I am trying to develop a facebook integration to fetch the wall posts using KOALA Gem (1.1.0), and Rails 2.3.8 . I can easily generate user_access_token and page_access_token and able to get data using graph API. But when I am using realtime update I can't get datas which need access token. I can access all public information with KOALA api.
I guess we need to pass access_token(user_access_token or page_access_token). I couldn't find an option to pass access token. I checked the RealTimeUpdate class and found only two arguments app_access_token and app_id, which may not be sufficient to get the protected data like feeds and post
Here am attaching the sample code:
#updates = Koala::Facebook::RealtimeUpdates.new(:app_id => YOUR_APP_ID, :secret => YOUR_APP_SECRET )
=> Koala::Facebook::RealtimeUpdates:0x10331fb88 #graph_api=#, #secret=”81297xxxxxxxxxxx”, #app_access_token=”1779yyyyyyy|xxxxxxx”, #app_id=”1779yyyyy”
and you can see app_access_token and access_token has been set the same.
Then I tried to retrieve the access token as follows but it returns nil.
>> #updates.access_token
=> nil
Kindly advise how do I go forward?
Seems this is a bug in facebook . Please have a look #

I am using the Facebook Graph API in my rails projects, no matter I use oauth2 gem or koala, It need callback_url
Oauth2
token = client.auth_code.get_token('code_value', :redirect_uri => 'http://localhost:8080/oauth/callback')
Koala
#oauth = Koala::Facebook::OAuth.new(app_id, app_secret, callback_url)
I try to use http://localhost:3000/callback in my project, but it's not working.
Should I develop a routes for that?
like: get 'callback' => 'oauth#callback'?
What should I write in the callback method in OauthController, what does it use for? Thanks
Yes, you should.
Basically, OAuth uses callback data to provide tokens for authenticating users.
For example
user clicks on "sign in" (or whatever) link and your app redirects they to the OAuth provider (or open it in the iframe).
user permits to your app to use they profile details
OAuth provider send callback to your app with unique code
app uses that code to get secure access token for API communications
That's just a basic example.
In your case you need to implement controller that will parse callback data.
Here is the code example
#oauth = Koala::Facebook::OAuth.new(api_key, app_secret, callback_url)
=> #<Koala::Facebook::OAuth:0x007fc919d014e0 #app_id=1234567890, #app_secret="FaKeAppSecretKey", #oauth_callback_url="http://localhost:3000/callback">
#oauth.url_for_oauth_code
=> "https://www.facebook.com/dialog/oauth?client_id=893637180663238&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fcallback"
And when you go to https://www.facebook.com/dialog/oauth?client_id=893637180663238&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fcallback FB will redirect you to
http://localhost:3000/callback?code=CODE_FROM_CALLBACK
Then you should use implement controller that uses code to get access token
access_token = #oauth.get_access_token(params[:code])
=> "ACCESS_TOKEN"
#graph = Koala::Facebook::API.new(access_token)
=> #<Koala::Facebook::API:0x007fc91a903ae0 #access_token="ACCESS_TOKEN", #app_secret=nil>
profile = #graph.get_object("me")
=> {"id"=>"4492344324865", "email"=>"my_fake_email_address#gmail.com", "first_name"=>"Roman", "gender"=>"male", "last_name"=>"Sotnikov", "link"=>"https://www.facebook.com/app_scoped_user_id/4492344324865/", "locale"=>"en_US", "name"=>"Roman Sotnikov", "timezone"=>6, "updated_time"=>"2015-05-18T05:19:54+0000", "verified"=>true}
Please check https://github.com/arsduo/koala/wiki/OAuth for additional info.
Callback Url is yours applications url -- a GET route -- you want the third party application to redirect to, after its done its work.
So in your routes.rb file simply create a get route
get 'facebook_graph_callback', to: 'controller_name#action'
#A get route which is connected to a controller action
Usually the third party will give you some sort of information back. Quite often its some sort of code. In your controller action you can use find them in params hash.
I'm trying to retrieve a user's Google account information when a form is submitted. In order to do so, I have to make a GET request to an url. Here's what it says in the YouTube API documentation
To request the currently logged-in user's profile, send a GET request
to the following URL. Note: For this request, you must provide an
authentication token, which enables YouTube to identify the user.
https://gdata.youtube.com/feeds/api/users/default
https://developers.google.com/youtube/2.0/developers_guide_protocol_profiles?hl=en
How do I make it so a custom (or specificall this) GET request happens when the form is submitted, and how do I provide the authentication token? Information that might help: When the form is submitted, it will go to the VideoController's new method.
