Web API Return 400 BAd Request

[arjunender pabba]

Hi

c# Web API Returning 400: BAD REQUEST - The request could not be processed by the server due to invalid syntax

from angular httpclient post method but

the same is working with get method

in Postman every thing is working fine

Here is the angular code

var headers = new HttpHeaders();

    headers.append('Content-Type', 'application/json');

var options = {

      headers: headers

   }

this.http.post(this.url,

   {

    "User_Id":  "1",

    "User_Name":  "arjun",    

},options)

.subscribe(

data  => {

console.log("POST Request is successful ", data);

Web API Code :

public HttpResponseMessage Post([FromBody]User user) {

  var message = Request.CreateResponse(HttpStatusCode.Created, user);

                    return message;

}

Any suggessions

Thanks

Arjun
