TokenMismatchException在laravel

Question

我是新來laravel

我想改變發送多形式要求laravel後註釋狀態

{!! Form::open(['method'=>'patch','onchange'=>'submit()','action'=>['CommentController@update',$item->id]]) !!} 
{!! Form::select('show',[0 =>'No',1 =>'Yes' ], $show_view) !!} 
{!! Form::close() !!} 

表明我這個錯誤

Answer 1

你必須將表單中的令牌提交（用於防止CSRF攻擊）。

如果您在Laravel 5，使用

{!! csrf_field() !!} 

如果你正在做一個AJAX請求，你可以在頭在這個部分中添加標記X-CSRF-TOKEN 看：http://laravel.com/docs/5.1/routing#csrf-x-xsrf-token

如果您在Laravel 4，你可以在你的表格中使用Form::token()。

另一個選項是從哪個不建議CSRF保護排除URI，但如果需要的話可以做到： http://laravel.com/docs/5.1/routing#csrf-excluding-uris
