How to access request headers when mocking?

[suneettipirneni]

Nock has a functionality where you can provide a function to access the request data like so:

.reply(200, function handler() {
	return { example: this.req.headers.example };
})

However I'm not sure how do the same thing with undici mocking. I've looked at the docs, but still no luck. Any assistance would be greatly appreciated.

Hi @suneettipirneni ,
this seems to be already supported.
if you try the example in the doc and add a function instead of an object in the reply

mockPool.intercept({
  path: '/bank-transfer',
  method: 'POST',
  headers: {
    'X-TOKEN-SECRET': 'SuperSecretToken',
  },
  body: JSON.stringify({
    recepient: '1234567890',
    amount: '100'
  })
}).reply(200, (...all) => {
  console.log('all', all)
  return {
    message: 'transaction processed'
  }
})

the argument of that function will be the options given to the intercept function

all [
  {
    method: 'POST',
    headers: { 'X-TOKEN-SECRET': 'SuperSecretToken' },
    body: '{"recepient":"1234567890","amount":"100"}',
    origin: 'http://localhost:3000',
    path: '/bank-transfer'
  }
]

is that what you were after?

Whoops! I should've marked this as answered since I made the PR to add this functionality 😂

perfect, I did not realized it was you in the commits 😅

@suneettipirneni looking at the doc there is no mention of this https://undici.nodejs.org/#/docs/best-practices/mocking-request , should I open a PR adding a small paragraph about it? or is it somewhere else I missed?
