Multiple Parameter PUT

[sesa237670_brid]

I am using Sample REST Provider Class example to add my SetMode() method. This method takes three parameter RoomNum, mode and ModeChangeTime. I am able to add it in my custom REST Provider class. However, on execution of PUT method, I am getting error - "Can't bind multiple parameters'. Is multiple parameters supported  ? Do I need to add some attribute [MultiPostParameters]  for it to work.  Is it supported in SmartrtConnector ? Please advise.

Hi Neeraj,

This is actually nothing to do with SmartConnector. Programming an API controller is actually just MVC ASP stuff from .NET. As you noticed I don’t think you can have multiple parameters in a PUT request. But you can pass in an object type, instead of a 3 primitives.

See below for an example. The example has multiple URL parameters, and a single body parameter that is actually an object with a Key/Value pair.

#region UpdateValue (PUT)
/// <summary>
/// Updates the property requested to the new value.
/// </summary>
/// <param name="roomId">ID of the Alexa device targeted</param>
/// <param name="action">Action to take</param>
/// <param name="newValue">Property Name/Value pair</param>
[HttpPut, Route("Value/{roomId}/{actionName}"), ResponseType(typeof(string))]
public HttpResponseMessage Update(string roomId, string actionName, [FromBody] NameValue newValue)
{
Func<HttpResponseMessage> method = delegate
{
Func<object, HttpResponseMessage> innerMethod = delegate
{
var roomMapping = Provider.GetRoomMapping(roomId);
if(roomMapping == null) this.ThrowItemNotFoundException("Alexa", roomId);
var ewsId = Provider.GetValueItemId(roomMapping, actionName, newValue.Name);
var valueModel = Provider.UpdateScalarValue<ValueModel>(this, ewsId, "Value", newValue.Value);
var response = Request.CreateResponse(HttpStatusCode.OK, valueModel.Value);
return response;
   };
return this.ExecuteAndLogCall("UpdateValue", new { RoomId = roomId, Action = actionName, NewValue = newValue }, innerMethod);
};
return this.ExecuteRequestAndHandleErrors(method);
}
#endregion

Hi Jeff,

Thanks for the explanation and sample. I am able to pass three parameters using header as in your sample:

//[HttpPut, Route("SetMode"), ResponseType(typeof(string))]

        [HttpPut, Route("SetMode/bValue/{RoomNum}/{Mode}/{ModeChangeTime}"), ResponseType(typeof(string))]

        public HttpResponseMessage SetMode(string RoomNum, string Mode, DateTime ModeChangeTime)

        {

}

I found the issue is with date being passed as '1/1/2018'. It works if I pass date as '1 Jan 2018'.

Thanks Again!
