I developed a service with C # that consulted a database with certain functions.
I went from AngularJS to Angular2 and here my problems came.
Inside my WCF I have:
[OperationContract]
[WebInvoke(UriTemplate = "/GetCaptaciones", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat=WebMessageFormat.Json , BodyStyle = WebMessageBodyStyle.Wrapped)]
List<Captacion> GetCaptaciones(int id_captador)
From Angular2 I'm making the call to this method like this:
let data = JSON.stringify({ id_captador: 11 });
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
this.http.post(url + "/GetCaptaciones", data, options).subscribe(data => {
console.log(data);
});
But I get the error that the input data is not correct. Receive data Raw while the data you expect is JSON . However, if I copy Postman JSON and send everything works correctly.
