I am trying to write a code in ruby on rails that would go into facebook and pull out data to populate my database based on key words that I manually add inside the code. Anyone has done something similar or can help me with it by pointing me towards the right direction? Also I need the code to stay "alive" after the first run in order to update my site automatically. I've looked for a fb API but i couldn't find anything.
Thanks,
Crematorio
The Facebook Graph API is what you would use to pull out data, typically the feed. As for Ruby on Rails, many ways to interact with the FB Graph, but I think the Koala gem is your ticket: https://github.com/arsduo/koala
You would need to set up an application at the FB Developers site, then pass the ID/secret to authenticate via Oauth. I use the following to pull wall feed, this little bit might get you started...
oauth = Koala::Facebook::OAuth.new('app ID here', 'app secret here', 'website/project url')
graph = Koala::Facebook::GraphAPI.new(oauth.get_app_access_token)
feed = graph.get_connections("facebook username here", "feed")
#facebook_feed = ActiveSupport::JSON.decode(feed.to_json)
Adapt this however you like, what I would probably do is a rake task that checks the results of #facebook_feed and processes them based on criteria, keywords, etc.

So, I'm very new to this. I got a generated json file from my google developer console that holds information like private keys, client id, token stuff, etc.
Now, I'm trying to use the Google Analytics Report V4 api. I put all my code into a concern, and when I run the code I get this error:
Google::Apis::AuthorizationError: Unauthorized
So I know that I have to authorize my app, but I'm not sure how. I have this json file which appears to have all the information I need to authenticate my app.
After some research, I know that (on the following code) I need to assign analytics.authorization to something, I just don't know to what.
analytics = Google::Apis::AnalyticsreportingV4::AnalyticsReportingService.new
analytics.authorization = ???
Do you know of any method I'm supposed to call that takes in the location of my json file as a parameter or something that can in turn, authorize my rails app?
Thank you so so much if you can help.
I know there are other questions like this. But they use omniauth with devise I think, and I can't do that. I already have a specific context in which users need to be logged in to my app, so logging in with google wouldn't work in my case. Also, other question/answers that don't involve omniauth and devise are outdated or don't have an accepted answer.
I'm trying to use the Flickraw gem to upload some images to my account in Flickr. I get this to work, but how to get the access code, without to visit Flickr page, like this:
token = flickr.get_request_token
auth_url = flickr.get_authorize_url(token['oauth_token'], :perms => 'delete')
puts "Open this url in your process to complete the authication process : #{auth_url}"
puts "Copy here the number given when you complete the process."
verify = gets.strip
...
I don´t understand this process.
This is because the auth process is done using OAuth, explained here: http://www.flickr.com/services/api/auth.oauth.html
It's basically making the request to the flickr server getting an access token for the currently signed in user and returning that to an call back URL on your server(The docs explain it way better and in much more details so I recommend reading that instead).
If however you want to use the application only in your name you can look into other authentication mechanisms, explained here: http://www.flickr.com/services/api/auth.spec.html
The one you want to use - as it looks to me - is the non web based authentication. This is a much easier way to authenticate and only uses a key and secret for authentication. Which also seems to be supported by the FlickRaw gem: http://hanklords.github.io/flickraw/ (Look at the first simple example)
I'm using YoutubeAPI v3.0 to automatically upload videos to my own channel. However the script still needs manual intervention during Oath2.0 authorization. How to make it completely automatic?
1) Access the API using username and password
2) Or find a way to create permanent OAuth2.0 authentication
P/S: I use this script to upload

The only thing I can think of is web scraping. Basically, programmatically open the web page and get its HTML. Then find the authorization code, and store it as a string. I don't know if your scripting language of choice can do it, but Python has Beautiful Soup (links at the bottom). The problem, of course, is accessing the contents of a page like that which is pretty clearly designed to be reached by a logged in user from a web browser. I've never done that, but there's some concept of a "login handshake" where you post the data to the server that's needed as you access the page. I've a few links at the bottom.
Anyway, to give you a better idea of what I mean in pseudo-code (for those who may be confused), it'd be something like:
webURL = 'http://any-url.net";
webPageObject = openPage(webURL);
pageHTML = webPageObject.getHTML();
theHTMLTag = searchForTagById(pageHTML, "<p id='oAuthMessage'>");
//And from there, figure out where the string containing the code is.
//Probably just by getting a substring from the end of the text in the <p>
//backward until you reach the length of the oAuth code.
You'll have to look at the page source to know which tags to look for specifically, but this can all just be done programmatically/automatically, as you wanted.

