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?類構(gòu)造器依賴?\Illuminate\Contracts\Foundation\Application?和?\Illuminate\Routing\Router，將會(huì)通過服務(wù)容器來處理依賴關(guān)系
public?function?__construct(Application?$app,?Router?$router)

????}
????foreach?($this->routeMiddleware?as?$key?=>?$middleware)?{

}
\Illuminate\Contracts\Foundation\Application?的處理：
make?時(shí)通過別名方式直接調(diào)用?$this->instances['app']
\Illuminate\Routing\Router?的處理:
make?時(shí)通過別名方式直接調(diào)用?$this->bindings['router']?數(shù)組里面?concrete?對應(yīng)的匿名函數(shù)
Router?依賴?\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?=?$container??:?new?Container;
}
\Illuminate\Contracts\Events\Dispatcher?的處理：
make?時(shí)通過別名方式直接調(diào)用?$this->bindings['events']?數(shù)組里面?concrete?對應(yīng)的匿名函數(shù)
Dispatcher?依賴?\Illuminate\Contracts\Container\Container
public?function?__construct(ContainerContract?$container?=?null)
{
????$this->container?=?$container??:?new?Container;
}
\Illuminate\Container\Container?的處理:
make?時(shí)直接調(diào)用?$this->instances['Illuminate\Container\Container']?=?Object(app)
\Illuminate\Contracts\Container\Container?的處理:
make?時(shí)調(diào)用別名直接調(diào)用?$this->instances['app']?=?Object(app)
上面兩個(gè)一樣，沒有區(qū)別
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.
