laravel 中关于Request facades的一个问题
看了一些laravel中facades的一些文档,大致有些了解,但有一点问题想请教大家
app.php的aliasse中
<code>'Request' => 'Illuminate\Support\Facades\Request',</code>
我是这样理解的,相当于运行了vendor/laravel/framework/src/Illuminate/Support/Facades/Request.php,主要语句就是其中的一句
<code>protected static function getFacadeAccessor() { return 'request'; } </code>
要使这个facades起作用,还要绑定到服务提供者,也就是要执行App::bind()
这个函数,但查了一遍代码,没发现哪里出现过。
请问这个facades绑定到服务提供者的代码在哪里,或者说是其它的实现方式。谢谢!

相关代码都在同一个文件夹下的Facade类里面
粗看了一下 应该是resolveFacadeInstance把全局容器中的变量绑定到这里的作为对象缓存的静态成员resolvedInstance中的
__callStatic->getFacadeRoot->resolveFacadeInstance&getFacadeAccessor
是不是在public/index.php中直接使用了?
Illuminate/Foundation/Application.php
Facades 只是提供个快速访问的代理,注册并不在这里。
