From 13a10d5aa336be7c301a6d09eb4e9d7b50f51191 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sergey=20M=E2=80=A4?= Date: Fri, 20 Nov 2015 03:08:01 +0600 Subject: [PATCH] [compat] Add compat_urllib_request_Request This is actually not a compatibility routine but rather a workaround for URLs without protocol specified. The protocol-less URL is treated as HTTP one since it's most probable scenario and it will most likely to redirect to HTTPS if HTTPS was actually expected. This routine could also be useful for any Request preprocessing that may be added in future. --- youtube_dl/compat.py | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/youtube_dl/compat.py b/youtube_dl/compat.py index a3e85264a..4e3de7f51 100644 --- a/youtube_dl/compat.py +++ b/youtube_dl/compat.py @@ -198,6 +198,14 @@ except ImportError: # Python < 3.4 return compat_urllib_response.addinfourl(io.BytesIO(data), headers, url) + +# Prepend protocol-less URLs with `http:` scheme in order to mitigate the number of +# unwanted failures due to missing protocol +def compat_urllib_request_Request(url, *args, **kwargs): + return compat_urllib_request.Request( + 'http:%s' % url if url.startswith('//') else url, *args, **kwargs) + + try: compat_basestring = basestring # Python 2 except NameError:
