TypeError:调用未绑定方法getInterfaceName（）时必须将接口实例作为第一个参数（改为什么也没有得到）

班级单位： definit（self，_chassisId，_unitNo，_接口）： 自我惩罚=底盘 自身单位编号=单位编号 自我接口=\u接口

类接口： definit（self，_linkState，_接口名）： 自链接状态=\u链接状态 自身接口名=\u接口名

您没有向我们显示导致错误的getInterfaceName()调用，这使您更难帮助您。在

不过，我想电话应该是这样的：

something = Interface.getInterfaceName()

你不能那样做。必须创建Interface的实例，然后调用其.getInterfaceName()方法：
