本文实例讲述了Yii2中OAuth扩展及QQ互联登录实现办法.分享给大家供大家参考,具体如下：
PHP实战
Quick start 快速开始PHP实战
更改Yii2的配置文件config/main.php,在components中增加如下内容PHP实战
'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增加代码,同时增加回调函数successCallback,大致如下PHP实战
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
}
}
在登录的Views中,增加如下代码PHP实战
<?= yii\authclient\widgets\AuthChoice::widget([ 'baseAuthUrl' => ['site/auth'] ])?>
以上是官方的说明文档,下面我们来接入QQ互联PHP实战
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实战
<?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/
*
* @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 $qquser;
}
protected function defaultName()
{
return 'qq';
}
protected function defaultTitle()
{
return 'Qq';
}
/**
* 该扩展初始的处理办法似乎QQ互联不能用,应此改写了办法
* @see \yii\authclient\BaseOAuth::processResponse()
*/
protected function processResponse($rawResponse, $contentType = self::CONTENT_TYPE_AUTO)
{
if (empty($rawResponse)) {
return [];
}
switch ($contentType) {
case self::CONTENT_TYPE_AUTO: {
$contentType = $this->determineContentTypeByRaw($rawResponse);
if ($contentType == self::CONTENT_TYPE_AUTO) {
//以下代码是特别针对QQ互联登录的,也是与原办法不一样的地方
if(strpos($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 $response;
}
}
更改 config/main.php 文件,在components中增加,大致如下PHP实战
'components' => [
'authClientCollection' => [
'class' => 'yii\authclient\Collection',
'clients' => [
'qq' => [
'class'=>'common\components\QqOAuth',
'clientId'=>'your_qq_clientid',
'clientSecret'=>'your_qq_secret'
],
],
]
]
SiteController.php 就按官方那样子PHP实战
public function successCallback($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PHP实战
<a href="/site/auth?authclient=qq">使用QQ快速登录</a>
