我正在嘗試通過按下按鈕通過隱藏字段將數據發布到數據庫但是我面臨的錯誤是419 Page Expired這是我的觀點：-<div><h1> All Posts </h1>@if(count($user) > 0)  @foreach($user as $post)<form action="/f" method="POST"><input type="hidden" id="friends" name="friends" value="{{$post->id}}" /><button type="submit" class="btn btn-primary">                                    {{ __('chat') }}                                </button></form><div class="well"> <a href="/profile/1"<button class="button btn-success">chat</button>></a>  <h3>{{$post->title}}</h3>  <h4>{{$post->body}}</h4>  <small>written on {{$post->created_at}}</small></div>@endforeach@else   <p>No Forms Found</p>@endif</div>這是我的路線：-Route::post('/f', 'FriendsController@store');這是我的控制器：-<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request;class FriendsController extends Controller{    public function store(Request $request){   dd($request->all());    post::create([        'friends' => $request->friends,        ]);     return redirect('/profile/' . auth()->user()->id);}}我可能在我的商店方法中犯了錯誤請檢查并讓我知道它有什么問題我只是一個初學者 - 謝謝
