"""
|
|
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
|
|
httplib).
|
|
|
|
>>> url = "http://example.com"
|
|
>>> r = Request(url, headers={"Spam-eggs": "blah"})
|
|
>>> r.has_header("Spam-eggs")
|
|
True

[('Spam-eggs', 'blah')]

>>> items = r.header_items()
|
|
>>> items.sort()
|
|
>>> 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.
