RTSPS scheme support in urllib.parse #104554
Description
In accordance with
https://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml
There are three valid RTSP schemes:
| URI Scheme | Description | Status | Reference |
|---|---|---|---|
| rtsp | Real-Time Streaming Protocol (RTSP) | Permanent | [RFC2326][RFC7826] |
| rtsps | Real-Time Streaming Protocol (RTSP) over TLS | Permanent | [RFC2326][RFC7826] |
| rtspu | Real-Time Streaming Protocol (RTSP) over unreliable datagram transport | Permanent | [RFC2326] |
But in urllib/parse.py only two of them are defined:
- rtsp
- rtspu
What make impossible to use functions like urllib.parse.urljoin() upon rtsps://* URLs:
Type "help", "copyright", "credits" or "license" for more information. >>> from urllib.parse import urljoin >>> urljoin('rtsps://127.0.0.1/foo/bar', 'trackID=1') 'trackID=1' Expected result is:
Type "help", "copyright", "credits" or "license" for more information. >>> from urllib.parse import urljoin >>> urljoin('rtsps://127.0.0.1/foo/bar', 'trackID=1') 'rtsps://127.0.0.1/foo/trackID=1' >>> I was able to get the expected behavior by patching urllib/parsing.py:
