post 方法提交 控制器里面获取不了值

Route::group(
[
'prefix' => LaravelLocalization::setLocale(),
'middleware' => [ 'localeSessionRedirect', 'localizationRedirect' ]
],
function()
{
/** ADD ALL LOCALIZED ROUTES INSIDE THIS GROUP **/
Route::get('/', function()
{
return view('welcome');
});
Route::resource('wel','UsersController');

<form action="/wel" method="post">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="text" id="name" name="name" />
<input type="submit" value="提交">
<button type="submit">提交</button>
</form>
public function index()
{
$name = Input::get('name');
echo $name;
}

什么都不会输出
