Тема: How to obtain the number of units in a geofence

Hello,

I am trying to obtain the number of units in each geofence, I have tried with this code github.com/ashmigelski/units-inside however when calculating the units in the geofence with the position of the unit it generates a type 5 error.

I am doing it with the javascript api, I would really appreciate if you can help me.

Re: How to obtain the number of units in a geofence

nmdl hello, the code example from GitHub uses old authorization method.
Login request with username and password was deprecated, so the following function will not work:

wialon.core.Session.getInstance().login(uname, pass, "", loginCallback);

The login request should be performed with token only and following request:

wialon.core.Session.getInstance().loginToken(token, loginCallBack)

The error 5 usually means - Error performing request
So the issue might be related to the network connection.

If the issue persists, please, send your request with the detailed task description to support@wialon.com

Hello zant,

Thanks for the response, I was managing the login with the new method, however it always gave me error 5, I discovered that in order to obtain the number of units in each geofence I must make a call to the wialon.util.Helper method. getZonesInPoint for each unit passing all geofences, here is the code

if (pos && pos.x && pos.y) {
        wialon.util.Helper.getZonesInPoint(
          {
            zoneId: zoneId,
            lat: pos.y,
            lon: pos.x
          },
          function (code, data) {}
        )

The zoneId is a json with all resources. But this method is very heavy and slow, I would like to know if there is any way to make it more agile and faster.

nmdl hello,if you don't need online data, you may try to use reports. You may create a report with Geofences table type, and generate it via API.
If you need any additional details, feel free to write to support@wialon.com and provide details about the task.
