This is related to and sort of a followup on this question
I need to know how I can pass and receive arguments to a Web API REST method.
I believe the way I am passing the args from the Client is correct, namely:
http://localhost:28642/api/InventoryItems/PostInventoryItem?ID=42?pksize=12?Description=ValuableDesc?vendor_id=venderado?dept=42?subdept=85?UnitCost=2.50?UnitList=3.75?OpenQty=25.25?UPC=12345?upc_pack_size=24?vendor_item=someVendorItem?crv_id=9898987
...where the first part:
http://localhost:28642/
...is the machine and port; the second part:
/api/InventoryItems/PostInventoryItem
...indicates the Controller and its method to run, and the final part (the rest) are the individual args to pass (in the format "?=").
Based on what is written here, namely:
"The method takes a parameter of type Product. In Web API, parameters with complex types are deserialized from the request body. Therefore, we expect the client to send a serialized representation of a product object, in either XML or JSON format."
...I was hoping that I could use this on my Controller:
[Route("api/InventoryItems/PostInventoryItem")]
public HttpResponseMessage PostInventoryItem(InventoryItem ii)
{
_inventoryItemRepository.PostInventoryItem(ii.ID, ii.pksize, ii.Description, ii.vendor_id, ii.dept,
ii.subdept, ii.UnitCost, ii.UnitList, ii.OpenQty, ii.UPC, ii.upc_pack_size, ii.vendor_item, ii.crv_id);
// If/when this works, could do this instead:
//_inventoryItemRepository.PostInventoryItem(ii);
var response = Request.CreateResponse<InventoryItem>(HttpStatusCode.Created, ii);
string uri = Url.Link("DefaultApi", new { id = ii.ID });
response.Headers.Location = new Uri(uri);
return response;
}
...and that the client batch of args would get automatically bundled up into an InventoryItem object; but, alas, Web API is not able to do so (or I did something wrong/have as yet failed to do something right) and ii is null when the method is reached.
Do I have to do it different on the sending side, or on the receiving side, or both? What, exactly, do I need to amend or append?
UPDATE
If I try this instead in the Controller:
public HttpResponseMessage PostInventoryItem(string id, int pack_size, string description, string vendor_id, int department, int subdepartment, double unit_cost, double unit_list, double open_qty, string UPC_code, int UPC_pack_size, string vendor_item, long crv_id)
{
_inventoryItemRepository.PostInventoryItem(id, pack_size, description, vendor_id, department, subdepartment,
unit_cost, unit_list, open_qty, UPC_code, UPC_pack_size, vendor_item, crv_id);
InventoryItem ii = new InventoryItem();
ii.ID = id;
ii.pksize = pack_size;
. . .
ii.crv_id = (int)crv_id;
var response = Request.CreateResponse<InventoryItem>(HttpStatusCode.Created, ii);
...with a breakpoint on the "_inventoryItemRepository.PostInventoryItem()" line, it doesn't reach it, and the client, on attempting to send the URI to the server, pops up a message box that simply says, "null."
UPDATE 2
A combination of changing the Controller signature to this:
public HttpResponseMessage PostInventoryItem([FromUri] InventoryItem ii)
(hat's off to Mike Wasson for his article here)
...and (kudos to the wealthy beast of burden (richaux)) replacing all but the first "?" with "&":
http://localhost:28642/api/InventoryItems/PostInventoryItem?ID=42&pksize=12&Description=ValuableDesc&vendor_id=venderado&dept=42&subdept=85&UnitCost=2.50&UnitList=3.75&OpenQty=25.25&UPC=12345&upc_pack_size=24&vendor_item=someVendorItem&crv_id=9898987
...did the trick.
