"""
The Request.headers dictionary is not a documented interface. It should
stay that way, because the complete set of headers are only accessible
through the .get_header(), .has_header(), .header_items() interface.
However, .headers pre-dates those methods, and so real code will be using
the dictionary.
The introduction in 2.4 of those methods was a mistake for the same reason:
code that previously saw all (urllib2 user)-provided headers in .headers
now sees only a subset (and the function interface is ugly and incomplete).
A better change would have been to replace .headers dict with a dict
subclass (or UserDict.DictMixin instance?) that preserved the .headers
interface and also provided access to the "unredirected" headers. It's
probably too late to fix that, though.
Check .capitalize() case normalization:
>>> url = "http://example.com"
>>> Request(url, headers={"Spam-eggs": "blah"}).headers["Spam-eggs"]
'blah'
>>> Request(url, headers={"spam-EggS": "blah"}).headers["Spam-eggs"]
'blah'
Currently, Request(url, "Spam-eggs").headers["Spam-Eggs"] raises KeyError,
but that could be changed in future.
"""
def test_request_headers_methods():
"""
Note the case normalization of header names here, to .capitalize()-case.
This should be preserved for backwards-compatibility. (In the HTTP case,
normalization to .title()-case is done by urllib2 before sending headers to
http.client).
>>> url = "http://example.com"
>>> r = Request(url, headers={"Spam-eggs": "blah"})
>>> r.has_header("Spam-eggs")
True

[('Spam-eggs', 'blah')]
>>> r.add_header("Foo-Bar", "baz")
>>> items = sorted(r.header_items())
>>> items
[('Foo-bar', 'baz'), ('Spam-eggs', 'blah')]
Note that e.g. r.has_header("spam-EggS") is currently False, and
r.get_header("spam-EggS") returns None, but that could be changed in
future.
