使用LinValidator报错
定义：
const { Rule, LinValidator } = require('lin-mizar') 
class test extends LinValidator{
  constructor(){
    super()
    this.test =[
      new Rule('isInt','测试')
    ]
  }
}
module.exports = {test}
使用：
router.get('/:test/error',(ctx,next)=>{
  const res =  new Test().validate(ctx)
  console.log(res)
})
报错：
E:\work\Node\execrise\koa\node_modules\lin-mizar\lin\exception\http-exception.js:10
    throw new Error('CodeMessage.getMessage() must be implemented');
