1. 命令行执行 在根目录创建一个公用的测试验证类

      1. php think make:validate TestValidate

    2. TestValidate.php填写验证规则 ```javascript namespace app\common\validate;

    class TestValidate extends BaseValidate { /**

    1.  * 定义验证规则
    2.  * 格式：'字段名'    =>    ['规则1','规则2'...]
    3.  *
    4.  * @var array
    5.  */    
    6. protected $rule = [
    7.     'username'=>"require",
    8.     'email'=>"require|email"
    9. ];
    11. /**
    12.  * 定义错误信息
    13.  * 格式：'字段名.规则名'    =>    '错误信息'
    14.  *
    15.  * @var array
    16.  */    
    17. protected $message = [
    18.     "username.require"=>"用户名必须要填写哦",
    19.     "email.require"=>"邮箱必须要填写哦",
    20.     "email.email"=>"邮箱格式不正确"
    21. ];
    22. //验证场景
    23. protected $scene=[
    24.   "login"=>['username']
    25. ];

    }

    2. 3. 新建BaseValidate类
    3. ```javascript
    4. namespace app\common\validate;
    5. use app\lib\exception\BaseException;
    6. use think\Validate;
    8. class BaseValidate extends Validate
    9. {
    10.     public function goCheck($scene=false){
    11.         $data=request()->param();
    12.         $validate=$scene?$this->scene($scene)->check($data):$this->check($data);
    13.         if (!$validate) {
    14.             throw new BaseException(['msg'=>$this->getError()]);
    15.         }
    16.         return true;
    17.     }
    18. }

    1. 编写测试代码 ```javascript class Index extends Controller {

      public function index() {

      1.  (new TestValidate())->goCheck('login');

      }

    }

    2. 5. 查看结果
    3. ```json
    4. {"code":400,"msg":"邮箱格式不正确","errorCode":999}
