What is REST  API In Web

参考:http://www.infoq.com/cn/articles/rest-introduction

REST stands for Representational State Transfer, and it was proposed in a doctorate dissertation. It uses the four HTTP methods GET, POST, PUT and DELETE to execute different operations. This in contrast to SOAP for example, which creates new arbitrary commands (verbs) like getAccounts() orapplyDiscount()

A REST API is a set of operations that can be invoked by means of any the four verbs, using the actual URI as parameters for your operations. For example you may have a method to query all your accounts which can be called from /accounts/all/ this invokes a HTTP GET and the 'all' parameter tells your application that it shall return all accounts
