如何重置会话变量 [英] How to reset session variables

问题描述

我正在开发一个应用。在CF10中。已经确定该应用。将通过在点网应用中创建的链接打开。
用户登录&通过点网应用程序退出以查看链接。当用户单击该链接时，他们可以访问CF应用程序。

I'm developing an app. in CF10. It's been decided that this app. will be opened through a link that is created in a dot net app. Users log in & out through the dot net application in order to see the link. When users click on that link they can access the CF application.

此链接传递了一个用户ID，我正在使用该用户ID创建session.userid
在application.cfc的onSessionStart中：

This link passes a user id, I'm using this user id to create session.userid in onSessionStart at application.cfc :

  <cfset session.userid = #Trim(URL.userid)#> 

问题是，当我注销并以其他用户身份重新登录时，上一次会话。用户名仍然存在。所以我有两个不同的session.userids
为了避免这种情况，我想我可以做以下事情：

The problem is, when I log out and log back in as a different user, my previous session.userid still exists. So I have two different session.userids In order to avoid this I thought I can do the following:

在application.cfc的onSessionStart中，我从sessionIvalidate函数：

in onSessionStart at application.cfc, I start with sessionIvalidate function:

   <cfset sessionInvalidate() />
   <cfset session.userid = #Trim(URL.userid)#>

我以为每次应用程序启动application.cfc ColdFsuion必须通过application.cfc运行，然后sessionInvalidate函数将清除现有的session.userid，然后创建一个新的session.userid，因此，如果我以与同一台计算机不同的用户身份登录和注销，则该应用程序仍将保留一个session.userid。
但不幸的是，这种方法不起作用！在没有创建新会话的情况下，我仍然可以使用较旧的会话！

I thought every time the application start application.cfc ColdFsuion has to run through application.cfc then sessionInvalidate function will clean out existing session.userid then a new one is created so if I log in and out as a different users from the same computer then the application still maintains one session.userid. But unfortunately this approach does not work! I still get the older session while the new session is not created!

如果我无法使用此逻辑来做到这一点，哪种方法最好呢？
我应该重新设置session.userid index.cfm吗？

What is the best approach to my situation if I can't do it using this logic. Should I re-set session.userid index.cfm instead?

推荐答案

使用注销顺序运行2单独的会话驱逐舰。这样我知道会话已被破坏。

With my log out sequence I run 2 separate session destroyers. This way I know the session is destroyed.

<cfset structClear( session ) />
<cfset sessionInvalidate()/>

我正在运行CF11，当我的客户从我的Web应用程序注销时，它的运行效果很好。

I am running CF11 and this works beautifully when my customers log out of my web application.

至于CFLOCK，取决于您使用的CF版本，将取决于您是否使用它。它在CF11中已贬值，当我进入CF11时，它破坏了我的应用程序。

As for the CFLOCK, depending on your version of CF will depend on if you use it. It's been depreciated in CF11 and when I went to CF11, having it broke my application.
