我已经创建了一个 web api 项目，在值控制器中我创建了一个方法 InsertHeading，它接受三个参数并返回一个唯一的 id。该方法如下所示：-

  public int InsertHeading([FromBody]string appid, [FromBody]string type, [FromBody]string detail)
        {
            int x = 1;
            return 1;


        }

我也试过这个变种

[HttpPost]
      public int InsertHeading(string appid, string type, string detail)
            {
                int x = 1;
                return 1;
            }

当我 从soap UI 中提供如下网址时，这段代码正在运行：- http://server:port/LoggingAPi/Values/InsertHeading 。

但是，当我尝试从我的 c# 代码中调用此方法时，我遇到了 404 错误。这是我尝试过的两种方法：-

        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://xxxxx:45422/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            var append = new MasterLogInfo() { appid = "2", type = "request", detail = "test call from genesys" };

            HttpResponseMessage response = await client.PostAsJsonAsync("LoggingAPI/Values/InsertMasterloginfo", append);

            if (response.IsSuccessStatusCode)
            {
                // Get the URI of the created resource.
                Uri finalURL = response.Headers.Location;
            }

        }

方法2：-

//  client.BaseAddress = new Uri("http://localhost:53117/");
                client.BaseAddress = new Uri("http://xxxxxx:45422/");
                client.DefaultRequestHeaders.Accept.Clear();
            //    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                client.DefaultRequestHeaders.Accept.Add(
   new MediaTypeWithQualityHeaderValue("application/json"));
                var user = new MasterLogInfo();
                user.appid = "100";
                user.typeRequest = "Test";
                user.detail = "test call from genesys";

      var response = client.PostAsync("LoggingAPI/Values/InsertMasterloginfo", new StringContent(new JavaScriptSerializer().Serialize(user), Encoding.UTF8, "application/json")).Result;

            //    var response = client.PostAsync("Values/InsertHeading", new StringContent(new JavaScriptSerializer().Serialize(user), Encoding.UTF8, "application/json")).Result;


                if (response.IsSuccessStatusCode)
                {
                    // Get the URI of the created resource.
                    Uri finalURL = response.Headers.Location;
                }

            }

如果我在参数中使用 FromBody 标记，我得到 500 内部服务器错误，没有它我得到 404 错误。谁能告诉我我错过了什么。出于安全目的，我删除了插入标题的正文

创建一个表示来自帖子的有效负载的对象。然后你可以在动作参数中使用它，例如public int InsertHeading([FromBody] MyObject myObject)
