This enables host_matching to be set properly by the time the constructor adds
the static route, and enables the static route to be properly associated with
the required host.
Previously, you could only enable host_matching once your app was already
instantiated (e.g. app.url_map.host_matching = True), but at that point
the constructor would have already added the static route without host matching
and an associated host, leaving the static route in a broken state.
Fixes#1559.
The example code uses `flash` but doesn't import it. So the code as written doesn't work.
This simply adds `flash` to the list of imports in the sample code.
Also, parse_options_header seems to interpret filename* so we better
test the actual value used in the headers (and since it's valid
in any order, use a set to compare)
This commit implements https://tools.ietf.org/html/rfc2231#section-4 in
order to support sending unicode characters. Tested on both Firefox and
Chromium under Linux.
This adds unidecode as a dependency, which might be relaxed by using
.encode('latin-1', 'ignore') but wouldn't be as useful.
Also, added a test for the correct headers to be added.
Previously, using a filename parameter to send_file with unicode characters, it
failed with the next error since HTTP headers don't allow non latin-1 characters.
