我在尝试将一些数据从 DataTable 中的几个选定行发送到 MVC 操作时做了什么:
HTML 在页面的开头:
@Html.AntiForgeryToken()
(只显示一行,从模型绑定):
 @foreach (var item in Model.ListOrderLines)
                {
                    <tr data-orderid="@item.OrderId" data-orderlineid="@item.OrderLineId" data-iscustom="@item.IsCustom">
                        <td>@item.OrderId</td>
                        <td>@item.OrderDate</td>
                        <td>@item.RequestedDeliveryDate</td>
                        <td>@item.ProductName</td>
                        <td>@item.Ident</td>
                        <td>@item.CompanyName</td>
                        <td>@item.DepartmentName</td>
                        <td>@item.ProdAlias</td>
                        <td>@item.ProducerName</td>
                        <td>@item.ProductionInfo</td>
                    </tr>
                }
启动 JavaScript 函数的按钮:
 <button class="btn waves-effect waves-light btn-success" onclick="ProcessMultipleRows();">Start</button>
JavaScript 函数:
  function ProcessMultipleRows() {
            if ($(".dataTables_scrollBody>tr.selected").length > 0) {
                var list = [];
                $(".dataTables_scrollBody>tr.selected").each(function (e) {
                    var element = $(this);
                    var orderid = element.data("orderid");
                    var iscustom = element.data("iscustom");
                    var orderlineid = element.data("orderlineid");
                    var folderPath = "";
                    var fileName = "";
                    list.push({ orderId: orderid, isCustomOrderLine: iscustom, orderLineId: orderlineid, folderPath: folderPath, fileName : fileName});
                });
                $.ajax({
                    url: '@Url.Action("StartWorkflow","OrderLines")',
                    type: "post", //<------------- this is important
                    data: { model: list }, //<------------- this is important
                    beforeSend: function (xhr) {//<--- This is important
                      xhr.setRequestHeader("RequestVerificationToken",
                      $('input:hidden[name="__RequestVerificationToken"]').val());
                      showPreloader();
                    },
                    success: function (data) {
                    },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {
                    },
                     complete: function () {
                         hidePreloader();
                    }
                });
            }
        }
MVC 动作:
[HttpPost]
[ValidateAntiForgeryToken] //<--- This is important
public async Task<IActionResult> StartWorkflow(IEnumerable<WorkflowModel> model)
和 C# 中的模型:
public class WorkflowModel
 {
        public int OrderId { get; set; }
        public int OrderLineId { get; set; }
        public bool IsCustomOrderLine { get; set; }
        public string FolderPath { get; set; }
        public string FileName { get; set; }
 }
结论:
错误的原因:
"Failed to load resource: the server responded with a status of 400 (Bad Request)"
是属性:[ValidateAntiForgeryToken]对于MVC动作StartWorkflow
Ajax 调用中的解决方案:
  beforeSend: function (xhr) {//<--- This is important
                      xhr.setRequestHeader("RequestVerificationToken",
                      $('input:hidden[name="__RequestVerificationToken"]').val());
                    },
要发送对象列表,您需要形成示例中的数据(填充列表对象),并且:
数据:{模型:列表},
类型:“帖子”,
