RESTFUL接口学习之Phalcon版

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

$app->post('/api/robots/', function() use ($app) {
    $robot = new Robots;
    $robot->name = $app->request->getPost('name');
    $robot->type = $app->request->getPost('type');
    $robot->year = $app->request->getPost('year');

    $response = new Phalcon\Http\Response();
    if ($robot->save() == true) {
        $response->setStatusCode(201, 'Created');
        $robot->id = $robot->id;
        $response->setJsonContent(array('status' => 'OK', 'data' => $robot->toArray()));
    } else {
        getErrors($response, $robot);
    }
    return $response;
};

function getErrors($response, $robot)
{
    $response->setStatusCode(409, "Conflict");
    $errors = array();
    foreach ($model->getMessages() as $message) {
        $errors[] = $message->getMessage();
    }

    $response->setJsonContent(array('status' => 'ERROR', 'message' => $errors));
}

更新数据

$app->put('/api/robots/{id:[0-9]+}', function($id) use($app) {
    $robot = Robots::findFirst(array(
        "id = ?0",
        "bind" => array($id)
    ));

    $response = new Phalcon\Http\Response();
    if (!$robot) {
        $response->setJsonContent(array('status' => 'NOT-FOUND'));
    } else {
        $robot->name = $app->request->getPut('name');
        $robot->type = $app->request->getPut('type');
        $robot->year = $app->request->getPut('year');
        if ($robot->save()) {
            $response->setJsonContent(array('status' => 'OK'));
        } else {
            getErrors($response, $robot);
        }
    }
    return $response;
});

等等。
