Format response data for text/plain

[Jakub27blue]

Hello everyone,
I want to set the [Produces ("text/plain")] attribute for a method that returns an int value.
Unfortunately, the method returns a status code of 406.
Code:

        [Produces("text/plain")]
        public int Get()
        {
            return 1;
        }

Request:
without accept header
Response:
Error: response status is 406

In the documentation:

By default, ASP.NET Core supports the following media types:
application/json
text/json
text/plain

The documentation is not clear about this.
Do you know how to return an int value in text/plain format?

Hi my friend,

try this method.

[HttpGet("GetById")]
public IActionResult GetById()
{
    int returnedValue = 1;

    return Ok(returnedValue);
}

I am currently using this solution.
I wonder why there are no built-in formatters programs for built-in types like int or double.

[alierguc]

Because what you want to do is to send an http request to a method in the Controller class and return the specified constant value. This is what it should do for the api part.

I mean the formatting of the response type...
The only solution is to write your own formatting program for built-in types besides String.

[Produces(MediaTypeNames.Application.Json)]    ///Response: 1
[Produces(MediaTypeNames.Application.Xml)]    ///Response: <int>1</int>
[Produces(MediaTypeNames.Text.Plain)]    //Response: Error: response status is 406
public int Get()
{
     return 1;
}

The documentation needs to be corrected.
In my opinion, it is better to return specific type than IActionResult when the values are constant.

Yes, definitely. This method like better explanation to your requests.
