public string Execute(string ApiName, JObject parameters)         {             string result = string.Empty;             try             {                 string BaseUrl = this.BaseUrl;                 string ApiUrl = string.Format("{0}{1}", BaseUrl, ApiName);                 HttpContent httpContent = new StringContent(parameters.ToString(), Encoding.UTF8, "text/json");                 httpContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");                 HttpClient httpClient = new HttpClient();                   string responseJson = httpClient.PostAsync(ApiUrl, httpContent).Result.Content.ReadAsStringAsync().Result;                 return responseJson;             }             catch (Exception e)             {                 DataResult dataResult = new DataResult() { Code = (int)EResponseCode.Exception, Message = e.Message };                 result = JsonHelper.SerializeObject(dataResult);             }             return result;         }

　　

　　　　通过如下方式解决，在配置文件中新增如下配置：

<system.net>
        <settings>
            <servicePointManager expect100Continue="false" />
        </settings>
</system.net>
