ColdFusion 8- Application.cfc干扰

Question

我刚刚遇到了一个客户网站的奇怪问题，我的实时域名正在使用我的开发域名应用程序设置。我以前没有遇到过这个问题，删除Application.dsn周围的cflock (以及其他设置)解决了这个问题。

如前所述，我有一个实时站点*www.*和一个开发站点*dev.*，我的开发站点位于实时站点/dev/的子文件夹中，并且有自己的Application.cfc。

我的第一个问题是，如果我的Application作用域中的变量在dev文件夹中，这会覆盖上面文件夹中的Application作用域变量吗？它会认为它的范围是一样的吗？如果是这样，那么这可能解释了问题是什么，如果不是，那么我就被难住了。

我的第二个问题是，我应该如何更正application.cfc中的cflock应用程序范围变量？我真的应该这么做吗？

这是我的Application.cfc，非常感谢你的建议：

Answer 1

为什么要根据应用程序所处的环境更改应用程序名称？这没有任何意义。应用程序仍然是相同的应用程序，无论它是在prod中，还是您正在测试或开发它。

同样，源代码也是如此。你已经把你的开发网站放在你的网站上了吗？这有什么意义呢？

我不知道您的应用程序变量发生了什么，但它们绑定到应用程序名称(this.name)，而不是Application.cfc在目录结构中的位置。

我怀疑你的零applicationTimeout在这里帮不了什么忙。这基本上意味着你的应用程序永远不会真正持久...它将使每个请求超时。这也没有任何意义。

您不需要在onApplicationStart()中<cflock>该代码。ColdFusion将只允许一个请求运行onApplicationStart()：所有其他请求都将排队等待，直到它完成，此时应用程序已经启动，因此排队的请求甚至不会尝试运行它。

我认为你的问题很可能是由你糟糕的应用程序框架设计引起的，你正在做的这种奇怪的事情是将dev和prod放在同一个源代码树中(这违背了所有的逻辑)。

整理好你的源代码，问题就不会出现了。

Answer 2

您可以使用条件逻辑来设置应用程序名称。

if ( YouAreHappy and YouKnowIt ) {
This.name = "ClapYourHands";
}
else {
This.name = "StompYourFeet"; 
}

在现实生活中，您的if条件可能与实际环境和测试环境有所不同。cgi.http_host是一个很好的候选者。
