How to allow any other key in Joi
提问by Anand Undavia
I have a simple requirement. I tried to search on the internet as well as documentation but failed.
So here is what I want to achieve:
我有一个简单的要求。我试图在互联网和文档上进行搜索，但失败了。
所以这就是我想要实现的目标：
I have a schema:
我有一个架构：
const schema = Joi.object().keys({
a: Joi.string().required(),
b: Joi.string().required()
});
Now, How do I configure it such that any other key in the object would be allowed?
With this schema, it only allows two keys aand b. If I pass any other key, say, c, it throws an error saying that cis not allowed.
现在，如何配置它以便允许对象中的任何其他键？
使用此架构，它只允许两个键a和b。如果我传递任何其他键，例如，c它会抛出一个错误，指出这c是不允许的。

You can add unknown keys using object.pattern(regex, schema)this way IF you want to make sure these unknown keys are strings:
如果您想确保这些未知键是字符串，您可以通过这种方式使用object.pattern(regex, schema)添加未知键：
const schema = Joi.object().keys({
a: Joi.string().required(),
b: Joi.string().required()
}).pattern(/./, Joi.string());For a general pass of all key types use object.unknown(true):
对于所有键类型的通用传递，使用object.unknown(true)：
const schema = Joi.object().keys({
a: Joi.string().required(),
b: Joi.string().required()
}).unknown(true);

The correct answer is actually to use object.unknown(true).
正确答案实际上是使用object.unknown(true).
const schema = Joi.object().keys({
a: Joi.string().required(),
b: Joi.string().required()
}).unknown(true);
