将数据从 dotnetcore api 发布到 .net api 不起作用答案

【问题标题】：Posting data from dotnetcore api to .net api not working将数据从 dotnetcore api 发布到 .net api 不起作用

【问题描述】：

我们在 DDD（领域驱动设计）环境中工作，我们有数十个使用 .Net 制作的 API。我们正在创建的最新站点是一个 dotnetcore 站点，我们希望调用所有旧的 .Net API:s。问题是我无法为旧 API 获取任何值。每次我将某些内容发布到旧 API 时，它都会变为 null。当我创建一个 dotnetcore api 时，它工作正常。 dotnetcore 调用旧的 .net API 是否存在已知问题？

旧 API：

          [HttpPost]
    [Route("GetIllustration")]
    public async Task<HttpResponseMessage> GetIllustration([FromBody] JsData illustrationRequest)
    {
        if(illustrationRequest == null)
        {
            return Request.CreateErrorResponse(HttpStatusCode.BadRequest, "Request was null");
        }
        //var modelService = modelLookupService.Get(illustrationRequest.ModelName);
        //var illustration = modelService.Get(illustrationRequest);
        return Request.CreateResponse(HttpStatusCode.Accepted, illustrationRequest);
    }

工作的dotnetcore：

          [HttpPost]
    [Route("GetIllustration")]
    public IActionResult GetIllustration([FromBody] JsData illustrationRequest)
    {
        if (illustrationRequest == null)
        {
            return BadRequest(illustrationRequest);
        }
        return Ok(illustrationRequest);
    }

返回类型不同，否则在不同类型的API中是相同的方法。

调用 .net api：

 public IActionResult Get(GetIllustrationRequest request)
      {
        var req = new JsData()
        {
            CountryCode = "DE",
            DrawSideInfo = true,
            IlXml = "XML",
            ImageSizeHeight = 123,
            ImageSizeWidth = 1234,
            LargeImageSizeHeight = 12345,
            LargeImageSizeWidth = 123456,
            ModelName = "SUPERIOR",
            ShowInside = true,
            SupplierName = "NORMSTAHL",
            TopItemName = "SUPERIOR+42",
            XposText = "HAJ",
            YposText = "DÅÅ"
        };
        return PostAsJson("/GetIllustration", req);
    }

对 dotnetcore api 的工作调用：

   public IActionResult Get(GetIllustrationRequest request)
    {
        var req = new JsData()
        {
            CountryCode = "DE",
            DrawSideInfo = true,
            IlXml = "XML",
            ImageSizeHeight = 123,
            ImageSizeWidth = 1234,
            LargeImageSizeHeight = 12345,
            LargeImageSizeWidth = 123456,
            ModelName = "SUPERIOR",
            ShowInside = true,
            SupplierName = "NORMSTAHL",
            TopItemName = "SUPERIOR+42",
            XposText = "HAJ",
            YposText = "DÅÅ"
        };
        return PostAsJson("api/Configuration/GetIllustration", req);
    }

这是实际的邮政编码：

   using (var client = new HttpClient())
            {
                client.BaseAddress = new Uri(BaseUri);
                var cancellationToken = new CancellationToken();
                client.DefaultRequestHeaders.Add("X-Content-Type-Options", "nosniff");                 
                if (!string.IsNullOrEmpty(OAuth2Token))
                {
                    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(
                        "BEARER",
                        OAuth2Token);
                }
                var response = client.PostAsJsonAsync(path, value, cancellationToken).Result;
                var stringResult = response.Content.ReadAsStringAsync();
                var result = JsonConvert.DeserializeObject<object>(stringResult.Result);
                return Ok(result);
            }

【解决方案1】：

显然 dotnetcore 由于某种原因无法处理 postasjsonasync 方法。所以我不得不手动将我的方法更改为：

                var content = JsonConvert.SerializeObject(value);
                HttpContent httpContent = new StringContent(content, Encoding.UTF8, "application/json");
                var response = client.PutAsync(path , httpContent, cancellationToken).Result;
                var stringResult = response.Content.ReadAsStringAsync();

代替：

            var response = client.PutAsJsonAsync(path, value, cancellationToken).Result;
            var stringResult = response.Content.ReadAsStringAsync();
            var result = JsonConvert.DeserializeObject<object>(stringResult.Result);
