FromBody value get null

Question

This is Asp.Net Webform application
This is my POST method in my Apicontroller

public void Post([FromBody]string value)
{
}

I'm with fiddler post process.
I did so experiment.
But it did not.

What is the problem.
Can you help?

I've tried it, I've failed.

public void Post(MyViewModel model)
{
   string aa = model.Value;
}

public class MyViewModel
{
   public string Value { get; set; }
}

In Fiddler:

Request Body:   
Value=hakan

Solution 1

The POST body payload in Fiddler should be:

=foo_bar

instead of:

value=foo_bar

That's just one of those strange things about the model binding in the Web API. If you want to support value=foo_bar in the POST body payload you could always write a view model:

public class MyViewModel
{
    public string Value { get; set; }
}

and then have your method take this view model as parameter:

public void Post(MyViewModel model)
{
    ... work with model.Value here as usual
}

Solution 2

I meet this issue, and the solution is:
to fit the Request Body format =foo_bar,
also need Request haders:

Content-Type: application/x-www-form-urlencoded

Edited my question. Can you check?

[Darin Dimitrov]

Did you set the Content-Type request header to application/x-www-form-urlencoded in Fiddler?

I was having the same problem with a Windows Java program (using Scala and Dispatch). This answer solved it for me also.

Thanks - adding "Content-Type: application/x-www-form-urlencoded" worked for me.
