ajax 调用 actionmethod 的参数中没有嵌套对象值

Question

参数中的嵌套对象值不符合。我怎样才能得到完整的对象，包括嵌套值在控制器的 actionmethod 中遵循？

当我调用ajac方法时，图片上红色圆圈内的对象中有值。但是在controller里面没有跟随

mapHub.client.requestForHelpInClient = function (requestDetails) {
                debugger;
                $.ajax({
                    type: "GET",
                    url: '@Url.Action("RequestPartialView", "Supplier")',
                    data: requestDetails,
                    success: function (response) {
                        $("#Request").html(response);
                    },
                    error: function (error) {
                        console.log(error);
                    }
                });                }

  function requestForHelp() {
            requestDetails = {
                CustomerId: @Model.Customer.CustomerID,
                NumberOfHours: $("#numberOfHoursTextBox").val(),
                TypeOfMachine: $("#typeOfMachineDropDownMenu").children("option:selected").val(),
                CustomerLocation: CustomerPosition,
                NearestSupplierList: nearestSuppliers
                //StartDate: $( "#startDate" ).val(),
                //EndDate: $( "#endDate" ).val(),
            }
            mapHub.server.requestForHelp(requestDetails);


public class RequestDetails
{
    public int CustomerId { get; set; }
    public Customer Customer { get; set; }
    public MapClient CustomerLocation { get; set; }
    public int NumberOfHours { get; set; }
    public string TypeOfMachine { get; set; }
    public List<MapClient> NearestSupplierList { get; set; }    
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
}

 public void RequestForHelp(RequestDetails requestDetails)
    {

        requestDetails.Customer =   Service.CustomerService.GetCustomerById(requestDetails.CustomerId);
Service.SupplierService.GetAspNetUserIDBySupplierID(requestDetails.NearestSupplierList[0].ClientId);

            Clients.User(supplierAspNetUserID).requestForHelpInClient(requestDetails);
    }

为您提供两个快速更改。

您正在使用 GET 方法。 GET 方法不能那样传输数据。将控制器和 ajax 中的 GET 更改为 POST。
您需要在控制器中添加一个[FromBody]标签。根据您使用的 MVC 版本，数据绑定器可能对此特别挑剔。

控制器：

[HttpPost]
public ActionResult RequestPartialView([FromBody]RequestDetails reqDetails)
{
   // code here 
}

Ajax:

mapHub.client.requestForHelpInClient = function (requestDetails) {
    $.ajax({
        type: "POST",
        url: '@Url.Action("RequestPartialView", "Supplier")',
        data: requestDetails,
        success: function (response) {
            $("#Request").html(response);
        },
        error: function (error) {
            console.log(error);
        }
    });  
}
