UsernamePasswordToken::__construct()的第四个参数应该是一个数组,但它是null.它在UserAuthenticationProvider at line 96被召集.
如果您查看该代码,您将看到UsernamePasswordToken :: __ construct()的第4个参数是$roles.所以这应该是一个数组,但它变为null.
我猜你有written your own User entity,并且你的用户实体的getRoles()方法返回null而不是一组角色.所以只需将该方法更改为：
/**
* Returns the roles granted to the user.
*
* @return Role[] The user roles
*/
public function getRoles()
{
return array('ROLE_USER');
}
当然,只要getRoles()返回字符串数组或Role对象,实际代码可能会有所不同(您可能希望将用户角色存储在数据库中).
