  1. Overview of Twitter API Nathan Liu

  2. Twitter API Essentials • Twitter API is a Representational State Transfer(REST) style web services exposed over HTTP(S). • Can be accessed with any HTTP client using either GET(accessor) and POST(mutator) methods. • Examples: • Getting a user’s profile • https://api.twitter.com/1/users/show.xml?id=comp621u • Retrieving a user’s latest tweets • https://api.twitter.com/1/statuses/user_timeline.xml?id=comp621u • Search for all tweets containing the term “twitter” • https://search.twitter.com/search.json?q=twitter

  3. Method Categories • Account: authentication • Block: blockingand unblock users • Direct message: managing messages sent between pairs of users • Favorites: getting and setting favorite tweets of users. • Friendship: checking if two users and following each other. • Social graph: getting follower and friends. • Status: retrieve, post, delete tweets • Timeline: retrieve latest collection of tweets • Trends: retrieve “trending” topics • Users: getting and setting user details.

  4. Three Major APIs • REST API: access to core data about individual users, update and retrieve timelines, status data. Most used for building • Search API: retrieving tweets with constrains on keyword, locations, time. • Streaming API: receiving real time feed for access large scale tweet stream. Can filter with keywords, user lists, locations.

  5. Working with Twitter API • Results are returned in JSON, XML or RSS format. • Documentation: • http://dev.twitter.com/doc • Client libraries available in many different languages: • http://dev.twitter.com/pages/libraries • Each free account can make a maximum of 150 requests per hour. • A web console for you to try out different methods: • https://dev.twitter.com/console • A very good python package is Tweepy (https://github.com/joshthecoder/tweepy), which supports all three APIs.

  6. Example 1: Working with Tweepy auth = tweepy.BasicAuthHandler("username", "password") api = tweepy.API(auth) auth = tweepy.OAuthHandler("consumer_key", "consumer_secret") # Redirect user to Twitter to authorize redirect_user(auth.get_authorization_url()) # Get access token auth.get_access_token("verifier_value") # Construct the API instance api = tweepy.API(auth) # Iterate through all of the authenticated user's friends for friend in tweepy.Cursor(api.friends).items(): # Process the friend here process_friend(friend) # Iterate through the first 200 statuses in the friends timeline for status in tweepy.Cursor(api.friends_timeline).items(200): # Process the status here process_status(status) # follow every follower of the authenticated user for follower in tweepy.Cursor(api.followers).items(): follower.follow()

  7. Example 2: Listen for All Tweets Containing “Obama” from tweepy.streaming import StreamListener, Stream class Listener ( StreamListener ): def on_status( self, status ): print '-' * 20 print status.text return if __name__ == "__main__":   USERNAME = "YourUsernameHere" PASSWORD = "YourPasswordHere"   listener = Listener() stream = Stream( USERNAME, PASSWORD, listener );   stream.filter( track=( "obama", ) )
