使用 Joi 验证 object 的两个键是否应该具有相同的值？

Question

I am using Joi for object dalidation.
suppose my object is

// valid object
object1 = {
    "minimum_balance": 200,
    "initial_amount": 200,
    "name": "Alok"
}

// invalid object
object2 = {
    "minimum_balance": 250,
    "initial_amount": 200,
    "name": "Alok"
}

I want to add validation to this object that minimum_balance and initial_amount should be same using joi . I should get error if values of both key are not same.

Answer 1

try this

const minimum_balance = Joi.string().required().valid(Joi.ref('initial_amount')).options({
  language: {
    any: {
      allowOnly: '!!initial amount do not match',
    }
  } 
})

Answer 2

var schema = Joi.object().keys({
  fieldOne: Joi.string().required(),
  fieldTwo: Joi.string().allow(Joi.ref('fieldOne')).required()
});
