环境

简介

Artisan 是 Laravel 的命令行接口的名称，它提供了许多实用的命令来帮助你开发 Laravel 应用，它由强大的 Symfony Console 组件所驱动。

文档

Laravel Artisan

目的

本文目的旨在实现三个简单的命令，分别是优化项目、清除缓存和发送邮件

实现步骤

新建命令

php artisan make:console LaravelOptimize --command=laravel:optimize
php artisan make:console LaravelClean --command=laravel:clean
php artisan make:console SendEmails --command=emails:send

注册命令

打开文件 app/Console/Kernel.php，修改代码如下：

protected $commands = [
    \App\Console\Commands\Inspire::class,
    \App\Console\Commands\SendEmails::class,
    \App\Console\Commands\LaravelClean::class,
    \App\Console\Commands\LaravelOptimize::class,
];

编写命令执行代码

文件 SendEmails.php 代码如下：

line("即将执行邮件发送命令");

        if($this->confirm('确定执行?')){
            $users = UserRepository::all();

            $bar = $this->output->createProgressBar(count($users));

            foreach ($users as $user) {
                $icon = "http://o93kt6djh.bkt.clouddn.com/Laravel-SendEmaillaravel-200x50.png";
                $image = "http://o93kt6djh.bkt.clouddn.com/Laravel-SendEmaillaravel-600x300.jpg";

                Mail::send('emails.test-image',
                    [
                        'name'  => $user->name,
                        'icon'  => $icon,
                        'image' => $image,
                    ],
                    function ($email) use ($user) {
                        $email->to($user->email)->subject('图文邮件标题');
                    });

                $bar->advance();
            }

            $bar->finish();

            $this->info("发送邮件完毕");
        } else {
            $this->info("取消执行邮件发送命令");
        }
    }
}

文件 LaravelOptimize.php 代码如下：

line("即将执行优化缓存命令");
        if($this->confirm('确定执行?')){
            $this->line("开始执行缓存命令");

            Artisan::call("config:cache");
            $this->info('Configuration cache cleared!');
            $this->info('Configuration cached successfully!');

            Artisan::call("route:cache");
            $this->info('Route cache cleared!');
            $this->info('Routes cached successfully!');

            Artisan::call("optimize");
            $this->info('Generating optimized class loader');

            if(function_exists('exec')){
                exec("composer dump-autoload");
            }

            Artisan::call("ide-helper:generate");
            $this->info('A new helper file was written to _ide_helper.php');

            $this->info("优化缓存成功");
        } else {
            $this->info("取消执行优化缓存命令");
        }
    }
}

文件 LaravelClean.php 代码如下：

line("即将执行清除缓存命令");
        if($this->confirm('确定执行?')){
            $this->line("开始执行缓存命令");

            Artisan::call("clear-compiled");

            Artisan::call("auth:clear-resets");
            $this->info('Expired reset tokens cleared!');

            Artisan::call("cache:clear");
            $this->info('Application cache cleared!');

            Artisan::call("config:clear");
            $this->info('Configuration cache cleared!');

            Artisan::call("debugbar:clear");
            $this->info('Debugbar Storage cleared!');

            Artisan::call("route:clear");
            $this->info('Route cache cleared!');

            Artisan::call("view:clear");
            $this->info('Compiled views cleared!');

            $this->info("清除缓存成功");
        } else {
            $this->info("取消执行清除缓存命令");
        }
    }
}

执行效果

在终端分别执行以下代码：

php artisan laravel:optimize
php artisan laravel:clean
php artisan emails:send

执行效果分别如下显示：

php artisan laravel:optimize

执行缓存清楚

php artisan laravel:clean
