如何将句柄方法调用到routes.php文件中?

Question

当我在命令行中运行php artisan make:greetings命令时，我想打印一个日志消息，它应该在我的日志文件中返回一条消息，对于如何在routes.php文件中调用句程方法，因此我正在编写一些代码，但我得到以下错误请帮助我解决这个问题

Error

routes.php

Artisan::command('make:greetings',[Hello::class,'handle'=>true]);

Hello.php

<?php
namespace AppConsoleCommands;
use IlluminateConsoleCommand;
use Log;
class Hello extends Command
{
/**

protected $signature = 'make:greetings';
/**

protected $description = 'Command description';
/**

public function __construct()
{
parent::__construct();
}
/**

public function handle()
{

return Log::info("welcome message");
}
}

第二个参数必须是一个闭包，并且你正在传递一个数组，这个闭包用于将数据传递给你的句柄方法，因为你的句柄方法中没有任何参数，请使用call method而不是command，试试这个:

Artisan::call('make:greetings');

，也不要忘记在AppConsoleKernel类中注册你的命令:

protected $commands = [
'AppConsoleCommandsHello',
];
