Question

我有ajax请求将数据发送到我的控制器，它会收集我的下拉列表的值

错误是

POST http://localhost:65070/form/create 500 (Internal Server Error)

错误的反应是

The required anti-forgery form field "__RequestVerificationToken" is not present.

更新我的表格

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>Form</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.FormName)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.FormName)
            @Html.ValidationMessageFor(model => model.FormName)
        </div>


        <div class="editor-label">
            @Html.LabelFor(model => model.MasterID, "MasterModule")
        </div>
        <div class="editor-field">
            @Html.DropDownList("MasterID", String.Empty)
            @Html.ValidationMessageFor(model => model.MasterID)
        </div>
        <select id="State" name="state"></select><br />
        <p>
            <input type="submit" value="Create" />
        </p>

    </fieldset>
}

我的ajax请求

$('#State').change(function () {
  var a = $('#State').val();
    $.ajax({
                url: "/form/create",
                type: "POST",
                data: { 'SubID': a },
                success: function (result) {
                    //        console.log(result);
                }
            });
        });

我的控制器

public ActionResult Create(Form form, int SubID)
        {
            if (ModelState.IsValid)
            {
                form.SubId =SubID;
                form.CreatedDate = DateTime.Now;
                form.CreatedBy = 1;
                form.CreatedDate = DateTime.Now;
                form.IsActive = true;
                form.ModifyBy = 1;
                form.ModifyDate = DateTime.Now;

                db.Forms.Add(form);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            ViewBag.MasterID = new SelectList(db.Departments, "MasterId", "ModuleName", form.MasterID);
            return View(form);
        }

它给出了500个内部错误..它的尴尬plz帮助

Answer 1

您的帖子方法必须具有[ValidateAntiForgeryToken]属性。删除属性或在视图中添加令牌

@Html.AntiForgeryToken()

并将其传回ajax函数

$('#State').change(function () {
  var a = $('#State').val();
  var token = $('[name=__RequestVerificationToken]').val();
  $.ajax({
    ....
    data: { __RequestVerificationToken: token, 'SubID': a },
    ....

请注意，操作方法

中不需要form参数

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(int SubID)
{
  ....

我有一个在我的应用程序中使用过的示例。在控制器中，您必须放置

 @Autowired
  AppService appService;  

@Autowired
AppDao ds;    
@Qualifier("nameParamJdbcTemplate")
@Autowired
public NamedParameterJdbcTemplate nameParamJdbcTemplate; 

I am new to spring so any help or working examples would be great. Thanks

在视图中，我有一个ajax函数

[HttpPost]
[ValidateAntiForgeryToken]
    public JsonResult Verificar(int idempleado, string desde, string hasta)
     {
      ...
     return Json(suiche, JsonRequestBehavior.AllowGet);
     }

在表单中，我使用function Verificar(desde, hasta) { var token = $('[name=__RequestVerificationToken]').val(); var empleadoId = parseInt($('#empleadoId').val()); var url = '/Settlements/Verificar'; var settings = { "async": true, "crossDomain": true, "url": url, "method": "POST", "data": { __RequestVerificationToken: token, idempleado: empleadoId, desde: desde, hasta: hasta, } } $.ajax(settings).done(function (response) { if (response) { $('#mensajefrom').text(null); $('#mensajeto').text(null); } else { $('#mensajefrom').text("There is another settlement with that date range"); $('#mensajeto').text("There is another settlement with that date range"); } }); }

POST 500（内部服务器错误）ajax，mvc
