c# - 传入字典的模型项的类型为 'System.Net.Http.HttpResponseMessage' ，

Question

完全错误

The model item passed into the dictionary is of type 'System.Net.Http.HttpResponseMessage', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`

我正在尝试使用 viewmodel 从 web api 获取一些数据。

这是我的行为

public ActionResult PayBilgileri()
    {
        Session["dersGrupID"] = 470122;
        int DersGrupID = Convert.ToInt32(Session["dersGrupID"]);

        Core.ViewModel.Ders.DersDetay.PayVeNotBilgileriViewModel PayBilgileri = new Core.ViewModel.Ders.DersDetay.PayVeNotBilgileriViewModel();

        PayBilgileri.DersPlanID = DersGrupID;

        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://myapi.com");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            //HttpResponseMessage response = client.GetAsync("api/Ders/ListelePaylarVeNotBilgileri").Result;
            var response = client.PostAsJsonAsync("api/Ders/ListelePaylarVeNotBilgileri", PayBilgileri).Result;
            if (response.IsSuccessStatusCode)
            {

            }
            return PartialView(response);
            // PartialViewResult(response, JsonRequestBehavior.AllowGet);
        }

    }

和局部 View

@model IEnumerable<Core.ViewModel.Ders.DersDetay.PayVeNotBilgileriViewModel>

<table class="table">

@foreach (var item in Model) 
{
   <tr>
      <td>
          @Html.DisplayFor(modelItem => item.KatkiOrani)
      </td>
   </tr>
}
</table>

Answer 1

您需要从 HttpResponseMessage 中提取数据作为IEnumerable<PayVeNotBilgileriViewModel>然后才将其作为 View 模型传递:

if (response.IsSuccessStatusCode)
{
    var vm = response.Content.ReadAsAsync<IEnumerable<PayVeNotBilgileriViewModel>>().Result;
    return PartialView(vm);
}

参见 ReadAsAsync
