如何使用Joi验证其键应与外部对象匹配的嵌套对象，另一个键的值应为数组? [英] How to validate nested object whose keys should match with outer objects another key whose value is array using Joi?

问题描述

我有要验证的对象.

// valid object because all values of keys are present in details object
var object = {
    details: {
        key1: 'stringValue1',
        key2: 'stringValue2',
        key3: 'stringValue3'
    },
    keys: ['key1', 'key2', 'key3']
}

// invalid object as key5 is not present in details
var object = {
    details: {
        key4: 'stringValue4'
    },
    keys: ['key4', 'key5']
}

// invalid object as key5 is not present and key8 should not exist in details
var object = {
    details: {
        key4: 'stringValue4',
        key8: 'stringValue8',            
    },
    keys: ['key4', 'key5']
}

keys中存在的所有键也应该存在于details中.

All the keys present in keys should be present in details also.

我尝试使用 Joi.ref() >

var schema = Joi.object({
    details: Joi.object().keys(Object.assign({}, ...Object.entries({...Joi.ref('keys')}).map(([a,b]) => ({ [b]: Joi.string() })))),
    keys: Joi.array()
})

但是这不起作用，因为Joi.ref('keys')将在验证时得到解决.

But this is not working because Joi.ref('keys') will get resolved at validation time.

如何使用 Joi 验证该对象?

推荐答案

使用 object.pattern 和 stackblitz
