Clear headers from specific requests in hurl file

[aranw]

I have this hurl file that will make a request to an endpoint which will return a presigned url

I then use that presigned url to upload a file but the issue I'm having is I set the authorization header via the --header flag and I'd like to exclude that header from the request that is made to the presigned url

# ─── Get S3 presigned upload URL ──────────────────────────────────────────────
PUT {{base_url}}/upload
[Options]
location: false

HTTP 307
[Captures]
upload_url: header "Location"


# ─── Upload file to S3 ────────────────────────────────────────────────────────
PUT {{upload_url}}
Content-Type: image/png
[Options]
location: false
file,testdata/logo.png;

HTTP 200

Is there a way to make the second request not include the --header authorization?

Hi @aranw

Indeed, --header applies a header on all the requests inside a file. Currently, there is no simple way to delete a header (contrary to libcurl, Hurl's HTTP engine)

Sorry for the obvious suggestion but, in this case, couldn't you set the header on the first request, and not set it on the following requests (by not using --header)?

# ─── Get S3 presigned upload URL ──────────────────────────────────────────────
PUT {{base_url}}/upload
Authorization: XXX
[Options]
location: false

HTTP 307
[Captures]
upload_url: header "Location"


# ─── Upload file to S3 ────────────────────────────────────────────────────────
PUT {{upload_url}}
Content-Type: image/png
[Options]
location: false
file,testdata/logo.png;

HTTP 200

This supports also variables that you can inject:

# ─── Get S3 presigned upload URL ──────────────────────────────────────────────
PUT {{base_url}}/upload
Authorization: {{token}}
[Options]
location: false
HTTP 307
[Captures]
upload_url: header "Location"

What I'm trying to achieve is depending on which environment these requests are being called against I use different headers.

E.g. for e2e tests I want to use an authorization header. For local tests or tests I run in cluster I want to use different custom headers that are set via our api gateway. What I don't want is the headers than I'm not expecting not to be included with empty strings

If i understand your use case, you want to run for instance :

$ hurl --header "x-foo:FOO" --header "x-bar:BAR" test.hurl

And in the Hurl file:

# This request has `x-foo` header and `x-bar` header
GET https://example.com
HTTP 200


# This request has only `x-foo` header
# Syntax TBD
GET https://example.com
[Options]
no-header: x-bar
HTTP 200

is this correct?

Yeah that's exactly what I'm thinking. Right now my current workaround is using variables but it means i got headers being passed in my requests with empty strings
