laravel中的一次自定义cron计划 [英] One time custom cron schedule in laravel

问题描述

我想在自定义日期仅运行一次cron&用户在表格中输入的时间.最好的方法是什么?

I want to run a cron just once at a custom date & time entered by the user in a form. What is the best way to do this?

我发现可以像这样在laravel中安排自定义cron

I found that a custom cron can be scheduled in laravel like this

->cron(‘* * * * * *’);             

按照自定义Cron时间表运行任务.

Run the task on a custom Cron schedule.

但是我找不到*表示的时间格式.

But I could not find the time format what the * mean.

或更简单的是，可以通过添加日期和时间来做到这一点.

Or much simpler, can it be done like this by adding the date and time.

->at('28/04/2020 13:00');

这怎么办?

推荐答案

Laravel文档在此处任务计划

Laravel documentation has in detail description on that in here Task Scheduling

您可以将调度逻辑添加到给定文件中

You can add your scheduling logic in a given file

App \ Console \ Kernel

App\Console\Kernel

当前，laravel具有与您的要求完全匹配的功能，但它提供了-> monthlyOn(23，'13:00'); ，通过它您可以满足您的要求，它每月23日的13:00运行任务

Currently, laravel have the kind of functionality that exactly match your requirement but it provide a ->monthlyOn(23, '13:00'); via which you can achieve your requirement, It Run the task every month on the 23th at 13:00

protected function schedule(Schedule $schedule)
    {
        $schedule->call(function () {

        })->->monthlyOn(23, '13:00');
    }

上面的代码每个月23日(服务器时间13:00)运行任务.

The above code runs the task every month on the 23th at 13:00 hours server time.

出于您的目的，您可以按照以下说明更改cron计划

For your purpose you can change cron scheduling as given below

00 13 28 APR Fri *

1st * Minute
2nd * Hour
