阅读须知：理解OAuth2
OAuth是一个关于授权（authorization）的开放网络标准，在全世界得到广泛应用，目前的版本是2.0版。今天就试着把环境搭建一下在此仅作为学习记录；

数据表准备：
-- -- 表的结构 `oauth_access_tokens` -- CREATE TABLE IF NOT EXISTS `oauth_access_tokens` ( `access_token` text, `client_id` text, `user_id` text, `expires` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `scope` text ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -------------------------------------------------------- -- -- 表的结构 `oauth_authorization_codes` -- CREATE TABLE IF NOT EXISTS `oauth_authorization_codes` ( `authorization_code` text, `client_id` text, `user_id` text, `redirect_uri` text, `expires` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `scope` text, `id_token` text ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -------------------------------------------------------- -- -- 表的结构 `oauth_clients` -- CREATE TABLE IF NOT EXISTS `oauth_clients` ( `client_id` text, `client_secret` text, `redirect_uri` text ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -- 转存表中的数据 `oauth_clients` -- INSERT INTO `oauth_clients` (`client_id`, `client_secret`, `redirect_uri`) VALUES (‘demoapp‘, ‘demopass‘, ‘http://127.0.0.1/tp/index.php‘); -- -------------------------------------------------------- -- -- 表的结构 `oauth_public_keys` -- CREATE TABLE IF NOT EXISTS `oauth_public_keys` ( `client_id` varchar(80) DEFAULT NULL, `public_key` varchar(8000) DEFAULT NULL, `private_key` varchar(8000) DEFAULT NULL, `encryption_algorithm` varchar(80) DEFAULT ‘RS256‘ ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -------------------------------------------------------- -- -- 表的结构 `oauth_refresh_tokens` -- CREATE TABLE IF NOT EXISTS `oauth_refresh_tokens` ( `refresh_token` text, `client_id` text, `user_id` text, `expires` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `scope` text ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -------------------------------------------------------- -- -- 表的结构 `oauth_scopes` -- CREATE TABLE IF NOT EXISTS `oauth_scopes` ( `scope` text, `is_default` tinyint(1) DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -------------------------------------------------------- -- -- 表的结构 `oauth_users` -- CREATE TABLE IF NOT EXISTS `oauth_users` ( `username` varchar(255) NOT NULL, `password` varchar(2000) DEFAULT NULL, `first_name` varchar(255) DEFAULT NULL, `last_name` varchar(255) DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -- Indexes for table `oauth_users` -- ALTER TABLE `oauth_users` ADD PRIMARY KEY (`username`);
OAuth2 库地址：https://github.com/bshaffer/oauth2-server-php
这里我把它放在Vendor/OAuth2里；
授权请求类：
<?php
namespace Api\Controller;
class OAuth2Controller extends \Org\OAuth2\Controller
{
public function __construct()
{
parent::__construct();
}
public function authorize()
{
// validate the authorize request
if (!$this->oauth_server->validateAuthorizeRequest($this->oauth_request, $this->oauth_response)) {
$this->oauth_response->send();
die;
}
// print the authorization code if the user has authorized your client
$this->oauth_server->handleAuthorizeRequest($this->oauth_request, $this->oauth_response, true);
// this is only here so that you get to see your code in the cURL request. Otherwise, we‘d redirect back to the client
$code = substr($this->oauth_response->getHttpHeader(‘Location‘), strpos($this->oauth_response->getHttpHeader(‘Location‘), ‘code=‘) + 5, 40);
echo json_encode([‘code‘ => $code]);
//$this->oauth_response->send();
}
public function token()
{
$this->oauth_server->handleTokenRequest(\OAuth2\Request::createFromGlobals())->send();
}
}
OAuth2 库的请求封装放在：Org/OAuth2里；
<?php
namespace Org\OAuth2;
class Controller
{
protected $oauth_server;
protected $oauth_storage;
protected $oauth_request;
protected $oauth_response;
public function __construct()
{
// Autoloading (composer is preferred, but for this example let‘s just do this)
// require_once(VENDOR_PATH . ‘/OAuth2/Autoloader.php‘);
// \OAuth2\Autoloader::register();
// $dsn is the Data Source Name for your database, for exmaple "mysql:dbname=my_oauth2_db;host=localhost"
$this->oauth_storage = new \OAuth2\Storage\Pdo(array(‘dsn‘ => C(‘DSN‘), ‘username‘ => C(‘USERNAME‘), ‘password‘ => C(‘PASSWORD‘)));
// Pass a storage object or array of storage objects to the OAuth2 server class
$this->oauth_server = new \OAuth2\Server($this->oauth_storage);
// Add the "Client Credentials" grant type (it is the simplest of the grant types)
$this->oauth_server->addGrantType(new \OAuth2\GrantType\ClientCredentials($this->oauth_storage));
// Add the "Authorization Code" grant type (this is where the oauth magic happens)
$this->oauth_server->addGrantType(new \OAuth2\GrantType\AuthorizationCode($this->oauth_storage));
$this->oauth_request = \OAuth2\Request::createFromGlobals();
$this->oauth_response = new \OAuth2\Response();
}
}
<?php
namespace Org\OAuth2;
class Resource extends Controller
{
protected $tokenData;
public function __construct()
{
parent::__construct();
// Handle a request to a resource and authenticate the access token
if (!$this->oauth_server->verifyResourceRequest(\OAuth2\Request::createFromGlobals())) {
$this->oauth_server->getResponse()->send();
die;
}
$this->tokenData = $this->oauth_server->getResourceController()->getToken();
}
}
测试类：
<?php
namespace Api\Controller;
class TestController extends \Org\OAuth2\Resource
{
public function __construct()
{
parent::__construct();
}
public function test()
{
echo json_encode(array(‘success‘ => true, ‘message‘ => ‘You accessed my APIs!‘));
}
public function getToken()
{
echo json_encode([‘token‘ => $this->tokenData]);
}
}
配置文件：
require_once(VENDOR_PATH . ‘/OAuth2/Autoloader.php‘);
OAuth2\Autoloader::register();
return array(
//‘配置项‘=>‘配置值‘
‘AUTOLOAD_NAMESPACE‘ => array(‘OAuth2‘ => VENDOR_PATH . ‘OAuth2/‘), //扩展模块列表
‘DSN‘ => ‘mysql:host=localhost;dbname=oauth2‘,
‘USERNAME‘ => ‘root‘,
‘PASSWORD‘ => ‘‘,
);
