場景

• 像文件描述的那樣，defer service provider 不是沒有每個請求都要載入的，所以可以提高應用的響應效率。defer service provider只會在需要的時候才會載入。 那麼應該怎麼操作

參考文件

解決

• YourServiceProvider需要設定 $defer 屬性 && provides 方法
  • protected $defer = true;
  • The provides method should return the service container bindings registered by the provider
    翻譯一下就是providers 需要返回service container

  /**
     * Get the services provided by the provider.
     *
     * @return array
     */
   public function provides()
    {
        return [Connection::class];
    }

舉例

<?php

namespace App\Providers;

use App\Billing\Stripe;
use Illuminate\Support\ServiceProvider
 
;

class BillServiceProvider extends ServiceProvider
{
    /**
     * Indicates if loading of the provider is deferred.
     *
     * @var bool
     */
    protected $defer = true;

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
    }
 


    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton('billing', function($app){
           return new Stripe();
        });
    }

    /**
     * Get the services provided by the provider.
     *
     * @return array
     */
    public function provides()
    {
        return ['billing'];
    }
}
