$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.

Objek kernel ialah objek yang menggabungkan aplikasi dan penghalaan, dan penghalaan menyuntik objek IlluminateEventsDispatcher, yang merupakan objek teras.
