yii2中QQ第三方登录网站

​​

1、先注册成为开发者，并实名认证。https://connect.qq.com

2、创建应用。​​https://connect.qq.com/manage.html#/appcreate/web​​（回调域名一般是自己的主域名）

3、应用审核成功后，获取appid appkey

4、下载QQ登录的php SDK。​​http://wiki.connect.qq.com/sdk%E4%B8%8B%E8%BD%BD​​

5、将下载的文件解压后放到WEB目录下，访问install/index.php文件。然后只保留API文件夹的内容 ，其余全部删掉。将API重命名为qqlogin放入到vendor目录。（install步骤会自动更改配置，如果未生效，则手动修改qqlogin\comm\inc.php）

{"appid":"*****","appkey":"******","callback":"http://www.****.com/index.php?r=member/qqcallback","scope":"get_user_info,add_share,list_album,add_album,upload_pic,add_topic,add_one_blog,add_weibo,check_page_fans,add_t,add_pic_t,del_t,get_repost_list,get_info,get_other_info,get_fanslist,get_idolist,add_idol,del_idol,get_tenpay_addr","errorReport":true,"storageType":"file","host":"localhost","user":"root","password":"root","database":"test"}

6、U//serController控制器配置

//进入QQ登录界面
    public function actionQqlogin(){
        require_once("../vendor/qqlogin/qqConnectAPI.php");
        $qc = new \QC();
        $qc->qq_login();
    }
    
    //执行qq_login方法后，获取用户信息后的回调地址中的操作
    public function actionQqcallback(){
        require_once("../vendor/qqlogin/qqConnectAPI.php");
        $auth = new \OAuth();
        $accessToken = $auth->qq_callback();
        $openid = $auth->get_openid();
        $qc = new \QC($accessToken, $openid);
        $userinfo = $qc->get_user_info();
        $session = Yii::$app->session;
        $session['userinfo']= $userinfo;
        $session['openid']=$openid;
        //如果openid存在，则把账号信息写入session
        if(User::find()->where('openid=:openid',[':openid'=>$openid])->one()){
            $session['loginname']=$userinfo['nickname'];
            $session['isLogin']=1;
            return $this->redirect(['index/index']);
        }
        //如果openid不存在，则绑定账号信息
        return $this->redirect(['member/qqreg']);
        //var_dump($userinfo);
    }
    public function actionQqreg(){
        $this->layout='layout2';
        $model = new User;
        if(Yii::$app->request->isPost){
            $post = Yii::$app->request->post();
            $session=Yii::$app->session;
            $post['User']['openid']=Yii::$app->session['openid'];
            //var_dump($post);
            if($model->reg($post, 'qqreg')){
                $session['loginname']=$session['userinfo']['nickname'];
                $session['isLogin']=1;
                return $this->redirect(['index/index']);
            }
            //var_dump($model->getErrors());
        }
        return $this->render('qqreg',['model'=>$model]);
    }
