Question

我希望在没有FromBody标签的情况下将复杂对象发送到我的.NET Core API。

我希望用JQuery做的很简单，但我无法弄清楚如何从C＃Web API客户端复制逻辑。

为了测试，我有一个相当简单的对象。

[Serializable]
public class FilterModel
{
    public int? PageSize { get; set; }
    public int Page { get; set; }
}

为了测试，我们还有一个非常简单的控制器方法

[HttpPost("TEST")]
public virtual int GetTEST(Common.FilterModel filter, Common.FilterModel filter2)
{
    return ((filter.Page * filter.PageSize ?? 0) + (filter2.Page * filter2.PageSize ?? 0));
}

显然代码的用例会让我更复杂，但我只是想在这个时候获取值。

调用此方法的JQuery非常简单，并且完美无缺：

var myData = {"filter":{"pageSize":3,"page":2},
            "filter2":{"pageSize":19,"page":1}};
$.ajax({
  type: 'POST',
  url: '/api/Authentication/TEST',
  data: myData
}).done(function (data, statusText, xhdr) {
  JsonResponse = data;
  console.log(data);
}).fail(function (xhdr, statusText, errorText) {
  //console.log(JSON.stringify(xhdr));
});

但是尝试从HttpClient复制该逻辑会导致0;在API端接收时，模型始终为空。我已经尝试了一些不同的方法，从JSON序列化ArrayList / Dictionary到我在下面添加的内容，但我不知道我哪里出错了。

        HttpClient client = new HttpClient
        {
            BaseAddress = new Uri("http://localhost:65447/")
        };
        ApiCommon.FilterModel filter = new ApiCommon.FilterModel()
        {
            PageSize = 10,
            Page = 1
        };
        ApiCommon.FilterModel filter2 = new ApiCommon.FilterModel()
        {
            PageSize = 9,
            Page = 41
        };


        MultipartFormDataContent mpContent = new MultipartFormDataContent();
        StringContent content = new StringContent(JsonConvert.SerializeObject(filter));
        content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
        mpContent.Add(content, "filter");
        content = new StringContent(JsonConvert.SerializeObject(filter2));
        content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
        mpContent.Add(content, "filter2");
        var retval = 
              JsonConvert.DeserializeObject<int>(
                  client.PostAsync("/api/Authentication/TEST", mpContent)
                  .Result.Content.ReadAsStringAsync().Result);
        Console.WriteLine(retval);

有没有办法模仿JQuery调用来通过HttpClient工作？我错过了一些关键的东西吗？

编辑：在让小提琴手拿起它之后，这是每个的原始数据，我将尝试将其与我的更改相匹配。
