oauth2.0服务端与客户端搭建

oauth2.0服务端与客户端搭建 - 推酷

今天搭建了oauth2.0服务端与客户端。把搭建的过程记录一下。具体实现的功能是:client.ruanwenwu.cn的用户能够通过 server.ruanwenwu.cn的用户名和密码登陆client.ruanwenwu.cn。并且登陆 后,client.ruanwenwu.cn的用户能获取server.ruanwenwu.cn哪里的一些资源。

我的个人博客原文地址: http://www.ruanwenwu.cn/2015/12/oauth-server-and-client-install.html

一、oauth2.0的作用

1、搭建第三方登录平台(就像你用很多网站支持qq登录。其实是qq提供的oauth2.0服务端支持。网站作为第三方,只要用oauth2.0标准请求服务端,求能得到用户信息,并实现登录)。

2、公共资源管理。

就 像你(Y)想通过一个打印照片的网站(A)来打印你存放在google(B)的照片。你就要通过这个A来获取B的照片。B肯定要验证是否是他的用户Y的请 求,验证通过才把照片传递给A实现打印。问题是Y不想把账号密码直接给A。用oauth2.0就是来解决这个问题的:

A先 把Y导向B的站点进行授权。授权通过,B向A发送oauth_code。A拿到这个oauth_code,连同A的client_id和 oauth_secrete发送给B,如果数据正确,B就会给A发送oauth_token。有了这个token,A就可以获取B的相关资源的。

基本的流程是这样。下面是具体的实现过程。

二、oauth2.0服务端的搭建。

oauth2.0的服务端分为验证服务器和资源服务器。这两个服务器也可以是同一个服务器(只不过把这两个功能用一个 服务器来完成罢了)。

说明:我的实现都在Thinkphp3.2.3框架下实现。

1、下载thinkphp3.2.3。

2、配置虚拟机server.ruanwenwu.cn

3、在Thinkphp的Home应用下修改配置文件(server.ruanwenwu.cn/Application/Home/Conf/config.php)如下所示:

<?php
return array(
//'配置项'=>'配置值'
//数据库设置
'DB_TYPE' => 'mysql',
'DB_HOST' => '127.0.0.1',//localhost
'DB_NAME' => 'oauth',
'DB_USER' => 'root',
'DB_PWD' => 'root',
'DB_PORT' => '3306', 'SCOPE_INFO' => array( //这是授权选项。根据你自己的项目来
array(
'name' => '个人信息',
'value' => 'basicinfo'
),
array(
'name' => '论坛发帖回帖',
'value' => 'bbsinfo'
),
), 'OAUTH2_CODES_TABLE' =>'oauth_code', //这里是oauth项目需要用的三个基础表
'OAUTH2_CLIENTS_TABLE' =>'oauth_client',
'OAUTH2_TOKEN_TABLE' =>'oauth_token', 'SECRETKYE' => 'Mumayi!@#', //下面是一些网站自定义的项目。可以根据自己的情况来写或者不写
//session 有效期
'SESSION_EXPIRES' => 1200,
//key 有效期
'PASS_KEY_EXPIRES' => 86400,
//key 有效期
'PHONE_KEY_EXPIRES' => 300,
//key 加密 整型 数字 必须为 int
'PASS_KEY_CALC' => 1314,
);

4、建oauth表。

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for oauth_client
-- ----------------------------
DROP TABLE IF EXISTS `oauth_client`;
CREATE TABLE `oauth_client` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`client_id` varchar(32) NOT NULL,
`client_secret` varchar(32) NOT NULL,
`redirect_uri` varchar(200) NOT NULL,
`create_time` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; -- ----------------------------
-- Table structure for oauth_code
-- ----------------------------
DROP TABLE IF EXISTS `oauth_code`;
CREATE TABLE `oauth_code` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`client_id` varchar(32) NOT NULL,
`user_id` int(11) NOT NULL DEFAULT '1',
`code` varchar(40) NOT NULL,
`redirect_uri` varchar(200) NOT NULL,
`expires` int(11) NOT NULL,
`scope` varchar(250) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=57 DEFAULT CHARSET=utf8; -- ----------------------------
-- Table structure for oauth_token
-- ----------------------------
DROP TABLE IF EXISTS `oauth_token`;
CREATE TABLE `oauth_token` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`client_id` varchar(32) NOT NULL,
`user_id` int(11) NOT NULL,
`access_token` varchar(40) NOT NULL,
`refresh_token` varchar(40) NOT NULL,
`expires_in` int(11) NOT NULL,
`scope` varchar(200) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=26 DEFAULT CHARSET=utf8;

5、引入oauth2.0服务端类文件。

5-1、在\server.ruanwenwu.cn\ThinkPHP\Library\Vendor\目录下建立oauth目录。

5-2、引入oauth2.0服务端PHP脚本。

在刚建立的oauth目录下引入OAuth2.class.php这个文件基本不用做修改。我们的操作都在继承这个类的子类上完成。类的代码如下:

<?php

* <a href="http://tools.ietf.org/html/draft-ietf-oauth-v2-10">IETF draft v10</a>.
*

