你也可以使用相同的android

purgeOutstandingWrites

Firebase数据库客户端会自动对写入进行排队,并尽早将其发送到服务器,具体取决于网络连接. In some cases (e.g. offline usage) there may be a large number of writes waiting to be sent. Calling this method will purge all outstanding writes so they are abandoned.

All writes will be purged, including transactions and onDisconnect() writes. The writes will be rolled back locally,可能会触发受影响事件侦听器的事件,并且客户端不会(重新)将它们发送到Firebase后端.
