在我的routes.php档案中,我有:

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.我也在表格中输入表格输入值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
