Send a JavaScript object to an MVC controller using an HTTP POST request

I'm encountering an issue while attempting to send a JavaScript object containing a string and a jstring to an MVC controller. Despite my code looking correct, I am receiving a null value in the controller. Any assistance would be greatly appreciated.

 function setMultiQuestion(question, responses) {
 qaObject = new questionAnswerObj('q', [{'correct':true,'answer':'A1'},   {'correct':true,'answer':'A2'}];);

 $http.post(baseUrl + "Admin/insertMultiAnswers", { qaObject: qaObject })
  .success(function (data, status, headers, config) {
  })
  .error(function (data, status, header, config) {
  });
}

public ActionResult insertMultiAnswers(string[] qaObject)
{
    Console.Write(qaObject);
}

Answer №1

Ensure to transmit a string to the server by following these instructions:

$http.post(baseUrl + "Admin/addMultipleResponses", { data: JSON.stringify(dataset) })

To convert a Javascript object into JSON text and save it as a string, utilize the JSON.stringify function.

One way to modify your parameter is by making it dynamic

  public ActionResult insertMultiAnswers(string[] qaObject)

can be updated to

  public ActionResult insertMultiAnswers(dynamic qaObject)
