仅当另一个具有特定值时,Node Js Express Validator必填字段

med*_*ifi 6 javascript validation node.js express

我使用express-validator来检查我的帖子字段.我的问题是我想只在其他字段具有特定值时才需要一些字段.例如:

if person_organisation is true:
person_organisation_name must be required

if person_organisation is false:
person_first_name must be required

有没有办法把这个规则放在验证模式中?

创建自定义验证:

app.use(expressValidator({
 customValidators: {
    checkPersonName: function(name, isPerson) {
        return isPerson === true ? name != '' : true;
    },
    checkOrganisationName: function(name, isPerson) {
        return isPerson === false ? name != '' : true;
    }
 }
}));

并使用:

app.post('/registration', function(req, res) {

  req.checkBody(
    'person_first_name', 'Please provide Your first name'
  ).checkPersonName(req.body.person_organisation);

  req.checkBody(
    'person_organisation_name', 'Please provide valid organisation name'
  ).checkOrganisationName(req.body.person_organisation);

  req.getValidationResult().then(function(result) {
    if (!result.isEmpty()) {
      res.status(400).send({result: result.array()});
      return;
    }

    res.json(); // when success do something
  });
});
