非常感谢你的帮助。我从工作中得到了一项任务，自从我被困之后已经有两周了。非常感谢您的帮助和建议。我正在使用ASP.NET核心2.1和EnitityFramework。我收到此错误“：HTTP404：未找到 - 服务器未找到任何与请求的URI匹配的内容（统一资源标识符）。（XHR）POST - https://localhost:44336/EducationPage?handler=Add”我现在已经尝试了两周。谢谢您的帮助。我有一个名为EducationPage的RazorPage。在该页面内，我填充了我的数据。在同一页面中，我希望允许用户通过单击“创建”按钮创建新的“教育”对象，该按钮将弹出一个表单。用户输入数据，一旦点击添加按钮，我的ajax代码将被触发。这是我的表格

我的Ajax代码是这样的：
<script>
$("#btnAdd").click(function () {
var options = {};
options.url = "/EducationPage?handler=Add";
options.type = "POST";
var obj = {};
obj.eduId = $("#eduId");
obj.userId = $("#userId");
obj.instName = $("#instName").val();
obj.certName = $("#certName").val();
obj.major = $("#major").val();
obj.startDate = $("#startDate").val();
obj.endtDate = $("#endDate").val();
obj.descrp = $("#descp").val();
console.log(obj);
options.data = JSON.stringify(obj);
options.data = $("#myForm").serialize;
//console.log(options.data)
options.contentType = "application/json; charset=utf-8";
options.dataType = "json";
options.beforeSend = function (xhr) {
xhr.setRequestHeader("MY-XSRF-TOKEN",
$('input:hidden[name="__RequestVerificationToken"]').val());
};
options.success = function (msg) {
$("#msg").html(msg);
};
options.error = function () {
$("#msg").html("Error while making Ajax call!");
};
console.log(options);
$.ajax(options);
});
</script>
我的后端是代码就是这个
[HttpPost]
public async Task<IActionResult> OnPostAdd([FromBody] Obj obj)
{
if (!ModelState.IsValid)
{
return Page();
}
var UserInDB = await _userManager.GetUserAsync(HttpContext.User);
obj.UId = UserInDB.Id;
_db.Obj.Add(obj);
await _db.SaveChangesAsync();
return new JsonResult("Customer Added Successfully!");
}
The error message I am getting is this :
HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).
"(XHR)POST - https://localhost:44336/EducationPage?handler=Add"
它现在正在工作，我的坏，我不小心在我的服务中有一个空间.AddAntiforgery（option => option.HeaderName =“MY-XSRF-TOKEN”）;我删除了它，它的工作原理。所以上面的代码没什么不好
