Client Universall App WebApi

[Paolo Mazzon]

Hello I am trying to load data into a web API with a Universal app, but testing with Fiddler will not come out the data in the correct format This should be the result:

{"IDBusta":4,"NomeCliente":"Fior","Prezzo":9.0}]

instead it comes so:

alue=%7B%22IDBusta%22%3A22%2C%22NomeCliente%22%3A%22fff%22%2C%22Prezzo%22%3A22.0%7D

this is the class on question:

public sealed partial class CreateOrUpdate : Page
{
bool? create { get; set; }
public CreateOrUpdate()
{
this.InitializeComponent();
}

    protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        // Must be a request to update
        // Because if the "create" is null or true, 
        // it is to denote that the request is to create a new object
        if (e.Parameter as bool? == false)
        {
            create = e.Parameter as bool?;
            var busta = App.ActiveBusta;
            TextBoxIdBusta.Text = busta.IDBusta.ToString();
            TextBoxNome.Text  = busta.NomeCliente.ToString();
            TextBoxPrezzo.Text = busta.Prezzo.ToString();

            actionButton.Content = "Update";
        }
    }

    private void Button\_Click(object sender, RoutedEventArgs e)
    {
        if ((sender as Button).Content.ToString() == "Home")
        {
            // Go to default page 
           this.Frame.Navigate(typeof(MainPage));
            return; // and cancel the event.
        }

        // Otherwise
        var busta = new Busta
        {
            IDBusta = Convert.ToInt32(TextBoxIdBusta.Text),
            NomeCliente   = TextBoxNome.Text.ToString(),
            Prezzo = float.Parse(TextBoxPrezzo.Text),
    };

        using (var client = new HttpClient())
        {
            var content = JsonConvert.SerializeObject(busta);

            if (create == null || create == true)
            {
                // Send a POST
                Task task = Task.Run(async () =>
                {
                    var data = new HttpFormUrlEncodedContent(
                        new Dictionary
                        {
                            \["value"\] = content
                        }
                    );
                    await client.PostAsync(App.BaseUri, data);

The value you're seeing in Fiddler is the value you're sending.

var data = new HttpFormUrlEncodedContent(
new Dictionary
{
["value"] = content
}
);

You're telling the code to post a URL-encoded form, with a single key called "value", whose value is the URL-encoded JSON string representing your content. That results in a body containing:

value=%7B%22IDBusta%22%3A22%2C%22NomeCliente%22%3A%22fff%22%2C%22Prezzo%22%3A22.0%7D

If you decode the value, you get:

{"IDBusta":22,"NomeCliente":"fff","Prezzo":22.0}

This is the mehod Web api "POST":

// POST: api/Bustas
[ResponseType(typeof(Busta))]
public IHttpActionResult PostBusta(Busta busta)
{
if (!ModelState.IsValid)
{

            return BadRequest(ModelState);

            
        }
           
            db.Bustas.Add(busta);
            db.SaveChanges();
        

        return CreatedAtRoute("DefaultApi", new 
                     { id = busta.IDBusta }, busta);
    }

putting a breakpoint on this line

db.Bustas.Add(busta);

this result is (IDbusta = 3 , NomeCliente = nulll, prezzo = 0)