You can use get Google OAUTH2 for devices in order to have fully automatic token renewal process.
So all you need now is:
Request a device code and confirmation code
Enter confirmation code to confirm your application have access for specific account
Generate new or renew existing ACCESS_TOKEN for your device code
Upload Video using your device code and valid ACCESS_TOKEN
Here is documentation for it.
And here is some examples.
Using MVC4, I would like to get the recent Tweets (3) of user's without having to request access from them, because that is a pain for the user. This is also because a user may be viewing another user and I would also like to display their Tweets.
This was fairly simple with Twitter API v1:
$.ajax({
url: 'https://api.twitter.com/1/statuses/user_timeline.json?count=3&screen_name=' + twitterUser,
...
});
..but its deprecated and will stop working in about two months from now.
I'm new to Oauth and have struggled to find any good material on how to get a user's Tweets, but I believe the process is a lot more complicated now with the Twitter API v1.1? Ideally, I'd like to achieve everthing in the front end, but think that I now need to do some authentication server side and will have to use MVC?
In order to get any user's Tweets, I was thinking that I could create a Twitter account for my application and use that to get anyone's Tweets, as long as they are not protected.
Does anyone know of any good libraries that I can use to achieve this, or is the out of the box MVC4 Oauth stuff alone enough to do the job?
Any suggestions of where to start, and especially examples would be greatly appreciated.
To use API 1.1, you have to have a Twitter account and a Twitter application and then use OAUTH to authenticate your rate limited requests using GET statuses/show/:id. The only alternative I know is RSS which both Twitter & Facebook have kiiled, briught back and threatened to kill again:
http://api.twitter.com/1/statuses/user_timeline.rss?screen_name={USERNAME}
I decided to use Linq2Twitter, as this makes use of the V1.1 API.
An MVCDemo example of Linq2Twitter stores the authorised credentials in a SessionStateCredentials object, but I can store the object in cache and persist the authorisation for all users, meaning they won't have to authorise anything. Provided that a user's Tweets aren't protected, the Tweet's for any user should be retrievable this way.
I am building an api for others to use. This is a simple enough Json request the user passes as some data and we pass some back.
What I would love is to secure our api and have some sort of user system where we can turn users on and off and we can log how many requests each user makes.
What would be the best way to do this in Rails? I don't want it to slow down the request. I can see ways of doing it using devise maybe but would be great to hear other people's opinions.
Thanks
Another way is to use 3scale (http://www.3scale.net) - it's free up to a traffic cap but handles all the key management, users, documentation etc. and there's a ruby library which you can drop into your code if you're using rails. (other libs are here: https://support.3scale.net/libraries).
I've done this before using the Token Authentication capabilities of devise (see https://github.com/plataformatec/devise ).
I found the following setup works:
Create a user account for each api user.
Configure devise for token authentication
Set the Token Authentication configuration to require the token to be submitted with each request.
This will allow you to enable and disable individual users as well as to track every request back to the api user that made the call.
If you're really interested in tracking usage you may want to consider also creating a database table where you track all api requests. This can be setup to belong_to the users table so that you easily find all requests from different users (e.g., #user.api_requests).
The count of all requests made by a user would be:
#user.api_requests.count
# or use a where clause to find how many of each type
#user.api_requests.where("api_request_type = ?", 'SomeAPICallType').count
One final note -- I recently used the Grape library for building out an API. I thought it was pretty well done and it worked great for our needs. I especially like the ability it provided to version APIs. Details are here: https://github.com/intridea/grape/wiki
