How does thinkphp6 use the validator to output information to the front-end page?

Question

public function checkLogin (Request $request)

{

$status = 0;

$result = 'Default value';

$ data = $request->param();

$result = validate(UserValidate::class)->check($data);

// If it is found during the test that the field verification fails, the execution will not proceed.

If($result){

$result = 'Verification successful';

$status = 1;

#} Else {

# Validate ()-& GT; Geterror ();

##}

return ['status'=>$status, 'message'=>$result, 'data'=>$data];

}

<?phpnamespace app\validate;use think\Validate;class User extends Validate{

protected $rule = [

'name|username' => 'require' ,    

'password|password' => 'require',  

'verify|verification code' => 'require|captcha', 

];  protected $ message = [

'name|Username.require' => 'Name must be filled in',

'password|Password.require' => 'Password required',

'verify.require' => 'Verification code must be filled in',

'verify.captcha' => 'Verification code error',

];}
