使用ASP .NET Core

Question

为什么我的web api POST / PUT响应时间如此之慢，代码如下？ POST的json内容只是＆lt; = 1024字节。

方法1和方法2我也试过但结果相同，慢......

已经尝试禁用代理;也很慢。

        // GET API
        var testAsID = Convert.ToInt32(result);  
        var getQueryString = string.Format("CoID={0}&ArID={1}", testCoID, testAsID);  
        var response = await GetWebApiResponse(WebApiMethod.GET, controller, "GetByID", getQueryString);  
        var result = await response.Content.ReadAsStringAsync();

        //  POST
    var newAS = new ASMtnModel()
                {
                    CoID = "LKC3",
                    AsID = 0,
                    ClassID = "AR",
                    AsCode = "AS Test 1",
                    AsNameS = "AS Test 1",
                    AsName1 = "AS Name 1",
                    AsCurr = "RM",
                    AsCat1 = "ZZZZZZ",
                    AsProject = "ZZZZZZZZZZZZZZZ",
                    AsCrTerm = "CASH",
                    AsGLAcID = "",

                    AsGLScID = "",
                    AsCrLmt = 0,
                    AsCrBal = 0,
                    AsTaxType = "N",
                    AsAccStatus = "1",
                    AsStatus = "A",
                    AsDateOpen = DateTime.Now,

                    LastUpdateDate = DateTime.Now,
                    AsGstDefaultValue = "E"
                };
        var httpResponseMessage = await GetWebApiResponse(WebApiMethod.POST, controller, "Create", "", newAS);  
        var result = await httpResponseMessage.Content.ReadAsStringAsync(); 


        public async Task GetWebApiResponse(WebApiMethod webApiMethod, string controller, string action, string queryString = "", object requestBody = null)
        {
          var request = "/api/" + controller;
          if (!string.IsNullOrEmpty(action))
          {
            request += "/" + action;
          }
          if (!string.IsNullOrEmpty(queryString))
          {
            request += "?" + queryString;
          }

          var httpResponseMessage = new HttpResponseMessage();
          if (webApiMethod == WebApiMethod.GET)
          {
            httpResponseMessage = await _client.GetAsync(request);
          }
          else if (webApiMethod == WebApiMethod.POST)
          {
            string postBody = JsonConvert.SerializeObject(requestBody);
            // Method 1
            //httpResponseMessage = await _client.PostAsync(request, new StringContent(postBody, Encoding.UTF8, "application/json"));

            // Method 2
            using (WebClient wc = new WebClient())
            {
              wc.Proxy = null;
              var hostUrl = _client.BaseAddress.AbsoluteUri;
              if (hostUrl.EndsWith("/"))
              {
                hostUrl = hostUrl.Substring(0, hostUrl.Length - 1);
              }
              var fullApiUrl = hostUrl + request;
              byte[] bytes = System.Text.Encoding.ASCII.GetBytes(postBody);
              wc.Headers[HttpRequestHeader.ContentType] = "application/json";
              var resp = await wc.UploadDataTaskAsync(new Uri(fullApiUrl), bytes);

              httpResponseMessage = new HttpResponseMessage(HttpStatusCode.OK);
              httpResponseMessage.Content = new StringContent(System.Text.Encoding.UTF8.GetString(resp));
            }
