Question

我有一张表格，该表格在成功验证后应显示期望的结果。但是在按下按钮时，浏览器显示该页面由于不活动而过期。请刷新，然后重试。

查看页面

<form class="form-horizontal" method="POST" action="{{action('BookController@store')}}">
                <div class="row" style="padding-left: 1%;">
                        <div class="col-md-4">
                            <div class="form-group">
                                <label>Book Name</label><span class="required">*</span>
                                <input type="text" maxlength="100" minlength="3" required="required" runat="server" id="txtBookName" class="form-control" autocomplete="off" autofocus="autofocus" />
                            </div>                            
                            <div class="form-group">
                                    <button type="submit" class="btn btn-primary">Submit</button>        
                            </div>            
                        </div>
                </div>
        </form>

路线代码

//web.php
Route::resource('book','BookController');

控制器代码

class BookController extends Controller
{   

    public function index()
    {
        //
    }


    public function create()
    {
        return view('pages.book');
    }
    public function store(Request $request)
    {
        $validatedInput = $request -> validate([
            'txtBookName' => 'required|string|min:3|max:100'
        ]);

        return $validatedInput;
    }
}

表格网址 http://127.0.0.1:8000/book/create

在按下提交按钮时，页面被重定向到 http://127.0.0.1:8000/book并显示The page has expired due to inactivity. Please refresh and try again.

Answer 1

您可以通过以下方式在表单中发布CSRF令牌：

{{ csrf_field() }}

或者在app / Http / Middleware / VerifyCsrfToken.php中排除您的路线：

protected $except = [
    'your/route'
];

Answer 2

像这样实施以避免过期消息。

<form  action="{{ action('ContactController@store') }}" method="POST">                    
    @csrf <!-- this is the magic line, works on laravel 8 -->
    <!--input components-->
    <!--input components-->
    <!--input components-->
</form>

Answer 3

您应在表单中使用{{csrf_field（）}}。

Answer 4

请在表单类之后执行此操作，因为资源使用@method（'PUT'）

<form class="form-horizontal" method="POST" action="{{action('BookController@store')}}">
   {{csrf_field()}}
   @method('PUT')

                    <div class="row" style="padding-left: 1%;">
                            <div class="col-md-4">
                                <div class="form-group">
                                    <label>Book Name</label><span class="required">*</span>
                                    <input type="text" maxlength="100" minlength="3" required="required" runat="server" id="txtBookName" class="form-control" autocomplete="off" autofocus="autofocus" />
                                </div>                            
                                <div class="form-group">
                                    <button type="submit" class="btn btn-primary">Submit</button>        
                            </div>            
                        </div>
                </div>
        </form>
