fix(scripts): keep {{variables}} intact in req.getHost()#9240dhananjaypesu wants to merge 1 commit into
Conversation
In a pre-request script req.url has not been interpolated yet, and
getHost() ran it through new URL(), which mishandles a {{var}} in the
authority:
- `{{HOST}}/test` has no scheme, so new URL() throws and getHost()
returned '' (usebruno#9233).
- `https://{{HOST}}/test` parses, but the host is lowercased to
`{{host}}`, which bru.interpolate() then no longer resolves (usebruno#9234).
When the authority of the raw URL holds a {{variable}}, read it straight
from the string instead - scheme, userinfo, path, query and fragment
removed, case left alone. Any other URL still goes through new URL(), so
a literal host comes back exactly as before.

Handle unresolved schemes in getRawHost
When this.req.url is {{protocol}}://{{HOST}}/path, the scheme pattern does not match. getRawHost() returns {{protocol}}:, so BrunoRequest.getHost() exposes the wrong value to pre-request scripts. For example, bru.interpolate(req.getHost()) produces https: instead of the host. Strip unresolved {{...}}:// prefixes before extracting the authority, and add this case to bruno-request-get-host.spec.js.

Description
req.getHost()loses a{{variable}}that sits in the host part of the URL. In a pre-request script the URL has not been interpolated yet, andgetHost()handed it tonew URL():{{HOST}}/testhas no scheme, sonew URL()throws andgetHost()returns''.https://{{HOST}}/testparses, but the host comes back lowercased as{{host}}, sobru.interpolate(req.getHost())no longer resolves it.Problem
Fixes #9233
Fixes #9234
Both are the same function mishandling the same input, so they are fixed together.
Fix
If the authority of the raw URL contains
{{,getHost()now reads it straight from the string: scheme, userinfo, path, query and fragment stripped, case left alone. Any other URL still goes throughnew URL(), so a literal host is returned exactly as before (lowercased, port included).One thing to call out for #9233: when the variable holds the scheme as well (
HOST=https://example.com),getHost()returns{{HOST}}. The host can't be separated from the scheme until the variable is interpolated, butbru.interpolate(req.getHost())now gives the value back instead of an empty string.Tests
Added
packages/bruno-js/tests/bruno-request-get-host.spec.js(9 cases). The 5 cases with placeholders fail onmainand pass with this change; the other 4 pin the existing behaviour for literal hosts. ESLint is clean on both files.Screenshots
n/a, no UI change.
