Is there a working OAuth library for Python 3? - python

What's the most current form of Oauth for Python 3?
I'm trying to create a stock screener using my broker's API, which uses Oauth. Most of the info I find is out of date or conflicting. I've seen the following modules referenced:
Oauth - Seems to be the original, now outdated. I get an error of "'module' object has no attribute 'Consumer'"
Oauth2 - Newer version, apparently also outdated? The one most referenced one online. Glitches out in pip/can't figure out how to install it.
Oauthlib - IIRC, claims to be the new replacement for Oauth and Oauth2
Rauth.OAuth2Service - Also potentially replacement for Oauth and Oauth2?
Requests - ?
Oauth_hook - ?
pyoauth2 - I get an error about not having a module named "client" in pyoauth2's init.
None of them seem to work as expected, and I have a feeling that this is due to low Oauth 3 support. Have you gotten OAuth to work in Python 3? If so, how did you do it?

It looks like Requets_oauthlib works. Here's code I used that works in Python 3. I'm posting it because most of the example code I found used formats that I couldn't get working.
from requests_oauthlib import OAuth1
client_key = ''
client_secret = ''
resource_owner_key = ''
resource_owner_secret = ''
def query(queryurl):
headeroauth = OAuth1(client_key, client_secret, resource_owner_key,
resource_owner_secret, signature_type = 'auth_header')
return requests.get(queryurl, auth = headeroauth)
query('http://website.com')

Author of rauth here: rauth is a client library which currently does not officially support Python 3.
However, we are working on it, and there's an active branch (aptly named "python-3") over at GitHub which works. You're free to use it, but bear in mind that things may change slightly when we officially release support for it later on. With that said, it would be great to have people out in the real world testing it so that we can make changes to accommodate the Python 3 ecosystem.
Also note: oauthlib is not a replacement for rauth and not a client library. It attempts to be a generic solution, much like python-oauth2 was, but it doesn't provide a client, unlike python-oauth2.

KeyError: u'x-rate-limit-limit'

I'm trying to use the Uber API in Python but I can't even get the basic commands to work. I'm following the code suggested on the GitHub page (https://github.com/uber/rides-python-sdk).
from uber_rides.session import Session
session = Session(server_token='xxxxxx')
from uber_rides.client import UberRidesClient
client = UberRidesClient(session)
response = client.get_products(37.77, -122.41)
products = response.json.get('products')
When I run this I get the following error - KeyError: u'x-rate-limit-limit'
I did make a developer account with Uber and I've tried using different Server Tokens, but none of them work.
Can anyone help?
You are experiencing an issue that was resolved with the latest SDK fix (GitHub issue). This has happened because the Python SDK was upgraded to use the v1.2 endpoints of the Uber API. However, with the upgrade to v1.2 Uber also deprecated the rate limiting headers (X-Rate-Limit-Limit, X-Rate-Limit-Remaining, X-Rate-Limit-Reset). The older SDK version is still using them. That's what causing you trouble.
In order to resolve your issue, please install the newest SDK version (> 0.2.7.1).
You are getting rate limited. This means you are sending requests so frequently that Uber believes you are doing it maliciously. As Uber advises, you should "spread out your requests," by using time.sleep() for example.

How do I connect to quickbooks online via python?

