## 代码 注意，看 `edit` 场景 ``` <?php namespace app\agent\validate; use think\Validate; class UserValidate extends Validate { protected $rule = [ 'user_login' => 'require|unique:user,user_login', 'user_pass' => 'require', 'user_email' => 'require|email|unique:user,user_email', ]; protected $message = [ 'user_login.require' => '用户不能为空', 'user_login.unique' => '用户名已存在', 'user_pass.require' => '密码不能为空', 'user_email.require' => '邮箱不能为空', 'user_email.email' => '邮箱不正确', 'user_email.unique' => '邮箱已经存在', ]; protected $scene = [ 'add' => ['user_login', 'user_pass', 'user_email'], 'edit' => ['user_login', 'user_email'], ]; } ```
