Description

1.之前的接口GetCurrentData是通过遍历实时库来获取所有的点数据,比较耗时;
2.改为新接口GetRdbPointData(clientId, PointInfo)可以实现对所有点的订阅,
如果点变化,才在客户端请求时,回复给客户端变化的点数据;减少了对实时库
的低效和大量遍历。

逻辑过程:
web客户端连上ISDataServer后,发送"自身ID+全量点"包给服务端,服务端回复所有全量点包的状态,value等字段给web;
后续如果页面不切换,则web客户端每隔1s发送"自身ID+空包"给服务端,服务端根据变化的点进行组包并回复web。如果web
的页面进行了切换,则继续上述逻辑。
