Laravel表单抛出方法异常错误(check Post everywhere)

<form id="searchForm"  action="searchProduct" method="post">
            <input type="hidden" name="_token" value="{{ csrf_token() }}">
                  <input type="text" id="wholeProdSearch" name="searchProd" placeholder="Search" class="wholeProdSearch">
                   <i class="search link icon"></i>
               </form>

我有表单…当用户点击进入时，我试图搜索一些东西。这是js

$(document).ready(function() {
    $('input.wholeProdSearch').on( 'keypress', function (e) {
         if (e.which == 13) {
          $('#searchForm').submit();
        }
      });
  });

我有这条路线

Route::post('searchProduct','Retailer'ProductController@searchProduct');

仍然抛出错误的方法异常…使用get方法可以很好地工作，但是当我尝试这个时…它仍然抛出错误

error is
