registration\u idto注册id事实上，这个问题似乎是因为U键的崩溃 情景： 我在一个小的时间框架（1分钟）内发送20次推送，使用一些折叠键。 所有这些消息都由设备接收（因为它是在线的）。 当我尝试发送新推送时，只会收到最后一个推送，而这恰好发生在3分钟后（超过20次推送限制后）。 因此，该设备能够每3分钟接收一次推送 此问题仅在使用折叠键时发生。如果我不使用折叠键，那么似乎没有限制。
在某些情况下，计数会重置，例如当设备重新启动或网络发生变化时。实际上，问题似乎是因为密钥崩溃 情景： 我在一个小的时间框架（1分钟）内发送20次推送，使用一些折叠键。 所有这些消息都由设备接收（因为它是在线的）。 当我尝试发送新推送时，只会收到最后一个推送，而这恰好发生在3分钟后（超过20次推送限制后）。 因此，该设备能够每3分钟接收一次推送 此问题仅在使用折叠键时发生。如果我不使用折叠键，那么似乎没有限制。
