我定义了一个选民，特别是voteOnAttribute如下方法：
public function voteOnAttribute($attributes, $subject, TokenInterface $token) {
$user = $token->getUser();
if (!$user instanceof User) {
return false;
// return static::ACCESS_DENIED
}
if(!$subject instanceof PrivateResource) {
throw new Exception('Media type mismatch : private resource expected here');
}
// Check company is elligible here
if(!$subject->getCompanies()->contains($user->getCompany())){
return false;
// return static::ACCESS_DENIED
}
return static::ACCESS_GRANTED;
}
为什么我不能在我的方法中使用VoterInterface常量 ( ACCESS_GRANTED, ACCESS_ABSTAIN, ACCESS_DENIED)？
如果我这样做，由于vote抽象类中的方法，不会强制执行拒绝访问决定Voter：
public function vote(TokenInterface $token, $subject, array $attributes)
{
// abstain vote by default in case none of the attributes are supported
$vote = self::ACCESS_ABSTAIN;
foreach ($attributes as $attribute) {
if (!$this->supports($attribute, $subject)) {
continue;
}
// as soon as at least one attribute is supported, default is to deny access
$vote = self::ACCESS_DENIED;
if ($this->voteOnAttribute($attribute, $subject, $token)) {
// grant access as soon as at least one attribute returns a positive response
return self::ACCESS_GRANTED;
}
}
return $vote;
}
由于ACCESS_DENIED常量在 中设置为 -1 VoterInterface，因此if ($this->voteOnAttribute($attribute, $subject, $token))条件为真，即使返回值为 -1。
我在这里误会了什么？这些常量是否计划在我们的自定义voteOnAttribute方法中使用？
注意：我将选民策略设置unanimous为security.yml
