Omniauth with FourSquare issue

UPDATE 2011/05/01: I later carefully read through FourSquare's API document, and found it says:

(Note that the request parameters are not JSON, they are standard HTTP keys and values.) All authentication is via OAuth2, which means that all 开发者_如何学运维requests MUST be https.

Could this be the problem that I don't have a SSL connection in my development machine?

Hi all! I am trying to connect FourSquare via Omniauth, I followed the Railscast toturial below, and change the provider into foursquare. But the return is always "invalid_credentials". I googled around and find that there's a discussion about this on GitHub(links below), but seems no conclusion yet. Anyone has idea what went wrong?

Rails.application.config.middleware.use OmniAuth::Builder do
provider :twitter, "XXXXXXX","XXXXXXX"
provider :foursquare, 'XXXXXXX',
'XXXXXXX'
end

I have a gem which will work with omniauth for foursquare.

try to modify your provider initializer to point to your system's certificate path ("/etc/ssl/certs" on Ubuntu)

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :twitter, "XXXXXXX","XXXXXXX"
    provider :foursquare, 'XXXXXXX', {:client_options => {:ssl => {:ca_path => "/etc/ssl/certs"}}}
end

Your config looks fine, although you probably don't want to share your token/secret keys publicly.

Does the callback url that you used when registering your foursquare oauth consumer match the URL that you're testing with? If you used http://www.foo.com/auth/foursquare/callback when registering your consumer, but are testing on your dev environment (http://localhost:3000/..), you'll see that auth/failure error.
