Question

我一直在与这个斗争几个小时。我在Symfony 2.5中构建了一个应用程序，当我以用户身份登录时收到此错误：

FatalErrorException：错误：在a上调用成员函数toArray（） /var/www/cwwa/src/CWWA/CoreBundle/Entity/Users.php中的非对象 402

在第402行，我有这段代码：

/**
 * @inheritDoc
 */
public function getRoles()
{
    //return array('ROLE_CUSTOMER_USER');
    return $this->roles->toArray();
}

如果我注释掉return $this->roles->toArray();并将其替换为上面的行，我的用户就会毫无问题地登录系统。

现在我看到其他人在使用PHP 5.4的服务器上运行Symfony2的主要问题。我的笔记本电脑正在运行，直到我将它降级到5.3。这还没有解决问题。

我使用的另一种方法是将return $this->roles->toArray();替换为return $this->roles;，我收到此错误：

可捕获的致命错误：参数4传递给 Symfony的\分量\安全\核心\认证\令牌\ UsernamePasswordToken :: __结构（）必须是一个数组，给定整数，调用 /var/www/cwwa/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Provider/UserAuthenticationProvider.php 在第96行并在中定义 /var/www/cwwa/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/UsernamePasswordToken.php 第36行

我假设系统正在从数据库中检索一个值。

我的数据库使用两个表来保证安全。一个User表和另一个是Role表。我已经为下面的用户和角色表包含了实体文件：

任何帮助都会很棒，特别是在撞墙砖4小时后！

Answer 1

在User实体中，roles字段应由users（实体另一边的字段）反转。

/**
 * @ORM\ManyToMany(targetEntity="Roles", inversedBy="users")
 */
private $roles;

您可能需要更新数据库。

Answer 2

我有类似的问题。 toArray()方法无效，因为$this->roles不是ArrayCollection的实例，而是整数。我不太明白为什么你的return构造函数中有三个Users语句;尝试先摆脱那些，然后设置你需要设置的属性：

public function __construct()
{
    $this->isActive = true;
    $this->salt = md5(uniqid(null, true));
    $this->roles = new ArrayCollection();
}

现在toArray()方法可以正常工作，因为$this->roles应该是ArrayCollection()。请记住，Symfony安全层需要一个角色对象数组或一个字符串数组。

Symfony2＆＃34;错误：在非对象上调用成员函数toArray（）＆＃34;从数据库加载角色时
