生成场景二维码前提：

微信的场景二维码性能次要是生成一个微信二维码，而后在手机应用微信扫描此二维码时，会触发微信告诉，所以咱们在生成场景二维码之前进行微信的服务端验证

1：服务端验证

$app = Yii::$app->wechat->getApp();  $server = $app->server;  $response = $server->serve();  $response->send();  exit();

服务端验证代码实现之后在微信公众号进行服务端验证即可

2：生成场景二维码

$app = Yii::$app->wechat->getApp();$app->server->push(function ($message) use ($app) {    switch ($message['MsgType']){        case 'event':        //扫码事件：SCAN 订阅事件：subscribe            if (isset($message['Event']) && ($message['Event'] == 'SCAN' || $message['Event'] == 'subscribe')) {                $openId = $message['FromUserName'];//扫面用户的openID                //获取参数                if ($message['Event'] == 'SCAN') {                    $code= $message['EventKey'];                } else {                    $code= str_replace('qrscene_', '', $message['EventKey']);                }            //发送图文音讯                $items = [                    new NewsItem([                        'title'=> '图文题目',                        'description' => '图文形容',                        'url' => '图文链接',                        'image'=> '图文图片,                    ]),                ];                return new News($items);            }            break;        default:            break;    }});$server = $app->server;$response = $server->serve();$response->send();exit();

依据如上就能够实现场景二维码