代码比较多。有兴趣的可以细看。

由于采用Vendor方法引入,所以这里的文件都没有采用命名空间。

5-3、在同目录下,建ThinkOAuth2.php文件,这个文件里的类继承上面那个基类:

*/
protected function checkUserCredentials($client_id, $username, $password){
return TRUE;
} }

这里涉及到一些数据库的操作。继承出来操作,还是比较一目了然的。

5-4、准备好类了。我们就可以实现控制器里的功能代码。动手之前先搞清楚我们的意图。

首先,我们需要分配一个oauth_client和一个oauth_secrete给第三方网站(也就是client.ruanwenwu.cn)来获取oauth服务。

其次,client.ruanwenwu.cn会把用户导入到server.ruanwenwu.cn来进行授权。所以我们我们还需要准备授权页面。

因为涉及到服务端和客户端的数据交互,所以可能服务端和客户端的相关介绍我会交叉进行。

5-4-1、创建oauth_client。

5-4-2、获取oauth_cliest列表。

5-4-3、准备获取用户授权的页面和逻辑。(授权服务器)

5-4-4、准备提供用户数据的逻辑。(资源服务器)

这些逻辑我都写在一个控制器OauthController.class.php里。代码如下:

<?php
namespace Home\Controller; use Think\Controller; class OauthController extends Controller{
private $oauth = NULL; function _initialize(){ header("Content-Type: application/json");
Vendor("oauth.ThinkOAuth2");
$this -> oauth = new \ThinkOAuth2(); } public function index(){ header("Content-Type:application/json; charset=utf-8");
$this -> ajaxReturn(null, 'oauth-server-start', 1, 'json'); } public function access_token() { $this -> oauth -> grantAccessToken(); } //权限验证
public function authorize() { if (IS_POST) { if(true){
//这个地方验证成功后要把用户的uid加进来
$_POST['user_id'] = 1;
$this -> oauth -> finishClientAuthorization(true, $_POST); //第一个参数很重要,是用户是否授权
}
return;
} ///表单准备
$auth_params = $this -> oauth -> getAuthorizeParams();
$this->assign("auth_params",$auth_params);
$this->display(); } public function addclient() {
echo 'jack';
if (IS_POST) {
echo 'pd';
$res = $this -> oauth -> addClient($_POST["client_id"], $_POST["client_secret"], $_POST["redirect_uri"]);
if($res){
$this->redirect("/home/Oauth/clientlist");
die;
}
} $this->display();
} public function clientlist(){
$res = M()->table("oauth_client")->select();
$this->assign("clients",$res);
var_dump($res);
$this->display();
}
}

顺便我将用到的模板文件(server.ruanwenwu.cn\Application\Home\View\oauth目录下)也贴出来给大家参考一下:

addclient.html

<!doctype html>
<head>
<meta charset="utf-8" />
<title>这里是添加客户端界面</title>
</head>
<body>
<h1>添加客户端</h1>
<form action="" method="post" >
clientId:<input type="text" name="client_id" />
<br />
client_secrete:<input type="text" name="client_secret" />
<br />
callbackUrl:<input type="text" name="redirect_uri" />
<br />
<input type="submit" value="submit" /> </form>
</body>
</html>

authorize.html

<!doctype html>
<html>
<form action="" method="post">
用户名:<input type="text" name="username" />
<br />
密码:<input type="text" name="pwd" />
<input type="hidden" name="response_type" value="code" />
<input type="hidden" name="client_id" value="{$auth_params['client_id']}" />
<input type="hidden" name="redirect_uri" value="{$auth_params['redirect_uri']}" />
<input type="submit" value="submit" />
</form>
</html>

注意:我这里用到了几个隐藏域。这个是必须的,在post提交验证时会用到。

5-4-5、创建oauth2.0用户。

打 开server.ruanwenwu.cn/index.php/home/oauth/addcient,输入client_id和 client_secrete还有redirect_uri创建一个oauth2.0用户。其中redirect_uri是用户授权后需要跳转的地方。

到这里服务端的部署就差不多结束了。现在开始部署客户端。

三、oauth2.0客户端搭建。

1、同服务端一样搭建client.ruanwenwu.cn。(也是用thinkphp)。

2、能正常访问后。在类库中加入oauth2.0客户端类。

在\client.ruanwenwu.cn\ThinkPHP\Library\Org\Util目录下建立Oauth2.class.php,代码如下:

<?php
namespace Org\Util;
/**
* 与 OAuth2 服务器 通讯验证 核心类 (PHP版)
*
* @description OAuth2 说明请大家参考 木蚂蚁接口文档
*
*
* @author Mumayi-Team (zhaopan赵攀)

