我正在尝试使用ValidatorInterface在控制器中验证使用ajax提交的表单。

但是我得到这个错误：

无法解析“ App \ SocialStudio \ AdminBundle \ Controller \ InfluencersController :: addinfluencerajax（）”的参数$ validator，也许您忘记了将控制器注册为服务或错过了使用“ controller.service_arguments”对其进行标记的操作？ / p>

这是我的控制者：

<?php
namespace App\SocialStudio\AdminBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use App\Entity\Influencer;
use App\Form\Type\InfluencerType;

use Symfony\Component\Validator\Validator\ValidatorInterface;

class InfluencersController extends AbstractController
{
    public function Influencers(Request $request)
    {   
        // Get all Inlfuencers
        $influencers = $this->getDoctrine()
            ->getRepository(Influencer::class)
            ->findAll();

        // create modal form
        $influencer = new Influencer();
        $addInfluencerForm = $this->createForm(InfluencerType::class,$influencer);

        return $this->render('@Admin/influencers.html.twig',[
            'menu' => 'influencers','influencers' => $influencers,'addInfluencerForm' => $addInfluencerForm->createView(),]);

    }

    public function addInfluencerAjax(Request $request,ValidatorInterface $validator)
    {   

        ... form handling happens in this function ...

    }

}

这是我的ajax调用代码：

$('#submitAddInfluencerForm').click(function(e){
           e.preventDefault();
            addInfluencerForm = $('#addInfluencerForm').serialize();

            $.ajax({
                url:'{{ path('AddInfluencerAjax') }}',type: "GET",dataType: "json",data: {
                    "influencer": addInfluencerForm
                },async: true,success: function (return_data)
                {
                    ...
                }
            });

        });

services.yaml

services:
  _defaults:
    autowire: true
    autoconfigure: true

  App\:
    resource: '../src/*'
    exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

  App\Controller\:
    resource: '../src/Controller'
    tags: ['controller.service_arguments']

然后我将其放入我的framework.yaml

framework:
   validation: { enable_annotations: true }
