无法获取从 AJAX 传递到我的 API 控制器的 searchValue、orderColumn、orderDirection

问：

因此，为了获取数千个数据集并使用 ajax 获取数据，我正在尝试在我的 API 中集成数据表服务器端。

这是我的 API 代码

[HttpGet("GetServerData")]
        public ActionResult GetServerData(int draw, int start, int length, string searchValue, string orderColumn, string orderDirection)
        {
            var query = _context.Products.AsQueryable();

            //Apply filtering based on searchValue
            if (!string.IsNullOrEmpty(searchValue))
            {
                query = query.Where(p => p.Name.Contains(searchValue));
            }

            // Apply sorting
            if (!string.IsNullOrEmpty(orderColumn) && !string.IsNullOrEmpty(orderDirection))
            {
                // Assuming orderColumn is a valid property name
                var propertyInfo = typeof(Product).GetProperty(orderColumn);
                if (propertyInfo != null)
                {
                    query = orderDirection == "asc"
                        ? query.OrderBy(p => propertyInfo.GetValue(p, null))
                        : query.OrderByDescending(p => propertyInfo.GetValue(p, null));
                }
            }

            // Count the total number of records before paging
            int totalRecords = query.Count();

            // Apply paging
            query = query.Skip(start).Take(length);

            var records = query.ToList();

            var response = new
            {
                draw,
                recordsTotal = totalRecords,
                recordsFiltered = totalRecords, // You might modify this based on your filtering logic
                data = records
            };

            return Ok(response);
        }

这是我的 AJAX 请求，

"ajax": {
            url: "https://localhost:7174/API/products/GetServerData",
            type: "GET",
            dataType: "json",
            data: function (d) {
                d.draw = d.draw || 1;
                d.start = d.start || 0;
                d.length = d.length || 10; // Records per page
                d.search = d.search || {};
                d.search.value = d.search.value || '';
                var order = d.order[0] || {};
                d.orderColumn = order.column || '';
                d.orderDirection = order.dir || '';
                d.searchValue = d.search.value || ''; // Ensure that searchValue is included
            },
            dataSrc: "data"
        },

这就是错误出现的原因

{“type”：“https://tools.ietf.org/html/rfc7231#section-6.5.1”，“title”：“一个 或更多验证错误 occurred.“，”status“：400，”traceId“：”00-245b7bb81d09c2a78a230e2a25c28a19-90e9f86d60626f3b-00“，”errors“：{”orderColumn“：[”这 orderColumn 字段为必填字段“]，”searchValue“：[”searchValue 字段 是必需的.“]，”orderDirection“：[”orderDirection 字段是 必需。“]}}

我的 AJAX 代码无法读取 searchValue、orderColumn 或 orderDirection 值，因此无法将它们传递给 API。

有什么建议吗？
