REST JSON List Parameters

[userbobParticipant]

Hi,

I am posting/getting a request using the dataadapter.

This data entry needs to be a some kind of array to be picked up by a restful java service at the back end which looks like this

	@GET
	@Path("/messageType")
	public SimpleValueList<String> get(@QueryParam("receiverCode") List<String> receiverCode, @QueryParam("senderCode") List<String> senderCode) {
		return new SimpleValueList<String>(data.getMessageTypes(receiverCode, senderCode));
	}

You can ignore the return type and so on, the important piece is the query param

If I have this on the send then it works for one value

	source = {
	    url : '/messageType',
	    type : 'GET',
	    datatype : 'json',
            contentType: 'application/json',
            data : {
                   'receiverCode' : 'a',
                   'senderCode' : 'b'
            }
	    datafields : [ {
		name : 'value'
	    } ]
	};

I can get it to sort of work with the following on the data

‘receiverCode’ : $.param([{name : ‘receiverCode’, value : ‘5016237030227’},{name : ‘receiverCode’, value : ‘5012648000002’}]),
‘senderCode’ : $.param([{name : ‘senderCode’, value : ‘5016237030227’},{name : ‘senderCode’, value : ‘5012648000002’}])

However when inspecting the list on the server i get one entry in each list which contains the following

[receiverCode=5016237030227&receiverCode=5012648000002]

I appreciate this is probably at the jquery level but can you give me a hint?

Regards,

Richard

Hi Richard,

This should not work. Your data object is expected to be a JSON object or String. jQuery will turn your JSON object to String using $.param, but on your side, it seems that you try to do it twice for some reason. It’s however, not necessary.

Hi thanks for the reply so for me to receive a list on the server side would I have to do this?

data : {
                   'receiverCode' : ['a','b'],
                   'senderCode' : ['1','2']
            }

I have tried every combination now, moving from GET to POST and trying to get a list to show up on the server

If I use Postman then this is perfectly acceptable

["5016237030227","5016237030227"]

However I cannot seem to get the following to work

data = ["5016237030227", "5012648000002"]; 

which results in a payload (for POST) of

0=5016237030227&1=5012648000002

Or

data = {loggedInAs:["5016237030227", "5012648000002"]}

which results in a payload of

loggedInAs%5B%5D=5016237030227&loggedInAs%5B%5D=5012648000002

in other words it puts the [] after each entry?

Thanks for your assistance but this is driving me insane, I can only assume it is all due to various uses of traditional and the $.param functions

[userbobParticipant]

I finally got this working by overriding the underlying ajax component to parse params traditionally

        $.ajaxSetup({
           traditional:true
        });

This puts out the json on the params as I expected and as RESTEasy required

loggedInAs=5055037200003&loggedInAs=5015715444440&loggedInAs=5016237030227

The data call was like this where loggedInAs

data = {'loggedInAs' : ['somevalue', 'somevalue2']}

I hope this helps someone as I spent a couple of days on this very very minor issue
