TokenMismatchException在laravel

Question

我是新来laravel

我想改变发送多形式要求laravel后注释状态

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

表明我这个错误

Answer 1

你必须将表单中的令牌提交（用于防止CSRF攻击）。

如果您在Laravel 5，使用

{!! csrf_field() !!} 

如果你正在做一个AJAX请求，你可以在头在这个部分中添加标记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()。

另一个选项是从哪个不建议CSRF保护排除URI，但如果需要的话可以做到： http://laravel.com/docs/5.1/routing#csrf-excluding-uris
