How to send multiples of same param name with RestClient

HFCDev

I've discovered what I believe is a shortcoming of the RestClient drop-in. If you're POSTing to a service which responds to multipart-form-data requests, then they may expect you to send multiples, for instance in the equivalent GET, how would you manage something like

http://restservice/api/endpoint?input=firstOne&input=secondOne&input=thirdOne?

In my case I'm writing to a service that is expecting multipart form data. I know that RestClient.Post() can take an optional multipart args param, but it, like the params, is an Assoc, so if you have an assoc with a key input, there can be only one.

I know more modern REST APIs would expect input to be passed as a JSON array in this example, i.e. ?input=['firstOne','secondOne','thirdOne'] but that is not an option in this case.

In the past, we managed this using apache http client library, which allowed adding multipart entities for each of the multiples. We moved to RestClient so that we would let OpenText Content Server drive trusted certificates and such.

Am I mistaking this or is this any closer to sending File information using multipart as per the RFC so long as you create the boundary correctly shouldn't a webserver accept it?

In the Creation of a Document/Version we usually supply a contorted version of a multipart but my guess is the receiving OT code is looking for a multipart that says body, name,file, and so on… so they are already processing that.
