What is difference is posting data via html form post and Ajax post?

Question

I have Post API like below. I am calling this via AJAX and I get request in user parameter but StreamReader comes as empty.

[HttpPost]
    [Route("getUserBankList")]
    public IHttpActionResult getUserBankList(UserProfile user)
    {
StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
      string getUserBankList = reader.ReadToEnd();
    }

I have another Post API like below. I am calling this via HTML form post but I get req parameter as empty but StreamReader is able to fetch posted data.

[HttpPost]
    [Route("getUserBankList")]
    public IHttpActionResult ValidateToken(ValidateRequest req)
    {
StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
      string getUserBankList = reader.ReadToEnd();
    }

Could anybody please explain how in above two differnt post data is getting send.

Answer 1

You didn't return any thing form action after successfully execute your's action.

return Ok(getUserBankList);

Please add above line after getting the response in reader.ReadToEnd()