I'm trying to figure out how to authenticate and create an entry on quickbooks online through Python. Currently, when I try to click auth link in their API Explorer, I get 404 page.
What I'm trying to do is creating invoice through Python. However, it seems like their documentation is not complete. I contacted their support, and I haven't heard from them yet.
The python-quickbooks library is probably the correct choice now, as it is a "complete rework of quickbooks-python". It has pretty comprehensive instructions on getting and using the auth keys, though I wouldn't call it "simple", since the process is by definition somewhat complex. The instructions are "for Django", but the Django-specific code simply gets parameters out of a URL string.
We're using it to great effect, because the syntax is as easy as:
auth_client = AuthClient(
client_id = CLIENT_ID # from QB website
,client_secret = CLIENT_SECRET # from QB website
,environment = 'sandbox' # or 'production'
,redirect_uri = REDIRECT_URI
)
client = QuickBooks(
auth_client = auth_client
,refresh_token = REFRESH_TOKEN
,company_id = COMPANY_ID
)
account = Account.get(qbid, qb=client) # qbid can be retrieved from the AccountList
return account.CurrentBalance
This library will get the job done https://github.com/HaPsantran/quickbooks-python
It works in JSON so you would construct the Invoice based off of docs at https://developer.intuit.com/docs/0025_quickbooksapi/0050_data_services/030_entity_services_reference/invoice using the JSON examples.
The library doesn't support sandbox mode** so if you are going to use the development consumer key and secret than you would change this code.
base_url_v3 = "https://quickbooks.api.intuit.com/v3"
to
base_url_v3 = "https://sandbox-quickbooks.api.intuit.com/v3"
while in that mode.
** Sandbox mode only applies currently to U.S. QBO
Having written a lot of the module #Minimul mentions — with a very helpful start by simonv3, who figured out how to get it working first and then I just built on it — I am fairly confident that this will not support the oauth workflow of getting the request token, prompting the user to authenticate out of band, and then getting and storing the access token. It presumes you already have an access token.
Simon (or another Python developer) may be able to comment on how he gets the access token with Python, and if so, it'd be great if he (or they) could add it to the module for all to enjoy.
I had this same problem. I just figured it out and posed the step-by-step process here:
python with Quickbooks Online API v3
Hope this helps.
I looked at the existing python clients for quickbooks and found them to be either outdated or not having all the features. So i created a new python client for quickbooks which can be found at https://pypi.python.org/pypi/quickbooks-py

How to use OAuth2Credentials with Google API gdata client in python?

I've worked out how OAuth2 works (via https://developers.google.com/api-client-library/python/guide/aaa_oauth) and now have an OAuth2Credentials object (let's call the object credentials) that I want to use for Google Apps provisioning purposes (the example here is using sites, but could be any of the gdata apis)
If I try:
client = gdata.sites.client.SitesClient(site="test-site",domain='my.domain')
client = credentials.authorize(client)
I get
TypeError: new_request() got an unexpected keyword argument 'http_request'
when I try to do anything
If I try
client = gdata.sites.client.SitesClient(site="test-site",domain='my.domain', auth_token=credentials)
or
client = gdata.sites.client.SitesClient(site="test-site",domain='my.domain', auth_token=credentials.access_token)
I get an AttributeError that the relevant object (credentials or credentials.access_token) has no attribute 'modify_request'
Any ideas what I can try?
I'm not entirely sure about Google's client code, but you could always try (shameless plug) sanction. It's an OAuth 2.0 client I wrote a while ago available on Github and PyPI.
The upsides:
Being a whopping 55 LOC, it's tremendously easy to grok. If something goes wrong, you won't have to ask questions here.. You should be able to just understand what's going on ;)
It has been tested with 8 different providers (including Google)
The downsides:
Obviously would require a refactor of your current code
Doesn't assume (and therefore provide) persistence implementations
Doesn't provide API implementations (you have to have a basic understanding of the OAuth 2.0-exposed API that you're dealing with)
This answer says you have to monkeypatch the OAuth2Credentials object, before passing it to the SitesClient(auth_token=credentials). It has an answer showing you how to do the monkey patching

Suds ignoring cache setting?

