Do http datasources support POST calls, or only GET?

[richgerrard]

Hi!
I had an API change from a GET call to a POST call in a new release, and my datasource fails as follows:

error calling ds: Couldn't read datasource 't': Unexpected HTTP status 404 on GET from https://t.x.y/api/v1/daemonset.yaml?type=application/yaml: 404 page not found\n"

Is this configurable? Docs mentioned headers, but not methods.
Thank you!

Hey @richgerrard! 👋

That's a pain. POST isn't supported - generally because it tends to model a write, and gomplate datasources are all about reading.

Is this particular POST looking for a body to be sent, or can it be empty? If so I could probably add support pretty easily.

One thing you could try is setting the X-HTTP-Method-Override header to POST (i.e. --datasource-header t="X-HTTP-Method-Override=POST") - some proxies & APIs support that. But it's a long shot.

Thanks! Will give that a go first!

@richgerrard just curious if this worked for you? If so could you mark it as answered? 🙂
