Windchill RV+S - Use trigger script to call an external RestAPI webservice

Hi all,

my problem seems to be sooo simple, yet I struggle with the details.

The GOAL:

- implement an one way interface between PTC RV&S (12.3 ++) and an external webservice that offers a RestAPI ("fire & forget")

Approach:

- a rule based post event trigger shall fire in case the PTC item reaches a certain state.

- the custom JS trigger script transfer the ID of a PTC item to an external webservice as follows:

1. prepare the POST message containing the ID as a JSON format

2. sends the data to a (hardcoded) URL

3. receive the response and log success OR error

The PROBLEM:

- inside the custom JS trigger code step 1 is easy, but the actual sending of the POST request seams to be extremely tricky

I tried to use the

mks.frame.triggers.beans.ScriptProcessBuilderBean - to create a

mks.frame.triggers.beans.ScriptProcessBean - that should run a CURL command performing the actual webrequest

As this did not work I tried a PowerShell process, using a one-line script for the required actions.

Unfortunately the

mks.frame.triggers.beans.ScriptProcessBean does allow me use it's OutputStream

public java.io.OutputStream getOutputStream()

but somehow this does not work for me 😞

Can anyone provide me a working sample on how to access the Output of the ScriptProcessBean in a trigger script?

Or even better, does anyone have any idea how I can make my webrequest without the ScriptProcessBean?
