laravel容器初始化registerBaseServiceProviders方法
-
上篇讲解了laravel容器的基本使用和原理，这篇继续Application构造方法中的registerBaseServiceProviders方法
在app调用过registerBaseBindings方法后，打印app实例，发现bindings中存放的确实是闭包，shared为true表示单例绑定，instances中表示容器中可以直接复用的实例 Illuminate\Foundation\Application {#2 ▼ #basePath: "/home/vagrant/code/test1" #hasBeenBootstrapped: false #booted: false #bootingCallbacks: [] #bootedCallbacks: [] #terminatingCallbacks: [] #serviceProviders: [] #loadedProviders: [] #deferredServices: [] #appPath: null #databasePath: null #storagePath: null #environmentPath: null #environmentFile: ".env" #isRunningInConsole: null #namespace: null #resolved: [] #bindings: array:1 [▼ "Illuminate\Foundation\Mix" => array:2 [▼ "concrete" => Closure($container, $parameters = []) {#4 ?} "shared" => true ] ] #methodBindings: [] #instances: array:12 [▼ "path" => "/home/vagrant/code/test1/app" "path.base" => "/home/vagrant/code/test1" "path.lang" => "/home/vagrant/code/test1/resources/lang" "path.config" => "/home/vagrant/code/test1/config" "path.public" => "/home/vagrant/code/test1/public" "path.storage" => "/home/vagrant/code/test1/storage" "path.database" => "/home/vagrant/code/test1/database" "path.resources" => "/home/vagrant/code/test1/resources" "path.bootstrap" => "/home/vagrant/code/test1/bootstrap" "app" => Illuminate\Foundation\Application {#2} "Illuminate\Container\Container" => Illuminate\Foundation\Application {#2} "Illuminate\Foundation\PackageManifest" => Illuminate\Foundation\PackageManifest {#5 ?} ] #aliases: [] #abstractAliases: [] #extenders: [] #tags: [] #buildStack: [] #with: [] +contextual: [] #reboundCallbacks: [] #globalResolvingCallbacks: [] #globalAfterResolvingCallbacks: [] #resolvingCallbacks: [] #afterResolvingCallbacks: [] } 下面继续基础服务注册 /** * Register all of the base service providers. * * @return void */ protected function registerBaseServiceProviders() { // 跳转到register方法 $this->register(new EventServiceProvider($this)); $this->register(new LogServiceProvider($this)); $this->register(new RoutingServiceProvider($this)); } /** * Register a service provider with the application. * * @param \Illuminate\Support\ServiceProvider|string $provider * @param bool $force * @return \Illuminate\Support\ServiceProvider */ public function register($provider, $force = false) { // 跳转到getProvider if (($registered = $this->getProvider($provider)) && !$force) { // $this->registerBaseServiceProvider没进来 return $registered; } // If the given "provider" is a string, we will resolve it, passing in the // application instance automatically for the developer. This is simply // a more convenient way of specifying your service provider classes. // 可以看到register方法 是官方更加推荐的注册服务提供者的方式 if (is_string($provider)) { // 跳转到resolveProvider方法 // new一个provider // 我们可以传递一个字符串 laravel会自动帮我们解析 // 框架启动后 可以在任何能够拿到app实例地方调用register方法 会执行自定义服务提供者中的register方法 大家可以自行尝试 $provider = $this->resolveProvider($provider); } $provider->register(); // If there are bindings / singletons set as properties on the provider we // will spin through them and register them with the application, which // serves as a convenience layer while registering a lot of bindings. // laravel为我们提供了方便的进行绑定的方式 那就是将绑定映射写在对应服务提供者中的对应属性中 // 官方建议没有特殊要求的情况下 写在AppServiceProvider中即可 if (property_exists($provider, ‘bindings‘)) { foreach ($provider->bindings as $key => $value) { $this->bind($key, $value); } } if (property_exists($provider, ‘singletons‘)) { foreach ($provider->singletons as $key => $value) { $this->singleton($key, $value); } } // 将已经注册的服务保存到app实例中的对应属性中 serviceProviders loadedProviders // 标识该服务已经注册 $this->markAsRegistered($provider); // If the application has already booted, we will call this boot method on // the provider class so it has an opportunity to do its boot logic and // will be ready for any usage by this developer‘s application logic. // 如果app已经引导完毕 那么在此刻意调用provider的boot方法 if ($this->isBooted()) { $this->bootProvider($provider); } return $provider; // 建议每进行一步都打印下app实例 看到容器中属性的变化即可 } app构造方法中的最后一个registerCoreContainerAliases方法 /** * 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], ‘auth.driver‘ => [\Illuminate\Contracts\Auth\Guard::class], ‘blade.compiler‘ => [\Illuminate\View\Compilers\BladeCompiler::class], ‘cache‘ => [\Illuminate\Cache\CacheManager::class, \Illuminate\Contracts\Cache\Factory::class], ‘cache.store‘ => [\Illuminate\Cache\Repository::class, \Illuminate\Contracts\Cache\Repository::class, \Psr\SimpleCache\CacheInterface::class], ‘cache.psr6‘ => [\Symfony\Component\Cache\Adapter\Psr16Adapter::class, \Symfony\Component\Cache\Adapter\AdapterInterface::class, \Psr\Cache\CacheItemPoolInterface::class], ‘config‘ => [\Illuminate\Config\Repository::class, \Illuminate\Contracts\Config\Repository::class], ‘cookie‘ => [\Illuminate\Cookie\CookieJar::class, \Illuminate\Contracts\Cookie\Factory::class, \Illuminate\Contracts\Cookie\QueueingFactory::class], ‘encrypter‘ => [\Illuminate\Encryption\Encrypter::class, \Illuminate\Contracts\Encryption\Encrypter::class], ‘db‘ => [\Illuminate\Database\DatabaseManager::class, \Illuminate\Database\ConnectionResolverInterface::class], ‘db.connection‘ => [\Illuminate\Database\Connection::class, \Illuminate\Database\ConnectionInterface::class], ‘events‘ => [\Illuminate\Events\Dispatcher::class, \Illuminate\Contracts\Events\Dispatcher::class], ‘files‘ => [\Illuminate\Filesystem\Filesystem::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], ‘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], ‘auth.password.broker‘ => [\Illuminate\Auth\Passwords\PasswordBroker::class, \Illuminate\Contracts\Auth\PasswordBroker::class], ‘queue‘ => [\Illuminate\Queue\QueueManager::class, \Illuminate\Contracts\Queue\Factory::class, \Illuminate\Contracts\Queue\Monitor::class], ‘queue.connection‘ => [\Illuminate\Contracts\Queue\Queue::class], ‘queue.failer‘ => [\Illuminate\Queue\Failed\FailedJobProviderInterface::class], ‘redirect‘ => [\Illuminate\Routing\Redirector::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], ‘url‘ => [\Illuminate\Routing\UrlGenerator::class, \Illuminate\Contracts\Routing\UrlGenerator::class], ‘validator‘ => [\Illuminate\Validation\Factory::class, \Illuminate\Contracts\Validation\Factory::class], ‘view‘ => [\Illuminate\View\Factory::class, \Illuminate\Contracts\View\Factory::class], ] as $key => $aliases) { foreach ($aliases as $alias) { // 跳转到alias方法 $this->alias($key, $alias); } } } /** * Alias a type to a different name. * * @param string $abstract * @param string $alias * @return void * * @throws \LogicException */ // 注册别名 // 可以在Application类的构造方法最后打印一下我们壮观的app实例 // 至此得到了bootstrap/app.php下的 public function alias($abstract, $alias) { if ($alias === $abstract) { throw new LogicException("[{$abstract}] is aliased to itself."); } $this->aliases[$alias] = $abstract; $this->abstractAliases[$abstract][] = $alias; }
下篇会从bootstrap/app.php讲解了。发现错误劳烦指教，感谢！
