Question

将Joi升级到最新版本@ hapi / Joi（17.1.1）后，我的服务器没有启动，我在启动时遇到错误。似乎最新版本中有一些重大更改。尚无任何线索，不胜感激。

Answer 1

我认为您应该执行以下操作来处理此错误：

    var ObjectJoi = Joi.object({
    //some item that you want to add

})

var mySchema = new Schema(Joigoose.convert(ObjectJoi))
const myModel = mongoose.model('myModel', mySchema);

Answer 2

不看代码就很难分辨。
但是在使用Joi.extend()时我遇到了同样的问题。

const extendedType = Joi.extend(Joi => {
  return {
    type: 'myType', // <- PAY ATTENTION
    base: Joi.array(),
    messages: {
      'stringArray:base': '...'
    },
    validate(value, helpers) {
      ...
    },
    coerce(value, helpers) {
      ...
    }
  }
});

问题是我像下面这样错误地使用了extendedType：

Joi.object({
  someKey: extendedType,
  ...
});

代替：

Joi.object({
  someKey: extendedType.myType(),
  ...
});

Answer 3

感谢您的评论。在阅读了Joi的发行说明后，我能够解决它。

问题出在Joi版本的混合。在我的代码库中，使用了Joi的较早版本，这导致了这种情况。下面的Github问题帮助我意识到了这个问题。

将Joi升级到最新版本后出错-模式只能包含普通对象（名称）
