如何在Spyne中设置端口的名称和绑定？

from spyne import Application, rpc, ServiceBase

class MyService(ServiceBase):
    __port_name__ = 'MyPort'

    @rpc()
    def my_method(self):
        pass

application = Application([MyService], 'my_namespace')

from spyne import Application, rpc, ServiceBase

class MyService(ServiceBase):
    __service_name__ = 'MyService'

    @rpc()
    def my_method(self):
        pass

application = Application([MyService], 'my_namespace')
