Laravel Illuminate\Support\Facades\Input
提问by user2722667
I am new to Laravel and checking out some sample code.
我是 Laravel 的新手，正在查看一些示例代码。
In a controller I see this:
在控制器中，我看到了这个：
<?php
use Illuminate\Support\Facades\Input;
class RegistrationController extends \BaseController {
public function __construct()
{
$this->beforeFilter('guest');
}
Why do I have to use the "use Illuminate\Support\Facades\Input;" ?
为什么我必须使用“ use Illuminate\Support\Facades\Input;”？
Cant I just use eg Input::get(); like I do in my route file?
我不能只使用例如 Input::get(); 就像我在路由文件中所做的那样？

You don't have to use importing namespaces (you don't need to add use Illuminate\Support\Facades\Input;) here.
您不必use Illuminate\Support\Facades\Input;在此处使用导入命名空间（您不需要添加）。
You can accesss Input facade, using Input::get('something')as long as your controller is in global namespace. Otherwise you need to use \Input::get('something')or add use Inputafter <?php.
Input::get('something')只要您的控制器在全局命名空间中，您就可以访问 Input 外观。否则，你需要使用\Input::get('something')或添加use Input之后<?php。

<?php
use Illuminate\Support\Facades\Input;
class RegistrationController extends \BaseController {
public function __construct()
{
$this->beforeFilter('guest');
}
this controller is in global namespace. so you don't need to use use Illuminate\Support\Facades\Input;you can directly call Input::get('foo');
此控制器位于全局命名空间中。所以你不需要使用use Illuminate\Support\Facades\Input;你可以直接调用Input::get('foo');
<?php namespace Foo; //<---- check the namespace
use Input;
class RegistrationController extends \BaseController {
public function __construct()
{
$this->beforeFilter('guest');
}
here you can write either, use Inputor \Input::get('foo')while calling.
在这里你可以一次，use Input或\Input::get('foo')同时呼吁。
