I want to create tabs on FB.
I have this code:
#graph = Koala::Facebook::API.new(Client.find(session[:id_client]).oauth_token)
#graph.put_connections("4154829881847172/tabs","POST", {:access_token => "AAABwdtYjsyoBAMcg558a4FYnZBkZBUiPKmcWWssssWoNZC2yjqE43ghoR9uTiFIhT3ErkQYx45RrrPeOD0ZCvFgnmRIUh9lqRUw5KIlWwxtRW3GvbIEUWp0yB2", :app_id => '1236553701115690'})
But I have a problem
-> OAuthException: (#210) Subject must be a page.
Is 4154829881847172 the correct ID for the page you're trying to add the tab to?
And are you definitely using the page's access token? (as opposed to a user access token for the page admin)
Either of those being incorrect means you're passing a something-other-than-a-page's ID in place of the Page ID
This did not work for me as well. And I think the reason is http://developers.facebook.com/bugs/194192344040832/. Running this on over Graph API Explorer gives the same result.
But I did using the following way
#graph = Koala::Facebook::GraphAPI.new("user_access_token")
#newgraph=Koala::Facebook::GraphAPI.new("page_access_token")
#newgraph.put_connections("me","tabs", {:app_id => 'your_app_id'})
You basically make a graph object with the page access token and then run the put_connections method.

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 putting together a website which displays Facebook events using Ruby on Rails and Koala.
I can display an event just fine if I do the following:
graph = Koala::Facebook::API.new(auth_token)
fb_event = graph.get_object(some_event_id)
But as soon as I change the first line to:
graph = Koala::Facebook::API.new(auth_token)
Ie, without the auth_token, I get an error--> type: OAuthException, code: 104, message: An access token is required to request this resource. [HTTP 400]
I don't want the user to have to be logged in in order to view the event. I know that I don't have to be logged into Facebook to view the event, so I'm sure there must be way to get the event without having to have the user be logged in. Any ideas?
Using WizKid's comment to get me there:
I went to https://developers.facebook.com/tools/access_token/
I then used my app's "User Token"
I have an FB account and i have created a fan page for my club and few other pages as well. I have an app in Ruby on Rails. I want to publish some feed on my club fan page. How can i do this?
I have been using Koala Gem and able to successfully post to my wall but not on to the page.
I want to access the list of all the fan pages associated with my account instead of giving the name of specific page.
here is my simple method which i am using to communicate to FB Graph API.
def facebook
#facebook ||= Koala::Facebook::GraphAPI.new(oauth_token)
rescue Koala::Facebook::APIError => e
logger.info e.to_s
nil # or consider a custom null object
end
Answer submitted by Sumit can be an approach but after searching around some more forums, finally i got an elegant way to do it.
#user_graph = Koala::Facebook::API.new(user_access_token)
pages = #user_graph.get_connections('me', 'accounts')
# get access token for first page
first_page_token = pages.first['access_token']
# or: retrieve access_token for a given page_id
page_token = #user_graph.get_page_access_token(page_id)
Passing on the "accounts" parameter to get_connection worked elegantly for me.
Here is the reference to API.
And one last thing, never forget to add the "manage_pages" permission in your permissions list.
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:
https://github.com/yatishmehta27/linkedin-scraper
It seems to be the type of solution you're looking for.
I hear that fb_graph is the way to go and I already have my app registered with Facebook but I don't know how to get the access token to post things. I have my app ID and secret but I need to get that access token. All I'm trying to do is post to a Facebook fan page (as the page).
How do I get the access token?
Get the user:
user = FbGraph::User.me(access_token)
user.fetch
To see the users accounts details:
user.accounts
Select the Facebook page that you want to post to:
account = user.accounts.select {|account| account if account.name == "*Your Page Name*"}.first
(account.access_token => the pages access token)
(account.identifier => page id)
Create new page instance:
page = FbGraph::Page.new(account.identifier)
Post to the page:
note = page.note!(:access_token => account.access_token, :subject => "Hello World", :message => "hey, this is a test from rails")
The step-by-step procedure for access token with Oauth 2.0 is found here: http://developers.facebook.com/docs/authentication/. If you require a sample code in Ruby, create a new app and under "Hosting URL", click on "get one" and select Ruby programming language when prompted. It also contains code to pull from Graph API.
I highly highly recommend the new gem Koala for working with facebook.
If you do a call to https://graph.facebook.com/me/accounts
and pass in your access_token it will return data listing all the pages you have access to and the access_tokens needed to post to those walls.#
You get your access token by logging in and the access token is passed back by the login process.
