使用Geofire集传输多少数据 [英] How much data is transferred with geofire set

问题描述

当我使用以下命令将位置发送到geofire表时，传输了多少数据 geoFire.set("?????", [??.????, ??.????])在建立浏览器客户端的连接之后?

How much data is transferred when I send the location to geofire table with geoFire.set("?????", [??.????, ??.????]) after the connection of the browser client has be set up?

• Somekey是最多5位数字的唯一ID?
• 下降到第4位(根据测量，我们的精度为11m经纬度的精度)

我们想向公共交通运输中的车队展示的客户实际上并没有那么多-但想提供事实.每5-10秒获取一次数据会很好.

We want to show a client with a fleet in public transport that it isn't really that much - but want to give facts. It would be nice to get the data every 5-10 seconds.

推荐答案

要查看正在传输多少数据:

To see how much data is being transferred:

• 打开浏览器的网络"标签
• 选择 WS 面板以仅查看Web套接字
• 找到连接到Firebase服务器的Web套接字
• 检查设置值和确认的框架的大小

• open the network tab of your browser
• select the WS panel to just see web sockets
• find the web socket that connects to your Firebase server
• check the size of the frame that sets the value and the acknowledgement

第一个GeoFire javascript示例的一个示例:

{"t":"d","d":{"r":2,"a":"m","b":{"p":"/-Kcj5Z0QMWqWaqO-3bUk","d":{"fish0":{".priority":"rmjhprs42j","g":"rmjhprs42j","l":[-16.130262,153.605347]}}}}}
