angular post request to a asp.net web API server - angularjs

Question

IN angular js i am trying to send a post request her is the controller.
.controller('ActivationController',['$http','$location','$routeParams','AuthService',
function($http, $location, $routeParams, AuthService){
var location = $location.path();
var activation_code = $routeParams.code;
var activationLink = "http://localhost:18678/api/User/ActivateUser";
console.log(activation_code);
if(activation_code){
$http({method:"post", url:activationLink, data:activation_code}).success(function(response){
console.log(response);
}).error(function(error){
console.log(error);
});
}
}]);
and in asp.net web API her is the method.
[HttpPost]
public HttpResponseMessage ActivateUser([FromBody]string activation_code)
{
if (!string.IsNullOrWhiteSpace(activation_code))
{
string decode_token = HttpUtility.UrlDecode(activation_code); ;
string token_string = Crypto.Decrypt(activation_code, passPhrase);
if (token_string != null)
{
User activateAcc = db.Users.Where(user => user.ConfirmToken == token_string).SingleOrDefault();
if (activateAcc != null)
{
activateAcc.IsActive = true;
try
{
db.SaveChanges();
var credential = new UserCredential();
credential.EmailAddress = activateAcc.UserMail;
credential.Password = activateAcc.UserPassword;
return Request.CreateResponse(HttpStatusCode.OK, credential);
}
catch
{
return Request.CreateResponse(HttpStatusCode.Ambiguous, "cannot confirm account");
}
}
else
{
return Request.CreateResponse(HttpStatusCode.NotAcceptable, "invalid account");
}
}
else
{
return Request.CreateResponse(HttpStatusCode.NoContent, "invalid token data");
}
}
else
{
return Request.CreateResponse(HttpStatusCode.NoContent, "missing activation code");
}
}
The problem is when the controller fire the request is made but without sending any data to the server. The [FromBody]string activation_codeis null

Wrap your parameter in quotes:
$http({method:"post", url:activationLink, data: '"' + activation_code + '"'});
Explanation
For Web API to bind to a simple string primitive, the body must be specified as:
"some string here"
For example:
POST http://localhost:5076/api/values HTTP/1.1
User-Agent: Fiddler
Host: localhost:5076
Content-Type: application/json
Content-Length: 7
"Alice"
The quotes are important. For more information, check this article.
