The implementation method of OAuth extension and QQ interconnection login in Yii2, yii2oauth

The example in this article describes the implementation method of OAuth extension and QQ interconnection login in Yii2. Share it with everyone for your reference, the details are as follows:
Copy code The code is as follows: php composer.phar require --prefer-dist yiisoft/yii2-authclient "*"

Quick start Quick start

Change the Yii2 configuration file config/main.php and add the following content in components

'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',
  ],
 ],
 ]
 ...
]

Change the entry file, usually app/controllers/SiteController.php, add code in function actions, and add the callback function successCallback, as follows

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
 }
}

In the logged-in Views, add the following code

<&#63;= yii\authclient\widgets\AuthChoice::widget([
 'baseAuthUrl' => ['site/auth']
])&#63;>

The above is the official documentation, let’s connect to QQ Internet

To add QQ login components, I put them in common/components/QqOAuth.php. The source code is as follows

<&#63;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/

 */
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;
 }
}

Change the config/main.php file and add it in components, roughly as follows

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

SiteController.php is as official as it is

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。
}

Finally, add the QQ login link in the login view file

<a href="/site/auth&#63;authclient=qq">使用QQ快速登录</a>
