo="#serializeJson(cfcatch)#">
        <cfcatch>
            <cfset stOriginalExceptionData = deserializeJson(cfcatch.extendedInfo)>
            <cfdump var="#stOriginalExceptionData#">
        </cfcatch>
    </cftry>
</cfcatch>

这种技术对你有帮助吗？

You can't really "attach" much additional info to a CF exception, unfortunately. But you could do something like this to wrap up one exception in another one...

<cftry>
<cfset a = b>
<cfcatch>
    <cftry>
        <cfthrow message="new exception" extendedinfo="#serializeJson(cfcatch)#">
        <cfcatch>
            <cfset stOriginalExceptionData = deserializeJson(cfcatch.extendedInfo)>
            <cfdump var="#stOriginalExceptionData#">
        </cfcatch>
    </cftry>
</cfcatch>

Does this sort of technique help you?

您是否尝试过复制该对象？因为根据文档，您无法修改 cfcatch 异常：

已更改的对象修改：您无法修改由
cfcatch

我知道我回答“有点”晚了，但我遇到了同样的问题，这就是我解决它的方法：

<cfscript>
try {
  a = b;
}
catch ( any e ) {
  local.originalException = Duplicate(e);
  try  {
     throw "New exception!!!";
  }
  catch( any e )    {
    local.e = deserializeJson(serializeJson(e));
    local.e.originalException = local.originalException;
    writeDump(local.e);
  }
}
</cfscript>

I know I'm a "bit" late to answer, but I ran into the same issue and this is how I got around it:

<cfscript>
try {
  a = b;
}
catch ( any e ) {
  local.originalException = Duplicate(e);
  try  {
     throw "New exception!!!";
  }
  catch( any e )    {
    local.e = deserializeJson(serializeJson(e));
    local.e.originalException = local.originalException;
    writeDump(local.e);
  }
}
</cfscript>
