Best way to pass parameters to a service

edit

@dornhege Ok, I was actually a little bit confused. So, I would like to allow the user to pass parameters as part of the service call, so that he can run the service once and make some trials calling it with different parameters. But how do I do this?

In that case, just add the parameters to the service request.

So I have to add them to the service request? But I think in this case they become necessary, while I'd like to have a series of optional parameters, that the user can decide to pass or not..

A service request is always the full struct. However, you can define some values to be "undefined" and handle those correctly.

But in this way the user should set to "undefined" all the parameters he doesn't want to use.. Actually I thought about passing only the node handle as a parameter, so that using getParam() I can check which parameters the user decided to pass, but it doesn't seem a very clean solution..

You cannot pass a node handle through a service call. That is a local construct. If those parameters directly influence the return value of the service, it seems to me that they belong to the request anyways.

Be aware of using parameters and setting them for a request in your way. Parameters are not deleted unless explicitly specified, So if a parameter is not set, it might still have the value of a previous call.

Yeah, but I don't want to force the user to insert also unnecessary values. So the two alternatives should be the one you suggested or using the parameter server, so that he can only set on the parameter server only the parameters he needs, right?
