用户通过扫带参数的二维码关注公众号，公众号推送数据的参数里Event是subscribe，但EventKey并没有包含扫码的参数，subscribe_scene应该是ADD_SCENE_QR_CODE，但是会出现ADD_SCENE_SEARCH，ADD_SCENE_OTHERS，ADD_SCENE_CHANNELS，也会出现ADD_SCENE_QR_CODE，但是EventKey依旧是空 appid：wxb87912b1166eef72 带参数二维码： [图片] 公众号返回扫码关注数据，EventKey为空，无返回参数： 2022-11-24 12:45:22 'data' =>    array (     'ToUserName' => 'gh_efc77ca8c7ac',     'FromUserName' => 'omt27uIB29DuyyxaTsmN_PKIGhhM',     'CreateTime' => '1669265121',     'MsgType' => 'event',     'Event' => 'subscribe',     'EventKey' => NULL,   ) 通过FromUserName获取客户数据 array (     'subscribe' => 1,     'openid' => 'omt27uIB29DuyyxaTsmN_PKIGhhM',     'nickname' => '',     'sex' => 0,     'language' => 'zh_CN',     'city' => '',     'province' => '',     'country' => '',     'headimgurl' => '',     'subscribe_time' => 1669265121,     'unionid' => 'oAndb6fB9q-tmv2wxiDVQmDBJ7rs',     'remark' => '',     'groupid' => 0,     'tagid_list' =>      array (     ),     'subscribe_scene' => 'ADD_SCENE_SEARCH',     'qr_scene' => 0,     'qr_scene_str' => '',     'app_id' => 'wxb87912b1166eef72',   ) 同一个用户重新识别二维码，成功返回，2022-11-24 12:45:50 array (     'ToUserName' => 'gh_efc77ca8c7ac',     'FromUserName' => 'omt27uIB29DuyyxaTsmN_PKIGhhM',     'CreateTime' => '1669265150',     'MsgType' => 'event',     'Event' => 'SCAN',     'EventKey' => 'id_user=50022&bra_id=284&from_type=wx',     'Ticket' => 'gQFM8TwAAAAAAAAAAS5odHRwOi8vd2VpeGluLnFxLmNvbS9xLzAyRk5LWFY2cXRhWFUxMDAwMHcwN0cAAgTy8stiAwQAAAAA',   ) 能帮忙跟进处理下么，这种情况特别多

公众号生成带参数二维码，采用{"action_name": "QR_LIMIT_STR_SCENE", "action_info": {"scene": {"scene_str": "test"}}}格式，步骤如下： 1、POST https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token={0}，获取到{"ticket":"gQGi8TwAAAAAAAAAAS5odHRwOi8vd2VpeGluLnFxLmNvbS9xLzAyUU82bG8wdkhmREQxeGkzczFBMUwAAgTSyJJkAwSAOgkA","expire_seconds":604800,"url":"http://weixin.qq.com/q/02QO6lo0vHfDD1xi3s1A1L"} 2、通过ticket换取二维码 GET https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket=gQGi8TwAAAAAAAAAAS5odHRwOi8vd2VpeGluLnFxLmNvbS9xLzAyUU82bG8wdkhmREQxeGkzczFBMUwAAgTSyJJkAwSAOgkA 以上两个步骤都成功，扫描scene_str值不一样的二维码图片，后台接收到的信息一样，且没有看到参数scene_str，如下： <xml><ToUserName><![CDATA[gh_34cc79c09e6c]]></ToUserName> <FromUserName><![CDATA[on2vn59fH3FvhZZPNG_YvUzJEENk]]></FromUserName> <CreateTime>1687340674</CreateTime> <MsgType><![CDATA[event]]></MsgType> <Event><![CDATA[SCAN]]></Event> <EventKey><![CDATA[0]]></EventKey> <Ticket><![CDATA[gQGD8DwAAAAAAAAAAS5odHRwOi8vd2VpeGluLnFxLmNvbS9xLzAyckJOdm9FdkhmREQxSkM3aWhBMXMAAgQ6xpJkAwQsAQAA]]></Ticket> </xml> 请指导下，问题出在哪里？另外第一个步骤里获取到的url，开发者可根据该地址自行生成需要的二维码图片，指导下如何自行生成，谢谢。
