将 Joi 升级到最新版本后出错 - 架构只能包含普通对象（名称）

Question

将 Joi 升级到最新版本 @hapi/Joi(17.1.1) 后，我的服务器没有启动，我在启动时遇到以下错误。最近的版本似乎有一些重大变化。还没有得到任何线索，感谢任何帮助。

Answer 1

对于再次发现自己处于这个黑暗地方的任何人，对我来说，使用扩展运算符扩展 Joi 模式是一个问题：

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

当我升级到 Joi 17.5.0 时，这导致了“架构只能包含普通对象”错误。使用 keys() 语法绕过它：

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

感谢大家的 cmets。在浏览了 Joi 的发行说明后，我能够解决它。

问题是由于 Joi 版本的混合造成的。在我的代码库中使用了旧版本的 Joi，这导致了这种情况。下面的 Github issue 帮助我意识到了这个问题。

Answer 3

不看代码很难判断。
但是我在使用Joi.extend() 时遇到了同样的问题。

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

问题是我错误地使用了extendedType，如下所示：

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

代替：

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

我认为你应该做这样的事情来处理这个错误：

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

})

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