我正在使用ASP.NET Core Razor Pages。我得到一个错误时，尝试 AJAX 请求访问OnPostshiftDataUp

ERROR : Failed to load resource: the server responded with a status of 400 () 

console.log(formdata) // serialize data

serverip=172.16.224.999&printername=Zebra2&Location=SupervisorOffice&__RequestVerificationToken=CfDJ8DvYZnvxyLVKi-zvp3jzTImPtgQsnvTBz4ot8mbln2lEaqGcaT_gzZ-KNNfuEBoqHYSBIdcahXL3LLuum4nfTi2oZDQj-PfodyDAVpa45rYEIb7EcRvHrMn71AyB8PMC6DrqvT8q3cCEcSlt1sYQJ-M

但是断点不捕捉这个函数的意思是没有检测到有断点一定要捕捉它
AJAX 请求主要目的是在bootstrap模型上更新数据后保存数据
我为我的代码尝试什么
1-在页面模型上发布类型的函数

public ActionResult OnPostshiftDataUp()
        {

            
            return Content("msg");
           
        }

2- AJAX request to access function or action OnPostshiftDataUp ajax request i do it

$('#save-btn').click(function () {
                var formData = $('#edit-form').serialize();
                console.log(formData);
            
                $.ajax({
                    url: '?handler=shiftDataUp',
                    
         
                    type: "POST",
                  
                    data: JSON.stringify(formData),
            
                   
                    success: function (result) {
                     
                        $('#edit-modal').modal('hide');
       
                        location.reload();
                    },
                    error: function (xhr, status, error) {
                        console.log(error);
                    }
                });
            });

bootstrap模型然后发送 AJAX 请求时，点击按钮保存

您收到一个400 Bad Request，因为您没有通过Razor Pages默认内置的反请求伪造检查：https://www.learnrazorpages.com/security/request-verification
当您将表单数据转换为JSON时，请求验证令牌作为JSON有效负载的一部分隐藏在请求主体中。Razor Pages无法在这种情况下读取令牌，因此您需要在头中发送请求验证令牌：

$.ajax({
    url: '?handler=shiftDataUp',
    type: "POST",
    contentType: "application/json",
    headers: {
        "RequestVerificationToken" : $('[name="__RequestVerificationToken"]').val()
    },
    data: JSON.stringify(formData)
    ...

或者，不要将表单序列化为JSON。按原样发送：

$.ajax({
        url: '?handler=shiftDataUp',
        type: "POST",
        data: $('#edit-form').serialize()
        ...
