当两个值中的任何一个存在或缺失时的 Joi 验证

Question

Have three parameters: latitude, longitude, zipcode

I need a joi validation that

• requires latitude AND longitude when either is present OR zipcode is missing
• requires zipcode when EITHER latitude or longitude is missing.

Something like this?

Joi.object().keys({
    latitude: Joi.number().when('zipcode', { is: undefined, then: Joi.required() }),
    longitude: Joi.number().when('zipcode', { is: undefined, then: Joi.required() }),
    zipcode: Joi.number().when(['latitude', 'longitude'], { is: undefined, then: Joi.required() })
});

I'm thinking there is a more elegant solution maybe usingobject.and()

Answer 1

This solution may be useful:

 schema = Joi.object().keys({ location: Joi.object().keys({ lat: Joi.number(), long: Joi.number() }).and('lat', 'long'), timezone: Joi.alternatives() .when('location', { is: null, then: Joi.number().required(), otherwise: Joi.number() }) });

You can validate multiple conditions in the following schema.

 const schema = Joi.object().keys({ searchby: Joi.string().valid('phone', '_id', 'cno').required(), // field name searchvalue: Joi .when('searchby', { is: "phone", then: Joi.string().regex(/^(923)\\d{9}$/, 'numbers').max(12).min(12).required() }) .when('searchby', { is: "_id", then: Joi.objectId().required() }) .when('searchby', { is: "nic", then: Joi.number().required() }) });
