Yii2中OAuth扩展及QQ互联登录实现方法

本文实例讲述了Yii2中OAuth扩展及QQ互联登录实现方法。分享给大家供大家参考，具体如下：

代码如下：

php composer.phar require --prefer-dist yiisoft/yii2-authclient "*"

Quick start 快速开始

更改Yii2的配置文件config/main.php，在components中增加如下内容

'components' => [
 'authClientCollection' => [
 'class' => 'yii\authclient\Collection',
 'clients' => [
  'google' => [
  'class' => 'yii\authclient\clients\GoogleOpenId'
  ],
  'facebook' => [
  'class' => 'yii\authclient\clients\Facebook',
  'clientId' => 'facebook_client_id',
  'clientSecret' => 'facebook_client_secret',
  ],
 ],
 ]
 ...
]

更改入口文件，一般是app/controllers/SiteController.php，在function actions增加代码，同时增加回调函数successCallback，大致如下

class SiteController extends Controller
{
 public function actions()
 {
 return [
  'auth' => [
  'class' => 'yii\authclient\AuthAction',
  'successCallback' => [$this, 'successCallback'],
  ],
 ]
 }
 public function successCallback($client)
 {
 $attributes = $client->getUserAttributes();
 // user login or signup comes here
 }
}

在登录的Views中，增加如下代码

<?= yii\authclient\widgets\AuthChoice::widget([
 'baseAuthUrl' => ['site/auth']
])?>

以上是官方的说明文档，下面我们来接入QQ互联

增加QQ登录的组件 我这里是放在 common/components/QqOAuth.php 中，源代码如下

<?php
namespace common\components;
use yii\authclient\OAuth2;
use yii\base\Exception;
use yii\helpers\Json;
/**
 *
 * ~~~
 * 'components' => [
 * 'authClientCollection' => [
 *  'class' => 'yii\authclient\Collection',
 *  'clients' => [
 *  'qq' => [
 *   'class' => 'common\components\QqOAuth',
 *   'clientId' => 'qq_client_id',
 *   'clientSecret' => 'qq_client_secret',
 *  ],
 *  ],
 * ]
 * ...
 * ]
 * ~~~
 *
 * @see http://connect.qq.com/
 *
 * @author easypao <[email protected]>
 * @since 2.0
 */
class QqOAuth extends OAuth2
{
 public $authUrl = 'https://graph.qq.com/oauth2.0/authorize';
 public $tokenUrl = 'https://graph.qq.com/oauth2.0/token';
 public $apiBaseUrl = 'https://graph.qq.com';
 public function init()
 {
 parent::init();
 if ($this->scope === null) {
  $this->scope = implode(',', [
  'get_user_info',
  ]);
 }
 }
 protected function initUserAttributes()
 {
 $openid = $this->api('oauth2.0/me', 'GET');
 $qquser = $this->api("user/get_user_info", 'GET', ['oauth_consumer_key'=>$openid['client_id'], 'openid'=>$openid['openid']]);
 $qquser['openid']=$openid['openid'];
 return $qquser;
 }
 protected function defaultName()
 {
 return 'qq';
 }
 protected function defaultTitle()
 {
 return 'Qq';
 }
 /**
 * 该扩展初始的处理方法似乎QQ互联不能用，应此改写了方法
 * @see \yii\authclient\BaseOAuth::processResponse()
 */
 protected function processResponse($rawResponse, $contentType = self::CONTENT_TYPE_AUTO)
 {
   if (empty($rawResponse)) {
     return [];
   }
   switch ($contentType) {
     case self::CONTENT_TYPE_AUTO: {
       $contentType = $this->determineContentTypeByRaw($rawResponse);
       if ($contentType == self::CONTENT_TYPE_AUTO) {
   //以下代码是特别针对QQ互联登录的，也是与原方法不一样的地方 
         if(strpos($rawResponse, "callback") !== false){
           $lpos = strpos($rawResponse, "(");
           $rpos = strrpos($rawResponse, ")");
           $rawResponse = substr($rawResponse, $lpos + 1, $rpos - $lpos -1);
           $response = $this->processResponse($rawResponse, self::CONTENT_TYPE_JSON);
           break;
         }
   //代码添加结束
         throw new Exception('Unable to determine response content type automatically.');
       }
       $response = $this->processResponse($rawResponse, $contentType);
       break;
     }
     case self::CONTENT_TYPE_JSON: {
       $response = Json::decode($rawResponse, true);
       if (isset($response['error'])) {
         throw new Exception('Response error: ' . $response['error']);
       }
       break;
     }
     case self::CONTENT_TYPE_URLENCODED: {
       $response = [];
       parse_str($rawResponse, $response);
       break;
     }
     case self::CONTENT_TYPE_XML: {
       $response = $this->convertXmlToArray($rawResponse);
       break;
     }
     default: {
       throw new Exception('Unknown response type "' . $contentType . '".');
     }
   }
   return $response;
 }
}

更改 config/main.php 文件，在components中增加，大致如下

'components' => [
 'authClientCollection' => [
   'class' => 'yii\authclient\Collection',
   'clients' => [
     'qq' => [
      'class'=>'common\components\QqOAuth',
      'clientId'=>'your_qq_clientid',
      'clientSecret'=>'your_qq_secret'
    ],
   ],
 ]
]

SiteController.php 就按官方那样子

public function successCallback($client)
{
 $attributes = $client->getUserAttributes();
 // 用户的信息在$attributes中，以下是您根据您的实际情况增加的代码
 // 如果您同时有QQ互联登录，新浪微博等，可以通过 $client->id 来区别。
}

最后在登录的视图文件中 增加QQ登录链接

<a href="/site/auth?authclient=qq">使用QQ快速登录</a>
