laravel 中关于Request facades的一个问题

Jun 06, 2016 pm 08:24 PM
facades laravel php

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>
Copy after login
Copy after login

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>
Copy after login
Copy after login

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。