*/
class Oauth2
{
/*
* 以下几个参数 具体作用和用法 详见 木蚂蚁接口文档
*/ //分配的客户端 ID
public $client_id; //分配的客户端 密匙
public $client_secret; //获得的 用户授权 访问令牌
public $access_token; //刷新 访问令牌 (过期时使用)

public $useragent = 'Mumayi Team OAuth2 v1.0'; //是否 开启 请求调试 (开启时 将输出 详细的请求结果)
public $debug = FALSE; //边界 (CURL使用 写入在Header的分界线, 忽略)
public static $boundary = ''; //返回 OAuth 令牌 请求地址
function accessTokenURL() { return $this->host.'access_token'; } //返回 OAuth 自动授权 请求地址
function authorizeURL() { return $this->host.'authorize'; } //构造函数 赋值 一些必要参数
function __construct($client_id, $client_secret, $access_token = NULL, $refresh_token = NULL) {
$this->client_id = $client_id;
$this->client_secret = $client_secret;
$this->access_token = $access_token;
$this->refresh_token = $refresh_token;
// $this->debug = true;

注意:这个类的加载跟服务端采用的不同的方式。这里用了命名空间。服务端用的vendor。

3、准备访问链接。

我们通过这个url将用户导向server.ruanwenwu.cn进行授权,发送accesss_code操作。

我在client.ruanwenwu.cn的index控制器中实现的这个url。控制器里没有逻辑,我只贴index.html了:

<!doctype html>
<html>
<head></head>
<body>
<a href="http://server.ruanwenwu.cn/index.php/home/oauth/authorize?redirect_uri=http://client.ruanwenwu.cn/index.php/home/login&response_type=code&client_id=10009174&type=123456">登陆</a>
</body>
</html>

注 意:这个url中redirect_uri,response_type为必选参数。而且这个redirect_uri必须包含我们在服务端添加 oauth服务时写的那个redirect_uri。否则不能通过验证。(也就是说:在我们这个例子里,这个redirect_uri必须包含:

http://client.ruanwenwu.cn/index.php/home/login

4、点击链接,跳转到服务端对应的url。实际上就是server.ruanwenwu.cn的authorize操作。在这里会对用户进行验证,并判断是否授权。

    //权限验证
public function authorize() { if (IS_POST) { if(true){
//这个地方验证成功后要把用户的uid加进来
$_POST['user_id'] = 1; //这里是写死的,实际上是从数据库读出来
$this -> oauth -> finishClientAuthorization(true, $_POST); //第一个参数很重要,是用户是否授权
}
return;
} ///表单准备
$auth_params = $this -> oauth -> getAuthorizeParams();
$this->assign("auth_params",$auth_params);
$this->display(); }

注意看我在这个操作里写的注释。

验证成功后,页面又跳回到我们之前写的redirect_uri,并带上了code参数,这就是验证服务器向客户端发送的access_code。

5、客户端拿到access_code,向验证服务器请求access_token。

在我的client.ruanwenwu.cn的loginController.class.php中进行:

<?php
namespace Home\Controller; use Think\Controller;
use Org\Util\Oauth2;
class LoginController extends Controller{
public function _initialize(){ } public function index(){
$this->oauth = new Oauth2('10009174','123456');
$keys = array();
//keys 数组 赋值 code 值 (换取token, 必须参数)
$keys['code'] = $_GET['code'];
//keys 数组 赋值 回调地址信息 (换取token, 必须参数)
$keys['redirect_uri'] = 'http://client.ruanwenwu.cn/index.php/home/login?type=mumayidev';
//根据 code 获取 token
//var_dump( $token = $this->oauth->getAccessToken( 'code', $keys )) ;
$token = $this->oauth->getAccessToken( 'code', $keys ) ; //现在已经得到token,并且将access_token写到对象里了。就可以请求资源了
var_dump( $this->oauth->get_uid());
die;
}
}
   $token = $this->oauth->getAccessToken( 'code', $keys ) ;    //这就是请求代码。code是验证方式。$keys数组里要code和redirect_uri。在服务器端需要验证

服务端的响应是这样的:

验证client.ruanwenwu.cn的client_id和secrete是否合法,还要判读access_code是否过期

    public function access_token() {

        $this -> oauth -> grantAccessToken();    //这个方法里有所有的验证及生成access_token的操作。(会有数据库的写入)

    }

服务端生成access_token之后,会返回给客户端。

客户端拿到access_token之后,向资源服务器请求用户资源:

在这里我的验证服务器和资源服务器都是server.ruanwenwu.cn。我用resourceController.class.php来做资源控制:

<?php
namespace Home\Controller; use Think\Controller; class ResourceController extends Controller{
protected $db;
public function _initialize(){
$this->db = M();
}
public function userinfo(){
// $arr = array("username"=>"阮文武","sex"=>1,"img"=>"http://weewrerfdf");
// echo json_encode($arr);
// die;
if(isset($_GET['access_token']) && $_GET['access_token']){
$res = $this->db->table("oauth_token")->where("access_token = '".$_GET['access_token']."'")->find();
if($res && count($res) > 0){
if($res['expires_in'] > time()){
$arr = array("username"=>"阮文武d","sex"=>1,"img"=>"http://weewrerfdf");
echo json_encode($arr);
die;
}
}
};
}
}

如果access_token有效,就查到用户id,取出用户的信息。我这里只是做测试,所以就直接自己返回了数据。原本写的很详细,后来因为内容字段是text,没保存完整,这会时间比较赶,就写的简单一点。

再抽时间补充吧。

欢迎大家与我讨论哦。
