# 驗證類 驗證類的位置在 app\validate文件夾下 所有的驗證類都繼承自Validate類，具體的使用請參考THINKPHP相關文檔。 ``` class User extends Validate { //用戶名或密碼的規范可能是從數據庫中獲取的 protected $rule = [ 'username' => 'require|unique:sys_user', 'real_name' => 'requireWithout:field|requireIf:field,real_name', 'password' => 'require', ]; protected $message = [ 'username.require' => 'validate_user.username_require', 'username.unique' => 'validate_user.username_unique', 'username.max' => 'validate_user.username_max', 'real_name.requireWithout' => 'validate_user.real_name_require', 'real_name.requireIf' => 'validate_user.real_name_require', 'password.require' => 'validate_user.password_require', ]; protected $scene = [ 'add' => ['username','password'], 'edit' => [], 'modify' => [] ]; } ```
