Does it work? I tried to do some OAuth in Python a couple of years back and it was a total disaster; four competing libraries, none of which worked. But that was a long time ago and I don't think this Rauth library even existed when I last looked.

llambda5• 13 years ago

Maybe you should try it?

sandyarmstrong• 13 years ago

Yes.

trtg2• 13 years ago

Yes it definitely works and does so more easily than any alternative I've tried. I've used it to interface quickly to something like 20 different APIs at this point.

Just in case anyone is confused, this is a library for client-side OAuth. That said, it's great for quick test scripts — it made my life a lot easier when I was working on a provider implementation.

EDIT: Although their README only shows an OAuth1 example, check out https://github.com/litl/rauth/blob/master/examples/github-cl... for an example of using it with an OAuth2 provider.

So I guess that's the open part.

zalew3• 13 years ago

to be honest I am currently lost on the state of oauth in python, has sth changed since this post http://pydanny.com/the-sorry-state-of-python-oauth-providers...? as OP is a client lib, could somebody with practical experience tell me what's the current best library for setting up an oauth provider? bonus question: should I bother with 2.0 or stick to 1.0 (3rd party apps and mobile) http://hueniverse.com/2012/07/oauth-2-0-and-the-road-to-hell... ?

peter_l_downs2• 13 years ago

Not much has changed. I'm currently working to open source an implementation I worked on that's compliant with the finalized version of the spec. The most up-to-date implementation I've seen in the open is https://github.com/hiidef/oauth2app, which implements draft 16.

zalew3• 13 years ago

thanks, looks sane.

marquis3• 13 years ago

https://github.com/hasgeek/lastuser was the least painless method in my experience but I never tried any non-lastuser clients with it so I can't comment on library compatibility.

zalew3• 13 years ago

it doesn't have any docs and even from the page I have no idea what it actually does, it doesn't look like an oauth provider (?)

If you're looking for a more full stack framework in python, tornado has had support for oauth since it's release. It's implementation does rely on the tornado ioloop though, so it's not something you can easily just pull and use elsewhere.

dtwwtd2• 13 years ago

It's really easy to use too. I recently extended the base implementation for a service that it didn't support and it took me very little time.

jrussbowman2• 13 years ago

I put some time into it a couple years ago before my 2nd kid was born. I've always wanted to go back and work on making it a bit easier to use. One of the things I'd love to do is get rid of it being so tied to request handlers so you can use it more seamlessly in apps.

This is the underlying problem: OAuth implementations that are coupled to other pieces of technology not strictly related to OAuth. So then we keep reimplementing the same protocol over and over again.

idan4• 13 years ago

I wish the author had contributed to existing efforts (https://github.com/idan/oauthlib) instead of rolling yet another OAuth implementation. We set out to build a robust, comprehensive, spec-complete OAuth signing logic library a year ago, and today it delivers what it says on the tin, thanks to a lot of work and a raft of dedicated contributors. We have support for all of the OAuth1 spec, and we're working towards OAuth2. The idea is to have one de-facto reference OAuth implementation for python instead of a few confusingly different choices, because the differences are really hard to spot for anybody who hasn't spent some time cuddling up with the RFC.

Doing OAuth signing logic correctly is pretty finicky. Requests is great, and we provide a shim layer for it, but it's silly to reimplement the underlying request signing logic for requests, urllib3 or what-have-you. And what happens when you need a server-side implementation for verifying signatures? It makes more sense to do the tricky logic in a separate, testable library than tying it to one representation of an HTTP request.

Having said all this, anybody willing to wade into this mess and write something is my kind of crazy. Respect.

Look at the examples and docs on the oauthlib library. It's like Java. SkeletonValidator(RequestValidator) ??? This is totally the opposite of pragmatism, and one of the main reasons I've moved away from Python and build most things in Ruby now.

After doing Django for 5 years, the nail in the coffin was when I wanted to simply access a users me object from their facebook graph timeline. Riddle me that. In ruby-pragmatism land it's a gem and a line or two of code away, thanks to the awesome Koala library.

Kenneth Reitz's recent requests library is the first refreshing and pragmatic python tool I have seen in a long time. This oauth library shares the same friendly and straightforward interface too. The docs and examples are directly clear and directly in front of you. It's simple and pragmatic.

The stars on the repo's speak for themselves ... rauth has over 700 stars, whereas oauthlib has considerably less than half of that. I'm not trying to tell you that you suck, because I admire your work quite a lot, but I think these days developers want simple and pragmatic.

pekk3• 13 years ago

This entire complaint would go away with a thin 'for humans' wrapper on top. If you look inside requests and its dependencies you will see some complexities too, they are just hidden from you. But this does not mean that it makes sense to write the low-level stuff in a way that prevents reuse - though that reusability might look abstract - this is the reason we are swimming in OAuth implementations.

idan4• 13 years ago

In one breath, you're complaining about a library's complexity in abstracting away an underlying mess, and in the next, you're praising a library that is complex and abstracts away some underlying mess.

