升级 Joi 至最新版本后出现错误 - Schema 只能包含普通对象 (名称)

Question

将Joi升级到最新版本@hapi/Joi（17.1.1）后，我的服务器无法启动，在启动时出现以下错误。最近的版本中似乎有一些破坏性变化。目前还没有找到任何线索，感谢任何帮助。

我能看一下你的模式代码和模型导出吗？ - Badri Derakhshan

Answer 1

对于那些再次陷入这个黑暗境地的人，对我来说，这是在使用扩展运算符扩展Joi模式时出现的问题：

joi.object().keys({
   ...otherSchema,
   position: joi.number()
})

当我升级到Joi 17.5.0时，这导致了“Schema can only contain plain objects”错误。使用keys()语法解决了这个问题：

otherSchema.keys({
   position: joi.number()
})

Answer 2

感谢大家的评论。在阅读Joi的发布说明后，我成功地解决了这个问题。

问题出在Joi版本混合使用上。我的代码库中使用了较旧的Joi版本，导致了这个问题。下面的Github问题帮助我意识到了这个问题。

Answer 3

没有看到代码很难说。
但是我在使用 Joi.extend() 时遇到了相同的问题。

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

问题在于我错误地使用了以下代码：

extendedType

。

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

改为：

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

Answer 4

我认为你应该像这样处理这个错误：

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

})

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