如果需要添加防伪验证，请尝试从标头发送__RequestVerificationToken。

 $.ajax({
                url: '@Url.Action("SaveUser", "PersonalInfo")',
                type: 'POST',
                headers : {
                  RequestVerificationToken:
                      $('input:hidden[name="__RequestVerificationToken"]').val()
                },                   
                data: JSON.stringify(UserVmodl),
                contentType: 'application/json; charset=utf-8',
                dataType: 'json',
                async: true,
                success: function (data) { localSuccess(data); onSuccessFunc(data); }
            });

请记住在表单中添加@Html.AntiForgeryToken()。此外，你需要返回一个json结果，因为你的ajax需要一个返回类型的json。
