Answer 1

形式方法必须是 “POST”，您可以使用{{method_field（ 'PUT'）}}设置方法在你app/Exceptions/Handler.php把下面的代码在render功能

//instance of Token Mismatched 
    if ($exception instanceof TokenMismatchException){ 
     //redirect to a form. Here is an example of how I handle mine 
     return redirect($request->fullUrl())->with('csrf_error', $exception->getMessage()); 
    } 

在顶部使用以下行
