$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);
Inti Instalasi
Apabila aplikasi dijalankan, banyak asas telah dimulakan operasi, jadi pembina berikut akan terus menggunakan suntikan kebergantungan bekas perkhidmatan untuk menyelesaikan kebergantungan antara kelas.
// \Illuminate\Contracts\Http\Kernel 类构造器依赖 \Illuminate\Contracts\Foundation\Application 和 \Illuminate\Routing\Router，将会通过服务容器来处理依赖关系
public function __construct(Application $app, Router $router)
{
$this->app = $app;
// 主要委托 $router 来处理
$this->router = $router;
// 以下均为中间件的设置
$router->middlewarePriority = $this->middlewarePriority;
foreach ($this->middlewareGroups as $key => $middleware) {
$router->middlewareGroup($key, $middleware);
}
foreach ($this->routeMiddleware as $key => $middleware) {
$router->aliasMiddleware($key, $middleware);
}
}
\Illuminate\Contracts\Foundation\Application 的处理：
make 时通过别名方式直接调用 $this->instances['app']
\Illuminate\Routing\Router 的处理:
make 时通过别名方式直接调用 $this->bindings['router'] 数组里面 concrete 对应的匿名函数
Router 依赖 \Illuminate\Contracts\Events\Dispatcher 和 \Illuminate\Container\Container
public function __construct(Dispatcher $events, Container $container = null)
{
$this->events = $events;
$this->routes = new RouteCollection;
$this->container = $container ?: new Container;
}
\Illuminate\Contracts\Events\Dispatcher 的处理：
make 时通过别名方式直接调用 $this->bindings['events'] 数组里面 concrete 对应的匿名函数
Dispatcher 依赖 \Illuminate\Contracts\Container\Container
public function __construct(ContainerContract $container = null)
{
$this->container = $container ?: new Container;
}
\Illuminate\Container\Container 的处理:
make 时直接调用 $this->instances['Illuminate\Container\Container'] = Object(app)
\Illuminate\Contracts\Container\Container 的处理:
make 时调用别名直接调用 $this->instances['app'] = Object(app)
上面两个一样，没有区别
Nota: Kebergantungan yang disenaraikan di atas semuanya diamanahkan terus kepada bekas perkhidmatan untuk pemprosesan automatik Tidak perlu risau tentang $this- >bindings['router'] dan $ pemprosesan acara mengikat ini->bindings['events'], fungsi tanpa nama yang sepadan dengan konkrit kunci tatasusunan akan dipanggil terus semasa membuat.
Coretan kod yang digunakan dalam makeMengembalikan objek Penghala dan menetapkan semula $this->instances['router'] = $objek penghala untuk kali seterusnya Panggil terus.

Mengembalikan objek Penghantar dan menetapkan semula $this->instances['events'] = $objek penghantar untuk panggilan terus seterusnya.
$this->bindings['events'] = [

});
}

$dispatcher = (new \Illuminate\Events\Dispatcher($app))->setQueueResolver(function () use ($app) {
return $app->make(QueueFactoryContract::class);
});
Illuminate\Events\Dispatcher:
public function __construct(ContainerContract $container = null)
{
$this->container = $container ?: new Container;
}
public function setQueueResolver(callable $resolver)
{
$this->queueResolver = $resolver;
return $this;
}Nota: Objek kernel ialah objek yang menggabungkan aplikasi dan penghalaan, dan penghalaan menyuntik objek IlluminateEventsDispatcher, yang merupakan objek teras.
