HTTPoison.MaybeRedirect for 308 status_code ?

fchabouis commented 2 years ago

Hi, I understand from the documentation that performing a get request on an URL responding with a 308 code should yield a HTTPoison.MaybeRedirect, allowing me to perform a redirect by hand easily.

https://hexdocs.pm/httpoison/HTTPoison.MaybeRedirect.html#t:t/0

But I get a classical %HTTPoison.Response instead.

For example :

iex(3)> HTTPoison.get("https://demo.data.gouv.fr/api/1/spatial/zones/fr:commune:44109@1943-01-01", [], [follow_redirect: true])
{:ok,
 %HTTPoison.Response{
   request_url: "https://demo.data.gouv.fr/api/1/spatial/zones/fr:commune:44109@1943-01-01",
   status_code: 308,
   body: "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 3.2 Final//EN\">\n<title>Redirecting...</title>\n<h1>Redirecting...</h1>\n<p>You should be redirected automatically to target URL: <a href=\"https://demo.data.gouv.fr/api/1/spatial/zones/fr:commune:44109%401943-01-01/\">https://demo.data.gouv.fr/api/1/spatial/zones/fr:commune:44109%401943-01-01/</a>.  If not click the link.",
   headers: [
...

Am I misunderstanding the documentation ?

(Ideally, I'd like 308 response to be automatically followed, but it seems to come from the underlying hackney lib https://github.com/benoitc/hackney/issues/635)

Thanks !

Still not released (https://github.com/benoitc/hackney/compare/1.18.1...master), available in current master.

Hackney released new versions recently, would it be possible to bump it?

starcraft66 commented 8 months ago

This should be fixed in https://github.com/edgurgel/httpoison/commit/5920e195437237f72673b0514656cedfea0b0603, would be nice to have a new release.

Hey team, HTTPoison declares hackney requirement as: [hackney](https://hex.pm/packages/hackney) ~> 1.17 so one can update hackney by doing mix deps.update hackney and that's it. No need to update HTTPoison unless hackney 2.0.0 comes out.

Tried today with

httpoison 2.1.0
hackney 1.20.1

and I get confusing results

 HTTPoison.get!("https://www.data.gouv.fr/api/1/datasets/fichier-gtfs/", follow_redirect: true)

The options (follow_redirect: true) must be the last argument. The second argument is the list of headers.

HTTPoison.get!("https://www.data.gouv.fr/api/1/datasets/fichier-gtfs/", [], follow_redirect: true)

Oh, my bad @edgurgel 🙈😬

Can confirm it works fine, thanks!
