我一直在为我的应用程序制作一个excel导出功能。由于行数众多，列数众多，并且超时值为5分钟，因此我将作业的有效负载分为多个具有不同参数的相同作业，然后将新行追加到现有的Excel文件中。
我遇到以下错误：
[2019-07-08 14:13:04] local.ERROR: Test\Jobs\CalculateExport has been attempted too many times or run too long. The job may have previously timed out. {"exception":"[object] (Illuminate\\Queue\\MaxAttemptsExceededException(code: 0): Test\\Jobs\\CalculateExport has been attempted too many times or run too long.

Beanstalkd用作队列处理器。除了以上所述，似乎没有例外。
工作类别如下：

我尝试更改作业本身的作业超时，使用全局调度来更改CalculateExport :: dispatch，将尝试设置为1。我在beastalkd控制台中看到工作被接连分派。但是，只要达到5分钟，它就会结束。我怀疑它以某种方式从未完成过上一个作业-这就是为什么我添加了删除作业。
谢谢！
答案 0 :(得分：0)
在calculateExport函数的开头，还设置了PHP参数max_execution_time。
ini_set（'max_execution_time'，2000）;
现在大概设置为300（秒）= 5分钟
