laravel 框架，laravel application 容器app

vendor/laravel/framework/src/Illuminate/Foundation/Application.php

Application是laravel的核心容器，幾乎處理所有東西的時候都需要用到，主要功能有：

1. app首先繼承了container，作為一個容器類存在

2。注冊了laravel運行過程的需要的基礎類進容器，并且生成了運行需要的實例。承擔了初始化功能。

?? 這里需要額外說一下，app里面說的所謂注冊，不是指綁定，應該是直接直接實例化了，并注入到容器。但是，針對provider，實例化了provider，并運行了，并不會生成實際的類，而是將類綁定。

3. 額外提供了更方便的一些功能，主要是與程序的環境相關的，比如：provider處理運行是在這里，config app里面的配置就在本類讀取并處理。

具體功能如下：

1. container的功能就不說了，前面微博已經描述這個了。

2. 注冊程序運行中需要的最基礎的類

laravel 框架、?? 在 __construct：構造函數中處理：

?? ???? if ($basePath) {
??????????? $this->setBasePath($basePath);
??????? }
??????? $this->registerBaseBindings();
??????? $this->registerBaseServiceProviders();
??????? $this->registerCoreContainerAliases();

?

　　setBasePath　基本路徑添加進容器實例，這也是這絕大多數框架里面都需要做都事情，防止出現相對絕對等各種路徑使用時候的混亂，總共添加了這么多：

?　　 $this->instance('path', $this->path());
??????? $this->instance('path.base', $this->basePath());
??????? $this->instance('path.lang', $this->langPath());
??????? $this->instance('path.config', $this->configPath());
??????? $this->instance('path.public', $this->publicPath());
??????? $this->instance('path.storage', $this->storagePath());
??????? $this->instance('path.database', $this->databasePath());
??????? $this->instance('path.resources', $this->resourcePath());
??????? $this->instance('path.bootstrap', $this->bootstrapPath());

?

　　registerBaseBindings

??????? 注冊基本綁定，添加app本身進容器實例，然后，PackageManifest添加進容器實例，本功能可以處理一些默認的provider和aliases，本功能后續展開描述。

　　registerBaseServiceProviders

laravel開源項目？　　　　注冊基本的Providers，包括event／log／router 這三部分

　　　　event：vendor/laravel/framework/src/Illuminate/Events/EventServiceProvider.php

　　　　log：vendor/laravel/framework/src/Illuminate/Log/LogServiceProvider.php

　　　　router：vendor/laravel/framework/src/Illuminate/Routing/RoutingServiceProvider.php

??????????????????? router的provider跟別的不一樣，提供了多個相關綁定：router url redirect Psr\Http\Message\ServerRequestInterface Psr\Http\Message\ResponseInterface Illuminate\Contracts\Routing\ResponseFactory Illuminate\Routing\Contracts\ControllerDispatcher

　　registerCoreContainerAliases 注冊一些核心的別名，包括：

?? ??? ??? ??? ??? ???? 'app'????????????????? => [\Illuminate\Foundation\Application::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.password.broker' => [\Illuminate\Auth\Passwords\PasswordBroker::class, \Illuminate\Contracts\Auth\PasswordBroker::class],

?? ??? ??? ???????????? 'view'???????????????? => [\Illuminate\View\Factory::class, \Illuminate\Contracts\View\Factory::class],

所以，初始化之后的app里面的內容如下：

bindings 里面有如下內容：

php框架laravel、events

log
router
url
redirect
Psr\Http\Message\ServerRequestInterface
Psr\Http\Message\ResponseInterface
Illuminate\Contracts\Routing\ResponseFactory
Illuminate\Routing\Contracts\ControllerDispatcher

?

總結一下，application初始化的時候，就干了這么幾個事情：

1. 定位自己，確定文件運行的相關目錄

2. 把自己扔進容器，把用來引用其他代碼的package類實例化進容器。

laravel api？3. log／event／router 三大基本功能提高provider

4. 綁定別名，當然，許多別名，這這個時候，實際上是無效的。因為根本沒綁定到實際類，估計是為了占空。

?

在container之外擴展的功能：

1.? 啟動時額外提供的初始化功能，并且添加了相關事件的注冊，主要函數bootstrapWith。

　　添加事件 bootstrapping bootstrapped 并且注冊外面類提供的所有初始化功能。準備程序運行的參數和環境的注入。

2. registerConfiguredProviders 函數，讀取app.providers里面定義的provider，并注冊。

laravel容器，3. provider的處理，主要函數，register（注冊provider），boot等。

4. 延遲加載deferredServices，延遲加載的provider，只是注冊進container，但是，并不實例化provider，只有調用相關類的時候，才會運行provider進行注冊。

5.handle 直接調用kernel處理request，也是針對網絡訪問的一個出口函數。

?

app在container之外，添加了provider的概念，添加了request相關處理的概念，將container包裝成了一個處理網絡請求的新container。
