前奏
系統:Ubuntu
語言:PHP7
框架:YAF
OAuth2.0:bshaffer/oauth2-server-php
OAuth2.0
有很多開原始碼庫
Github 排名前兩位
thephpleague/oauth2-server
bshaffer/oauth2-server-php
本文使用的是第二個:bshaffer
。原因:使用簡單,可以很快上手,文件齊全,功能完善。

引入 OAuth2.0 的 Server 端原始碼
編輯 Composer.json
檔案
{
"require": {
"bshaffer/oauth2-server-php" : "v1.10.0"
}
}

Yaf 框架中,在 Bootstrap.php
檔案中自動載入 OAuth2.0
public function _initLoader(Yaf_Dispatcher $dispatcher)
{
include(APP_PATH . `/vendor/autoload.php`);
}
新建一個 Controller 檔案:Oauth.php
,在裡面建立幾個 Action
AuthorizeAction() 服務端:提供授權
TokenAction() 服務端:提供Token
ResourceAction() 服務端:提供資源
IndexAction() 客戶端:模擬第三方接入
_server() 服務端:初始化伺服器相關,如:儲存,這裡採用mysql
名稱空間
use OAuth2Server;
use OAuth2StoragePdo;
use OAuth2GrantTypeAuthorizationCode;
use OAuth2GrantTypeClientCredentials;
use OAuth2GrantTypeUserCredentials;
use OAuth2Request;
use OAuth2Response;
_server() 函式程式碼
private function _server()
{
$dbParams = array(
`dsn` => `mysql:host=127.0.0.1;port=3306;dbname=oauth;charset=utf8;`,
`username` => `root`,
`password` => `123456`,
);
// $dsn is the Data Source Name for your database, for exmaple "mysql:dbname=my_oauth2_db;host=localhost"
$storage = new Pdo($dbParams);
// Pass a storage object or array of storage objects to the OAuth2 server class
$server = new Server($storage);
// Add the "Client Credentials" grant type (it is the simplest of the grant types)
$server->addGrantType(new ClientCredentials($storage));
// Add the "Authorization Code" grant type (this is where the oauth magic happens)
$server->addGrantType(new AuthorizationCode($storage));
return $server;
}
IndexAction() 程式碼
public function indexAction()
{
$uri = $_SERVER[`QUERY_STRING`];
$code = substr($uri, strpos($uri, `code=`)+5, 40);
$state = substr($uri, strpos($uri, `state=`)+6);
if ($code) {
$params = array(
`code` => $code,
`state` => $state,
`client_id` => `client_id`,
`client_secret` => `client_secret`,
`grant_type` => `authorization_code`,
`scope` => `basic`,
`redirect_uri` => `http://yourhost/user/oauth/index`,
);
$url = `http://yourhost/user/oauth/token`;
$result = $this->httpPost($url, $params);
$result = json_decode($result, true);
//寫入Session,便於測試
Yaf_Session::getInstance()->set(`access_token`,$result[`access_token`]);
return false;
} else {
//客戶端請求授權之前,頁面中展示一個連結,使用者點後,可以跳轉至服務端的授權頁面。
$this->getView()->assign(`data`, array())->render(`oauth/index.php`);
}
}
對應的模板程式碼:oauth/index.php
<div>
<a href="http://yourhost/User/Oauth/Authorize?response_type=code&client_id=client_id&redirect_uri=http://yourhost/user/oauth/index&scope=basic&state=xxx">click here</a>
</div>
AuthorizeAction() 程式碼
/**
* 展示授權頁面,使用者可以點選同意進行授權
*/
public function AuthorizeAction()
{
$request = Request::createFromGlobals();
$is_authorized = $request->request(`is_authorized`) ? true : false;
//判斷使用者是否同意授權
if ($is_authorized) {
$response = new Response();
$server = $this->_server();
// validate the authorize request
if (!$server->validateAuthorizeRequest($request, $response)) {
$response->send();
die;
}
$server->handleAuthorizeRequest($request, $response, $is_authorized)->send();
return false;
}
//將請求授權中帶來的各個引數,寫入授權頁中的變數,用以授權表單POST提交。
$renderData = $_GET;
$this->getView()->assign(`data`, $renderData)->render(`oauth/authorize.php`);
}

public function TokenAction()

ResourceAction() 程式碼
public function ResourceAction()
{
$server = $this->_server();
//獲取授權使用者Session中儲存的access_token,用access_token可以請求許可權範圍內的所有介面
$_POST[`access_token`] = Yaf_Session::getInstance()->get(`access_token`);
// Handle a request to a resource and authenticate the access token
if (!$server->verifyResourceRequest(Request::createFromGlobals())) {
$server->getResponse()->send();
die;
}
echo json_encode(array(`success` => true, `message` => `You accessed my APIs!`));
return false;
}
請求使用者資源:/user/oauth/resource
{
success: true,
message: "You accessed my APIs!"
}
實現思路:
- URL請求:/user/oauth/index,
Client端
對應的模板裡放置一個連結,用以跳轉至服務端的授權認證頁面/user/oauth/authorize。授權成功後,服務端會將對應的code和state引數,附在回撥的redirect_uri裡,即:/user/oauth/index?code=fcd6a9589e7ab43398e4e5349b23846babc79fab&state=xxx,在indexAction中解析出回撥的code,用以請求介面/user/oauth/token,來交換access_token。
- URL請求:/user/oauth/authorize,
Server端
對應的模板裡是告知使用者,即將授予的許可權列表,以及是否允許授權的按鈕。 - URL請求:/user/oauth/token,
Server端
獲取access_token。 - URL請求:/user/oauth/resource,
Server端
獲取使用者資源
LAST:
- 各種授權型別,都可以很方便支援。
- 資料儲存層,也可以隨意切換,比如切換為
Redis
