Question

我想在同一个控制器的Action结果中发布控制器名称 Home 的Mvc Action结果，Post请求发送成功，但参数丢失了传递值。

从控制器主页调用帖子

   [ValidateInput(false)]
    [HttpPost]
    public ActionResult addToWishList(string customcode, string addcusimgSVG, string pagestatus = "", string userinformation="")
    {

        string URI = "http://localhost:49389/services";
        string myParameters = "serviceAndVisitorModel=" + ServiceAndVisitroData;

        using (WebClient wc = new WebClient())
        {
            wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
            string HtmlResult = wc.UploadString(URI, myParameters);
        }
     //return some view here

    }

由同一控制器中的addToWishList调用的操作结果

  [Route("services")]
    [HttpPost]
    public ActionResult services(AllserviceWebApi serviceAndVisitorModel, string pagename = "service")//string selectedService,string userId,string DealInfo
    {

     //serviceAndVisitorModel is null here

    }

模型

public class AllserviceWebApi
{
    public string packageTypeID { get; set; }
    public string packageTypeCode { get; set; }
    public string pageUrl { get; set; }
    public string pageName { get; set; }
    public string displayName { get; set; }
    public string name { get; set; }
    public List<pakageInfoList> packageInfoList { get; set; }
    //------visitor object
    public string IPAddress { get; set; }
    public string deviceName { get; set; }
    public string OSName { get; set; }
    public string browserName { get; set; }
    public string countryName { get; set; }

    public string selectedService{ get; set; }
    public string userId{ get; set; }
    public string OrderId { get; set; }
    public string DealInfo { get; set; }
    public long wishlishid { get; set; }
    public string customlogoCode { get; set; }
    public string customLogoImgSvg { get; set; }
    public bool IsCustomllogo { get; set; }
}

模型初始化

 AllserviceWebApi ServiceAndVisitroData = new AllserviceWebApi()
            {
                selectedService = serviceids,
                userId = "0",
                OrderId = "0",
                DealInfo = "",
                IPAddress = ipaddress,
                // deviceName: userDevicedata[0],
                OSName = osandversion,
                browserName = browsermajorversion,
                wishlishid = wishid,
                customlogoCode = logocode,
                customLogoImgSvg = logosvg,
                IsCustomllogo = true

            };

请告诉我这段代码有什么问题。

尝试通过JSON发送

using Newtonsoft.Json;


    using (WebClient wc = new WebClient())
            {
                wc.Headers[HttpRequestHeader.ContentType] = "application/json";
                string HtmlResult = wc.UploadString(URI, JsonConvert.SerializeObject(ServiceAndVisitroData));
            }

PS你需要通过nuget安装Newtonsoft.Json

在相同控制器Asp.net Mvc
