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：
复制代码 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' => 'yiiauthclientCollection', 'clients' => [ 'google' => [ 'class' => 'yiiauthclientclientsGoogleOpenId' ], 'facebook' => [ 'class' => 'yiiauthclientclientsFacebook', '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' => 'yiiauthclientAuthAction', '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
<?= yiiauthclientwidgetsAuthChoice::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 commoncomponents; use yiiauthclientOAuth2; use yiibaseException; use yiihelpersJson; /** * * ~~~ * 'components' => [ * 'authClientCollection' => [ * 'class' => 'yiiauthclientCollection', * 'clients' => [ * 'qq' => [ * 'class' => 'commoncomponentsQqOAuth', * '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 $qquser; } protected function defaultName() { return 'qq'; } protected function defaultTitle() { return 'Qq'; } /** * 该扩展初始的处理方法似乎QQ互联不能用，应此改写了方法 * @see yiiauthclientBaseOAuth::processResponse() */ protected function processResponse($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 $response; } }
更改 config/main.php 文件，在components中增加，大致如下
'components' => [ 'authClientCollection' => [ 'class' => 'yiiauthclientCollection', 'clients' => [ 'qq' => [ 'class'=>'commoncomponentsQqOAuth', 'clientId'=>'your_qq_clientid', 'clientSecret'=>'your_qq_secret' ], ], ] ]
SiteController.php 就按官方那样子
public function successCallback($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">使用QQ快速登录</a>
