我试图从JSON API中获取图像，我在开放数据JSON中做了两个链接，在此链接：http://www.json-generator.com/api/json/get/bOEcLwbyqa?indent=2
错误：另一个异常被抛出：HttpException：Connection closed while receiving data，uri =
对于“picturep”它工作（第一个屏幕截图），但对于“picture”它不工作（第二个屏幕截图），
我正在使用CicleAvatar与网络图像：

leading:CircleAvatar(
          backgroundImage: NetworkImage(user.picturep),
    ),
