用slim写的一个RESTful服务

php写rest服务，以下是一些资料和一个例子。仅供学习。

REST 资料：http://www.sitepoint.com/rest-can-you-do-more-than-spell-it-1/

SLIM资料：http://www.slimframework.com/（官网）

http://minimee.org/php/slim（中文文档）

https://github.com/codeguy/Slim-Extras/tree/master/Middleware（Slim的一些插件开源地址）

SLIM示例：http://www.sitepoint.com/writing-a-restful-web-service-with-slim/

同时推荐一个PHP数据库ORM类：http://www.notorm.com/

下面是我的例子：

• GET /books: Retrieve a list of items
• GET /book/123: Retrieve item 123
• POST /book: Create a new item
• PUT /book/123: Update item 123
• DELETE /book/123: Remove item 123

<?php

//导入类库
require 'Slim/Slim.php';

//注册Slim框架自带的自动加载类
\Slim\Slim::registerAutoloader();

$password = "";

require "NotORM.php";
$pdo = new PDO($dsn, $username, $password);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
//设置编码
$pdo->query('SET NAMES utf8');
$db = new NotORM($pdo);
