bootstrap/app.php文件分析
Illuminate\Foundation\Application文件分析

前言

上一篇文章，研究了larvael框架入口文件 index.php，这一篇深入研究获取框架实例底层代码
至于 composer自动加载源码分析请到这观看

bootstrap/app.php文件分析

 $app = new Illuminate\Foundation\Application(
    realpath(__DIR__.'/../')
);

$app->singleton(
    Illuminate\Contracts\Http\Kernel::class,
    App\Http\Kernel::class
);

$app->singleton(
    Illuminate\Contracts\Console\Kernel::class,
    App\Console\Kernel::class
);

$app->singleton(
    Illuminate\Contracts\Debug\ExceptionHandler::class,
    App\Exceptions\Handler::class
);

return $app;

第一步获取应用实例
第二步绑定框架核心 http内核，控制台内核，异常处理单例

Illuminate\Foundation\Application文件分析

1. 引入

use Closure;   //PHP 匿名函数类
use RuntimeException; //php 运行异常类
use Illuminate\Support\Arr; //框架支持的arr类
use Illuminate\Support\Str;//框架支持的str类
use Illuminate\Http\Request;//框架http 请求类
use Illuminate\Support\Collection;//框架支持的集合类
use Illuminate\Container\Container;//框架容器核心类
use Illuminate\Filesystem\Filesystem;//框架文件系统的文件类
use Illuminate\Log\LogServiceProvider;//框架日志组件日志服务提供者
use Illuminate\Support\ServiceProvider;//框架支持的服务提供者
use Illuminate\Events\EventServiceProvider;//框架事件系统的事件服务提供者
use Illuminate\Routing\RoutingServiceProvider;//框架路由组件的路由服务提供者
use Symfony\Component\HttpKernel\HttpKernelInterface;//Symfony框架http内核接口
use Symfony\Component\HttpKernel\Exception\HttpException;//Symfony框架http内核异常下http异常类
use Illuminate\Contracts\Http\Kernel as HttpKernelContract;//框架http内核契约
use Illuminate\Foundation\Bootstrap\LoadEnvironmentVariables;//框架基础加载环境变量类
use Symfony\Component\HttpFoundation\Request as SymfonyRequest;//Symfony框架http请求类
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;//Symfony框架http内核异常类
use Illuminate\Contracts\Foundation\Application as ApplicationContract;//框架契约基础类

2. 定义类定义属性

class Application extends Container implements ApplicationContract, HttpKernelInterface
{//定义Application对象继承Container，实现ApplicationContract, HttpKernelInterface
    const VERSION = '5.7.12'; //版本号
    protected $basePath;//基本路径
    protected $hasBeenBootstrapped = false;//应用程序是否已被自举。
    protected $booted = false;//引用程序是否已启动
    protected $bootingCallbacks = [];//引导回调的数组
    protected $bootedCallbacks = [];//启动回调的数组
    protected $terminatingCallbacks = [];//终止回调的数组
    protected $serviceProviders = [];//注册的服务提供者
    protected $loadedProviders = [];//加载的服务提供者的名称
    protected $deferredServices = [];//延迟的服务提供者的名称
    protected $databasePath;//数据库路径
    protected $storagePath;//存储路径
    protected $environmentPath;//环境变量路径
    protected $environmentFile = '.env';//环境变量文件
    protected $namespace;//应用程序名称空间

3. 构造函数，初始化处理

1、setBasePath // 设置应用基础路径
2、registerBaseBindings // 绑定容器中的所有应用程序路径
3、registerBaseServiceProviders // 注册基本绑定
4、registerCoreContainerAliases //注册容器核心类别名

public function __construct($basePath = null)
    {
        if ($basePath) {
            $this->setBasePath($basePath);
        }
        $this->registerBaseBindings();
        $this->registerBaseServiceProviders();
        $this->registerCoreContainerAliases();
    }

4. 设置基础路径

1、bindPathsInContainer

    public function setBasePath($basePath)
    {
        $this->basePath = rtrim($basePath, '\/');
        $this->bindPathsInContainer();
        return $this;
    }

