C＃MVC Ajax模式验证-500内部服务器错误

Question

我不是很确定为什么这行不通，我在项目的不同部分有完全相同的东西，我得到“ POST” 500（内部服务器错误），我只是试图得到@using（ Ajax.BeginForm（验证是否可以在模式上工作。就像我说的那样，我已经在项目的不同部分上工作了，并且可以正常工作。我的模式已成功填充，但是当我单击“提交”按钮时，我得到了上面的错误。查看模态和模态的控件我有

HtmlHelper.UnobtrusiveJavaScriptEnabled = true;

我的代码中有所有这些库。

    [HttpPost]
    [ValidateAntiForgeryToken]
    [HandleError]
    public ActionResult PartNumberUpdate(FindPartModel model){/*skip*/}

您在操作上方添加了[ValidateAntiForgeryToken]。

但是您的视图中没有@Html.AntiForgeryToken()。

@using (Ajax.BeginForm("PartNumberUpdate", "Parts", new AjaxOptions() { HttpMethod = "POST", UpdateTargetId = "PartNumControls", OnSuccess = "ajaxPartUpdate" })){
    @Html.AntiForgeryToken() //Add me
    //skip
}
