How to pass string in post request body in postman

Question

I have an POST API end point, i.e.

[Route("api/{parameter1}/employee")]
[HttpPost]
public Employee RegisterEmployee(string parameter1, [FromBody] string parameter2)

Now, I want to hit this API from postman.

My request URL is:

http://localhost:xxxxx/api/parameter1/employee

And the body is:

So, in this way i am getting: 415 Unsupported Media Type error.

If i try other ways then i am able to hit the API, but parameter2 is always coming as null.

So, how should i pass the parameter2 value in postman?

Solution

Try setting content type to application/json. JSON String inputs thankfully capture as strings in ASP.NET Core.

Alternatively, you could read the body string from the request stream:

using (StreamReader reader = new StreamReader(Request.Body, Encoding.UTF8))
{  
    return await reader.ReadToEndAsync();
}
