namespace app\api\validate;
use think\Validate;
class IdMustInt extends Validate
{
protected $rule = [
'id' => 'require|IsInt'
];
protected function IsInt($value,$rule,$data,$field){
//参数依次为验证数据，验证规则，全部数据（数组），字段名
//这里我们要判断的验证的数据要求必须为正整型
if(is_numeric($value) && is_int($value+0) && ($value+0) > 0){
return true;
}else{
//如果不符合我们的条件，返回错误信息，在控制器中可以用getError()方法输出
return $field.'不是整型';
}
}
}Next, let’s look at our controller The corresponding operations
public function getBanner($id)
{
//需要验证的数据
$data = [
'id' => $id,
];
//实例化验证器
$validate = new IdMustInt();
//如果验证数据较多，条件也较多，需要批量返回所有错误信息的话，可以在check()前加上$validata->batch()
$result = $validate->check($data);
if($result){
//业务逻辑
}else{
dump($validate->getError());
}
