我收到错误消息“调用 CFC componentname.cfc 时出错：在组件 ..\filepath\Application.cfc 中找不到 onRequest 方法”。

这适用于 CF8，但不适用于具有相同代码的 CF9。两种环境都使用 Apache 和 Fusebox 5。onRequest 方法存在于 application.cfc 中。

请帮忙。

CFC 绑定代码：

<cfselect name="officeNum" id="officeNum" bind="cfc: userYODSU.GetOfficeList({empID},{fy})" display="officeNameTxt" value="officeNum" bindOnLoad="true"><option value="">---</option></cfselect>

APPLICATION.CFC 中的代码

<cfcomponent output="false">
    <cfprocessingdirective suppresswhitespace="true">

            Fusebox 4.1 did not set attributes.fuseaction or default the fuseaction variable until
            *after* fusebox.init.cfm had run. This made it hard for fusebox.init.cfm to do URL
            rewriting. For Fusebox 5, we default the fuseaction variable and set attributes.fuseaction
            before fusebox.init.cfm so it can rely on attributes.fuseaction and rewrite that. However,
            in order to maintain backward compatibility, we need to allow fusebox.init.cfm to set
            attributes[_fba.fuseactionVariable] and still have that reflected in attributes.fuseaction
            and for that to actually be the request that gets processed.

我不知道为什么你会得到你所看到的错误，但是在 CF9 中你不需要在 delete 周围做所有的事情onRequest()，你可以简单地onCfcRequest()在那里有一个方法，它会被调用而不是onRequest()在请求时调用制造氟氯化碳。这样做可以消除出现错误情况的情况。

最后我能够解决这个问题。我认为该错误仅显示在本地主机中，但未显示在任何服务器上。另外，发现问题只出在带有bind cfc的cfselect上。我没有看到 localhost 和其他服务器中的设置有任何区别。所以我尝试对保险丝盒代码进行一些更改并修复它。在 fusebox5.cfm 更改后使其工作。

<cftry>
    <cfset __fuseboxAppCfc.onRequest(CGI.SCRIPT_NAME) />
    <cfset __fuseboxAppCfc.onRequestEnd(CGI.SCRIPT_NAME) />
    <cfcatch type="any">
        <cfset __fuseboxAppCfc.onError(cfcatch)>
    </cfcatch>
</cftry>

将其更改为：

<cftry>
    <cfif right(CGI.SCRIPT_NAME,"4") NEQ ".cfc">
        <cfset __fuseboxAppCfc.onRequest(CGI.SCRIPT_NAME) />
    </cfif>
    <cfset __fuseboxAppCfc.onRequestEnd(CGI.SCRIPT_NAME) />
    <cfcatch type="any">
        <cfset __fuseboxAppCfc.onError(cfcatch)>
    </cfcatch>
</cftry>
