在 CakePHP 的无模型表单中找不到类 ContactForm

Question

我在我的应用程序中使用无模型表单，我遵循 CakePHP 无模型 guid，但我遇到了错误。 我尝试了不同的方法来解决问题，但没有成功，请帮助我。

找不到类“ContactForm”。

在 Controller\ContactController.php 中显示错误，第 20 行

您忘记为表单提供命名空间。
你的文件src/Form/ContactForm.php 应该这样开始：

<?php
namespace App\Form;

use Cake\Form\Form;
use Cake\Form\Schema;
use Cake\Mailer\Email;
use Cake\Validation\Validator;


class ContactForm extends Form {
