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' => '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
1

'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

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
1
|
<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。
