Laravel's Dependency Injection Container in Depth

Translations: Korean (by Yongwoo Lee)

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

	<?php

	/**
	* Class InviteCode
	* 邀请码生成类
	*
	* ```
	* $inviteCode = new InviteCode('123456789');
	* var_dump($inviteCode->enCode(1)); // string(8) "00000002"
	* var_dump($inviteCode->deCode("00000002")); // int(1)

	<?php

	namespace App\Http\Middleware;

	use Closure;
	use Illuminate\Support\Facades\Vite;
	use Illuminate\Support\Str;

	/**
	* Simple Content Security Policy middleware.
