laravel5.8 自定义命令

#### 1.命令行执行
```php
php artisan make:command MakeTransformer 
```
生成 TransformerMakeCommand.php 文件，当中代码如下：
```php
<?php

namespace App\Console\Commands;

use Illuminate\Console\GeneratorCommand;
use Illuminate\Support\Str;

class MakeTransformer extends GeneratorCommand
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'make:transformer {name}';

/**
     * The console command description.
     *
     * @var string
     */
    protected $description = '创建 transformer';

protected function getStub()
    {
        return __DIR__.'/stubs/transformer';
    }

protected function getPath($name)
    {
        $name = Str::replaceFirst($this->rootNamespace(), '', $name);

return $this->laravel['path'].'/'.str_replace('\\', '/', $name).'Transformer.php';
    }

protected function buildClass($name)
    {
        $stub = $this->files->get($this->getStub());

return $this->replaceClass($this->replaceInstance($stub, $name), $name);
    }

protected function replaceInstance($stub, $name)
    {
        $class = str_replace($this->getNamespace($name).'\\', '', $name);

return str_replace('dummyInstance', lcfirst($class), $stub);
    }

protected function getDefaultNamespace($rootNamespace)
    {
        return $rootNamespace.'\Transformers';
    }
}
```
#### 2.在下面图片所示目录中创建模版文件
目录：app\Console\Commands\Stubs
transformer.stub 中的代码如下：
```php
<?php

namespace App\Transformers;

use App\Models\DummyClass;
use League\Fractal\TransformerAbstract;

class DummyClassTransformer extends TransformerAbstract
{
    public function transform(DummyClass $dummyInstance)
    {
        return [
            'id' => $dummyInstance->id,
        ];
    }
}
```
#### 3.测试命令行
```php

```
