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

'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

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
?

<?= 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
增加QQ登录的组件 我这里是放在 common/components/QqOAuth.php 中，源代码如下

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

'components' => [

'clients' => [
'qq' => [
'class'=>'common\\components\\QqOAuth',
'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?authclient=qq">使用QQ快速登录</a>

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
