验证 AdonisJs 5 中的对象数组

Question

i'm developing a RestAPI using AdonisJs 5 and i'm trying to validate the request body to be an array of objects which i don't know what properties it may contain so i don't want to specify any properties. the payload is something like this

{
    "gap": [
        {
            "1": "small"
        },
        {
            "2": "x"
        },
        {
            "a": "king" 
        }
    ]

}

where the keys represents something for the business logic. i tried to do it in a couple of ways and neither of them work

1. by adding empty object to the members function

public schema = schema.create({
    gap: schema.array.optional().members(schema.object().members({})),
  })

but the result was an array of empty object since adonis neglect any extra data that wasn't provided in the validator schema 2. passing only the schema.object without the members function

public schema = schema.create({
    gap: schema.array.optional().members(schema.object()),
  })

but this results an error

Answer 1

There is.anyMembers() option.

Read about it here: https://docs.adonisjs.com/reference/validator/schema/object#accept-any-elements

So your solution would be:

public schema = schema.create({
    gap: schema.array.optional().members(schema.object().anyMembers()),
  })
