Question

这是我得到的错误：

System.AggregateException: One or more errors occurred. 
---> System.Net.Http.HttpRequestException: An error occurred while sending the request. 
---> System.Net.WebException: Unable to connect to the remote server

以下是我认为导致此问题的代码：

 [ActionName("Login")]
    [HttpGet]
    [CacheFilter(TimeDuration = 100)]
    public async Task<string> Login([FromUri]string id, string netPwd)
    {
      using (HostingEnvironment.Impersonate())
        {
            try
            {
                HttpClientHandler hndlr = new HttpClientHandler();
                hndlr.UseDefaultCredentials = true;
                HttpClient client = new HttpClient(hndlr);

                 client.BaseAddress = new 
               Uri("http://172.26.17.212/webapi_publish/api/employee/Login/" 
                 + id + "?netpwd=" + netPwd);

                // Add an Accept header for JSON format.
                client.DefaultRequestHeaders.Accept.Add(
               new MediaTypeWithQualityHeaderValue("application/json"));

                HttpResponseMessage response = client.GetAsync(client.BaseAddress).Result;

                if (response.IsSuccessStatusCode)
                {
                    dt = response.Content.ReadAsStringAsync().Result;
                }
            }

            catch (Exception ex)
            {

                dt = ex.ToString();
            }
        }
        return dt;
  }

从您收到的错误中，您似乎无法访问服务器的http端口。

请管理员检查您的网络设置是否正常，或允许此端口在防火墙中访问。

无法从远程桌面访问本地iis
