Building TwitterVote
So now that we know a little bit about Twitter, let's discuss the application we are going to build. This web-based application will poll your own user account looking for a keyword that determines a poll has started and find the valid parameters for that poll (either a numeric value or a choice of text values).
The application will then poll the list of replies to your Twitter account and determine which of those are valid poll responses. These responses will be tabulated and displayed on a web page.
Twitter: Under the Hood
Twitter exposes its API via Representational State Transfer (REST). Simply, this means the API is exposed via the Web and will return a chunk of data in a defined format. The following are some examples from Twitter's API. Note that the format can be XML, JSON, RSS, or ATOM, depending on the API. To switch formats, just change the .xml extension to .json, .rss, or .atom to retrieve data in the specified format. User tweets: http://twitter.com/statuses/user_timeline/coding4fun.xml
User friends: http://twitter.com/statuses/friends_timeline.xml
User replies: http://twitter.com/statuses/replies.xml
API call counter: http://twitter.com/account/rate_limit_status.xml
The Twitter API
Twitter's API model can be found at http://apiwiki.twitter.com/. The supported calls you can currently make against the API are listed in Table 6-1.
