Foursquare strategy for OmniAuth

OmniAuth Foursquare

This gem contains the Foursquare strategy for OmniAuth.

Foursquare uses the OAuth2 flow, you can read about it here: https://developer.foursquare.com/docs/oauth.html

How To Use It

So let's say you're using Rails, you need to add the strategy to your Gemfile:

gem 'omniauth-foursquare'

You can pull them in directly from github e.g.:

gem 'omniauth-foursquare', :git => 'https://github.com/arunagw/omniauth-foursquare.git'

Once these are in, you need to add the following to your config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :foursquare, "consumer_key", "consumer_secret"
end

You will obviously have to put in your key and secret, which you get when you register your app with Foursquare (they call them API Key and Secret Key).

Now just follow the README at: https://github.com/intridea/omniauth

Supported Rubies

OmniAuth Foursquare is tested under 1.8.7, 1.9.2, 1.9.3, 2.x and Ruby Enterprise Edition.

omniauth-foursquare's Issues

Feature Request: add display options to client_params

Hi!

It would be nice if the gem can support the :display parameter in the client params method, now i have my omniauth-foursquare gem patched in this way:

def client_params
{:client_id => options[:client_id], :redirect_uri => callback_url ,:response_type => "code", :display => options[:display]}
end

The :display is set in the omniauth initializer as :display => 'webpopup' and work great for me.

Thanks for the gem!

ssl error

Hi.
Recently, i update omniauth version. And, I started to use omniauth-foursquare.

mypage can

1. get /auth/foursquare
2. and redirect foursquare authorization page.
3. if I select allow, redirect mypage.

=> next, I have looked this error.

Faraday::Error::ConnectionFailed (SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed)

How can I solve this error?

• I have tried such article(add client_options) but , not work.
  • http://stackoverflow.com/questions/3977303/omniauth-facebook-certificate-verify-failed
• everyone writes, update ruby in rvm and reinstall openssl in rvm, but i don't use rvm
• environment is
  • CentOS release 5.6 (Final)
  • ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux] it is not rvm. native install
  • 'rails', '3.1.3'
• I have used old omniauth version 0.3.0, and I can login foursquare.if I update this version, It doesnot work.

omniauth-foursquare isn't compliant with the auth hash schema

Based upon the omniauth wiki -
https://github.com/intridea/omniauth/wiki/Auth-Hash-Schema

The image should be "A URL representing a profile image of the authenticating user. Where possible, should be specified to a square, roughly 50x50 pixel image.", however in case on omniauth-foursquare it's a hash.

In my projects I do something like this in order to normalize it (50x50 was proven to be to small for me):

image =  [image['prefix'], '100x100', image['suffix']].join

I think that it's a sensible approach to return a URL for info.image, and put this has in the 'extra' hash (if it's not there already).

omniauth fails to accept callbacks directly from foursquare

callbacks currently must be initiated through omniauth and pass a state paramater to foursquare to authenticate. However with the connected apps platform, users have the ability to add the app without visiting the app's site first.

This causes the callback to fail because omniauth did not make the first call in the sequence.

Foursquare API now require a version params

Hi!
I've got this error on the callback_phase

<OAuth2::Error: :
{"meta":{"code":410,"errorType":"param_error","errorDetail":"The Foursquare API no longer supports requests that do not pass in a version parameter. For more details see https://developer.foursquare.com/overview/versioning"},"response":{}}>

In the Foursquare docs is reported that all requests require a v=YYYYMMDD parameter from date 28-01-2014.

https://developer.foursquare.com/overview/versioning

I will try to make a pull request for this, but I don't have eneugh time at this moment ...

Feature Request: Example use with Devise

Do you have this gem working with devise? I am trying to use the omniauth support with devise, but I am having trouble with the OmniauthCallbacksController.

Csrf detected

Hi there,
I've spent a number of hours researching this before deciding to ask here.
Upon signing in, I keep being bounced to my app (/users/sign_in#=) with the following error:
Could not authenticate you from Foursquare because "Csrf detected"

Any insights?

This is what I see last in the console:

• I, [2014-10-19T19:43:38.947771 #2] INFO -- omniauth: (foursquare) Request phase initiated.

Thanks!
