I'm trying to execute an ajax POST, but always return an 500 Server Error.

For perfom a test, I simplify the request.

Javascript code:

 $(document).ready(function() {
  // Add the page method call as an onclick handler for the div.
      $("#prova").click(function() {
        $.ajax({
          type: "POST",
          url: "Solicitud.aspx/GetDate",
          data: {someParameter: "some value"},
          contentType: "application/json; charset=utf-8",
          dataType: "json",
          success: function(msg) {
            // Replace the div's content with the page method's return.
            console.log("Resposta"+ msg.d);
          }
        });
      });
        });

Class Code

namespace picovirgiliop
{
    public partial class Solicitud : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        [WebMethod]
        public static string GetDate(string someParameter)
        {
            return DateTime.Now.ToString();
        }
...

EDIT

POST http://localhost:63010/Solicitud.aspx/GetDate 500 (Internal Server Error)

• send @ jquery-3.3.1.js:9600
• ajax @ jquery-3.3.1.js:9206
• (anonymous) @ Solicitud:300
• dispatch @ jquery-3.3.1.js:5183
• elemData.handle @ jquery-3.3.1.js:4991

Answer 1

As per your code review, I can see problem at line

data: {someParameter: "some value"},

It should be something like below,

data: "{ 'someParameter': 'some value' }",

OR

data: "{ someParameter: 'some value' }",
