Metadata-Version: 1.0
Name: restkit
Version: 4.1.3
Summary: Python REST kit
Home-page: http://benoitc.github.com/restkit
Author: Benoit Chesneau
Author-email: benoitc@e-engura.org
License: MIT
Description: About
-----
Restkit is an HTTP resource kit for `Python <http://python.org>`_. It allows you to easily access to HTTP resource and build objects around it. It's the base of `couchdbkit <http://www.couchdbkit.org>`_ a Python `CouchDB <http://couchdb.org>`_ framework.
Restkit is a full HTTP client using pure socket calls and its own HTTP parser. It's not based on httplib or urllib2.
Installation
------------
Restkit requires Python 2.x superior to 2.5 and http-parser 0.5.3 or
sup.
To install restkit using pip you must make sure you have a
recent version of distribute installed::
$ curl -O http://python-distribute.org/distribute_setup.py
$ sudo python distribute_setup.py
$ easy_install pip
To install or upgrade to the latest released version of restkit::
$ pip install http-parser
$ pip install restkit
Note: if you get an error on MacOSX try to install with the following
arguments::
$ env ARCHFLAGS="-arch i386 -arch x86_64" pip install http-parser
Usage
=====
Perform HTTP call support with `restkit.request`.
++++++++++++++++++++++++++++++++++++++++++++++++++
Usage example, get friendpaste page::
from restkit import request
resp = request('http://friendpaste.com')
print resp.body_string()
print resp.status_int
Create a simple Twitter Search resource
+++++++++++++++++++++++++++++++++++++++
Building a resource object is easy using `restkit.Resource` class.
We use `simplejson <http://code.google.com/p/simplejson/>`_ to
handle deserialisation of data.
Here is the snippet::
from restkit import Resource
try:
import simplejson as json
except ImportError:
import json # py2.6 only
class TwitterSearch(Resource):
def __init__(self, pool_instance=None, **kwargs):
search_url = "http://search.twitter.com"
super(TwitterSearch, self).__init__(search_url, follow_redirect=True,
max_follow_redirect=10,
pool_instance=pool_instance,
**kwargs)
def search(self, query):
return self.get('search.json', q=query)
def request(self, *args, **kwargs):
resp = super(TwitterSearch, self).request(*args, **kwargs)
return json.loads(resp.body_string())
if __name__ == "__main__":
s = TwitterSearch()
print s.search("gunicorn")
Reuses connections
------------------
Reusing connections is good. Restkit can maintain for you the http connections and
reuse them if the server allows it. To do that you can pass to any object a pool
instance inheriting `reskit.pool.PoolInterface`. By default a threadsafe pool is
used in any application:
::
from restkit import *
from socketpool import ConnectionPool
# set a pool
pool = ConnectionPool(factory=Connection, max_size=10)
# do the connection
res = Resource('http://friendpaste.com', pool=pool)
or if you use `Gevent <http://gevent.org>`_:
::
from restkit import *
from socketpool import ConnectionPool
# set a pool
pool = ConnectionPool(factory=Connection, backend="gevent",
max_size=10)
# do the connection
res = Resource('http://friendpaste.com', pool=pool)
Authentication
==============
Restkit support for now `basic authentication`_ and `OAuth`_. But any
other authentication schema can easily be added using http filters.
Basic authentication
++++++++++++++++++++
To use `basic authentication` in a `Resource object` you can do::
from restkit import Resource, BasicAuth
auth = BasicAuth("username", "password")
r = Resource("http://friendpaste.com", filters=[auth])
Or simply use an authentication url::
r = Resource("http://username:password@friendpaste.com")
.. _basic authentification: http://www.ietf.org/rfc/rfc2617.txt
.. _OAuth: http://oauth.net/
OAuth
+++++
Restkit OAuth is based on `simplegeo python-oauth2 module <http://github.com/simplegeo/python-oauth2>`_ So you don't need other installation to use OAuth (you can also simply use `restkit.oauth2` module in your applications).
The OAuth filter `restkit.oauth2.filter.OAuthFilter` allow you to associate a consumer per resource (path). Initalize Oauth filter with::
path, consumer, token, signaturemethod
`token` and `method signature` are optionnals. Consumer should be an instance of `restkit.oauth2.Consumer`, token an instance of `restkit.oauth2.Token` signature method an instance of `oauth2.SignatureMethod` (`restkit.oauth2.Token` is only needed for three-legged requests.
The filter is appleid if the path match. It allows you to maintain different authorization per path. A wildcard at the indicate to the filter to match all path behind.
Example the rule `/some/resource/*` will match `/some/resource/other` and `/some/resource/other2`, while the rule `/some/resource` will only match the path `/some/resource`.
Simple client example:
~~~~~~~~~~~~~~~~~~~~~~
::
from restkit import OAuthFilter, request
import restkit.oauth2 as oauth
# Create your consumer with the proper key/secret.
consumer = oauth.Consumer(key="your-twitter-consumer-key",
secret="your-twitter-consumer-secret")
# Request token URL for Twitter.
request_token_url = "http://twitter.com/oauth/request_token"
# Create our filter.
auth = oauth.OAuthFilter('*', consumer)
# The request.
resp = request(request_token_url, filters=[auth])
print resp.body_string()
If you want to add OAuth to your `TwitterSearch` resource::
# Create your consumer with the proper key/secret.
consumer = oauth.Consumer(key="your-twitter-consumer-key",
secret="your-twitter-consumer-secret")
# Create our filter.
client = oauth.OAuthfilter('*', consumer)
s = TwitterSearch(filters=[client])
