我的看法：<form action="/AddJuiceForm" method="POST">    @csrf;    <div class="form-group">        <label for="FruitName">Fruit Name : </label>        <input type="text"            class="form-control"            placeholder="Enter the Fruit Name"            name="fruitname">    </div>    <div class="form-group">        <label for="JuiceName">Juice Name : </label>        <input type="text"            class="form-control"            placeholder="Enter the Juice Name"            name="juicename">    </div>    <button type="submit" class="btn btn-primary">Submit</button></form>我的路線/web.php：Route::post('AddJuiceForm','JuiceController@insertjuice ');我的控制器：<?phpnamespace App\Http\Controllers;use App\JuiceModel;use Illuminate\Http\Request;class JuiceController extends Controller{    public function insertjuice()    {        dd(request()->all);    }}結果：我得到“空”作為輸出幫助我哪里出錯了？
