Learning Play! Framework 2

By: Andy Petrella

Overview of this book

<p>The Learning Play! Framework 2 has been created for web developers that are building web applications. The core idea is to focus on the HTTP features and to enable them through a simplification lens. Building a web application no longer requires a configuration phase, an environment setup, or a long development lifecycle - it's integrated!<br /><br />Learning Play! Framework 2 will enable any web developers to create amazing web applications taking advantage of the coolest features. It's the fastest way to dive into Play!, focusing on the capabilities by using them in a sample application. Although essentially Java based code, a Scala version is presented as well – giving an opportunity to see some Scala in action.<br /><br />After setting up the machine and learning some Scala, you will construct an application which builds from static to dynamic, before introducing a database. <br /><br />Then we'll focus on how data can be consumed and rendered in several ways. This will enable some real time communication through WebSocket and Server-Sent Event – on both server and client sides.</p> <p>The book will end with testing and deployment, which completes any web development project.</p>

For that, we'll look for items in the chatrum that have special patterns, that is, words starting with a hash (#) or an at sign (@). First of all, we'll see how to use Twitter to retrieve information using a browser and the API specification.

The Twitter REST API provides an entry point from which it will be able to do a lot of search operations. This entry point is the URL http://search.twitter.com/search.json. At first glance we can guess that the operations will represent the response in JSON.

In order to search on a hashtag, this URL can be set with a search parameter named q that holds the hashtag, prefixed by the well-known # character. Of course, the request is a GET one.

So let's try this in our browser; it will help us later because we'll have the opportunity to analyze the output and...
