```js

class HomeController extends Controller {

  async index() {

    const { app, ctx } = this;

    const messages = { 'username.alpha': '该字段应该为长度为6的字母串' };

    const errors = await app.validator.validate(ctx.request.body, rule, messages);

    if (errors) {

      // ...

    } else {

    }

  }

}

```

      //... return a boolean

    }

  },

  messages: {

    custom: 'a custom message...',
