网络数据推送

一、通用数据推送代码
下面是优化后的代码：

private async Task<string> PostResponse(string url, string postDataStr, string accessToken)
{
    string htmlUrl = url + (string.IsNullOrEmpty(accessToken) ? "" : "?access_token=" + accessToken);
    string apiUrl = apiurl.TrimEnd('/') + "/";
    var client = new HttpClient();
    client.BaseAddress = new Uri(apiUrl);
    var requestMessage = new HttpRequestMessage(HttpMethod.Post, htmlUrl);
    requestMessage.Content = new StringContent(postDataStr, Encoding.UTF8, "application/json");
    try
    {
        var response = await client.SendAsync(requestMessage).ConfigureAwait(false);
        if (response.IsSuccessStatusCode)
        {
            var result = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
            return result;
        }
        else
        {
            var error = new { code = -999999, msg = response.StatusCode };
            return JsonConvert.SerializeObject(error);
        }
    }
    catch (Exception ex)
    {
        return $"PostResponse_token:url{{{url}}}{ex.Message}{ex.StackTrace}";
    }
}

优化说明：

1. 使用 Encoding.UTF8 替换 System.Text.Encoding.UTF8。

二、加了接口鉴权的数据推送代码：

      /// <summary>
      /// 上海联通数据推送接口 2023-4-1 lzh
      /// </summary>
      /// <param name="Url">获取令牌地址</param>
      /// <param name="postDataStr">发送数据</param>
      /// <param name="Token">令牌</param>
      /// <returns></returns>
      private async Task<string> PostTokenResponse(string Url, string postDataStr,string Token)
      {
          NLogHelp.WriteError("PostResponseToken2:" + Url + postDataStr);
          // 1、准备Url
          var requestMessage = new HttpRequestMessage(HttpMethod.Post, $"{Url}");
          // 2、准备参数postDataStr
          requestMessage.Content = new StringContent(postDataStr, System.Text.Encoding.UTF8, "application/json");
          string retString = "";
          try
          {
              // 1/  创建一个HttpClient
              var _client = _clientFactory.CreateClient("FrontendApiurl2");
              // 2、HttpClient 请求头Bearer
              _client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Token);

              var response = await _client.SendAsync(requestMessage).ConfigureAwait(false);
              if (response.IsSuccessStatusCode)
              {
                  // 3、得到结果
                  var result = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
                  retString = result;
              }
              else
              {
                  retString = JsonConvert.SerializeObject(new { code = -999999, msg = response.StatusCode });
              }
          }
          catch (Exception ex)
          {
              return "PostResponse_token:url{" + Url + "}" + ex.StackTrace;
          }
          return retString;
      }
