Yii2实现QQ互联登录-php教程-PHP中文网

本文主要介绍了Yii2中OAuth扩展及QQ互联登录的方法，实例分析了OAuth扩展的相关配置与QQ互联登陆的实现技巧。需要的朋友可以参考下，希望对大家有所帮助。

具体如下：

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

&#39;components&#39; => [
 &#39;authClientCollection&#39; => [
 &#39;class&#39; => &#39;yii\authclient\Collection&#39;,
 &#39;clients&#39; => [
  &#39;google&#39; => [
  &#39;class&#39; => &#39;yii\authclient\clients\GoogleOpenId&#39;
  ],
  &#39;facebook&#39; => [
  &#39;class&#39; => &#39;yii\authclient\clients\Facebook&#39;,
  &#39;clientId&#39; => &#39;facebook_client_id&#39;,
  &#39;clientSecret&#39; => &#39;facebook_client_secret&#39;,
  ],
 ],
 ]
 ...
]

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 [
  &#39;auth&#39; => [
  &#39;class&#39; => &#39;yii\authclient\AuthAction&#39;,
  &#39;successCallback&#39; => [$this, &#39;successCallback&#39;],
  ],
 ]
 }
 public function successCallback($client)
 {
 $attributes = $client->getUserAttributes();
 // user login or signup comes here
 }
}

登录后复制

在登录的Views中，增加如下代码

<?= yii\authclient\widgets\AuthChoice::widget([
 &#39;baseAuthUrl&#39; => [&#39;site/auth&#39;]
])?>

登录后复制

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;
/**
 *
 * ~~~
 * &#39;components&#39; => [
 * &#39;authClientCollection&#39; => [
 *  &#39;class&#39; => &#39;yii\authclient\Collection&#39;,
 *  &#39;clients&#39; => [
 *  &#39;qq&#39; => [
 *   &#39;class&#39; => &#39;common\components\QqOAuth&#39;,
 *   &#39;clientId&#39; => &#39;qq_client_id&#39;,
 *   &#39;clientSecret&#39; => &#39;qq_client_secret&#39;,
 *  ],
 *  ],
 * ]
 * ...
 * ]

class QqOAuth extends OAuth2
{
 public $authUrl = &#39;https://graph.qq.com/oauth2.0/authorize&#39;;
 public $tokenUrl = &#39;https://graph.qq.com/oauth2.0/token&#39;;
 public $apiBaseUrl = &#39;https://graph.qq.com&#39;;
 public function init()
 {
 parent::init();
 if ($this->scope === null) {
  $this->scope = implode(&#39;,&#39;, [
  &#39;get_user_info&#39;,
  ]);
 }
 }
 protected function initUserAttributes()
 {
 $openid = $this->api(&#39;oauth2.0/me&#39;, &#39;GET&#39;);
 $qquser = $this->api("user/get_user_info", &#39;GET&#39;, [&#39;oauth_consumer_key&#39;=>$openid[&#39;client_id&#39;], &#39;openid&#39;=>$openid[&#39;openid&#39;]]);
 $qquser[&#39;openid&#39;]=$openid[&#39;openid&#39;];
 return $qquser;
 }
 protected function defaultName()
 {
 return &#39;qq&#39;;
 }
 protected function defaultTitle()
 {
 return &#39;Qq&#39;;
 }
 /**
 * 该扩展初始的处理方法似乎QQ互联不能用，应此改写了方法
 * @see \yii\authclient\BaseOAuth::processResponse()
 */
 protected function processResponse($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(&#39;Unable to determine response content type automatically.&#39;);
       }
       $response = $this->processResponse($rawResponse, $contentType);
       break;
     }
     case self::CONTENT_TYPE_JSON: {
       $response = Json::decode($rawResponse, true);
       if (isset($response[&#39;error&#39;])) {
         throw new Exception(&#39;Response error: &#39; . $response[&#39;error&#39;]);
       }
       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(&#39;Unknown response type "&#39; . $contentType . &#39;".&#39;);
     }
   }
   return $response;
 }
}

登录后复制

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

&#39;components&#39; => [
 &#39;authClientCollection&#39; => [
   &#39;class&#39; => &#39;yii\authclient\Collection&#39;,
   &#39;clients&#39; => [
     &#39;qq&#39; => [
      &#39;class&#39;=>&#39;common\components\QqOAuth&#39;,
      &#39;clientId&#39;=>&#39;your_qq_clientid&#39;,
      &#39;clientSecret&#39;=>&#39;your_qq_secret&#39;
    ],
   ],
 ]
]

登录后复制

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。
}

登录后复制

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>
