最近在看Facebook的接口，发现都是RESTFUL格式的，

于是我也想学习RESTFUL的写法，正好Phalcon上有个样例，原地址：http://docs.phalconphp.com/en/latest/reference/tutorial-rest.html 

现在用Phalcon框架做一个简单的RESTFUL服务，接口如下：

 

Method　　 Url Action
GET /api/robots 获得所有的robots
GET /api/robots/search/{name} 按名称来搜索
GET /api/robots/{id} 按ID来搜索
POST /api/robots 创建新的robot
PUT /api/robots/{id} 更新已有的robot
DELETE /api/robots/{id} 删除已有的robot

 

 

 

 

 

 

 

 

 

用Phalcon来实现很容易，如实现查询接口

$app->get('/api/robots', function() {
    $robots = Robots::find();
    echo json_encode($robots->toArray());
});

实现新建数据接口

 1 $app->post('/api/robots/', function() use ($app) {
 2     $robot = new Robots;
 3     $robot->name = $app->request->getPost('name');
 4     $robot->type = $app->request->getPost('type');
 5     $robot->year = $app->request->getPost('year');
 6 
 7     $response = new Phalcon\Http\Response();
 8     if ($robot->save() == true) {
 9         $response->setStatusCode(201, 'Created');
10         $robot->id = $robot->id;
11         $response->setJsonContent(array('status' => 'OK', 'data' => $robot->toArray()));
12     } else {
13         getErrors($response, $robot);
14     }
15     return $response;
16 };
17 
18 function getErrors($response, $robot)
19 {
20     $response->setStatusCode(409, "Conflict");
21     $errors = array();
22     foreach ($model->getMessages() as $message) {
23         $errors[] = $message->getMessage();
24     }
25 
26     $response->setJsonContent(array('status' => 'ERROR', 'message' => $errors));
27 }

更新数据

 1 $app->put('/api/robots/{id:[0-9]+}', function($id) use($app) {
 2     $robot = Robots::findFirst(array(
 3         "id = ?0",
 4         "bind" => array($id)
 5     ));
 6 
 7     $response = new Phalcon\Http\Response();
 8     if (!$robot) {
 9         $response->setJsonContent(array('status' => 'NOT-FOUND'));
10     } else {
11         $robot->name = $app->request->getPut('name');
12         $robot->type = $app->request->getPut('type');
13         $robot->year = $app->request->getPut('year');
14         if ($robot->save()) {
15             $response->setJsonContent(array('status' => 'OK'));
16         } else {
17             getErrors($response, $robot);
18         }
19     }
20     return $response;
21 });

等等。
