How can i use content negotiation when validate data?

[nandordudas]

Im using windows 10 with wsl 2 and just start project with yarn start - node v14.5.0.

Im using insomnia, but its uses this part of code.

#!/usr/env bash

curl -X POST localhost:3333 \
  -H 'accept: application/vnd.api+json' -H 'content-type: application/json' -d '{"username":""}'

Route.post('/', async ({ request }) => (await request.validate(class {
  public schema = schema.create({username: schema.string()})
})))
// {"errors": [{"rule": "required", "field": "username", "message": "required validation failed"}]}

But, if accept part is hardcoded then it works.

Route.post('/', async ({ request }) => {
  request.request.headers.accept = 'application/vnd.api+json'
  await request.validate(class {
    public schema = schema.create({username: schema.string()})
  })
})
// {"errors": [{"code": "required", "source": {"pointer": "username"}, "title": "required validation failed"}]}

What is im doing wrong?

Hey @nandordudas! 👋

If you want to have JSON API format back you need to send the Accept header everytime.
You can also force the Accept in your configuration config/app.ts.

Note that you are using the validator wrong.
You shouldn't pass an anonymous class.

Thanks!

Yes, this is a very bad example! Only for demo, no one use it 😃
