Transferring Axeda Agent Uploaded Files to Thingworx

No ratings

The following is a set of custom objects that will trigger from an Expression Rule, and cause a file uploaded by a remote agent to be sent on to the Thingworx platform instance of your choice once completed.  The expression rules should be configured as so:

  • ​Type: ​File
  • ​IF: ​1 == 1
  • ​THEN: ​ExecuteCustomObject("SendUploadedFiles")


SendUploadedFiles.groovy:

import com.axeda.drm.sdk.data.UploadedFile

import static com.axeda.sdk.v2.dsl.Bridges.*

logger.info("Executing AsyncExecutor")

//Spawn async thread for each upload

compressedFile.getFiles().each {

  UploadedFile upFile ->

    // last parameter is a timeout for the execution measured in seconds (200 minutes)

    customObjectBridge.initiateAsync("SendToThingWorx",

                                    [

                                      fileID: upFile.id,

                                      hint: parameters.hint,

                                      deviceID: context.device.id

                                    ], 200 * 60)

}
