有没有办法验证 Joi 模式中的动态键名? [英] Is there a way to validate dynamic key names in a Joi schema?

问题描述

有没有一种方法可以使用 Joi 验证这样的值，以便我可以验证它是一个具有零个或多个键(任何名称)的对象，并且每个键的值都为字符串、数字还是布尔值?

Is there a way I can validate a value like this with Joi so that I can verify it is an object with zero or more keys (of any name) and that each have values of either a string, number or boolean?

{
  dynamicallyNamedKey1: 'some value',
  dynamicallyNamedKey2: 4
}

推荐答案

你会想要使用 Joi 的 object().pattern() 方法.它专门用于验证具有未知密钥的对象.

You're going to want to use Joi's object().pattern() method. It's specifically for validating objects with unknown keys.

要匹配单个键上的一个或多个数据类型，您需要 alternatives().try()(或简单地传递 Joi 类型的数组).

To match against one or more datatypes on a single key you'll need alternatives().try() (or simply pass an array of Joi types).

因此，满足您需求的规则是:

So the rule to match your needs would be:

Joi.object().pattern(/^/, Joi.alternatives().try(Joi.string(), Joi.number(), Joi.boolean()))
