Question

我有更新的ajax功能，它告诉我404找不到....

我的C＃代码：

   [HttpPut]
    public ActionResult DoUpDate(Country co)
    {
        string message = "";
        bool status = false;
        Database_AjaxEntities db = new Database_AjaxEntities();
        Country country = db.Countries.Find(co.CountryId);
        country.CountryName = co.CountryName;

        db.SaveChanges();

        status = true;
        message = "Successfully Saved!";
        return new JsonResult { Data = new { status = status, message = message }, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
    }

和我的Ajax代码：

    function Update(id) {

    var updatedCountry = {
        CountryId: id,
        CountryName: $('#txtCountryName').val()
    };
    $.ajax({
      url: '@Url.Action("DoUpDate", "Home")',
        type: 'PUT',
        contentType: "application/json",
        data: JSON.stringify(updatedCountry),
        success: function () {

        },
        error: function (xhr, ajaxOptions, thrownError) {
            console.log(xhr.responseText);
        }
    });
    return false;
}

这就是我在控制台中得到的结果：

http://localhost:57251/Home/DoUpDate

无法加载资源：服务器响应状态为404（未找到）