I'm using suds 0.3.8, Python 2.4.3, and Django 1.1.1. The code I inherited has a long duration for the cached files, but it's expiring on the default cadence of once every 24 hours. The external servers hosting the schemas are spotty, so the site is going down nightly and I'm at the end of my rope.
Any idea what is jacked up in this code?
imp = Import('http://domain2.com/url')
imp.filter.add('http://domain3.com/url')
imp.filter.add('http://domain4.com/url')
imp.filter.add('http://domain5.com/url')
d = ImportDoctor(imp)
url = "http://domain.com/wsdl"
client = Client(url, doctor=d, timeout=30)
clientcache = client.options.cache
clientcache.setduration(days=360)
Answering my own question:
This ended up not being a version issue, but user error. Unfortunately the suds documentation isn't as clear as it could be. Reading it, one would think the code above would work, but (on suds v0.39+) it should be written as:
imp = Import('http://domain2.com/url')
imp.filter.add('http://domain3.com/url')
imp.filter.add('http://domain4.com/url')
imp.filter.add('http://domain5.com/url')
d = ImportDoctor(imp)
oc = ObjectCache()
oc.setduration(days=360)
url = "http://domain.com/wsdl"
client = Client(url, doctor=d, cache=oc, timeout=30)
Looking at it now, it makes complete sense that the cache has to be configured before the Client is initialized.
Hopefully this will help anyone else trying to set a suds cache, and it seems to be ignoring your settings.
The problem may be a lack of proper support in the default cache type in the Suds 0.3.8, or possibly even a bug in this version. If you're able to upgrade to Suds 0.3.9 or later (latest is 0.4), that would allow this behavior to work as expected.

How to access YQL in Python (Django)?

Hey, I need a simple example for the following task:
Send a query to YQL and receive a response
I am accessing public data from python backend of my Django app.
If I just copy/paste an example from YQL, it says "Please provide valid credentials".
I guess, I need OAuth authorization to do it.
So I got an API key and a shared secret.
Now, what should I do with them?
Should I use python oauth library? This one?
http://oauth.googlecode.com/svn/code/python/oauth/
But what is the code? How I pass my secret/API key along with my yql query?
I guess, many Django programmers would love to know this.
I've just released python-yql also available on pypi. It can do public, two-legged oauth a.k.a signed requests and facilitate 3-legged outh too.
It's brand new so there may be some bugs whilst I work on improving the test coverage but should hopefully do what you need. See the source for some idea on how to use it.
Installing to try it is as follows:
sudo easy_install yql
Bug/Feature requests can be filed here: https://bugs.launchpad.net/python-yql
If you only are accessing public data you can just make a direct rest call from python.
>>> import urllib2
>>> result = urllib2.urlopen("http://query.yahooapis.com/v1/public/yql?q=select%20title%2Cabstract%20from%20search.web%20where%20query%3D%22paul%20tarjan%22&format=json").read()
>>> print result[:100]
{"query":{"count":"10","created":"2009-11-03T04:47:01Z","lang":"en-US","updated":"2009-11-03T04:47:0
And then you can parse the result with simplejson.
>>> import simplejson
>>> data = simplejson.loads(result)
>>> data['query']['results']['result'][0]['title']

Ok, I sort of resolved the problem.
In YQL console example for data/html the following url was presented as an example:
http://query.yahooapis.com/v1/yql?q=select+*+from+html+where+url%3D%22http%3A%2F%2Ffinance.yahoo.com%2Fq%3Fs%3Dyhoo%22+and%0A++++++xpath%3D%27%2F%2Fdiv%5B%40id%3D%22yfi_headlines%22%5D%2Fdiv%5B2%5D%2Ful%2Fli%2Fa%27
It does not work!
But if you insert "/public" after "v1/" than it magically starts working!
http://query.yahooapis.com/v1/public/yql?q=select+*+from+html+where+url%3D%22http%3A%2F%2Ffinance.yahoo.com%2Fq%3Fs%3Dyhoo%22+and%0A++++++xpath%3D%27%2F%2Fdiv%5B%40id%3D%22yfi_headlines%22%5D%2Fdiv%5B2%5D%2Ful%2Fli%2Fa%27
But the question of how to pass my API key (for v1/yql access) is still open. Any advice?