It's not about stars. It's about the right architectural choice. Believe me when I say that we thought long and hard about the structure of OAuthLib, and it looks nothing at all like Java. When we started out, we were reacting to the mess that is/was python-oauth[2] and its class-based ridiculous. Like all real-world projects, after spending time with the spec and refactoring the parts which were common to the various signing flows, you end up with some real-world ugly.

First, I believe rauth existed prior to your library: rauth is over a year old now. (Or maybe existed at around the same time; regardless as you'll see below, contributing to your project wouldn't have made sense for us.)

Second, you're trying to solve a different problem than rauth solves: we needed a library that provided for the practical, de facto implementation of OAuth 1.0/a and 2.0 as well as Ofly which allowed us to consume provider APIs. This is exactly what rauth does. It loosely wraps Requests, which means you get to basically use Requests that also happens to handle real-world OAuth providers as a consumer. I don't think it's really fair to call this "silly": it's clearly filled a hole in the ecosystem for some people.

If you want to consume an OAuth provider, rauth tries to give you a simple interface to do so with. It's almost as easy as using Requests. You might even say, it's OAuth for Humans. (Sorry, Kenneth. :)

Edit: to be clear, rauth is about pragmatic simplicity, about a clean API that's pleasant to work with. It's a client for OAuth modeled around the fact and philosophy of Requests. Vis-à-vis everything else I've seen, this is in pretty stark contrast to existing libraries.

trtg2• 13 years ago

Thanks for your work on rauth, I've been using it for a long time and I'm hoping to update my projects to use the latest version to pick up requests 1.x support some time soon.

pekk3• 13 years ago

Is it really necessary to couple to requests in order to have a decent OAuth implementation?

Why not a layered API, with lower levels supporting a higher-level wrapper library using requests?

idan4• 13 years ago

Whoops, didn't notice the chronology.

All the same: OAuthLib and its libraries cover the exact use-case you've laid out, just in a fashion that has some architectural benefits on top of the usability goals. The simple "OAuth for Humans" thing you're reaching for exists—it's https://github.com/requests/requests-oauthlib. Kenneth and I hashed this interface out before we started out on OAuthLib, and thus far it's the only shim library for OAuthLib I know of (though it's pretty simple to write something equivalent which bridges OAuthLib's domain knowledge and any given HTTP request implementation). I even rewrote Requests' underlying auth implementation to make this sort of thing possible. And now you have:

oauth = OAuth1(client_key=key, client_secret=secret) r = requests.post(url=request_token_url, auth=oauth)

I don't see OAuth1 getting simpler than that, and the underlying signing logic is there for anybody to use in any context—as a provider, consumer, in a stubbing library—whatever!

Recently I tried doing cas integration for my django website. A colleague pointed to a Rails gem - install a gem, point to the cas url and, poof, done.

For django, I struggled, and struggled. Found a couple of libraries and a number of forks of these spread across github and bitbucket. Got one, but it didn't work. Debugged the code, fixed some stuff in my own fork, and got it working 5 hours later.

The world of python seems to have lots of half-baked libraries that are dead or dying. Makes you miss Ruby / Rails.

dbgrandi• 13 years ago

I couldn't agree with this more. In Rails, I'm used to using omniauth, and plugging in any number of provider gems that deal with the subtle differences between how Dropbox and LinkedIn and whatever implement OAuth...and having them all hook into whatever Rack based framework I use (Rails, Sinatra, etc)

Rauth is a good start, but without a library that couples it to a full web stack, I'm spending a lot of time hooking it into my flask app and trying to make sure I don't make mistakes managing my session variables, etc.

Perhaps I'll start up a rauth-providers repo to catalog this stuff.

denzil_correa• 13 years ago

Thank You, Thank you! After the state of python-oauth2 this comes as the best oauth library to be used in Python. I however I have one query - how would you handle Oauth three-legged requests? [0] This is important for people who do not necessarily build web apps but collect data from Twitter using Oauth (for a higher API limit).

Does rauth work with Python 3?

llambda5• 13 years ago

Not yet.

Basically the main reason for python-social-auth (https://github.com/omab/python-social-auth) to use oauthlib/requests-oauthlib instead of rauth.

nostromo• 13 years ago

If you'll allow me a shameless plug...

My company (dailycred) wraps ten OAuth 1 & 2 providers, as well as email & password and Mozilla Persona in a single OAuth 2 call.

(We started this project because even just within OAuth 2, providers break spec left and right and OAuth can be a huge headache, so we manage all of those headaches for our customers.)
