菜单拍照获取不到图片信息

自己创建的菜单，通过拍照和相册功能上传图片，测试环境我用小图测试，可以得到图片的信息，大图就不可以。正式环境小图大图都获取不到图片信息。求高手指点~

获取到的结果如下：

您点击了菜单中的拍照：rselfmenu_text

{ ToUserName: 'gh_31aa3573f70b',

  FromUserName: 'oG1ORt-gFiWNVFxXW5rKewNNZrwk',

  CreateTime: '1509933031',

  MsgType: 'event',

  Event: 'pic_photo_or_album',

  EventKey: 'rselfmenu_text',

  SendPicsInfo: { Count: '0', PicList: '' } }

replay代码

else if(message.EventKey === 'rselfmenu_car'){
    console.log('rselfmenu_car');
    this.body = '您点击了菜单中的拍照：' + message.EventKey
    console.log('您点击了菜单中的车拍照：' + message.EventKey);
    console.log(message);
    console.log(message.SendPicsInfo.PicList);

menu代码
