WebApi2如何通过数组传递Json

Question

I have the following Json with array that I am sending it from AngularJS

{id_fleet: 4177, id_fleetfeature: Array[2]}

var dataFeatures = {
    id_fleet: $scope.id,
    id_fleetfeature: $scope.selectedFeatures
}
$http.put(myUrl + "Fleets/Insert", JSON.stringify(dataFeatures)).then(function () {
    Materialize.toast('Features insertadas correctamente', 3000);
    $scope.refreshData();
});

Web API Model

public class modelFleetFeatures {
    public int id_fleet { get; set; }
    public int[] id_fleetfeature { get; set; }
}

Web API Function

[HttpPut]
[Route("api/Fleets/FleetFeature/Update")]
public HttpResponseMessage updateFleetFeature(List<modelFleetFeatures> data)
{
    var cnt = 0;

    foreach (var item in data)
    {
        db.sp_Fleet_FleetFeaturesDelete(item.id_fleet);
        db.SaveChanges();
    }

    foreach (var item in data)
    {
        db.sp_Fleet_FleetFeaturesInsert(item.id_fleet, item.id_fleetfeature[cnt]);
        db.SaveChanges();
        cnt +=1;
    }

    return new HttpResponseMessage { StatusCode = HttpStatusCode.OK };
}

In the Web API the value of data always gets null

Answer 1

You are sending single object in JSON, so why expecting list of object in API action? Just expect single object in api Action , you will get that object model in call like :

public HttpResponseMessage updateFleetFeature(modelFleetFeatures data)
{
    //do stuff
}

And no need to stringify json object in put request.

$http.put(myUrl + "Fleets/Insert", dataFeatures).then(function () {
    Materialize.toast('Features insertadas correctamente', 3000);
    $scope.refreshData();
});
