Joi 验证：是否有一种方法可以一次性允许多个架构对象使用未知键

Question

我有几个验证器文件，其中包含近一百个模式对象。我想同时验证所有这些密钥的未知密钥。我已经找到了一种方法来验证我在下面发布的一个对象的未知密钥。有没有一种方法可以一次性完成所有事情？我正在寻找一种干的方法来做到这一点。

const schema = Joi.object().keys({
  a: Joi.string().required(),
  b: Joi.string().required()
}).unknown(true);

// or
const schema = Joi.object().keys({
  a: Joi.string().required(),
  b: Joi.string().required()
}).options({ allowUnknown: true })

You can use .defaults to create your own custom joi which in this case will have allowUnkown set true as default:

// Create your custom Joi
const customJoi = Joi.defaults((schema) => schema.options({
  allowUnknown: true 
}));

// schema using original Joi
const schema1 = Joi.object().keys({
  a: Joi.string().required(),
  b: Joi.string().required()
})

// schema using custom Joi
const schema2 = customJoi.object().keys({
  a: Joi.string().required(),
  b: Joi.string().required()
})
 
// INVALID, "c" is not allowd
schema1.validate({ a: "a", b: "b", c: 10 })
// VALID
schema2.validate({ a: "a", b: "b", c: 10 })

This also works:

var Joi = require("joi").defaults((schema) => schema.options({
  allowUnknown: true 
}));

or

var Joi = require("joi")
Joi = Joi.defaults((schema) => schema.options({
  allowUnknown: true 
}));
