我的 Apache 日志中出现“预期的令牌不存在"错误 [英] “Expected token not present” error in my Apache log

问题描述

我的网站在带有 mod_perl 的 Apache 2 上运行，并使用 Mason 模板系统.我没有在我的网站中使用任何身份验证系统或任何会话，但有时(随机)我收到此错误:

My website runs on Apache 2 with mod_perl and uses the Mason template system. I am not using any authentication system or any sessions in my website, but sometimes (at random) I get this error:

服务器遇到内部错误或配置错误无法完成您的请求.

Internal Server Error

请联系服务器管理员，[e-mail]并通知他们错误发生的时间，以及您可能会做的任何事情已经做了可能导致错误的事情.

此外，在运行时遇到 500 Internal Server Error 错误尝试使用 ErrorDocument 来处理请求.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

在错误日志中，对应的记录为:

In the error log, the corresponding record is:

服务器版本字符串:

Apache/2.2.8 (Ubuntu) mod_apreq2-20051231/2.6.0 mod_perl/2.0.3 Perl/v5.8.8 Server

我的浏览器发送了这个奇怪的 cookie:

My browsers sends this weird cookie:

Expires:                When I close my browser

当我删除它时，我可以重新加载我的页面并且它可以工作.然而，点击几下后，问题又出现了.

When I delete it, I can reload my page and it works. However after a couple of clicks the problem reappears.

为什么我的错误日志中出现错误?如何解决?

推荐答案

因为您在解决方案中省略了 return 语句，所以您还必须在 eval 块中圈出继续语句.否则，您可以期待第一次星座，其中在未定义的值上调用函数cookie_class"会引发异常.因此

Because you omit the return statement in your solution, you had to circle the proceeding statement in an eval block as well. Otherwise you can expect a first time constellation where a function "cookie_class" is called on an undefined value what would throw an exception. Therefore

另外更换

$jar->cookie_class(__PACKAGE__);

与

eval {$jar->cookie_class(__PACKAGE__)};

享受吧！
