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' => 'yiiauthclientcollection', 'clients' => [ 'google' => [ 'class' => 'yiiauthclientclientsgoogleopenid' ], 'facebook' => [ 'class' => 'yiiauthclientclientsfacebook', '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' => 'yiiauthclientauthaction',
'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
<?= yiiauthclientwidgetsauthchoice::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
<?php
namespace commoncomponents;
use yiiauthclientoauth2;
use yiibaseexception;
use yiihelpersjson;
/**
*
* ~~~
* 'components' => [
* 'authclientcollection' => [
* 'class' => 'yiiauthclientcollection',
* 'clients' => [
* 'qq' => [
* 'class' => 'commoncomponentsqqoauth',
* '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 $qquser;
}
protected function defaultname()
{
return 'qq';
}
protected function defaulttitle()
{
return 'qq';
}
/**
* 该扩展初始的处理方法似乎qq互联不能用，应此改写了方法
* @see yiiauthclientbaseoauth::processresponse()
*/
protected function processresponse($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 $response;
}
}
更改 config/main.php 文件，在components中增加，大致如下
'components' => [
'authclientcollection' => [
'class' => 'yiiauthclientcollection',
'clients' => [
'qq' => [
'class'=>'commoncomponentsqqoauth',
'clientid'=>'your_qq_clientid',
'clientsecret'=>'your_qq_secret'
],
],
]
]
sitecontroller.php 就按官方那样子
public function successcallback($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>
