ASP.NET 4.0과 상호 작용할 때 jQuery Ajax가 응답하지 않는 이유는 무엇입니까?

$.ajax({
  url: "your-url",
  type: "POST",
  data: "your-data",
  success: function(data) {
    // 执行成功回调的代码
  },
  error: function() {
    // 执行失败回调的代码
  }
});

protected void Application_BeginRequest(object sender, EventArgs e)
{
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");

    if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
    {
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods",
        "GET, POST, PUT, DELETE");
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers",
        "Content-Type, Accept");
        HttpContext.Current.Response.End();
    }
}

$.ajax({
    //Ajax参数
}).done(function(data) {
    //成功回调
}).fail(function(xhr, status, error) {
    //失败回调
    console.log(xhr.responseText);
});