5. 绑定容器中的所有应用程序路径

protected function bindPathsInContainer()
    {
        $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());
}

6. 将基本绑定注册到容器中

1、static::setInstance
2、instance

       protected function registerBaseBindings()
     {
        static::setInstance($this);//设置全局容器可用实例
        $this->instance('app', $this);//绑定当前实例到app
        $this->instance(Container::class, $this);//绑定当前实例到Container
        $this->instance(PackageManifest::class, new PackageManifest(
            new Filesystem, $this->basePath(), $this->getCachedPackagesPath()
        ));//文件实例绑定到PackageManifest
    }

7. 注册所有的基础服务提供者

1、register

protected function registerBaseServiceProviders()
    {
        $this->register(new EventServiceProvider($this));//1. 事件服务提供者        
        $this->register(new LogServiceProvider($this));// 2. 日志服务提供者
        $this->register(new RoutingServiceProvider($this));  //3. 路由服务提供者
    }

8. 注册方法剖析

1、getProvider
2、resolveProvider
3、bind
4、singleton
5、markAsRegistered
6、bootProvider
7、参考链接

   public function register($provider, $force = false)
    {
        //判断该服务提供者是否已注册，已经注册直接返回实例
        if (($registered = $this->getProvider($provider)) && ! $force) {
            return $registered;
        }
        //如果传入一个字符串（类名）
        if (is_string($provider)) {
            //直接去实例化(直白点就是new 这个类)
            $provider = $this->resolveProvider($provider);
        }
        //如果该服务提供者存在register方法，直接执行
        if (method_exists($provider, 'register')) {
            $provider->register();
        }
       //如果服务提供者包含bindings属性，则进行
        if (property_exists($provider, 'bindings')) {
            foreach ($provider->bindings as $key => $value) {
                $this->bind($key, $value);
            }
        }
        //如果服务提供者包含singletons属性，则进行
        if (property_exists($provider, 'singletons')) {
            foreach ($provider->singletons as $key => $value) {
                $this->singleton($key, $value);
            }
        }
        //标记该程序为已注册，加入已注册服务提供者数组和已加载服务提供者数组
        $this->markAsRegistered($provider);
        //如果程序已启动，调用服务提供者boot方法
        if ($this->booted) {
            $this->bootProvider($provider);
        }

            foreach ($aliases as $alias) {
                $this->alias($key, $alias);
            }
        }
    }

73. 清除所有绑定和解决实例的容器

1、parent::flush

    public function flush()
    {
        parent::flush();
        $this->buildStack = [];
        $this->loadedProviders = [];
        $this->bootedCallbacks = [];
        $this->bootingCallbacks = [];
        $this->deferredServices = [];
        $this->reboundCallbacks = [];
        $this->serviceProviders = [];
        $this->resolvingCallbacks = [];
        $this->afterResolvingCallbacks = [];
        $this->globalResolvingCallbacks = [];
    }

74. 获取命名空间

    public function getNamespace()
    {
        if (! is_null($this->namespace)) {
            return $this->namespace;
        }
        $composer = json_decode(file_get_contents(base_path('composer.json')), true);
        foreach ((array) data_get($composer, 'autoload.psr-4') as $namespace => $path) {
            foreach ((array) $path as $pathChoice) {
                if (realpath(app_path()) == realpath(base_path().'/'.$pathChoice)) {
                    return $this->namespace = $namespace;
                }
            }
        }
        throw new RuntimeException('Unable to detect application namespace.');
    }

75. 运行给定的引导类数组

public function bootstrapWith(array $bootstrappers)
    {
        $this->hasBeenBootstrapped = true;

        foreach ($bootstrappers as $bootstrapper) {
            $this['events']->dispatch('bootstrapping: '.$bootstrapper, [$this]);

            $this->make($bootstrapper)->bootstrap($this);

            $this['events']->dispatch('bootstrapped: '.$bootstrapper, [$this]);
        }
    }
