我正在跟随Web API REST with Symfony2使用Fosrestbundle和JMS Serializer在symfony2中构建REST API，并且对于GET路由完美但不是POST，因为当我验证表单时总是返回false，甚至我都遵循函数的流程和最后一步在$ form-＆gt; isValid（）中返回true，所以我很困惑。
甚至没有考虑到validations.yml文件所以，是很多代码但希望你可以帮助我因为两天我一直试图找出问题

似乎有两种简单的方法可以为您的实体设置约束。
在yml中创建Bundle文件：
# src/Acme/BlogBundle/Resources/config/validation.yml
Acme\BlogBundle\Entity\Author:
properties:
name:
- NotBlank: ~
为了使其自动运行，重要的是该文件具有相同的名称并且位于该确切的路径中。然后，您启用验证并禁用注释。
# app/config/config.yml
framework:
validation: { enabled: true, enable_annotations: false }
您不需要任何特殊文件。只需在Entity的属性中指定约束：
// src/Acme/BlogBundle/Entity/Author.php
use Symfony\Component\Validator\Constraints as Assert;
class Author
{
/**
* @Assert\NotBlank()
*/
public $name;
}
请记住启用注释：
# app/config/config.yml
framework:
validation: { enable_annotations: true }
如果您想使用 validation.yml和注释，或者您想为验证文件使用不同的名称或路径，则必须手动加载它们。
