httpio
======
HTTP resources as random-access file-like objects
httpio is a small Python library that allows you to access files
served over HTTP as file-like_ objects (which is to say that they
support the interface of the standard library's BufferedIOBase_
class). It differs from libraries like ``urllib`` and ``requests`` in
that it supports ``seek()`` (which moves an internal pointer), and
that ``read()`` makes a request with the ``Range`` header set. It also
supports caching of contents using a configurable block size, and will
reuse TCP connections where possible.
Installation
------------
Use ``pip`` to install httpio:
.. code-block:: console
$ pip install httpio
Usage
-----
.. code-block:: python
import zipfile
import httpio
url = "http://some/large/file.zip"
with httpio.open(url) as fp:
zf = zipfile.ZipFile(fp)
print(zf.namelist())

.. _BufferedIOBase: https://docs.python.org/3/library/io.html#io.BufferedIOBase
Unit Tests
----------
Unit tests are provided for the standard behaviours implemented by
the library. They can be run with
.. code-block:: console
$ python -m unittest discover -s tests
or a ``tox.ini`` file is provided which allows the tests to be run in
virtual environments using the ``tox`` tool:
.. code-block:: console
$ tox
