werkzeug.Headers.getlist

Headers.getlist(key, type=None, as_bytes=False)[source]

Return the list of items for a given key. If that key is not in the Headers, the return value will be an empty list. Just as get() getlist() accepts a type parameter. All items will be converted with the callable defined there.

New in version 0.9: Added support for as_bytes.

Parameters:
  • key – The key to be looked up.
  • type – A callable that is used to cast the value in the Headers. If a ValueError is raised by this callable the value will be removed from the list.
  • as_bytes – return bytes instead of unicode strings.
Returns:

a list of all the values for the key.
