建立一個服務


<?php
namespace App\Services;
class FooService
{
    public function __construct(){
 
    }
 
    public function  doSomething(){
        echo "some";
    }
}


綁定服務

$this->app->bind('\App\Services\FooService');


在控制器里調用
$fooService = app()->make('\App\Services\FooService');
$fooService->doSomething();
