php - 如何将句柄方法调用到 routes.php 文件中？

问题描述

我想php artisan make:greetings在命令行中运行命令时打印一条日志消息，它应该在我的日志文件中返回一条消息，说明如何在 routes.php 文件中调用句柄方法，因为我正在编写一些代码，但我是收到以下错误请帮助我解决此问题

Error

   TypeError

解决方案

第二个参数必须是一个闭包，并且您正在传递一个数组，此闭包用于将数据传递给您的句柄方法，并且由于您的句柄方法中没有任何参数，请使用调用方法而不是命令，试试这个：

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

并且不要忘记在 App\Console\Kernel 类中注册您的命令：

    protected $commands = [
        'App\Console\Commands\Hello',
    ];
