hapi.js - 数组的Joi验证

Question

尝试验证数组在一种情况下是否有零个或多个字符串，以及在另一种情况下是否有零个或多个对象，与 Joi 文档作斗争:(

validate: {
    headers: Joi.object({
            'content-type': "application/vnd.api+json",
            accept: "application/vnd.api+json"
    }).options({ allowUnknown: true }),
    payload : Joi.object().keys({
        data : Joi.object().keys({
            type: Joi.any().allow('BY_TEMPLATE').required(),
            attributes: Joi.object({
                to : Joi.string().email().required(),
                templateId : Joi.string().required(),
                categories : Joi.array().items( //trying to validate here that each element is a string),
                variables : Joi.array({
                    //also trying to validate here that each element is an Object with one key and value
                })
            })
        }).required()
    })
}

Answer 1

Joi.array().items() 接受另一个 Joi 模式来针对数组元素使用。所以字符串数组就是这么简单:

Joi.array().items(Joi.string())

对于对象数组也是如此；只需将对象模式传递给 items():

Joi.array().items(Joi.object({
    // Object schema
}))
