Exposing an API

APIs are becoming an essential feature of modern web applications. Rails does a good job of helping your application provide an API using the same MVC structure you're accustomed to.

In the Controller

Let's work with the following example controller:

class ArticlesController &lt; ApplicationController

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.
