To obtain a requested resource, call the WebTarget.request().get() method, which will return a
javax.ws.rs.core.Response object. The returned Response can be used to process the results accordingly,
depending upon the results you are trying to achieve within the client. In the example, the Response object's
readEntity method is called, which simply returns the results in the requested format. In the example, a
String.class is passed to the readEntity method, implying that a response should be returned in String format.
To see a complete list of methods that can be called against a Response object, please refer to the online
documentation ( http://docs.oracle.com/javaee/7/api/javax/ws/rs/core/Response.html ) because the list is
quite lengthy.
It is possible to filter a response by chaining methods, as needed, to specify headers, cookies, and so on, off
of the request method. Each of these chained method calls returns a Builder object, which can be further built
