Question

下面的代码片段来自actuator agent，我正在尝试研究方法revert_point：

#@RPC.export
def revert_point(self, requester_id, topic, point=None, **kwargs):
    """
    RPC method
    
    Reverts the value of a specific point on a device to a default state. 
    Requires the device be scheduled by the calling agent.
    
    :param requester_id: Ignored, VIP Identity used internally
    :param topic: The topic of the point to revert in the 
                  format <device topic>/<point name>
    :param \*\*kwargs: Any driver specific parameters
    :type topic: str
    :type requester_id: str
    
    .. warning:: Calling without previously scheduling a device and not
    within
                 the time allotted will raise a LockError"""

    rpc_peer = self.vip.rpc.context.vip_message.peer
    return self._revert_point(rpc_peer, topic, point=point, **kwargs)

我称revert_point：

for device in revert_topic_devices:
    response = self.vip.rpc.call('platform.actuator', 'revert_point', self.core.identity, final_topic, self.jci_setpoint_topic).get(timeout=3)

此信息：

2.0 (self.core.identity) 
slipstream_internal/slipstream_hq/27/OCC-SCHEDULE (final_topic)
2.0
slipstream_internal/slipstream_hq/29/OCC-SCHEDULE
2.0
slipstream_internal/slipstream_hq/30/OCC-SCHEDULE

我收到一个关键错误：

volttron.platform.jsonrpc.RemoteError: volttron.platform.jsonrpc.RemoteError("builtins.KeyError('slipstream_internal/slipstream_hq/30/OCC-SCHEDULE')")

Answer 1

我想通了，像这样调用方法：

for device in revert_topic_devices:
    response = self.vip.rpc.call('platform.actuator', 'revert_point', self.core.identity, topic, self.jci_setpoint_topic).get(timeout=3)

主题应如下所示：

slipstream_internal/slipstream_hq/27
2.0
slipstream_internal/slipstream_hq/29
2.0
slipstream_internal/slipstream_hq/30

VOLTTRON 执行器代理 revert_point
