本文實(shí)例講述了Yii2中OAuth擴(kuò)展及QQ互聯(lián)登錄實(shí)現(xiàn)方法。分享給大家供大家參考，具體如下：

代碼如下:

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

Quick start 快速開始

更改Yii2的配置文件config/main.php，在components中增加如下內(nèi)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增加代碼，同時增加回調(diào)函數(shù)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

 }

}

在登錄的Views中，增加如下代碼

<?= yii\authclient\widgets\AuthChoice::widget([

 'baseAuthUrl' => ['site/auth']

])?>

以上是官方的說明文檔，下面我們來接入QQ互聯(lián)

增加QQ登錄的組件 我這里是放在 common/components/QqOAuth.php 中，源代碼如下

<?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/

 * @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';

 }

 /**

 * 該擴(kuò)展初始的處理方法似乎QQ互聯(lián)不能用，應(yīng)此改寫了方法

 * @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) {

   //以下代碼是特別針對QQ互聯(lián)登錄的，也是與原方法不一樣的地方 

         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;

         }

   //代碼添加結(jié)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 就按官方那樣子

public function successCallback($client)

{

 $attributes = $client->getUserAttributes();

 // 用戶的信息在$attributes中，以下是您根據(jù)您的實(shí)際情況增加的代碼

 // 如果您同時有QQ互聯(lián)登錄，新浪微博等，可以通過 $client->id 來區(qū)別。

}

最后在登錄的視圖文件中 增加QQ登錄鏈接

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

希望本文所述對大家基于Yii框架的PHP程序設(shè)計(jì)有所幫助。
