New submission from Jairo Llopis <yajo....@gmail.com>:
urllib.request.HTTPRedirectHandler fails if there is a 307 HTTP return code in a POST request. In https://github.com/python/cpython/commit/c379bc5ec9012cf66424ef3d80612cf13ec51006 the same behaviour was implemented for 308. According to https://datatracker.ietf.org/doc/html/rfc7538#section-3 IMHO this implementation is wrong for 308: > Note: This status code is similar to 301 (Moved Permanently) > ([RFC7231], Section 6.4.2), except that it does not allow changing > the request method from POST to GET. A similar note exists in https://datatracker.ietf.org/doc/html/rfc7231#section-6.4.7 regarding code 307. So, as long as the original redirection is in POST and it gets redirected to another POST, it should not be an error. FWIW, in https://github.com/traefik/traefik/issues/7829#issuecomment-770210080 you can see that Traefik proxy uses 307 and 308 codes by default when redirecting non-GET requests. Thus, urllib.request.HTTPRedirectHandler will fail to process any POST requests proxied by Traefik. ---------- components: Library (Lib) messages: 416249 nosy: Jairo Llopis priority: normal severity: normal status: open title: HTTPRedirectHandler fails on POST for 307 and 308 type: behavior versions: Python 3.10, Python 3.11, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47150> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