Also after making the request, how do I access the information? I need to see whether <yt:relationship> is present or not in the given information.
Thanks!
I find HTTParty gem as very useful for working with external APIs in rails.
You can make requests as
response = HTTParty.post("http://www.example.com", :timeout => 5, :body => "my body content", :query => { hash_of_params_here } ,:headers => {'Content-Type' => 'application/json', 'AuthKey' => "your_key_here"})
response object will have 'statuscode', 'headers', 'body' etc (whatever youtube send back in your case). You can access its content using
response.parsed_response
same for get requests too
Please do read more about it for better understanding before getting started.
Sources : Documentation & Tutorial
Yuo can use excon gem to make specific CRUD or only get requests to external resources, for example, it should be something like this:
Excon.post('http://youtube.com', :body => 'token=sjdlsdjasdljsdlasjda')
PS: But seem you not requied the direct gems, tru useing google-api gem, as it described here in the documentation.
I'm trying to set up the linkedin api in a rails 3 app using the linkedin gem. I don't want the user to have to authenticate my app in order for the API to get their info. I only need one piece of their public profile (the headline). So, maybe I should just be using xml or json to pull this off (not exactly sure how to get that with linkedin either).
I have the following in a helper so that I can call linkedin_header() in a loop of users. I only have 'client' as the last line of the following code while debugging. It outputs as expected (#). It seems like I am only a step away from success. How can I access a given users headline? I have tried using "client = client.profile(:url => 'linkedin_user_url')", but that return "Call must be made on behalf of a member".
def linkedin_header(account_user)
user = User.find(account_user)
account = Account.where(:user_id => user, :external_id => 1)
api_key = 'aaaaaaaa'
api_secret = 'bbbbbbbb'
client = LinkedIn::Client.new(api_key, api_secret)
rtoken = client.request_token.token # this returns correctly
rsecret = client.request_token.secret # this returns correctly
client
# client = client.profile(:url => 'linkedin_user_url')
end
So, I guess I have two questions. Is my request (public headline of any user) too simple for the above...should I be using XML or JSON. And, if Im close...can I make the API work for me without the user having to authenticate via linkedin.
Based off of what I read from the LinkedIn API reference (http://developer.linkedin.com/documents/authentication)
You have to make requests to their API only after being authenticated. (Using OAuth Keys) Rather than just grabbing the publicly available information.
It seems like since you want a small piece of information (the public headline of any user) you'd want some sort of implementation like Facebook's OpenGraph. After looking around on LinkedIn, I don't see any sort of public implementation like that.
I would suggest checking out this gem:

It seems to be the type of solution you're looking for.
I am using the omniauth-facebook gem in rails 3 following the tutorial at http://blog.railsrumble.com/blog/2010/10/08/intridea-omniauth.
I am inspecting Facebook's response using
render :text => request.env['omniauth.auth']
Only the following is being returned:
# extra=#> info=#> provider="facebook" uid="12345678">
In other words, only the uid is being returned. I can't figure out why none of the other basic info is coming up for the user especially since the UID is showing up. Any ideas?
request.env['omniauth.auth'] is a hash made by Omniauth that contains all the data sent by the provider. It also contains another hash called extra which also contains another hash called raw_info - all the data sent (in this case) by Facebook's Graph API.
For example, you can access the user's email using
request.env['omniauth.auth']['extra']['raw_info']['email']
Source
I'm using Omniauth to get credentials from Twitter for a specific User. Part of the OmniAuth object that I get is like this:
credentials=#
<Hashie::Mash secret="XXXX" token="XXXX">
extra=#<Hashie::Mash access_token=#<OAuth::AccessToken:xxxx #token="xxxx", #secret="xxxxx", ..
Right now I'm storing the credentials[token] and the UID for that specific User. At some point I want to fetch the Twitter API using the auth for that specific User to avoid getting the 150 max requests for a specific IP. Right now I'm just doing this:
twitter_user_name = Twitter.user(user_id).screen_name
So, how can I do to make those requests using the Twitter gem using the auth provided by OmniAuth instead of doing requests from my own IP (unauthenticated calls and therefore limited)
After playing with the gem, I've figured how to do it:
You want to create a new API object for a specific User, so you want to do this:
client = Twitter::Client.new(:oauth_token => 'XXXXX', :oauth_token_secret => 'XXXX')
And use this client to do the requests.
