rfc6266-parser

This module parses and generates HTTP ``Content-Disposition`` headers.
These headers are used when getting resources for download;
they provide a hint of whether the file should be downloaded,
and of what filename to use when saving.

difference rfc6266

This module is a fork of rfc6266 which includes the latest bugfix 'NullHandler should be an instance, not a class' and bumped the version to 0.0.5.

Usage

Receiver
--------

``parse_headers`` builds a ``ContentDisposition`` object from the
``Content-Disposition`` header and (as a fallback) the document
location. Shortcuts work with response objects from httplib2
and the requests library.

Important attributes of ``ContentDisposition`` are ``is_inline``,
``filename_unsafe``, ``filename_sanitized``.

Sender
------

``build_header`` builds a header value from a filename.

Security

The Content-Disposition filename should be used with caution. Do not let the sender overwrite an arbitrary filesystem location, pick arbitrary extensions or filenames with special meaning, pick filenames containing unusual or misleading characters, etc. Read RFC 6266 section 4.3 for more details.

Testing

To test in the current Python implementation::

    py.test

To test compatibility across Python releases::

    tox


rfc6266 is currently tested under Python 2.7, Python 2.6,
Python 3.3, Python 3.4, Python 3.5, Python 3.6 and PyPy (1.7), PyPy(5.10.0) for Python3.
