When an Expression Rule of type MobileLocation calls a Groovy script, the script is provided with the implicit object mobileLocation. This example shows how the mobileLocation object can be used.
This Expression Rule calls the Groovy script 'getAddress' to retrieve the location and translate it into a street address:
Type: MobileLocation IF: some condition e.g. true THEN: SetDataItem("location", str(ExecuteCustomObject("getAddress"))) |
The 'getAddress' script uses the mobileLocation object to retrieve the asset's reported location, and then calls a REST service to translate a given latitude and longitude to a street address. The street address is returned.
import groovyx.net.http.RESTClient
String rmdHostname = "http://ws.geonames.org";
if (mobileLocation != null)
{
rmd = new RESTClient(rmdHostname);
try {
def resp = rmd.get( path: 'findNearestAddress',
query:[lat:mobileLocation.lat , lng:mobileLocation.lng] )
streetnum = resp.data.address.streetNumber.text()
street = resp.data.address.street.text()
town = resp.data.address.adminName2.text()
state = resp.data.address.adminCode1.text()
postalcode = resp.data.address.postalcode.text()
return streetnum + " " + street + " " + town + " " + state + " " + postalcode
} catch (groovyx.net.http.HttpResponseException e) {
e.printStackTrace();
}
}
