Package: notrequests
A Python wrapper for the built-in urllib2 module. The API is compatible with [the excellent Requests library][requests], but omitting features such as sessions and support for keep-alive.Notrequests is intended for doing HTTP requests on [Google App Engine][gae] where Requests has some disadvantages.It is not Python 3 compatible (yet).InstallationFrom PyPI:$ pip install notrequestsOr download and run setup as normal:$ curl -L -o notrequests.ziphttps://github.com/davidwtbuxton/notrequests/archive/master.zip$ unzip notrequests.zip
$ cd notrequests-master
$ python setup.py installUsage### Basic usageNotrequests is compatible with the Requests API (or it tries to be).>>> import notrequests
>>>
>>> response = notrequests.get('http://httpbin.org/get')
>>> response.status_code == notrequests.codes.ok
TrueBut it doesn’t do everything that Requests does. There’s no session support, no keep-alive support and it reads the entire response into memory.The response body is available as a byte string or as unicode.>>> response = notrequests.get('http://httpbin.org/encoding/utf8')
>>> response.headers['content-type']
'text/html; charset=utf-8'
>>> type(response.content)
<type 'str'>
>>> type(response.text)
<type 'unicode'>Decoding to unicode relies on the server having sent a valid content-type header. This is different to Requests because Requests has smarts to sniff the encoding should the response not include a content-type header.Notrequests uses urllib2 but behaves more like Requests. So it won’t throw an exception on 4xx and 5xx responses.>>> response = notrequests.get('http://httpbin.org/status/404')
>>> response.status_code == notrequests.codes.not_found
TrueYou can also test for failure, or raise an exception.>>> response = notrequests.get('http://httpbin.org/status/200')
>>> response.ok
True
>>> response.raise_for_status()
>>> response = notrequests.get('http://httpbin.org/status/404')
>>> response.ok
False
>>> response.raise_for_status()
Traceback (most recent call last):
  ...
notrequests.HTTPError: Error 404 for http://httpbin.org/status/404### RedirectsIf you want to prevent Notrequests following a redirect response, you can use theallow_redirectskeyword:>>> url = 'http://httpbin.org/redirect/1'
>>> response = notrequests.get(url)
>>> response.status_code
200
>>> response = notrequests.get(url, allow_redirects=False)
>>> response.status_code
302On Google App Engine, theX-Appengine-Inbound-Appidheader will only be set if [the sending application doesn’t allow redirects!][appidentity]### AuthenticationYou can do basic auth just like Requests (but not other authentication types):>>> url = 'http://httpbin.org/basic-auth/alice/secret'
>>> response = notrequests.get(url)
>>> response.status_code
401
>>> response = notrequests.get(url, auth=('alice', 'secret'))
>>> response.status_code
200### JSONAnd send and decode JSON:>>> import pprint
>>> response = notrequests.put('http://httpbin.org/put', json={'foo': ['bar', 'baz']})
>>> data = response.json()
>>> pprint.pprint(data)
{u'args': {},
 u'data': u'{"foo": ["bar", "baz"]}',
 u'files': {},
 u'form': {},
 u'headers': {u'Accept-Encoding': u'identity',
              u'Content-Length': u'23',
              u'Content-Type': u'application/json',
              u'Host': u'httpbin.org',
              u'User-Agent': u'notrequests/0.1'},
 u'json': {u'foo': [u'bar', u'baz']},
 u'origin': u'10.10.10.1',
 u'url': u'http://httpbin.org/put'}### Accessing link headersIf the server sent ‘Link’ headers in the response (often used by APIs to give links to the next page of results) then you can get the parsed links straight from the response object:>>> response.headers['Link']
'<https://example.com/?page=2>; rel="next"'
>>> response.links['next']['url']
'https://example.com/?page=2'### Uploading filesThere’s also support for uploading files:>>> import io
>>> fileobj = io.BytesIO('foo bar baz')
>>> response = notrequests.post('http://httpbin.org/post', files={'upload': fileobj})
>>> response.json()['files']
{u'upload': 'foo bar baz'}As with Requests, the keys in the files dict are the form field input names and
the values in the files dict can be a 2-tuple of file name with file object or
byte string:>>> files = {'upload': ('my-file.txt', b'Foo\nbar\nbaz.')}
>>> response = notrequests.post('http://httpbin.org/post', files=files)
>>> print response.request.data

The default isverify=True, so Notrequests will raisessl.CertificateErrorif the certificate does not match the server’s hostname.>>> response = notrequests.get('https://swupdl.adobe.com', verify=False)Notrequests does not support specifying alternate CA bundles.API compatibilityThese are some features of [the Requests API][api] that Notrequests has _not_ implemented. It isn’t a complete list, and it would be nice to have better support.SessionsResponse.historyStreaming uploads / downloads and iterating over dataAlternate names for status codesProxiesTestsRun the tests with [tox][tox].By default the tests make requests tohttp://httpbin.org, but you can run a local instance which will speed things up.$ pip install httpbin gunicorn
$ gunicorn –bind 127.0.0.1:8888 httpbin:app
$ export NOTREQUESTS_TEST_URL=”http://127.0.0.1:8888”
$ toxWhy not use Requests?Google App Engine patches httplib in the standard library to use its urlfetch service, and restricts [the sockets API][sockets] to paid applications. Requests does not use httplib and uses sockets.If you want to use [the app identity service to authenticate connections between App Engine applications][appidentity] you have to use the urlfetch service, you cannot use Requests. Notrequests works because it uses urllib2, which uses httplib.[requests]:http://www.python-requests.org/[gae]:https://cloud.google.com/appengine/[tox]:http://codespeak.net/tox/[appidentity]:https://cloud.google.com/appengine/docs/python/appidentity/#Python_Asserting_identity_to_other_App_Engine_apps[sockets]:https://cloud.google.com/appengine/docs/python/sockets/[api]:http://requests.readthedocs.org/en/latest/api/
