Can't get the MvcActionValueBinder to work with json body? about webapicontrib HOT 9 CLOSED

Why are you trying to deserialize UpdateAccountCreditLimitRequest (single item) into FormDataCollection (array)? Why do you need MvcActionBinding here?

from webapicontrib.

Here is my SO post which should explain better.

I need MvcActionBinding here because I'm trying to populate a single incoming request object with a parameter FromUri and the rest FromBody. Web Api 2 doesn't allow you to do this out of the box and after searching, I thought this was the way to go.

To formally match request model with model, try using ICollection<UpdateAccountCreditLimitRequest>.

But here's what works for me out of the box:

[Route("api/payment")]
public async Task<IHttpActionResult> PostStartPayment(StartPaymentRequest request, bool sync = true)
{
}

which is inboked by url:

POST http://example.com/api/payment/?sync=false

{
    "foo" : "bar" // request body goes here
}

In other words: try swap arguments order.

P.S.
You don't need [FromBody] since PUT is from body by default (by the HTTP spec).

P.P.S.
You don't need [HttpPut] if you name your method PutUpdateAccountCreditLimit().

from webapicontrib.

Changing the order of parameters doesn't help. Please see the stack overflow post. Following your example above, if there was a property called sync on your StartPaymentRequest object, it will NEVER be populated FromUrl. How can I get some of the request object's properties to populate via a combination of the body/url? Again I'm using Web Api (not MVC where this works out of the box).

This assumes the body is FormUrl encoded, however, my body is json.

I don't think object's properties can be populated from both, only from either.

My example shows that different parameters can be populated differently (one form body, another from url).

from webapicontrib.

There are tests in this project showing that an object can be populated from both body and uri. Here is the controller in MvcActionValueBinderTests.cs

[MvcStyleBinding]
public class MvcController : ApiController
{
    [HttpGet]
    public Customer Combined(Customer item)
    {
        return item;
    }
}

Here is the test.

[Test]
public void TestOneFieldFromUriOneFromBody()
{
    var request = new HttpRequestMessage
    {
        Method = HttpMethod.Get,
        RequestUri = new Uri("http://localhost:8080/Mvc/Combined?age=10"),
        Content = FormUrlContent("name=Fred")
    };

    var response = client.SendAsync(request).Result;
    var actual = response.Content.ReadAsAsync<Customer>().Result;

    var expected = new Customer { name = "Fred", age = 10 };
    Assert.That(actual, Is.EqualTo(expected));
}

This works. However, there is one difference from this test and what I'm trying to do. I'd like to populate the object from ROUTE data and BODY data (not QUERYSTRING and BODY).

I don't quite get what do you mean "from route". Does it work for you If do this in query string?
