本文實例講述了Yii2中OAuth擴(kuò)展及QQ互聯(lián)登錄實現(xiàn)方法。分享給大家供大家參考，具體如下：
代碼如下:
php composer.phar require --prefer-dist yiisoft/yii2-authclient "*"
Quick start 快速開始
更改Yii2的配置文件config/main.php，在components中增加如下內(nèi)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增加代碼，同時增加回調(diào)函數(shù)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
}
}
在登錄的Views中，增加如下代碼
<?= yii\authclient\widgets\AuthChoice::widget([
'baseAuthUrl' => ['site/auth']
])?>
以上是官方的說明文檔，下面我們來接入QQ互聯(lián)
增加QQ登錄的組件 我這里是放在 common/components/QqOAuth.php 中，源代碼如下
<?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 $qquser;
}
protected function defaultName()
{
return 'qq';
}
protected function defaultTitle()
{
return 'Qq';
}
/**
* 該擴(kuò)展初始的處理方法似乎QQ互聯(lián)不能用，應(yīng)此改寫了方法
* @see \yii\authclient\BaseOAuth::processResponse()
*/
protected function processResponse($rawResponse, $contentType = self::CONTENT_TYPE_AUTO)
{
if (empty($rawResponse)) {
return [];
}
switch ($contentType) {
case self::CONTENT_TYPE_AUTO: {
$contentType = $this->determineContentTypeByRaw($rawResponse);
if ($contentType == self::CONTENT_TYPE_AUTO) {
//以下代碼是特別針對QQ互聯(lián)登錄的，也是與原方法不一樣的地方
if(strpos($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;
}
//代碼添加結(jié)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 $response;
}
}
更改 config/main.php 文件，在components中增加，大致如下
'components' => [
'authClientCollection' => [
'class' => 'yii\authclient\Collection',
'clients' => [
'qq' => [
'class'=>'common\components\QqOAuth',
'clientId'=>'your_qq_clientid',
'clientSecret'=>'your_qq_secret'
],
],
]
]
SiteController.php 就按官方那樣子
public function successCallback($client)
{
$attributes = $client->getUserAttributes();
// 用戶的信息在$attributes中，以下是您根據(jù)您的實際情況增加的代碼
// 如果您同時有QQ互聯(lián)登錄，新浪微博等，可以通過 $client->id 來區(qū)別。
}
最后在登錄的視圖文件中 增加QQ登錄鏈接
<a href="/site/auth?authclient=qq">使用QQ快速登錄</a>
希望本文所述對大家基于Yii框架的PHP程序設(shè)計有所幫助。
