func DoUploadedPhotoFile ¶

func DoUploadedPhotoFile(src *PhotoFile, extName string, srcData []byte, isABC bool, cb func(pi *PhotoInfo)) error

TODO(@benqi):

	我们未来的图片存储系统可能会按facebook的Haystack论文来实现
	mtproto协议也定义了一套自己的文件存储方案，fileLocation#53d69076 dc_id:int volume_id:long local_id:int secret:long = FileLocation;
	在这里，我们重新定义mtproto的volume_id和local_id，对应Haystack的key和alternate_key，secret对应cookie
 在当前简单实现里，volume_id由sonwflake生成，local_id对应于图片类型，secret为access_hash

TODO(@benqi):

参数使用mtproto.File
