laravel 5：找不到类“输入”

In my routes.php我有的文件：

Route::get('/', function () {

    return view('login');
});

Route::get('/index', function(){
    return view('index');
});

Route::get('/register', function(){
    return view('register');
});
Route::post('/register',function(){

    $user = new \App\User;
    $user->username = input::get('username');
    $user->email  = input::get('email');
    $user->password = Hash::make(input::get('username'));
    $user->designation = input::get('designation');
    $user->save();

});

我有一个用户注册表格。我还采用了表单输入值routes.php.

但是当我注册用户时出现错误。 错误：

FatalErrorException in routes.php line 61:
Class 'input' not found

It is Input并不是input. 这次提交 https://github.com/laravel/laravel/commit/2adbbbd91e9d6e2d569cc56f138b7273efe25651已删除Input立面定义来自config/app.php因此你必须手动将其添加到aliases数组如下，

'Input' => Illuminate\Support\Facades\Input::class,

或者您可以导入Input直接按要求立面，

use Illuminate\Support\Facades\Input;
