ietfparse.constants¶

This module contains some useful constant values for using alongside ietfparse.datastructures.ContentType instances or as parameters to the ietfparse.algorithms.select_content_type function. These are cherry-picked from the IANA Media Types registry.

`ietfparse.constants` ¶

Useful constant values.

Warning

Take care when comparing content type values since equality comparison includes comparing parameter values. The ietfparse.algorithms.select_content_type algorithm should be used to select content type based on the Accept header.

>>> from ietfparse import headers
>>> a = headers.parse_content_type('application/json')
>>> b = headers.parse_content_type('application/json; charset=utf-8')
>>> c = headers.parse_content_type('application/json; charset="UTF-8"')
>>> a == b
False
>>> a == c
False
>>> b == c
True

The last example shows that parameters are normalized when parsing.
