Laravel There are some very useful methods that allow us to customize when commands are executed.不幸的是,Sometimes we need more control,而 Laravel And it doesn't work out of the box.

例如,When you need to execute orders every working day,That means every working day,但不包括假期.You don't want your colleagues（或您自己）Receive daily emails on Christmas morning.

在本文中,我将向您展示如何做到这一点.

避开周末

Laravel 默认自带 helper 方法weekdays来配置 schedule Orders are only executed on weekdays.Suppose we have a command with a signaturesend:daily-email,And we want this order only on weekdays（周一到周五）发送,We can do this by adding it to oursschedulemethod in the console kernel to do this easily：

// app/Console/Kernel.php

class Kernel extends ConsoleKernel
{
    //...
    
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('send:daily-email')->weekdays();
    }
    
    //...
}

就是这样,我们只需要调用weekdaysmethod on the command,Laravel It will only be executed automatically on weekdays.

Now we have a working day.We need to figure out how to make sure Laravel skip vacation.

skip vacation

为此,我们将在 schedule 命令中使用 skip 方法.This method executes the function passed as an argument,如果该函数返回 true,then skip this execution.This way we can check if the day is a holiday.

Now we need to figure out if today is a holiday.有很多方法可以做到这一点,But there is a library you can pass to Carbon 添加一个 mixin 来帮助我们解决这个问题.您可以在此处阅读更多相关信息：https ://github.com/kylekatarnls/business-day

使用 composer 安装库：

composer require cmixin/business-day

安装后,We need to enable in the service provider mixin.AppServiceProvider 是一个很好的地方.

// app/Providers/AppServiceProvider.php


use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Carbon;
use Cmixin\BusinessDay;

class AppServiceProvider extends ServiceProvider
{
    // ... 
    
    public function boot()
    {
        BusinessDay::enable(Carbon::class);
    }
}

在bootin the service provider's method,We call the classenable方法BusinessDay,It's part of the library we just installed.We also need to pass the class where we will add the extra method.Illuminate\Support\Carbon.

Now we need to tell the library which region holiday we are using.You can find all supported regions here：https ://github.com/kylekatarnls/business-day/tree/master/src/Cmixin/Holidays

例如,I'm going to take advantage of American holidays.This means the file I'm looking for is us-national.php,We'll use this filename to configure our vacation.

public function boot()
{
    BusinessDay::enable(Carbon::class);
    Carbon::setHolidaysRegion('us-national');
}

就是这样,现在我们可以通过调用isHolidaycarbon method on the instance to know if a day is a holiday,例如：

now()->isHoliday();

把它们放在一起

We can now complete our command configuration by adding a holiday check to our skip method：

protected function schedule(Schedule $schedule)
{
    $schedule->command('send:daily-email')->weekdays()->skip(function () {
        return now()->isHoliday();
    });
}
