http.request should be documented to receive an headers array #57986
Description
Affected URL(s)
https://nodejs.org/docs/latest/api/http.html#httprequesturl-options-callback
Description of the problem
It appears that the implementation of http.request allows sending headers as an array of strings, similar to response.writeHead. However, this feature is not documented. I am wondering if this is an oversight or intentionally left undocumented. If it is not intentional, I would be happy to update the documentation to reflect this functionality. I just wanted to confirm before proceeding.

From my shallow analysis of
node/lib/_http_client.js
Line 294 in 4a4aa58
Arrayhere is not something coincidentally working but rather explicitly handled as one of the possible value onoptions.headersso I thing it should be also mentioned in documentation, but of course I may be wrong 😅Edit: on the other side I found some old issue #2400 - this is about Array in Array (
[['Content-Type', 'text/plain'], ['X-Data', 'hello world']]inoptions.headersbut maybe it also has relevance in context of this issue.souravmanikandan commentedon May 31, 2025
