(关于Yii2的RESTful教程请看:Yii2框架RESTful API教程)
最近看了一些关于RESTful的资料,自己动手也写了一个RESTful实例,以下是源码

Request.php 数据操作类
Response.php 输出类
index.php 入口文件
.htaccess 重写url
Request.php :包含一个Request类,即数据操作类。接收到URL的数据后,根据请求URL的方式(GET|POST|PUT|PATCH|DELETE)对数据进行相应的增删改查操作,并返回操作后的结果:
<?php
/**
* 数据操作类
*/
class Request
{
//允许的请求方式
private static $method_type = array('get', 'post', 'put', 'patch', 'delete');
//测试数据
private static $test_class = array(
1 => array('name' => '托福班', 'count' => 18),
2 => array('name' => '雅思班', 'count' => 20),
);
public static function getRequest()
{
//请求方式
$method = strtolower($_SERVER['REQUEST_METHOD']);
if (in_array($method, self::$method_type)) {
//调用请求方式对应的方法
$data_name = $method . 'Data';
return self::$data_name($_REQUEST);
}
return false;
}
//GET 获取信息
private static function getData($request_data)
{
$class_id = (int)$request_data['class'];
//GET /class/ID:获取某个指定班的信息
if ($class_id > 0) {
return self::$test_class[$class_id];
} else {//GET /class:列出所有班级
return self::$test_class;
}
}
//POST /class:新建一个班
private static function postData($request_data)
{
if (!empty($request_data['name'])) {
$data['name'] = $request_data['name'];
$data['count'] = (int)$request_data['count'];
self::$test_class[] = $data;
return self::$test_class;//返回新生成的资源对象
} else {
return false;
}
}
//PUT /class/ID:更新某个指定班的信息(全部信息)
private static function putData($request_data)
{
$class_id = (int)$request_data['class'];
if ($class_id == 0) {
return false;
}
$data = array();
if (!empty($request_data['name']) && isset($request_data['count'])) {
$data['name'] = $request_data['name'];
$data['count'] = (int)$request_data['count'];
self::$test_class[$class_id] = $data;
return self::$test_class;
} else {
return false;
}
}
//PATCH /class/ID:更新某个指定班的信息(部分信息)
private static function patchData($request_data)
{
$class_id = (int)$request_data['class'];
if ($class_id == 0) {
return false;
}
if (!empty($request_data['name'])) {
self::$test_class[$class_id]['name'] = $request_data['name'];
}
if (isset($request_data['count'])) {
self::$test_class[$class_id]['count'] = (int)$request_data['count'];
}
return self::$test_class;
}
//DELETE /class/ID:删除某个班
private static function deleteData($request_data)
{
$class_id = (int)$request_data['class'];
if ($class_id == 0) {
return false;
}
unset(self::$test_class[$class_id]);
return self::$test_class;
}
}
