我遇到一个问题,其中onError方法在我的application.cfc文件中不再起作用。该程序昨天捕获了错误并正确显示error.cfm,但现在我只收到500错误。我的经理昨天可能已更改了文件中的几项内容,但我们似乎已重新创建了该文件,但未解决任何问题。
我目前使用onError,但尝试了cferror。使用cferror,数据输入表单甚至都不会加载。
代码如下。 onError被阻止,因为我正在使用cferror代码显示它。只需删除cferror并阻塞即可,如果要使用它将onError:
<!--- this component controls the application's global settings / event
handlers and maintains user sessions --->
<cfcomponent>
<!--- define some basic settings --->
<cfset this.name = "QualityDataPortal" />
<cfset this.sessionManagement = "yes" />
<cfset this.setClientCookies = "no" />
<cfset this.loginStorage = "session" />
<!--- this function is triggered when our application is initialized --->
<cffunction name="onApplicationStart" access="public" returntype="boolean" output="no">
<!--- define application variables --->
<cfset application.dataSource = 'quality' />
<!--- return out --->
<cfreturn true />
</cffunction>
<cferror
template="error.cfm"
type="exception"
mailTo="[email protected]" />
<!--- <!--- this function is triggered when coldfusion encounters an error --->
<cffunction name="onError" access="public" returntype="void" output="no">
<cfargument name="exception" required="yes">
<cfargument name="eventname" type="string" required="yes">
<!--- send a dump of the error via email --->
<cfmail from="[email protected]" to="[email protected]" subject="Quality Data Portal Error Encountered" type="html">
<cfoutput>
The following error was encountered on #dateformat(now(), 'dddd mmmm dd, yyyy')# at #timeformat(now(), 'hh:mm:ss tt')#<br /><br />
<cfdump var="#arguments.exception#">
<cftry><cfdump var="#arguments#"><cfcatch></cfcatch></cftry>
<cfdump var="#form#">
<cfdump var="#session#">
<cfdump var="#cgi#">
</cfoutput>
</cfmail>
<!--- alert the user that an error has been encountered --->
<cflocation url="error.cfm" addtoken="no">
<cfabort />
</cffunction> --->
<!--- this function is triggered when coldfusion receives a request for a template it cannot locate --->
<cffunction name="onMissingTemplate" access="public" returntype="void" output="no">
<cfargument name="targetPage" type="string" required="yes">
<!--- alert the user that the page they requested could not be found --->
<cflocation url="404.cfm" addtoken="no">
<cfabort />
<!--- return out --->
<cfreturn />
</cffunction>
</cfcomponent>
最佳答案
我建议,这样可以更好地看到,删除未使用的代码(cferror标记),删除不必要的注释,不要嵌套注释。
然后,从onError
的此代码开始
<cffunction name="onError" returntype="void" output="false">
<cfargument name="exception" required="true">
<cfargument name="eventname" type="string" required="true">
<cfmail to="[email protected]" from="[email protected]" subject="Quality Data Portal Error Encountered" type="html">
<cfoutput>The following error was encountered on #DateFormat(now(), "dddd, mmmm dd, yyyy")# at #TimeFormat(now(), "HH:nn:ss")#</cfoutput>
<hr />
<cfdump var="#exception#" label="Exception" />
<cfdump var="#form#" label="Form" />
<cfdump var="#session#" label="Session" />
<cfdump var="#cgi#" label="CGI" />
</cfmail>
<cflocation url="error.cfm" addtoken="false" />
</cffunction>
注意:
请注意:
#timeformat(now(), 'hh:mm:ss tt')
,应在几分钟内使用nn
而不是mm
。<cflocation ...
之后没有代码,因为ColdFusion不会运行它。停止执行当前页面并打开ColdFusion页面或HTML文件。
