ASP.NET MVC AJAX POST ValidateAntiForgeryToken

我的代码中出现了一个内部服务器错误：

@using (Html.BeginForm("", "Manage", FormMethod.Post, new { role = "form"}))
{
    @Html.AntiForgeryToken()
}
<script>
function Like(id) {
    var requestData = {
        profileId: id,
        __RequestVerificationToken: $('[name=__RequestVerificationToken]').val(),
    };

    $.ajax({
        url: '/Manage/Like',
        type: 'POST',
        data: JSON.stringify(requestData),
        dataType: "json",
        contentType: 'application/json; charset=utf-8',
        error: function (xhr) { alert('Error: ' + xhr.statusText); },
        success: function (result) {},
        async: true,
        processData: false
    });
}
</script>

如果我删除[ValidateAntiForgeryToken]，一切正常，但我会失去安全性。如何修复内部服务器错误

我在fiddler SyntaxView 2请求中看到： /管理/喜欢 {profileId:13，请求验证项：jH2ofYlcTiHl8lixW(Anehog5KWRH5XL43LQFGKDFH55JX-X5CMZ4RFPTBDFU92OQSTM7ZSOP83LDFBXMDIIELYZKFBYFCXJUP-5MWYKZCQZJ2GY6QW0IQOTLSQADJFSZONYQM2MD42CBITZW2}

/管理

删除JSON.stringify

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Like(string profileId)
{ ... }

function Like(id) {
 var form = $('form');
 var token = $('input[name="__RequestVerificationToken"]', form).val();
 $.ajax({
    url: '/Manage/Like',
    type: 'POST',
    data: { __RequestVerificationToken: token, profileID: id },
    error: function (xhr) { alert('Error: ' + xhr.statusText); },
    success: function (result) {},
    async: true,
    processData: false
 }); 
}
