你的问题

• 为何需要扩展config？
• 想法初期，更好的更新第三方包和框架！构思了更好的构建应用。
• 扩展的config 组件有什么特性
• 增加addNamespace 方法, 需要 symfony/finder 包支持
• 在项目增加自己的config目录或第三方包
• 需要原框架哪些？
• 新增path/Application.php 然后在bootstrap/app.php 更改创建的类, 操作如下：

复制
class Application extends \Illuminate\Foundation\Application
{
    /**
     * Register the core class aliases in the container.
     *
     * @return void
     */ 
    public function registerCoreContainerAliases()
    {
        foreach ([
            'app' => [self::class, \Illuminate\Contracts\Container\Container::class, \Illuminate\Contracts\Foundation\Application::class, \Psr\Container\ContainerInterface::class],
            'auth' => [\Illuminate\Auth\AuthManager::class, \Illuminate\Contracts\Auth\Factory::class],

            'config' => [\Ofcold\Component\Config\Repository::class, \Illuminate\Contracts\Config\Repository::class],
            'cookie' => [\Illuminate\Cookie\CookieJar::class, \Illuminate\Contracts\Cookie\Factory::class, \Illuminate\Contracts\Cookie\QueueingFactory::class],

            'filesystem' => [\Illuminate\Filesystem\FilesystemManager::class, \Illuminate\Contracts\Filesystem\Factory::class],
            'filesystem.disk' => [\Illuminate\Contracts\Filesystem\Filesystem::class],
            'filesystem.cloud' => [\Illuminate\Contracts\Filesystem\Cloud::class],
            'hash' => [\Illuminate\Hashing\HashManager::class],
            'hash.driver' => [\Illuminate\Contracts\Hashing\Hasher::class],
            'translator' => [\Illuminate\Translation\Translator::class, \Illuminate\Contracts\Translation\Translator::class],
            'log' => [\Illuminate\Log\LogManager::class, \Psr\Log\LoggerInterface::class],
            'mail.manager' => [\Illuminate\Mail\MailManager::class, \Illuminate\Contracts\Mail\Factory::class],
            'mailer' => [\Illuminate\Mail\Mailer::class, \Illuminate\Contracts\Mail\Mailer::class, \Illuminate\Contracts\Mail\MailQueue::class],
            'auth.password' => [\Illuminate\Auth\Passwords\PasswordBrokerManager::class, \Illuminate\Contracts\Auth\PasswordBrokerFactory::class],

            'redis' => [\Illuminate\Redis\RedisManager::class, \Illuminate\Contracts\Redis\Factory::class],
            'redis.connection' => [\Illuminate\Redis\Connections\Connection::class, \Illuminate\Contracts\Redis\Connection::class],
            'request' => [\Illuminate\Http\Request::class, \Symfony\Component\HttpFoundation\Request::class],
            'router' => [\Illuminate\Routing\Router::class, \Illuminate\Contracts\Routing\Registrar::class, \Illuminate\Contracts\Routing\BindingRegistrar::class],
            'session' => [\Illuminate\Session\SessionManager::class],
            'session.store' => [\Illuminate\Session\Store::class, \Illuminate\Contracts\Session\Session::class],

            'view' => [\Illuminate\View\Factory::class, \Illuminate\Contracts\View\Factory::class],
        ] as $key => $aliases) {
            // array_walk($aliases, fn ($alias) => $this->alias($key, $alias));  
            foreach ($aliases as $alias) {
                $this->alias($key, $alias);
            }
        }
    }
}

新增bootstraps/LoadConfiguration.php

复制
<?php
 
namespace Bootstrap;
 
use Exception;
use Illuminate\Contracts\Config\Repository as RepositoryContract;
use Illuminate\Contracts\Foundation\Application;
use Ofcold\Component\Config\Repository;
use SplFileInfo;
use Symfony\Component\Finder\Finder;
 
class LoadConfiguration
{
    /**
     * Bootstrap the given application.
     *
     * @param  \Illuminate\Contracts\Foundation\Application  $app
     *
     * @return void
     */ 
    public function bootstrap(Application $app)
    {
        $items = [];
 
 
        if (is_file($cached = $app->getCachedConfigPath())) {
            $items = require $cached;
 
            $loadedFromCache = true;
        }
 
        $app->instance('config', $config = new Repository($items));
 
        if (! isset($loadedFromCache)) {
            $config->addNamespace($app->configPath());
        }
 
        $app->detectEnvironment(fn () => $config->get('app.env', 'production'));
 
        date_default_timezone_set($config->get('app.timezone', 'Asia/Shanghai'));
 
        mb_internal_encoding('UTF-8');
    }
}
 

在app/Http/Kernel.php 和 app/console/Kernel.php 增加

复制
/**
     * The bootstrap classes for the application.
     *
     * @var string[]
     */ 
    protected $bootstrappers = [
        \Illuminate\Foundation\Bootstrap\LoadEnvironmentVariables::class,
        \Bootstrap\LoadConfiguration::class,
        \Illuminate\Foundation\Bootstrap\HandleExceptions::class,
        \Illuminate\Foundation\Bootstrap\RegisterFacades::class,
        \Illuminate\Foundation\Bootstrap\SetRequestForConsole::class,
        \Illuminate\Foundation\Bootstrap\RegisterProviders::class,
        \Illuminate\Foundation\Bootstrap\BootProviders::class,
    ];

• 还差哪些工作没做？
• 在构建第三方包的时候需要覆盖当前的config 既 path/vendor
• 不影响config 缓存, 在你的ServiceProvider.php

复制
! $this->app->configurationIsCached() && $this->app['config']->addNamespace('path', 'namespace');

安装

复制
composer require ofcold/component-config

使用

复制
$config = new Ofcold\Component\Config\Repository
 
// Set initial configuration items
$config->addNamespace('your-config-path');
 
// Add a namespace to configuration.
$config->addNamespace(__DIR__ '/your-path/config', 'user');
 
// Get a config item.
$config->get('foo');
 
// Get a namespace config item.
$config->get('user::foo.bar');
