Yii2中OAuth擴展及QQ互聯登錄實現方法

本文實例講述了Yii2中OAuth擴展及QQ互聯登錄實現方法。分享給大家供大家參考，具體如下：

復制代碼代碼如下:

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，同時增加回調函數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

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

<?phpnamespace 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 <admin@easypao.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 $qquser; } protected function defaultName() { return 'qq'; } protected function defaultTitle() { return 'Qq'; } /** * 該擴展初始的處理方法似乎QQ互聯不能用，應此改寫了方法 * @see /yii/authclient/BaseOAuth::processResponse() */ protected function processResponse($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，以下是您根據您的實際情況增加的代碼 // 如果您同時有QQ互聯登錄，新浪微博等，可以通過 $client->id 來區別。}

最后在登錄的視圖文件中增加QQ登錄鏈接
