New submission from rosoroso <robert.calv...@ibm.com>:
When using the urllib request headers, I've found that certain letters are converted to their lowercase versions whilst part of a request object (H->h in the example, see at bottom). Whilst this should not usually be an issue (Since headers are not supposed to be case sensitive), I've found an API for which that is not the case. Options for fixing this could include, not changing the case of characters in header fields or updating the docs to include a warning of this behaviour (https://docs.python.org/3/library/urllib.request.html) import urllib.request header = {"Test-Header":"Value"} requestobject = urllib.request.Request("https://www.example.com",None,header) print ("Original header is:", header) print ("Request header is:", requestobject.header_items()) ''' Orginal header is: {'Test-Header': 'Value'} Request header is: [('Test-header', 'Value')] Version was Python 3.6.5 ''' ---------- messages: 356813 nosy: rosoroso priority: normal severity: normal status: open title: urllib.request header characters being changed to lowercase type: behavior versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38831> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
