werkzeug.parse_accept_header¶

werkzeug.parse_accept_header(value, cls=None)[source]¶

Parses an HTTP Accept-* header. This does not implement a complete valid algorithm but one that supports at least value and quality extraction.

Returns a new Accept object (basically a list of (value, quality) tuples sorted by the quality with some additional accessor methods).

The second parameter can be a subclass of Accept that is created with the parsed values and returned.

Parameters:	value – the accept header string to be parsed. cls – the wrapper class for the return value (can be Accept or a subclass thereof)
Returns:	an instance of cls.
