The laravel validation rule only accept value, that's mean required_unless:facebookID,nullis evaluated as: the field is required unless facebookID='null'. So it's not a case you would need.
Laravel 验证规则只接受值，这意味着required_unless:facebookID,null被评估为：该字段是必需的，除非 facebookID='null'。所以这不是你需要的情况。
My suggest solution is using require_without_all:
我建议的解决方案是使用 require_without_all：
'email' => 'required_without_all:facebookID,googleID',
'password' => 'required_without_all:facebookID,googleID'
