Here's my attempt at figuring out what actually happens on an Auth::user()call:
这是我试图弄清楚Auth::user()通话中实际发生的事情：
Auth::user()
Illuminate\Support\Facades\Auth
extends Illuminate\Support\Facades\Facade
Facade::__callStatic('user')
static::getFacadeRoot()
resolveFacadeInstance(static::getFacadeAccessor == 'auth' (from Auth class))
return static::$app[$name];
static::$app is instance of Illuminate\Foundation\Application
extends Illuminate\Container\Container
which implements ArrayAccess(which is why $obj[]syntax works)
哪个实现ArrayAccess（这就是$obj[]语法起作用的原因）
Container::offsetGet(auth)
Application::make(auth)
Container::getAlias(auth) return 'auth'
Container::make(auth)
Container::resolve(auth)
yadda, yadda, yadda
See in Application::registerCoreContainerAliases
yadda, yadda, yadda 见 Application::registerCoreContainerAliases
'auth' = Illuminate\Auth\AuthManager
AuthManager::user() = AuthManager::__call = $this->guard()->user()
AuthManager::guard(web)
AuthManager::resolve(web) (see config/auth.php)
AuthManager::createSessionDriver() returns new Illuminate\Auth\SessionGuard
SessionGuard::user() // <---- this is what actually get's called, based on default config
