REST api

Hello

What is REST ?

• REST stand for Representional State Transfer.
• It relies on stateless,client\server,cacheable communication protocol
• Uses HTTP
• Restfull applications use HTTP to post data (create/update) , read data (make queries) , and delete data

REST as Lightweight Web Service
Much like Web Services a REST service is :

• Platform independent i.e. does not care if Windows,Mac,Linux ... is used
• Language  independent i.e. Java,C#,...
• Standard based (runs over HTTP)
• Can easyly be used with firewalls

How simple is REST

To get a user details the follolwing query may be used :
http://www.acme.com/phonebook/UserDetailes/1234

1234 is the requested user id
UserDetailes is the desired info

This is a URL which is sent via HTTP GET request.

More complex REST request


http://www.acme.com/phonebook/UserDetailes?firstName=John&LastName=Doe
