c# - string is null when posting from Angular to Web API? -

when try post string web api, value null. have tried wrapping in quotes, still null.

angularjs code:

return $http.post("http://localhost:59437/api/recaptcha/post",                                      vcrecaptchaservice.getresponse()); 

web api code:

[enablecors("*", "*", "*")] public class recaptchacontroller : apicontroller {     public string post([frombody] string response)     {         return response;     } } 

i not sure how works because, don't have response in form body. vcrecaptchaservice.getresponse() returns response string , going send google's verify api verify recaptcha, [frombody] part doesn't make sense me if not part of body

your post call should sending data in json format {response: 'something'}

  return $http.post("http://localhost:59437/api/recaptcha/post",         { response: vcrecaptchaservice.getresponse() } //data    );
