Question

我随机地＆＃34;我的beanstalked队列中的一些作业失败了。两个问题：

1 /通过查看数据库中失败的作业表，我如何插入内部记录的内容？数据封闭意味着＆＃34;没有＆＃34;读它的时候。有更多信息可以做些什么吗？

2 /我浏览了Laravel的控制台日志，这是失败的：

[2015-04-29 15:40:51] production.ERROR: exception 'ErrorException' with message 'Trying to get property of non-object' in /home/forge/api.hello.me/vendor/jeremeamia/SuperClosure/src/Jeremeamia/SuperClosure/SerializableClosure.php(99) : eval()'d code:6
Stack trace:...

但是我不知道究竟是什么失败...堆栈跟踪没有帮助，只是从

开始

    [internal function]: Jeremeamia\SuperClosure\SerializableClosure::{closure}(Object(Illuminate\Queue\Jobs\BeanstalkdJob))
#2 /home/forge/api.hello.me/vendor/jeremeamia/SuperClosure/src/Jeremeamia/SuperClosure/SerializableClosure.php(64): ReflectionFunction->invokeArgs(Array)

稍后在

完成几行

#15 /home/forge/api.hello.me/vendor/symfony/console/Symfony/Component/Console/Application.php(124): Symfony\Component\Console\Application->doRun(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))
    #16 /home/forge/api.hello.me/artisan(59): Symfony\Component\Console\Application->run()
    #17 {main} [] []

有关我如何理解/了解发生了什么的任何想法？队列甚至都没有失败......

ps：完整堆栈跟踪：

Laravel排队工作的方式是将您提供的所有数据序列化为payload，并将其粘贴到您的数据库中。当您处理队列时，它会神奇地取消序列化所有这些数据，这样您在内存中的对象基本上与将其弹入队列时的对象相同。当您更改序列化对象的类定义，或者您的对象没有完全序列化正确时（这似乎就是这种情况），问题就出现了......

我建议您尝试不序列化匿名函数，因为Laravel使用SuperClosure来执行此操作，而且非常hacky。

[internal function]: Jeremeamia\SuperClosure\SerializableClosure::{closure}(Object(Illuminate\Queue\Jobs\BeanstalkdJob))

尝试将更简单的对象推送到您的Beanstalk队列中（即不要将对象发送到队列中），您将不会遇到此问题。
