Allow only specific values for key in Joi schema
提问by mardok
Is there any other way to set specific values in Joi validation schema for key except regex pattern?
除了正则表达式模式之外,还有其他方法可以在 Joi 验证模式中为键设置特定值吗?
My example schema:
我的示例架构:
const schema = joi.object().keys({
query: joi.object().keys({
// allow only apple and banana
id: joi.string().regex(/^(apple|banana)$/).required(),
}).required(),
})

You can also use validlike
你也可以使用valid像
const schema = joi.object().keys({
query: joi.object().keys({
// allow only apple and banana
id: joi.string().valid('apple','banana').required(),
}).required(),
})

If you want to accept one or more values (apple, banana or both) you can use allow: https://hapi.dev/module/joi/api/?v=17.1.1#anyallowvalues
如果你想接受一个或多个值(苹果、香蕉或两者),你可以使用allow:https: //hapi.dev/module/joi/api/?v=17.1.1#anyallowvalues
