Asp.net mvc 仅Internet Explorer中的例外情况：“；“所需防伪表单字段”__RequestVerificationToken“；“不存在”；

我知道有很多类似的问题，但这是不同的： 此异常仅在IE中发生

这也是在登录页面。表单上有

@Html.AntiForgeryToken（）

，使用或不使用此选项：

var addAntiForgeryToken = function (data, form) {
    data.__RequestVerificationToken = $("#" + form + " input[type=hidden]   [name='__RequestVerificationToken']").val();
return data;
};
var formdata = addAntiForgeryToken($(this), 'login-form').serialize(), 

\uu RequestVerificationToken

字段始终存在于formdata中（在IE的调试模式下）；但ajax登录函数总是返回此异常。为什么?

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

序列化数据如下所示：（但它表示它不存在）

你的剧本毫无意义。如果使用

var formdata=$（'login-form'）.serialize（）

然后该令牌将被序列化并包含在数据中（假设您在表单标记中包含了

@Html.AntiForgeryToken（）

）。无需再次尝试添加。注意，我说过“无论是否使用

代码块

，\uu RequestVerificationToken字段始终存在于formdata中”，我的意思是这不是问题！在没有脚本的情况下使用

.serialize（）

，效果很好！我发现我的问题是如何在IE中使用ajax函数。因为服务器端也不存在所有其他字段（当我禁用AntiForgeryToken属性时）。因此，我将添加我的ajax函数，看看它是否存在任何问题，即它在IE中不工作。我已经测试了

.serialize（）

，但没有成功！

 $(function () {
        configValidations();
        $('#login-form').submit(function (e) {
            e.preventDefault();
            $("#result").html("");
            if ($(this).valid()) {
                var formdata = $('#login-form').serialize();
                wait();
                $.ajax({
                    url: this.action,
                    type: this.method,
                    cache: false,
                    data: formdata,

                    }
                }).done(function (response) {
                    unwait();
                    if (response.Content == null) {
                        $("#result").html(ajaxErrorMessage(response.Errors[0]));
                    }
                    else {
                        window.location = response.Content
                    }
                }).fail(function (error) {
                    $('#result').html(ajaxValidationBootstrap(error));
