ColdFusion onSessionEnd 问题
我读过很多对 onSessionEnd 有问题的人的帖子。这是我第一次将 application.cfm 转换为 application.cfc,并且 onSessionEnd 无法与我尝试调用的 CFFunction 一起使用。
我想问题在于如何从组件所在的 /lib/components/ 文件夹中正确调用该组件。
当用户登录时,我正在创建一个会话数组,用于跟踪该作业中的 jobNumber 和 last_completed_step 。用户会话中有多个作业。在会话结束时,我想将更新的数组数据写回数据库。
我应该明确指出,目前我查看日志文件并看到会话已启动 - 如下所示的 onSessionStart 中的编码。此外,当我取出组件的调用时,onSessionEnd也会写入日志文件。换句话说,如果我只是告诉它写“会话结束”。到日志文件我会在日志文件中看到它。我已在 CF Administrator 和 app.cfc 中将当前会话超时设置为 3 分钟以进行测试。
如果我从单独的文件(也在根级别)调用 jobState.cfc 中的“giveMeAnswer”方法,giveMeAnswer 方法将正常工作并返回值“我是 CFC”。
如果我将 jobState.cfc 移动到根级别并将组件属性设置为“jobState”,我也会从组件获得返回。
<!--- Runs when your session starts --->
<cffunction name="onSessionStart" returnType="void" output="false">
<!--- :: invoke all session variables | moved out of on session start :: --->
<cfinvoke component="#application.virtualPaths.cfcPath#system/sessionVars" method="init" />
<cflog file="#This.Name#" type="Information" text="Session started.">
</cffunction>
<!--- Runs when session times out --->
<cffunction name="onSessionEnd" returntype="void">
<cfargument name="SessionScope" type="struct" required="true" />
<cfargument name="ApplicationScope" type="struct" required="true" />
<cfinvoke component="/lib/components/jobState" method="giveMeAnswer" returnvariable="returnFromCfc">
</cfinvoke>
<cflog file="#This.Name#" type="Information" text="Session ended. #returnFromCfc#">
<cfreturn />
</cffunction>
那么,只是没有找到该组件吗?还有其他想法吗?
非常感谢,杰瑞
I have read many posts by people who have problems with onSessionEnd. This is my first conversion of application.cfm to application.cfc and the onSessionEnd is not working with the CFFunction I am trying to invoke.
I guess what's hanging this up is how to properly call the component from the /lib/components/ folder where it resides.
When a user logs in I am creating a session array that tracks a jobNumber and the last_completed_step in that job. There are multiple jobs in a users session. At the end of the session I want to write the updated array data back to the DB.
I should make it clear that at present I look into my log file and see that the session is started - as coded in the onSessionStart shown below. Furthermore, the onSessionEnd also writes to the log file when I take out the invocation of the component. In other words if I just tell it to write "Session ended." to the log file I will see it in the log file. I have set current session timeout in CF Administrator and my app.cfc for 3 minutes for testing.
If I call the "giveMeAnswer" method in the jobState.cfc from a separate file (also at the root level) the giveMeAnswer method works properly and returns the value "I am a CFC."
If I move the jobState.cfc to the root level and set the component attribute to "jobState" I am also getting a return from the component.
<!--- Runs when your session starts --->
<cffunction name="onSessionStart" returnType="void" output="false">
<!--- :: invoke all session variables | moved out of on session start :: --->
<cfinvoke component="#application.virtualPaths.cfcPath#system/sessionVars" method="init" />
<cflog file="#This.Name#" type="Information" text="Session started.">
</cffunction>
<!--- Runs when session times out --->
<cffunction name="onSessionEnd" returntype="void">
<cfargument name="SessionScope" type="struct" required="true" />
<cfargument name="ApplicationScope" type="struct" required="true" />
<cfinvoke component="/lib/components/jobState" method="giveMeAnswer" returnvariable="returnFromCfc">
</cfinvoke>
<cflog file="#This.Name#" type="Information" text="Session ended. #returnFromCfc#">
<cfreturn />
</cffunction>
So, is it just not finding the component? Any other ideas?
Thanks much, Jerry

我知道我以前见过人们在组件调用中使用 / ,但我不相信它得到官方支持。您想要使用点符号路径,ala
component="lib.components.jobstate"
并确保 lib 是子目录或指向 lib 文件夹的已知 CF 映射。
I know I've seen folks use / in component calls before, but I do not believe it is officially supported. You want to use a dot notation path instead, ala
component="lib.components.jobstate"
and assure that lib is either a subdirectory or a known CF mapping that points to the lib folder.
