如何将 class 作为参数传递给 Web Api

Question

我想将 class 作为参数传递到我的网站 API。这是我的代码：

网络API:

[Route("api/[controller]")]
public class ValuesController : Controller
{

    [HttpPost]
    public string Post(ClusteringObject _cluesteringObject)
    {

        return _cluesteringObject.NumberOfCluster.ToString();
    }


}
public class ClusteringObject
{
    public string Data { get; set; }

    public int NumberOfCluster { get; set; }

}

我的测试控制台应用程序代码：

  class Program
{
    static void Main(string[] args)
    {
        HttpClient client = new HttpClient();
        client.BaseAddress = new Uri("http://localhost:57961/");
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json"));

        var testData = new ClusteringObject()
        {
            Data = "asdf",
            NumberOfCluster = 1
        };

        HttpResponseMessage response = client.PostAsJsonAsync("api/values", testData).Result;

        string res = "";
        using (HttpContent content = response.Content)
        {
            Task<string> result = content.ReadAsStringAsync();

            res = result.Result;
        }
    }
}

public class ClusteringObject
{
    public string Data { get; set; }

    public int NumberOfCluster { get; set; }

}

我的 post 操作 returns 0。看来，我无法将我的对象传递给 Web API 这就是它显示每个属性的默认值的原因。如何将 ClusteringObject 的实例传递到我的 Web API？

PostAsJsonAsync 会在请求中发送 ClusteringObject 作为 Body，我建议你试试 FromBody 喜欢

public string Post([FromBody]ClusteringObject _cluesteringObject)
