小编Cyb*_*101的帖子

我已经创建了一个用户注册表,就像在文档中一样.稍后我想添加CSRF.从那以后它再也不能正常工作了.我安装并删除了包. https://symfony.com/doc/current/doctrine/registration_form.html

composer require security-csrf
composer remove security-csrf
rm -rf vendor
rm -rf var/cache/*

这没有用.

当我填写表格并提交.如果用户已保存.我第二次,我收到下面的错误消息.

只有当我在浏览器中删除cookie"PHPSESSID"时,我才能再次发送表单.之后再次出现同样的问题.

PDOException:

我试着调试一下.交易在某处激活,然后不再激活.我找不到问题.有人能帮助我吗？

的symfony /配置/ services.yaml

services:
    Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler:
        arguments:
            - !service { class: PDO, factory: 'database_connection:getWrappedConnection' }
            - { db_table: session, db_username: username, db_password: password }

我想将 json 转换为对象/模型。如果 json 只是一维的，它可以完美地工作。

但是如果它是多维的，则只转换外部（用户），而不转换内部（公司），这仍然是一个数组。你能帮我解决这个问题吗？

模型：

<?php
namespace AppBundle;

class Company {
    /**
     * @var string
     */
    protected $companyName = '';

    /**
     * @return string
     */
    public function getCompanyName()
    {
        return $this->companyName;
    }

    /**
     * @param string $companyName
     * @return void
     */
    public function setCompanyName($companyName)
    {
        $this->companyName = $companyName;
    }
}

class User {
    /**
     * @var \AppBundle\Company
     */
    protected $company = null;

    /**
     * @var string
     */
    protected $username = '';

    /**
     * @return \AppBundle\Company
     */
    public function …
