javascript-使用Laravel错误422 Ajax发布

我正在尝试使用Laravel 5发表一个简单的Ajax帖子.我读到Csrf令牌匹配存在问题,我可以将我的uri放入VerifyCsrftoken期望中以解决此问题.这部分起作用,但是现在我发帖时出现422错误.

我在代码中弄乱了吗？我该如何工作？这是我所拥有的：

HTML：

<div class = "q-form">
                    {!!Form::open(array('url' => 'questions')) !!}
                        <div class = "form-group">
                            {!! Form::hidden('user_id', $myid, ['class' => 'form-control']) !!}
                            {!!Form::label('title', 'Title:')!!}
                            {!!Form::text('title', null, ['class'=> 'form-control'])!!}

                            {!!Form::label('question', 'Question:')!!}
                            {!!Form::textarea('question', null, ['class'=> 'form-control area', 'placeholder' => 'What would you like to ask?'])!!}


                        {!!Form::submit('Ask!', ['class'=> 'btn btn-danger form-control ask'])!!}
                        </div>
                    {!! Form::close() !!}
                </div>

JS：

$('.ask').click(function(e) {

       e.preventDefault();

       var postData = $(this).serializeArray();

       var base_url = 'http://rem-edu-es.eu1.frbit.net/';
       $.ajax({
           type: "POST",
           url: base_url + "questions",
           data: postData,
           success: function (data) {
               console.log(data);
           }

       });
   });

控制器：

 public function book()
{

    if(Request::ajax()){

        return Response::json(Input::all());

    }
}

VerifyCsrftoken：

  class VerifyCsrftoken extends BaseVerifier
{

    protected $except = [
        'book/*',
        'book',
         'questions'

    ];
}

解决方法:

处理响应内的对象时出错.

error :function( data ) {
        if( data.status === 422 ) {
            var errors = $.parseJSON(data.responseText);
            $.each(errors, function (key, value) {
                // console.log(key+ " " +value);
            $('#response').addClass("alert alert-danger");

                if($.isPlainObject(value)) {
                    $.each(value, function (key, value) {                       
                        console.log(key+ " " +value);
                    $('#response').show().append(value+"<br/>");

                    });
                }else{
                $('#response').show().append(value+"<br/>"); //this is my div with messages
                }
            });
          }
