微信公众服务号带参数二维码回调参数：EventKey值是0，不是设定的场景值？
$params = '{"action_name": "QR_LIMIT_SCENE", "action_info": {"scene": {"scene_id": 123}}}';
通过CURL:post方式提交过去，但是回调EventKey返回值 = 0；
返回值打印出来的：EventKey:0 - openId:oaOia001BKI9rbZOxoyOrU_CPY18
这是回调接收到的值
{"ToUserName":"gh_9e86e4d",
"FromUserName":"oaOia001BKIbZY18",
"CreateTime":"1598507911",
"MsgType":"event",
"Event":"SCAN",
"EventKey":"0",
"Ticket":"gQHJ8DwAAAAAAAAAAS5odHRwOi8vxMDAwMGcwMzMAAgRmlj9fAwQAAAAA"}
誰遇到过同类的问题，能麻烦帮忙解答一下吗
